China Printed Circuit Association the CPCA, vice chairman and environmental clean club president Chen Rongxian
Recent decades, we printed circuit board industry from scratch, from small to large, rapid development. Printed circuit board industry output value from 2006 to maintain output, the output value of the status in the world. According to the report of the the famous global PCB market analyst Prismark company in March 2012, the output value of the global printed circuit board 2012 to $ 54.31 billion, printed circuit board production value of approximately $ 21.636 billion, accounting for 39.8% of the world.
PCB is the country to encourage the development of industry
PCB enterprises are many restrictions and ban will allow businesses to grow and develop great difficulty.
It can be said that the scale of the production of printed circuit board industry occupies a pivotal position in the world. However, we should clearly see their own shortcomings, 90% of the printed circuit board business for small and medium enterprises, compared with foreign enterprises scale is not big enough, the value of the products is not high enough, the level of technical and management is still lagging behind. Now is accelerate the development and enhance the self "golden era" of the printed circuit board business. April 25, 2012, issued by the National Development and Reform Commission Guidance Catalogue "industrial restructuring", again, will be included in the industry to encourage the development of printed circuit board manufacturing. Now, however, the printed circuit board business development has encountered difficulties and embarrassment.
With the further deepening of the national environmental protection work, the government environmental protection departments in energy conservation, structural adjustment, promote ecological civilization construction has done a lot to try and innovation, correctly handle the relationship between economic development and environmental protection, so interdependent, mutual promotion and achieved good results for all to see, and also has accumulated a wealth of environmental experience. Shenzhen, for example, in recent years, continued to increase municipal pipe network construction, a number of measures to increase Wetland Park, the construction of the water treatment plant in Shenzhen within a few rivers become deprived of clean water by the dark and smelly suspension years of dragon boat racing activities and therefore recover. Shenzhen's economic development has not been affected.
However, parts of the government environmental protection departments practice we do not agree with them in the day-to-day environmental work incorrectly printed circuit board industry is determined to be the same high-polluting industries and electroplating industry, its be many restrictions and ban mobilization of the printed circuit board business to move out of a certain area, considered too risky banks refuse to lend. These measures led to printed circuit boards enterprises are forced to move away from their familiar customers, suppliers away from his many years of cooperation, business development and expansion has encountered great difficulties.
Scientific development of emission standards
With embedded in the application of new technology components technologies, printed electronics, PCB industry will be more environmentally friendly.
Can explore which requires the government, society and businesses work together, brainstorming a printed circuit board industry healthy development? We would like to start a discussion, to talk about their own views.
First, the relevant government departments need to re-examine the adequacy of the environmental standards enforced by the printed circuit board industry.
Printed circuit board production process in the presence of the plating process, the environmental protection departments will be classified plating industry printed circuit board business management. In fact, the plating process accounts for only a small portion of the printed circuit board production, there is a great difference between the two industries. The 30 categories in our national economy industry classification (GB / T 4754-2011) "manufacturing categories, the printed circuit board are the major categories of computer, communications and other electronic equipment manufacturing. 2008, organized by the Ministry of Environmental Protection to develop "clean production standards - printed circuit board manufacturing" (HJ450-2008) standard has been released officially on February 1, 2009. The standard clearly states: from the date of implementation of this standard, clean production standards - Electroplating Industry "(HJ/T314-2006) involved will be required on a printed circuit board indicators instead. Printed circuit board business directly with the emission standards for control of the electroplating industry is inappropriate and not conducive to the healthy development of the industry.
Need to develop standards for emissions embodied the principle of scientific development. Control of the emission factors are not as low as possible? Surface is yes, but after careful analysis, we found that is not always the case. For example, we limited the heavy metal pollution the highest emission limits copper ion is 0.3 mg / l nickel ions was 0.1 mg / l, compare these with the emission standards in many developed countries, lower standard than they drinking a lot (China National Standard copper in drinking water content of 1.0 mg / liter). Enterprise standards, it is necessary to add more agents, heavy metal ions control anymore, but the operating costs of enterprises increased the salt content of the discharged water rose, another new pollution. Therefore, simply tightened to reduce the concentration of emission factors, and will not necessarily produce the desired economic and social benefits, should be given comprehensive consideration in these areas, in order to effectively promote the healthy development of the industry.
Secondly, the industry associations should actively coordinate relevant government departments and professional bodies to develop pollutant emission standards for the printed circuit board industry. Has a unique production process, the printed circuit board industry and professional bodies should conduct a detailed understanding of the industry's production process, combined with the current level of development of the environmentally friendly processing technology to develop a suitable pollutant emission standards. Either the environmental protection work to produce results, while enabling the printed circuit board industry have made great progress. With the advances in environmental technology and printed circuit technology constantly tightening of emission control indicators, China's environmental protection industry phased and orderly way to move forward. For example, buried in the component technology, digital inkjet print printed electronic technology, the application of new technologies, production wastewater biochemical treatment technology will make the printed circuit board industry more environmentally friendly.
China Printed Circuit Association has been doing work in this area in line with the relevant government departments and professional bodies. In 2009, completed for a of electronic industrial pollutant emission standards - electronic components and printed circuit boards "national standard draft for approval. Currently, after re-evaluate plans to merge five standard in the electronics industry for "electronic industrial pollutant emission standards - electronic materials, electronic components and printed circuit boards, semiconductor devices, electrical vacuum and flat panel display devices, electronic end products" national standards. We very much expect the standard as soon as possible awarded to effectively guide the printed circuit board and the entire electronics industry pollutant emission control work.
Finally, we call on the printed circuit board enterprises to strengthen self-discipline, enhance the sense of social responsibility, the cause of environmental protection in the first position. Companies just have to accept seriously operate according to specifications, and to increase investment in the cause of environmental protection, and actively introduce new advanced techniques and technologies, strengthen management, to establish a new image in the public eye, in order to get more opportunities for development, in order to get the government and society more support.
Then the printed circuit board industry truly embarked on a road of healthy development.

PCB industry chain onto the era of national brand management
China PCB development to today, has no shortage of the amount, and no shortage of the number, but also no shortage of proportion. The number, the number of PCB enterprises in China, one to two thousand, the largest in the world; yield, production area of the number of the highest in the world; proportion PCB China accounted for 40% of the global share, the world's largest; output value of China's PCB production value of 152 billion yuan (2011) has the first in the world for many years.
China PCB, leaving a shortfall of what? Lack of high value-added PCB, lack of PCB enterprises enter the world, the lack of world influence corporate brand.
In addition, China is still missing a complete PCB industry chain. Our special equipment, instruments, specialty chemicals and materials, the main material CCL enterprises in product variety, the parameters of performance, accuracy, reliability, stability, there is a large gap between the equivalent to a world-famous brands of similar products. For some cases, such as laser drilling, laser cutting, laser imaging apparatus, the character, the solder mask, the line printing machine, a biaxial shooting machine, plating (nickel, gold, silver, tin, OSP, etc.) gage, thermal resistance bulk bulk material tester, etc., as well as the photosensitive dry film, film negatives, photosensitive solder resist ink, a variety of high-performance chemical additives, special performance CCL material, these devices / equipment, materials are still not be able to adapt PCB technology development needs the PCB enterprises are still easy to think the import of foreign brands.
Organized the third national brand contest to our entire PCB industry and its industrial chain to achieve localization and national brand bigger and stronger. China's economic rise, must be supported by national brands; brand image of the country, can not do without a national brand; powerful of the powerful PCB can not be separated from national enterprises in China.
We see the global competitiveness of the enterprise has its own well-known brand. Inseparable from the brand to create a national core competitiveness, good brand image is a valuable tangible assets of the enterprise. National brands is the elite of the industry, the pride of the nation, is the affirmation of companies and products but also the honor and flag.
We are committed to the establishment of a national brand and build, is to realize the powerful PCB industry, to keep pace with the world-class enterprises, is an effective way to build a strong and prosperous renaissance dream of our entire PCB industry chain and methods.
We Chinese people should be respected, outstanding national companies and brands, so we use domestic products to support domestic products, preferred national brand products, the PCB industry chain from product management embarked on the era of brand management.
We have been on the road, the road is very long, believe that the end of one day to achieve the the PCB national enterprises in China will be among the world's advanced forest.

China Printed Circuit Association CPCA chairman by radium

From a macroeconomic point of view, China's economy as a whole have come down than expected, we see now is no longer 9%, 8% growth, but the growth of about 7.5%. In 2013, the national economy is still likely to remain in growth of about 7.5%, a level of medium-sized. Decline in GDP growth, CPI is also stable at around 3 percent. Fiscal revenue digit growth for the first time, according to analysis of the Chinese Academy of Social Sciences, the Bank this year's "money supply" will still be tight.
Never run, the growth of our country, the incremental come from?, Stressed that China's economy as a whole is the quality of growth, rather than growth in the number. Before a word called "rapid and healthy growth", this sentence may rarely mentioned after 2013. Speaking from the national level, the government is more emphasis on "high-efficiency, high-quality, sustainable development". All industries, particularly in the electronic information industry, rigid rise of the overall cost impact on the industry is very large, which the enterprise is a big challenge.
From the microscopic point of analysis, for enterprises, the loose surface of the whole environment is still not been a fundamental change. In 2008, when the international financial crisis, we have to worry about the small and medium-sized enterprises will be affected, but the state has invested 4 trillion yuan, have not been greatly affected due to the relaxation of the "money supply". But in this period of time, some enterprises that appear to be eliminated, it is very natural.
Industry better than last year this year
Analysis from a macro perspective, the 2013 PCB industry is relatively better than 2012 better, and the whole industry should remain relatively stable growth.
In the current global economic situation, the internal growth of China's economy has been greatly affected.
Analysis from a macro perspective, China's PCB industry in 2013 relative than 2012 better, the whole industry should remain relatively stable growth. Each enterprise will have different performance, and some fast-growing enterprises, some enterprise growth slow, possibly even negative growth, and have a great relationship with the product and customer structure. Moment, the expansion of production capacity relative to the past will be more cautious.
For counterparts in Japan and Europe and the United States, compared with us, they are faced with the situation will be more severe, most Japanese companies was not ideal.
Transformation and upgrading hardware and software combination
Looking ahead to 2013, the PCB industry enterprises "optimism index" and Europe and the United States, is above them.
We should enhance its own internal capacity. Investment in the future investment in the equipment, plant on the land, or needs? Same time, we must also consider the software, including human resources, lean manufacturing, channels, especially research and development. If the future of our business is the major input and effort confined to the hardware, so that our enterprises should take to think about, whether it is worthwhile to spend so much money to invest, this is a big problem we are facing now, the artificial aspects such as recruitment and so there are a lot of problems.
Looking ahead to 2013, the the PCB enterprises "optimism index" is higher than the PCB enterprises in Europe and America, so the printed circuit industry associations and industry colleagues are now doing the work actually is gradually leading the trend of the global PCB industry. However, technically, compared with the advanced countries there are still a big gap, but we have full confidence to meet the challenges. In 2013, we must seize this opportunity to "upgrade" to make our place in the world, this is the mission and responsibility of the China Printed Circuit Association. May the new year, we have a new breakthrough in the PCB career.

Natural selection: pcb copy board faces transformation

Fri, 12 Apr 2013 08:06:20 +0000

In the first plenary meeting of the new session of the State Council, Li Keqiang, for the economic development of the situation at home and abroad made a careful analysis, and reiterated a "steady" and "into" two-pronged. In Li Keqiang, into the "key to rely on economic restructuring," to build an upgraded version of the Chinese economy. " He was very serious participants said: "Chinese economy to today not transition we unsustainable". By the same token, pcb copy board in this highly competitive market environment, a lot of uncertainties and destabilizing factors, some even very difficult moment look at how to sustainable development pcb copy board? Natural selection, and how the transformation is a test of our wisdom.
Pcb copy board homogenization speed up the transition to innovation
There is no denying that the homogenization of the era is already upon us. Major brands in order to save the cost of production, they need just a brand, a name. They do not need to own factories and R & D team, because that would lead to unnecessary expenditure. So you will see close to the same as the product of the different brands, you will see the same chipset / board products provide the same performance and functionality. Homogenization of the enterprises are from the pcb copy board, chip decryption source began to break, the emphasis on innovation and transformation. Domestic federal Science and Technology Co., Ltd. is the pcb to board, pcb design, the IC reverse design, hardware and software development and secondary development of the original prototype micro-innovation services to make their own products to the good development of diversification and differentiation of colorful road.
Marketization boost pcb copy board transformation to the people's livelihood
In the process of change in the market economy, pcb copy board we should always pay attention to the livelihood of the people required, grasp of market dynamics in order to become bigger and stronger, personalized innovation, strengthen pcb copy board according to the livelihood of the people required to shift to the localization. To grasp the livelihood of the people required include to have the ability to predict the development of the market trend to make products to meet the needs of the times, which requires us to always understand new technology products to foreign markets, and in the shortest possible time and the lowest development costs to complete the upgrade and replacement to accommodate domestic livelihood of the people is required.
The cheap bit spawned pcb copy board transition to high-end
Due to domestic and foreign markets and policy changes to increase environmental governance requirements, the pcb industry in China will enter a new era of re-adjustment and layout. Used to the expense of the sustainable development of enterprises at the expense of low-cost, low-level copy pcb board products to participate in the market competition has become obsolete, and the development of the electronic circuit industry in China to pollute the environment as the era of the consideration will also go a longer complex return. Pcb copy board facing the grim situation of rising manufacturing costs, manufacturing and business management as well as the cost impact to grasp industry changes in the internal and external environment, must also face new transformation from the enhanced high-end copy pcb board products in the global market competitiveness efforts to win more independent intellectual property rights, technology win.
Natural selection, pcb copy board derived copy, but has passed environmental screening towards innovation and transformation required to meet the people's livelihood and the field of high-end technology. pcb copy board enhanced the learning experience skills and flexible use of to get the skills, not only in line with Darwin's theory of evolution, but also an indispensable reverse New World research techniques.

The circuit board stratified improve research

[Back]

July 2006 implementation of the circuit board assembly had lead-free, the tradition has been used for over 50 years 63Sn/37Pb welding materials SnAgCu (Sn96.5% / Ag3.0% / Cu0.5%) instead of melting point from 187 ° C raised to 21 7 ° C, the corresponding welding temperature was raised to 240 ° C -260 ° C from 220 ° C to 230 ° C, the circuit board must undergo a temperature above the melting point of the soldering time more than 50 seconds, the circuit board to absorb heat, increase, circuit boards must improve the heat resistance is associated with. In the past year, the circuit board has been plagued by hierarchical circuit board manufacturers.
The mechanism of the circuit board layered circuit board endothermic, the different expansion coefficients between the different materials forming the inner stress, if the resin with a resin, a resin with a copper foil adhesive force enough to resist the internal stress will be generated stars layer, the solution to the hierarchical idea is: 1. Production process control as much as possible to ensure that the board has the best resistance to stress capacity: 2. Use the superior performance of the material to reduce internal stress. The article hope through research, the dual constraints of cost and quality, to find the best solution to solve the problem of delamination, with the lowest cost. The idea is to proceed from the study hierarchical experimental design factors layered material selection, circuit board manufacturing process control to the whole process of the circuit board assembly, system analysis. This research project costing 25 million cost of the test material, which lasted more than three months, and ultimately enhance the competitiveness of the company's point of view, from a cost and quality control, propose solutions layered three options. The experimental results are applied to the practice of Company A, good economic returns, reduce the cost of customer complaints a month about 30 million, a decrease of approximately $ 800,000 of the cost of waste, to obtain more than the expected benefits.

Line MILL Sun solder process, screen printing circuit board solder mask. Photographic original plate of the pad on the printed circuit board is covered so that it is not in the exposure to ultraviolet radiation, and the solder protective layer after UV irradiation is more well adhered to the PCB surface, the pad is not subject to ultraviolet light irradiation, the exposed copper pad, so HAL usually pewter.
Sun solder process can be divided into three procedures:

Lines MILL procedures for exposure. To check the exposure box before exposure polyester film and the bezel is clean, if not clean should be timely and anti-static cloth to wipe clean, and then open the the exposure machine's power switch, and then turn on the vacuum button to select the Exposure program, shaking exposure shutter not started before the exposure, exposure machine should be allowed to air exposure five times, the role of the "empty exposure enables the machine to enter the saturated state, the most important is the UV lamp energy into the normal range . If you do not "empty exposure the exposure lamp energy may not have access to the best working condition. Will make the printed circuit board in the exposure problems. After the empty exposure "five times, exposure machine has entered the best working condition before the camera bottom plate position to check the quality of the bottom plate is qualified. Check the bottom plate on the membrane surface if there is pinhole and the exposed portion of the light, the graphics are consistent with the printed circuit board, because it will check photographic Diban avoided because some unnecessary reason the printed circuit board rework or scrap.

Drying solder mask is usually a visual positioning silver-halide Diban, congruent alignment hole of the bottom plate of pad PCB pad with tape can be fixed exposure. Encounter in alignment sun solder commonly used visual positioning silver-halide Diban, congruent alignment hole of the bottom plate of pad PCB pad, exposure can be fixed with tape. Many problems encountered in the alignment, for example, because the bottom plate with the temperature, humidity and other factors, temperature and humidity control, the camera bottom plate may be reduced or enlarged deformation in the sun when the solder resist, photographic bottom plate and the printed circuit board pad is not exactly. See bottom plate pad PCB pad in the bottom plate down, how much difference, if the difference is small, the whole hot air usually on pewter, then there is no big problem selenium solder mask. Big difference, only to re-piracy, try to make the bottom plate pad coincidence. In the bit before, you should also pay attention to the bottom plate of the membrane surface is turn anti ensure the surface of the membrane in a bit down, up, the membrane surface is scratched, resulting in the bottom plate of light exposure, so that drying out printed circuit board without exposure at the solder material, can cause serious PCB scrap. Also, note that sometimes the imposition of the bottom plate and the printed circuit board graphics do not coincide, usually cut the imposition Diban along the edge of the puzzle, and then fight to the entire printed circuit board for good exposure. The above problem is the attention before formal exposure selenium solder mask.

Then, the sun solder mask should be checked before exposure to the printed circuit board by vacuum suction box cover. Vacuum overlying pressure should be sufficient without the presence of exposed gas. If the gas causes the dew ultraviolet light shines into graphic along the side of the board, resulting in shading at the exposure, developing afford sometimes encountered the case of single-sided exposure, in this case, no single graphics on one side with a black cloth The exposure lamp emitted UV separated If you do not have a black cloth, UV graphics transmitted to the pad in the pad hole solder material after exposure, development can not afford to. Graphics on both sides of the exposed inconsistencies in the printed circuit board, the first screen printing side of the solder, and then single-sided exposure, developing, screen printing the other side of the solder resist, because both sides of screen printing exposure, there are side complex graphics pad more shading part, while the other side of the shading part, the irradiated ultraviolet light through the side to the other side, blackout side after ultraviolet irradiation, in the developing afford Movies cause rework or scrapped. In the exposure process, will encounter no drying of the printed circuit board when cured after screen printing, this case, in the the photoplate on bit causes the solder material touches, but the printed circuit board rework found quit, especially most of the printed circuit board, there is no drying is necessary to put in the oven to re-drying. These are exposure occurred during the process, so we must carefully check the timely detection and timely solutions.

Lines MILL second step is developing. Developing operation is generally carried out in a developing machine the control developer temperature, transmission speed, spray pressure of the developing parameters, it is possible to obtain better developing the effect. Developing the light-shielding portion with a developing solution to remove the solder resist on the pad. The developing solution is one percent of anhydrous sodium carbonate, the liquid temperature is usually in the between thirty to thirty-five degrees Celsius. Before the formal development to the developing machine is warming up, the solution reaches a predetermined temperature, so as to achieve the best development results. Developing machine is divided into three parts: the first is a spray segment, mainly using high-pressure injection over anhydrous sodium carbonate, so that the the unexposed solder resist is dissolved down; the second is the water wash section, the first is the use of the washing of the high-pressure pump, the first the residual solution is washed clean, and then enter the circulation washing, washed thoroughly; paragraph 3, before and after each drying section, drying section an air knife is hot air board to dry, and then the temperature of the drying section the board drying. The solder resist layer is not sufficient to determine the correct time of development by showing points, showing points must be kept at a constant percentage of the total length of the developing section, showing too close to the outlet from the developing section, unexposed developing cause the PCB board unexposed residue of the solder resist layer may be left in the surface of the plate, if the show is too close from the inlet of the developing section, the solder resist layer is exposed due to Q. contact with the liquid developer is too long, it may be soaked eclipse become scared and dull. Usually showing control in the 40% -60% of the total length of the developing section, Also, note that in the developing time, it is easy to scratch board, usually the solution is put in developing board operator to wear gloves, board, gently put, there is the size of the printed circuit board sizes, so try to size almost put together, put the board to maintain a certain distance between the board and the board, in order to prevent the transmission when the board is crowded, resulting in the phenomenon of the "card board".

Not continuous deflection of such multilayer flexible circuit boards made of soft insulated information with soft materials, soft insulating substrate, a multilayer circuit board the finished product required shape. But due to the limitations of the electrical design, such as to the desired conductor resistance requirements with a thickness of the conductor, or for the desired impedance or capacitance requirements in thick insulating isolation between the signal layer and the ground layer, therefore, the waste application when it was forming. Term "moldable defined for: the multilayer flexible circuit board member shape having made the required capacity, and in the application can not be deflection. Avionics unit internal wiring applications. At this time, the claim stripline or the conductor resistance of the three-dimensional design space is low, the capacitive coupling or circuit noise is minimal, and the interconnection end portion can be smoothly curved in a 90 ° item polyimide film made of a multilayer flexible circuit board B to achieve this The colors of the wiring task can be further divided into a plurality of multilayer flexible polyimide film high temperature, flexibility, and good electrical and mechanical characteristics and the total of all interconnections of the member cross-section in order to achieve this, which traces Partly The circuit member, and the adhesive tape together to form a printed circuit beam.

Basic knowledge of the flexible circuit board

It is now relatively rare in that soft, rigid or rigid-flex circuit board with say it several layers of circuit boards usually, with the flexible circuit board production ratio increased from time to time and just the application and promotion of the flexible circuit board. Circuit boards made of soft insulating substrate called a compound of the circuit board, said flexible circuit boards or flexible circuit boards rigid-flex rigid-flex circuit board adapted to today's electronic products to the high-density and high reliability, miniaturization , lightweight direction development needs, but also to meet the strict economic requirements and the needs of the market and technology competition.

Flexible circuit boards early 1960s has been widely used. Country and abroad. In the sixties began production applications. In recent years, with the global economic integration and open City tasted the introduction of technology to promote its usage from time to time in the growth of some small and medium-sized rigid PCB factories are cashing in on the opportunity to use the soft to hard to do process, the use of existing equipment, tooling tools and process improvement, transformation and production of flexible circuit boards to meet the needs of soft the PCB amount of from time to time growth. In order to further understanding of the PCB here for an exploratory introduction of flexible PCB technology.

Classification, advantages and disadvantages of a flexible circuit board

1. Flexible circuit boards Category

Soft PCB is usually based on the number of layers and structure of the conductor classified as follows:

1.1 single-sided flexible circuit boards look coating or overlay. The insulating base material used, only one layer of single-sided flexible PCB conductor. The type of application with the product type. The commonly used insulating polyester, polyimide, polytetrafluoroethylene, soft epoxy - glass cloth.

The single-sided flexible PCB can be further divided into the following four categories:

1 without a covering layer single-sided connection

Wire appearance without overburden. Like the usual single-sided rigid circuit boards. This type of product is the cheapest, such flexible PCB conductor patterns on the insulating base. Are often used in non-critical Applications Environmental Protection. Interconnect soldering, welding or bonding. Commonly used in the early days of the telephone.

2 connected on one side of the cover layer

Just according to customer requirements in wire appearance of multi-layer overlay. Cover pad exposed to such and compared to the former class. Simple in the region of the end portion is not covered. Requires precision may be applied in the form of access holes. The largest single-sided flexible circuit boards, the most widely used, widely used in automotive instrumentation, electronic equipment.

3 No covering layer double-sided connection

Open a passage hole in the insulating base material of the pads at the connection in the front and back sides of the wire can be connected to the type of connection for rent. In order to do this. This passage hole may be punched in the desired position on the insulating substrate before etching or other mechanical means. For installation on both sides, devices and require soldering to the path at the pad area without insulating substrate, such pad area is usually removed by chemical methods.

4 double-sided connection of the cover layer

Allowing it to both sides can be terminated, such differences in class appearance with a layer of overburden. However, the cover layer via hole. And still adhere to the coating. Such flexible PCB is made of information by the two layers of insulation and a layer of metal conductor. Be used in place need covering layer and insulated from each other around the apparatus itself and also insulated from each other, the end of the positive and negative are connected.

1.2 double-sided flexible circuit boards Its main advantage is to increase the wiring density per unit area. Metal may, metalized holes, and there is no covering layer is divided into: a metalized hole, non-metalized hole b of the cover layer, the cover layer c metalized holes, without a covering layer d through holes, with less application of the coating layer without a covering layer of double-sided flexible PCB. Double-sided flexible circuit boards B has two conductors. Kind of double-sided flexible PCB applications and advantages of the single-sided flexible PCB.

1.3 multi-layer flexible PCB

Multi-layer lamination technology, flexible multi-layer PCB, such as rigid multi-layer circuit board. This Layer three flexible PCB can be made of a multilayer flexible PCB easiest multilayer flexible PCB single-sided circuit board on both sides is covered with two layers of copper shielding layer is formed on the flexible PCB electrical characteristics equivalent to the coaxial wire or shielded wires. The most commonly used multi-layer flexible PCB structure is a four-layer structure, inter-layer interconnect with metallized holes, the middle of the second floor is generally the power and ground planes.

Such as a low dielectric constant. With a polyimide film as a base material made of a multilayer flexible pcb board, the advantages of a multilayer flexible circuit board substrate film is light weight and has excellent electrical characteristics. Approximately 1/3 lighter than rigid epoxy glass cloth multi-layer PCB board weight but it lost its single-sided, double-sided flexible PCB excellent flexibility, most of these products do not require flexible

The multi-layer flexible PCB can be further divided into the following types:

But the center of the local and at the end bonded together, a flexible insulating substrate, a multi-layer circuit board finished requirements for deflection: circuit boards kinds of structures are often many-sided or double-sided microstrip flexible PCB end on both sides are bonded together. Highly flexible. To having the desired electrical characteristics, such as the characteristic impedance of the performance and it is interconnected rigid circuit board to match each of the wiring layer of the multilayer flexible PCB member, the design of signal lines required in the ground plane. For highly flexible, thin layer of lead layer on the availability of suitable coating, such as polyimide, instead of a thick layer of a laminated coating layer. Z metalized holes so that the flexible wiring layer between the surface to achieve the desired interconnection. Such a multilayer flexible PCB is most suitable for applications requiring flexibility, high reliability and high density design.

Such as polyimide film, a multi-layer circuit board 2 flexible insulating substrate deflection: the end of the finished product, such multi-layer flexible circuit boards with a soft insulating material. Made of laminated plywood. The laminated After losing the inherent flexibility. When the design requirements to maximize the use of a thin film of insulating characteristics such as low dielectric constant, the thickness of the homogeneous medium, the lighter weight and capable of continuous processing characteristics such flexible circuit board, for example, polyimide the film insulation manufacturing of multilayer PCB about one-third lighter than the weight of the epoxy glass cloth rigid PCB

Series ended wiring twice as large capacitive load caused by the delay time increment of approximately than corresponding parallel end wiring the series termination circuit board circuit has the ability to drive several parallel load line. The short-term due to the capacitive load so that the edge speed to slow down and drive the gate delay time increases, but the series end crosstalk wiring than the parallel side wiring to small, mainly because of signal amplitude is only two points in the series-end wire routing one of the logic swing, thus switching current parallel termination is only half of the switch current signal energy is small crosstalk is also small.

Circuit boards how to do a good job competence
A: To clear design goals
Received a design task, we must first clear its design goals, the ordinary circuit boards, high-frequency circuit boards, small signal processing circuit board or both with high frequency and signal processing circuit board, the ordinary circuit boards, as long as do layout neat, mechanical accuracy of the size can be, if the load line and the long-term, it is necessary to use certain means of disposal, reduce the load, the long-term to strengthen the drive, the focus is to prevent long-term reflection. When the board has more than 40MHz signal line, it is necessary for these signal lines are special considerations, such as the problem of crosstalk between the lines. If the frequency is higher to some of the length of the wiring, there is more stringent restrictions, according to the distribution parameters of the network theory, the interaction between the high-speed circuit and its connections is the decisive factor, the system design can not be ignored. Door improvement of transmission speed, the signal line will be a corresponding increase in the objection, the crosstalk between adjacent signal lines will increase in proportion to the usually high-speed circuit power consumption and heat dissipation is great, high speed circuit board should be taken seriously enough.

These signal lines need special care, when the panel millivolt even microvolt weak signal. Small signal is too weak, are very vulnerable to interference from other strong signals, shielding measures is often necessary or will greatly reduce the signal-to-noise ratio. That the useful signal is noise and can not be effectively extracted.

The physical location of the test point, the board Commissioning must also be taken into consideration at the design stage. Test point isolation and other factors can not be ignored, because some small signal and the high frequency signal is not directly probe added to the measurement

If the board layers, in addition to take into account other relevant factors. The components of the package shape, the mechanical strength of the board. Before doing the circuit board to make a pretty good idea of the design goals.
II. Solution components placement and routing requirements

Some special components have special requirements, placement and routing know. Example, the LOTI and APH used analog signal amplifier, analog signal amplifier to have a smooth power requirements, small ripple. The analog signal as far away as possible from the local power devices. OTI board, local small signal amplification also specifically plus a shield to shield off the stray electromagnetic interference. ECL technology, the the NTOI board GLINK chip is used in large power consumption, severe heat, the heat dissipation problem required special consideration must be carried out in the layout, the use of natural cooling, should GLINK chip on the air circulation is relatively smooth place, and the heat comes out of other chips can not constitute a big impact. If the board is equipped with a horn or other high-power devices, it is possible to cause serious pollution that should be taken seriously enough power.

Components layout considerations

Connection components close to try to put together a factor in the layout of the components of the first thing to consider is the electrical properties. Especially for the high-speed line, the layout is necessary to make it as short as possible, to separate the power signal and small signal devices. Meet circuit performance, but also consider the components neatly, beautiful, easy to test the mechanical dimensions of the board, the location of outlets, also needs to be carefully considered.

Circuit boards, especially first thing to consider when on the ground in the high-speed ECL circuits, high-speed system interconnect line propagation delay time system design factors. The transmission time of the signal line has a great impact on the overall system speed. Although the circuit block itself at high speeds, but on the base plate with the common interconnection line (each line 30cm length the 2n delay amount) to bring the delay time increases, the system speed can be greatly reduced. Like the shift register synchronization counter synchronization member is preferably placed on the same piece of the plug-in board, because the transmission delay time is not equal to the type of plug-in board clock signal, the shift register may make the main production error, if it can not be placed on a board , then the synchronization is critical areas, the length of each plug-in board connected to the clock line from a common clock source must be equal.

Wiring consider.

I will have more than 100MHz board with high-speed signal lines need to design, with the completion of the fiber optic network design OTNI and star. Here will introduce some basic concepts of the high-speed line.

1. Transmission line

The reflection of the main signal rise during the production will be submerged. Red, recoil, and ringing no longer present, the printed circuit board of any one of the "long" signal path can be regarded as a transmission line. If the circuit board of the transmission line delay time rise time is much shorter than the signal. For most MOS circuit, much larger than the line propagation delay time rise time, so take the line length in meters without signal distortion. For faster logic circuits, especially the ultra-high-speed ECL integrated circuits, due to the faster edge speeds, in the absence of other measures, trace lengths must be greatly reduced, in order to maintain the integrity of the signal.

Fast falling edge, TTL Schottky diode clamp method, there are two ways to make high-speed circuit in a relatively long line work without serious waveform distortion. So that the amount of overshoot is clamped one diode drop lower than the ground potential level, which reduces the amplitude of the back of the recoil, slower rising edge overshoot allowed, but it is in the state where the level "H circuit relatively high output impedance (5080Ω) attenuation In addition, due to the level "H state immunity, the recoil problem is not very prominent, the HCT series devices, the use of a Schottky diode clamp combination and series resistor termination method, the improvement effect will be more obvious.

The higher the bit rate, and the faster edge rates, when the signal line fanout. TTL shaping method described above is somewhat lacking. Because the line there is a reflected wave, high bit rate will tend to synthesis, causing serious signal distortion and lower anti-interference ability. Therefore, in order to solve the problem of reflected ECL system usually use another method: the line impedance matching method. This method enables the reflection control signal integrity is guaranteed.

Slower edge speeds practices TTL and CMOS devices, strict, he said. Transmission line is not very much in need of high-speed ECL devices faster edge speeds, the transmission line is not always needed when using the transmission line, able to predict interconnect delay and impedance matching to control the reflection and oscillation advantages. 1

Connection distance (3 capacitive load resistive load (the number of fan-out) 4 (Line Termination) 5 allows recoil and overshoot percentage (AC immunity and the reduced level) to decide whether the transmission line. factors are the following five. 1 signal edge rate.

2. Several types of transmission line

Circuit boards typically 110Ω twisted pair. A coaxial cable and twisted pair: often used in the connection between systems. The characteristic impedance of the coaxial cable typically have 50 ohms and 75Ω.

Microstrip line on the printed circuit board 2

The microstrip line is a strip guide (signal line). Between the ground plane with a dielectric isolating. If the distance between the thickness of the lines, the width of the body and the ground plane can be controlled also can control it the characteristic impedance of the microstrip line characteristic impedance Z0:

Wherein: Er is the relative permittivity of the dielectric material of the circuit board

6 is a dielectric layer thickness

For the line width of W

t for the thickness of the lines

Depends only on the dielectric constant of the contents with the line width or interval. Unit length of the microstrip transmission line delay time.

3 in the printed circuit board striplines

The strip line is a line placed in the copper strip in the middle of the dielectric between the two conductive plane. If the distance between the line width and thickness, the dielectric constant of the medium and the two conductive plane is controlled, then the characteristic impedance of the line is controllable stripline characteristic impedance acetate:

Where the distance between the: b two ground plate

For the line width of W

t for the thickness of the lines

Per unit length of stripline transmission delay time and the line width or spacing depends only on the relative dielectric constant of the medium used is irrelevant. Likewise.

3. Terminated transmission line

The transmission line is said to parallel side wiring. Mainly in order to obtain the best electrical performance, the receiving end of the line with a resistance equal to the line characteristic impedance termination. Including the driver distribution negative circuit board using

Termination resistor series with a capacitor 104 to form AC termination circuit, sometimes in order to save power consumption. Can effectively reduce the DC loss.

Terminal of line terminating resistor, the drive and the transmission line is no longer connected in series between a resistor. This termination is called the series termination. Long line overshoot and ringing in the circuit board to control the damping can be used in series or series termination series damping is small resistor in series with a driving gate output terminal (usually 1075Ω) to achieve this damping method is suitable for controlled with the characteristic impedance of the line associated with (backplane wiring, circuit board ground plane and most around the wiring.

Series terminated when the series resistance value output impedance of the circuit (driver door) and equal to the characteristic impedance of the transmission line there is a disadvantage of using lumped load only in the terminal and the transmission delay time is longer series associated client terminal. by redundant series terminated transmission line to be overcome.

4. Non-terminated transmission line

Transmission line can be used in the case of no series termination or parallel termination, if the line delay time rise time is much shorter than the signal. If a non-end wiring two-way delay (signal on the transmission line and from the first time) is shorter than the rise time of the pulse signal, then the recoil caused due to the non-terminated about 15% of the logic swing. The maximum opening length of the route is approximated by:

Lmax
Wherein: tr is the rise time

tpd unit line length transmission delay time

5. The analogy of several termination methods

Exactly what kind of wiring and a series of parallel-side end wiring have their advantages. Or two, depending on the designer's preferences and system requirements. The main advantage of the parallel-side wiring is complete transmission system speed and signal online without distortion. Long-term
Drives the gate of the load will not affect drive long-term transmission delay time, and it will not affect the signal edge speeds, circuit board, but will allow the transmission of signals along the long-term delay time increases. Drive a large fanout load distribution along the branch short-term, rather than as series termination as required in the load line terminal.

Circuit board production in the next few years, China will account for 45% -50%

Wed, 10 Apr 2013 04:01:24 +0000

Circuit board production in the next few years, China will account for 45% -50%

PCB Industry Association (CPCA), vice chairman and secretary general Wang Longji 14 at the 2013 Shanghai International Expo press briefing on circuit board production and sales in 2012 accounted for 40 of the total global production % is expected in the next three to five years will be close to 45% -50% of the global.

The circuit board is one of the important parts of the electronics industry, the role of support and connection to the electronic components. China CPCA, according to statistics, in 2006 China's PCB output value has surpassed Japan to become the world's first. Despite the scale of the industry accounts for about four percent of the world, but China's PCB industry in the overall technical level, still lags behind Japan, China, Taiwan, South Korea, the United States, Europe and other places. "Since local enterprises in China continues to grow and the overall upgrading of technology is expected to last three years of production and sales will be close to 45% -50% of the world, and among the most advanced in the world", said Wang Longji .

Circuit board industry Association, said not long ago by the radium in 2013 despite the external environment facing the entire electronics industry still has a high uncertainty, but the circuit board practitioners still own competitive advantage confidence and foreign counterparts phase than domestic enterprises to support industrial development has a strong domestic market, labor costs still has a comparative advantage; compared to Southeast Asia, India, Brazil and other countries, Chinese enterprises have unparalleled complete industrial chain supporting printed circuit board.

At the same time, however, in the expert opinion, the circuit board industry in China is also facing restructuring, companies need to gradually shift from natural elements and investment-driven growth to innovation-driven quality growth.

Related news the first quarter of 2013, the Mainland and Taiwan circuit board with the increase in output value

Last year, the European debt crisis and other negative factors, TPCA, IEK statistics, last year, Taiwanese firms circuit board production value of 5,218 billion yuan, 3.08% annual growth rate still better than the previous increase of only 0.84%, and last year was a quarter by quarter growth trend, in the fourth quarter climbed to an annual peak. Taiwan Printed Circuit Association (TPCA), IEK estimates that the first quarter of the Taiwanese firms PCB output value of 1,320 billion yuan, an increase of 6.8% compared to the same period last year. Listing cabinet factory lines revenue in January this year, Jing Peng Industry (2355), Kinsus, Asahi Soft electronic record high; Tripod Technology is reaching a new high of 21 months, Jia Total Industrial record times.

Circuit board production efficiency in China

Wed, 10 Apr 2013 03:04:16 +0000

Circuit board production efficiency in China

The development of printed electronic circuits and circuit boards. The main feature of the circuit board circuit board within the existing high-speed optical signal transmission optical structure, develop new products to seize the market or expand into new markets. There are lower speed signal transmission power (line) road structure; light printed circuit board signal light transmission.

Any country or industry will encounter in the process of development by the unlimited supply of labor to the limited provision of labor changes, most of the circuit board business is a labor-intensive areas. The labor force of the country is able to provide unlimited continues? The obvious answer is actually negative. That is, "Lewis turning point".

Circuit board industry in China has begun to face the problem of employing shortage. The circuit board industry, the goal should be to change the mode of production, increase productivity, the adjustment of product structure, increase value-added products. Of course, more importantly, to achieve the optimization and upgrading of circuit boards and structural adjustment, in fact, the shift from labor-intensive products to improve productivity and high value-added products (upgrading of industrial structure)

Transfer of production bases problems

Such as the 1980s in Europe and the United States, Japan and other labor-intensive and low value-added circuit board products transferred to China and other labor abundant low-wage countries and regions to processing and production, developed countries generally labor-intensive, low value-added the transfer of production to labor-abundant and low-cost local or foreign. In order to maintain high profits. The circuit board but this method of copying States can business? Probably is problematic for the following reasons:

Migrate to the domestic, distant, first. This will bring pollution and investment issues, but also consider China's national policy (such as rural policy, population, etc.) at the same time, relying on the surplus labor, low wages are not durable meter, is clearly not the fundamental way out.

Industrial Park into the electronic circuit is not feasible. The country has established a plurality of electronic circuits Industrial Park, followed by. Although the circuit board to solve the pressure of environmental maintenance and energy savings, but can not fundamentally solve the problem of labor and cost.

Relocation abroad. Full labor such as Vietnam, India and other countries. But we must consider first, raw and auxiliary materials, resources (water, electricity, etc.) and the supporting transportation is not an easy task; Second, the policies of these countries there are a lot of variables, fix, easy to go into the difficult even bankruptcy of trouble.

Changes in production methods to improve production efficiency

This is the way of the developed countries and regions walked or is still going. In June 2009, I see the circuit board products enterprise automated production practices, the use of automated production (especially in the low-end products). Spaced production equipment, the operator can not see, that more than 100 people (mainly management and adjustment, maintenance personnel) yield and output value is more than thousands of circuit board business in China. This marked the automated manufacture of printed circuit boards is a good way out. This is to improve the level of automation of production, a significant reduction in the operating personnel, but also to improve product quality and production efficiency, reduce production costs, improve enterprise efficiency.

The optimization and upgrading of the adjustment of product structure and thus

Increase the proportion of high-end products (high value-added), the adjustment of product structure to reduce the value-added ratio. Such as increasing high-density buried / blind-well plates, laminates, the ratio of the IC substrate, integrated component board, rigid - flexible plate and special circuit boards, etc..

Circuit board design pad pore size

Wed, 10 Apr 2013 02:53:58 +0000

Circuit board design pad pore size

[Back]

The circuit board aperture, at least higher than the welding terminal eyelet flange maximum diameter of 0.5mm is required in accordance with the pad to be designed in order to achieve the smallest diameter.

The temperature of the circuit board assembly layout and technology, must in accordance with ANSI/IPC2221 requirements for all nodes test pad. Node is the point of electrical connection between two or more components. A test pad of the circuit board requires a signal name (node signal) the coordinate position of the xy coordinate axis associated with the reference point of the printed circuit board and the test pad (indicating that the test pad in which the circuit board side) need for SMT providing fixtures of data. To promote testability in the circuit. Circuit test fixtures or often referred to as a "bed of nails fixtures assistance. In order to achieve this objective requires:

1 is used to detect the test pad diameter should not be less than 0.9mm

2 space around the pad should be greater than 0.6mm and less than 5 mm if the height of the components is greater than 6.7mm so the test pad should be placed outside the Component 5mm.

Do not place any components or test pad 3 the edge of the circuit board within 3mm.

4 specification probe and a more reliable fixtures. 4 test pad should be placed in the center of a grid 2.5mm hole. If there are possible.

Rely on the edge of the connector pointer pad test. The test probes can be easily damaged gold pointers.

Plated through hole - on both sides of the circuit board Profiler. The tip of the test through the holes on the circuit board, components / welding surface.

Reliability guaranteed PTH / PTV structure is also very important. Circuit board when the size of the hole is less than 1/4 of the basic circuit board thickness, aspect ratio plated through-hole plated through hole plating for manufacturers ability to have an important impact. 0.05mm tolerances should be increased when the borehole diameter of 0.35mm or less, the aspect ratio of 4:1 or greater, the manufacturer should be covered or blocked in order to prevent the entry of solder plated through holes using the appropriate manner. In general, the ratio of the thickness of the circuit board with plated through hole spacing should be less than 5:1.

pcb design problems and improving

Wed, 10 Apr 2013 02:51:23 +0000

pcb design problems and improving

[Back]

pcb design and layout of many limitations. For example, welding technology and equipment required for assembly. Wave soldering, the maximum size of the recess, the distance from the edge and operating space are important factors. The same time, the design must be realized that as much as possible the final waste exactly what it was like, and to try to protect its most sensitive part. For example, any high-voltage circuit should be maintained to prevent and external contacts; circuit board and the components on the pcb item must be carefully placed in order to minimize the damage caused by external objects.
Minimized, in order to achieve maximize production. Consideration should be given to certain restrictions. Also, before you set out to design pcb work, should also take into account the human factor. These factors are described in detail as follows:

Because the etching solution in a small space can not be effective diffusion the PCB wire spacing is less than 0.1mm will not be able to carry out the etching process. Will lead the partial metal can not be etched away.

If the wire width of less than 0.1mm etching process will rupture and damage.

2 pad size than the size of the hole should be at least 0.6mm

The following restrictions listed in board design:

A remake of the original film camera size performance;

2 to watchmaking size of the original;

Minimum or maximum size pcb operation;

4 drilling accuracy;

5 excellent linear etching equipment.

The angle of view from the pcb assembly design. To consider the following parameters:

I.e. minus the pin from the hole MMC MMC resultant difference between the 0.15-0.5mm. And ribbon pin hole diameter is determined according to the maximum material condition (MMC and minimum material condition (LMC. Pcb a support the Component hole diameter should be selected so the nominal diagonal pin and no difference in inner diameter of the support holes will be not more than 0.5 mm and not less than 0.15mm

So that it will not be covered by the larger components.

A reasonable place smaller components.

The 2 solder resist thickness should not exceed 0.05mm

3 screen printed logo can not be used in any pad intersect.

The upper half of the 4pcb bottom half.

Meet the structural symmetry. Asymmetric PCB may become bent.

Need to be considered an important factor that should pay special attention to before soldering, PCB assembly point of view. Tilting may cause short-circuit problem occurs due to pull out the components of its theoretical position. According to experience, the maximum allowance inclination of the component leads should be kept at a 15 angle with the theoretical position. When the diameter of the hole and pin difference is large tilt - up to reach 20 °. Vertical components of the device, pcb inclination up to 25 or 30 ° but this will lead to the decrease of the packing density. FIG. 3-13TO-18-type transistor in the tilt of the type pin package, FIG TO-I8-type transistor device location away from the printed circuit board 2mm aperture Imm inclination of 20 ° can be achieved, of course pin itself is not any inclination.

Of course, the number of PCB assembly usually make the scene as PCB pulled out to replace relatively easy to maintain. The prerequisite for each individual circuit board can exercise its unique functions, the pcb replacement would not have a lot of assembly, to ensure minimal welding / sealing off frequency. Therefore, the design of the PCB must take into account maintainability.

Resolved motherboard circuit board layers

The substrate of the circuit board itself is insulated, not easy to bend the material produced. Appearance can see the fine line information is copper foil <circuit board substrate is insulated, not easy to bend the material produced. The appearance can see the fine line information copper foil. Original foil is covered in the entire circuit board part in the manufacturing process is etching process swaps the left part becomes mesh of fine lines of these lines are referred to as wires or wiring, and is used to provide PCB and parts of the circuit connection. PCB board colors are usually green or brown, solder paint color. The insulating protective layer, can maintain a copper wire, and can also prevent the parts are welded to the not the right place.

The wiring area can be greatly increased. The multilayer spend more single-or double-sided wiring board, the use of multilayer on the motherboard and graphics card. And to put a layer of insulation between each floor board after lamination. Number of layers of the circuit board to represent the layers of a separate wiring layer is usually Floors are even, and includes two outermost layers the rare circuit board is typically a structure of 48 layers. A lot of circuit board layers can be seen by viewing the circuit board aspect. But in fact, no one can board such good eyesight. So, here to teach you a way.

Most of the motherboard and graphics card to use a 4-layer circuit boards, multilayer circuit connection through buried vias and blind hole. Some 68-layer, even a 10-layer circuit board. To see that the board how many layers can be recognized by observing the pilot hole, 4 plywood used on the motherboard and graphics card layer 4 traces, the layers otherwise use (ground and power) with a two-layer board, the pilot hole penetrated board. If any pilot hole in the front of the board, but the opposite can not find, then it must be the same as if the front and back of the circuit board can be found in the pilot hole is 6/8 laminates, naturally it is a 4-layer

In the industry view, 4k TV launched into the warmer period of the LCD panel industry even more powerful; experienced a long period of rock bottom in 2013, is expected to become the panel the industry eagerly looked forward to the "bumper".
The 4k the concept of floor
"TV is mainly to look at, relative to those dazzling intelligence capabilities, I think the quality is more important." TV in a large store, home buyers in Shenzhen, just "80" after Miss Liu 4k TV reflects interest. "It's like a computer or tablet point of view the same video, retina screen display effect is completely different 4k bring experience unprecedented."
When the retina screen concept phone, Tablet PC field of popular, as a showdown with oled technology 4k received extensive attention in the display industry. 4k technology is 4096 × 2160 pixel resolution, which is four times the resolution of high-definition television, belongs to the ultra-high-definition resolution.
Unlike the television industry in recent years into a size and price competition, 4k to bring TV hardware technology upgrade. "The most important feature is the flat-panel TVs attract consumers the quality and functionality; But essentially, the quality should be the first place to consider the elements of the flat-panel TV manufacturers." The the tcl official said, the introduction of 4k TV, will promote industry-wide software and hardware upgrades, and to meet consumer audio-visual experience higher pursuit.
In fact, since the end of 2012, the number of domestic and international brand manufacturers Sharp, Sony, BOE, tcl, Hisense launched 4k TV type. China Securities Journal reporter in the field research the multiple appliances sell ugly discovered "3d", "smarttv" functional concept, consumers are starting to become more pragmatic, quality become important factors that affect their purchase. And since 2013, the brand manufacturers continue to introduce a variety of sizes 4k products, the price is more close to the people. Domestic brands around the 50-inch 4k TV priced in the million or so difference with the high-end high-definition television has not.
Insiders Although less source of the film, but the television industry, the hardware first is normal. Plus other 4k Products such as cameras, projectors launched, some sites launched 4k movie downloads, to 4k TV is widely favored.
Panel industry will welcome Danian
4k injected new vitality for the entire television industry chain. Which LCD panel production enterprises will be the first to benefit. Global LCD panel industry in the second half of 2012 ushered in a time of recession in nearly two years after returning to the warmer.

PCB copper plating chloride ion consumption big reason analysis

Copper sulfate process with the printed circuit board to the development of high-density, high-precision direction proposed more stringent requirements must also control a variety of factors, good copper plating process in order to obtain high quality coatings. The following chloride ions for copper plating process consumes large phenomenon, the analysis of the chloride ion consumption big reason.

1. Appear the chloride ion consume large antecedents: copper plating line Banban surface low current area "dull" phenomenon, the low concentration of chlorine prescription; usually by the addition of hydrochloric acid, the board low current density area coating "dull" phenomenon to disappear, the chloride ion concentration in the bath in order to reach the normal range, board coating bright. If you want to solve the low current density plating "dull" phenomenon by adding a large number of hydrochloric acid, it is not necessarily the chloride ion concentration is too low, you need to analyze the real reason. If you take: to add a large number of hydrochloric acid, may have other consequences, to increase the cost of production, and not conducive to business competition.

Correct analysis of the low current density area coating matte "Cause: by adding a large amount of hydrochloric acid to remove the coating is not of the low current density area bright" phenomenon, and the case of chloride ions is too small, only need to add the hydrochloric acid to increase the chloride ion concentration reach the normal range, the low current density area bright coating. If you want to add exponentially to the hydrochloric acid so that the concentration of chloride ions to reach the normal range? What is to consume a large amount of chloride ions it? Chloride ion concentration is too high will brightener consumption fast. Chloride ion and brightener will produce the reaction, the excess of chlorine ions will consume; Conversely, an excess of brightener consumption of chloride ion. Because too few chloride ions and brightener overdose are causing the main reason for the low current density area plating bright ", and therefore visible, resulting in" copper plating chloride ion consume large main reason brightener concentration is too high.

Domestic LCD panel intends to again increase import tariffs

Mon, 01 Apr 2013 10:12:26 +0000

China resumed on April 1 last year, the tv panel import tariffs to 5%, the Chinese media reported that Chinese home appliance brand manufacturers Konka competent and released the tv panel import tariffs may also increase 3 to 5 percent of the message, thissaid Zhang Xiaobiao, witsview general manager, not heard;, but Zhang Xiaobiao speculated that if the adjustment of tariffs, may be linked with a new wave of energy subsidies for.
But also because of the uncertainties of China's new wave of energy subsidies in recent national power plant to Taiwan panel procurement become more conservative, the holiday market expectations Distribution tide may come to nothing, because the warmed shipped in March compared to February, 4 month seems purchases will lower panel factory the tv panel production but still put the pedal to the metal, Zhang Xiaobiao said, when the new wave of subsidies for energy-saving measures, baked procurement even if the recovery of the national plant, but the panel plant in the hands of the huge inventory may panel prices to lack of motivation, not accidentally.
As to whether China might again raise the tv import tariffs? Zhang Xiaobiao think, if so, is likely to be linked with subsidies After all, the Chinese panel makers 8th generation line capacity, but can supply tv panel size is limited, the amount is not enough improve tv import tariffs measure whether, in addition to protect domestic industry panel makers should also consider the needs of the brand factory in China.
China's 12th Five set a target of "economic stability", "expanding domestic demand", judged to China next bound also to re-introduce a new wave of energy conservation subsidy policies, but also in the "structural adjustment", that is to say, the subsidies will be different from the past, the threshold will be higher, more stringent, not enough to supply the technical capabilities of the current panel factory in China, was finally to Taiwan, South Korea and even Japan procurement panel.
In, Zhang Xiaobiao judged that if China this year will once again increase the tariff should not be comprehensive, with energy subsidies selective increase account, on the one hand, the domestic panel makers, on the other hand can meet the demand for brand factory .

How to split settings PCB with the inner layer of the middle layer of the multilayer circuit board

Thu, 28 Mar 2013 03:59:02 +0000

How to split settings with the inner layer of the middle layer of the multilayer circuit board

The multilayer circuit board and the circuit board in general different from that the multilayer circuit board in addition to the top and bottom, there are several intermediate layers, these intermediate layers may be the signal layer (mid layer), can also be internal power / ground layer (internal plane).

An intermediate layer, multi-layer circuit board created and set

The intermediate layer and the top underlying similar kind, just can not place the component. The internal power / ground layer is a layer of copper film layer, may be divided into mutually isolated regions, each region a copper film with a lot of power / ground network through the pad or through-hole Unicom, its role is to simplify the power supply and the bottom connection to the grid, to reduce the line impedance, enhanced anti-interference ability of the power supply network.

Create method of the intermediate layer, can be set by a special layer management tools ---- layer stack manager (layer stack manager) to achieve specific operation to select the menu command [design] / [layer stack manager], in the pop-up dialogue The box can be convenient settings need layer. Four panels, for example, the setting of the two intermediate layers respectively, the power supply layer (power shown) and ground layer (gnd), the connected network number is not set. It is worth noting that for the four panels, the general way of the choice of layer signal layer, power supply layer, the formation, the signal layer. The better choices layer signal layer, power supply layer, the signal layer, stratum.

2, the segmentation method of the inner layer in the multilayer circuit board

Planning and set up of the intermediate layer, component placement is completed, the segmentation of the inner layer can protel dxp 2004 split of the inner layer is simpler and much more convenient than the previous version. Specific methods of operation, select the menu command [design] / [the pcb level color] or shortcut letter key l, can be transferred to the [board layer and color】 panel, so you can turn off unneeded layers (top, bottom , other intermediate layers) to display the desired separation layer, for example, a power supply layer of the power supply layer of [power] tick "power" display on the PCB interface layer. Back to the pcb operating interface, select the menu command [placed] / [Linear] or shortcuts p / l, bring up the line drawing tools, selected to split power pad (vcc) to form a closed surface, double-closed box, pop-up dialog box, select the split out of the closed area are connected to the network (vcc). A partition good inner layer has been completed, the other of the power supply network (VDD) of the operation is similar.

How to solve the thermal reliability of the circuit board

Thu, 28 Mar 2013 03:54:26 +0000

How to solve the thermal reliability of the circuit board

Under normal circumstances, the copper foil on the line Banban distribution is very complicated, difficult to accurately modeled. Therefore, the modeling need to simplify the shape of the wiring, try to make a simplified modeling with the ANSYS model line Banban the actual line Banban close the electronic components can also be applied to simulate, such as MOS, the circuit block.

1 Thermal Analysis

Thermal analysis can help designers to determine the electrical properties of the components of the circuit board, to help designers to determine whether the element or line Banban because of the high temperature and burn. The simple thermal analysis just calculating the average temperature of the circuit board, the complex will have an electronic apparatus comprising a plurality of line Banban create a transient model. The accuracy of the thermal analysis ultimately depends on the accuracy of the power consumption of components in the circuit board designers.

Weight and physical size is very important in many applications, if the components of the actual power consumption is very small, it may lead to the design of high safety factor, so that the circuit board design uses as power consumption values with the actual inconsistent or too conservative element according Thermal analysis was performed. Contrast (as well as more serious) thermal safety factor is too low, and that component is actually running temperature than analysts forecast to such questions are generally on the circuit board through the installation of a heat sink or fan cooling. These external accessories increase the cost, and extended manufacturing time, adding a fan in the design but also to the reliability factors of instability, the main line Banban active rather than a passive cooling method (such as natural convection, conduction and radiation cooling).

Line Banban simplify modeling

Before modeling analysis line Banban main heating device which, if the MOS transistor and the circuit block, etc., these elements at work, most of the power loss converted to heat. Therefore, modeling mainly need to consider these devices. Also, consider the circuit board on the substrate, as the wire coated foil. They play the role of conductivity in the design is not only, but also play the role of the heat conduction, the thermal conductivity and heat transfer area larger than the line Banban electronic circuit is not an integral part of its structure by the epoxy substrate and as wire coated foil. The epoxy resin substrate having a thickness of 4 mm, a copper foil having a thickness of 0.1 mm. The thermal conductivity of the copper was 400W / (m ° C), while the thermal conductivity of the epoxy resin is only 0.276W / (m ° C). Added copper foil is thin and fine, but then the heat strong guiding role, and therefore can not be ignored in the modeling.

Double-sided PCB circuit layout and system testing

Thu, 28 Mar 2013 03:50:53 +0000

Double-sided PCB circuit layout and system testing

The basic principle of the high-speed circuit-sided circuit board layout as follows: ① consider the parameters of the distribution of the circuit components in the high-frequency operating conditions, all components should be double-sided circuit boards

On the uniform, neatly arranged compact, minimize and shorten the length of the lead between the various components. ② analog circuits and digital circuits are separated. Eliminate the interference of digital signals to analog signals easily. ③ of reasonable arrangements clock circuit position.

Can not clock circuitry and signal lines directly connected, placed in the center of the double-sided circuit board and ground. Optical burst module circuit layout can be considered from the following four aspects: ① the laser MAX3656 and connector position set in advance specification of the SFMSA., The laser and drive as close as possible. ② limiting amplifier MAX3747 a position as far as possible and the rear end of the main amplifier chip MAX3748 close to guarantee the correct reception of the signal trend and the amplified signal, and the maximum degree of reduction of interference. ③ clock and data recovery circuit The MAX3872 should be placed in a central location and reliable grounding. ④ MAX3654-47 ~ 870MHz Analog CATV Transimpedance Amplifier merge process can be considered as functional modules.

First, the expansion of the package components library to meet the needs of the placement and routing design; then, the use of relevant software directly call components encapsulated symbol, to complete the initial circuit layout wiring design. After initially identified in most of the components layout, usually also wiring pre-and post-route simulation analysis. Pre-layout simulation analysis is to determine the length of the key signal traces, impedance matching and whether repeated adjustments, combined with the delay, reflection and noise impact signal integrity simulation analysis, from the perspective of the system as much as possible to ensure that signal integrity, the relative delay of the input signal can not be more than 0.2ns.

EMI design of high-speed double-sided circuit board design must comply with the design requirements of the EMC. To measure the system EMC design quality, it must first be precise EMI testing. Testing should be based on the frequency domain to use on the basis of measuring instruments, test methods should strictly comply with the various types of standards. Spectrum analyzer as the test equipment, components of the entire module on the full range of three-dimensional test can show the overall condition of the electromagnetic radiation. Processed into a printed circuit board according to the design dimensions, a patch and a welding assembly, circuit board EMI debugging; small encapsulation shell fitted into the optical module of the circuit board; last light module testing.

The switching printed circuit board assembly time and particularity

Thu, 28 Mar 2013 03:49:00 +0000

The switching PCB assembly time and particularity

Assembly of electronic products because of its large number of components, a wide variety of electronic product life cycle is short, to the production operation scheduling brings huge challenges, more variety, small-volume, variable volume has become a mainstream mode of production of electronics manufacturing . In this mode, the switching time between the many varieties occupy an increasingly large proportion of the entire assembly time.

By high-speed Mounter and multifunction placement machine. In fact, the entire PCB assembly line also includes the delivery board machines, screen printers, dispensers, reflow and curing oven, closing plate machines and other equipment, these devices linked together to form PCB assembly lines, but these auxiliary equipment and does not constitute a bottleneck of the whole pipeline processes, and thus be omitted in the modeling. Each placement machine can accommodate the feed trough 20 bits, each element occupies a feed trough bit Mounter. In general, single varieties PCB number of types of components does not exceed the capacity of the feeder, but the the many varieties PCB required total number of component types are usually beyond the capacity of the feeder.

The placement process different varieties of PCB components need to be placed in the feed trough, mount to the specified location on the PCB take stickers device to remove the components from the feed trough. According to the survey data on the empirical study, the time to the average mount a component of the high-speed Mounter 0.06s, the average switching time of a feed trough for 180s. Multifunction placement machine with two tables, but only a workbench, a workbench for placing large or profiled element, each station to accommodate 10 of the feed trough, the average mount a component requires 0.18s The average time to switch to a feeder 220s. When switching between different varieties of PCB, SMT switch requires some preparation time, usually for about six times the trough time to switch to a different component, that is, the 1200s. This shows that the switching time plays a decisive role in the electronics assembly process.

Variety of small quantities environment, usually grouped on the PCB will have similar characteristics PCB grouped this way, in the same group, different varieties of the PCB assembly do not need to replace the feeder does not need switching time; when two groups between the PCB needs to be replaced when the feeder is necessary to consider the switching time between them. According to the PCB production scheduling problem is divided into two levels: the first level of the scheduling problem called "board-level" scheduling problems, that is, to determine the order of production within the PCB in a PCB group; scheduling problem, said of the second-level group level scheduling problem, that determine the PCB tissue between the production order.

Peelable modern printed circuit board

Thu, 28 Mar 2013 03:44:11 +0000

Peelable modern printed circuit board

Abstract: This article uses a peelable glue instead of a dedicated tape as the gilded and HASL usual protection layer skiving process.

Keywords: Peelable mask porosity

I. Introduction

Pin gold-plated and hot air leveling two important processes in the printed circuit board production, without the processing part to be protected. The used dedicated tape as the protective layer of the plating and HASL usually, but this method is the high cost and long production cycle (mass) is often more than adhesive residue affect the appearance of the plate surface, and other shortcomings. Some enterprises in the coastal peelable glue instead of tape has been used, it has a special tape gold-plated and hot air leveling protective effect. And peelable glue also has the following advantages: greatly reduce the cost, simple operation, no residual traces and stains, easy to mass production. The costs have been placed in a very important position, reduce costs of each printed circuit board unemployed for everyone concerned, peelable glue bound application prospects I plant some exchanges have launched.

Peelable glue some of the features

Peelable adhesive is a one-component screen printing protective ink, 100% solids content, the color blue viscous liquid. The protection of a protective layer part of the plating process line and a solder lead can be used as an on-plating. Peelable glue instead of tape as a protective layer. Because it is a temporary coating, so at the end is completely peeled.

Third, the process

Use Peelable process flow:

Fourth, the operating points

These in order to make peeling easy, before coating to the printed boards cleaned, the removal of grease and stains. When cleaning, use a special cleaning agent.

Peelable adhesive there is a certain viscosity of the viscous liquid, a coating is generally used method of serigraphy. Used when operating below 18T mesh, and 60 degrees of the fillet polyurethane scraper, in order to ensure the peelable plastic has a certain thickness, so as to facilitate peeling.

Coating generally does not use any diluent, and have a certain thickness in order to make the gum, the requirements in the coating when the blade angle of attack of 45-55 degrees. In order to guarantee one percent aperture ratio, feed rate slower than usual, or else serve to protect the role.

Coated most to achieve the following results: the board peelable glue evenly, but also have a certain thickness; hole of the plastic flows into the two-thirds to one-third of the hole depth, printed on the first side, can not remember flows into the other surface to form a "rivet". Otherwise cause difficult to peel.

The degree of drying curing is also a great impact on the peel, generally 140 ℃ ,20-30 minutes in a hot air circulation oven curing, after curing peelable glue should have high internal stress and elastic. Curing excessive and insufficient curing, are not optimum peeling effect.

V. Conclusion

By several tests, we found that the the Peelable performance very stable, with solder mask layer adhesion. For stripping difficult problem by changing the screen printing method, for different mesh screen use different hardness scraper, to adjust the curing time, played a very good role, the stripping effect has been improved.

Pin gilded peelable glue can be, no part of the protective effect of the hole and do not need plating gold plating liquid penetration; another hot air leveling process to protect the gold-plated pins part no skiving off at high temperatures , as well as tin-lead gold feet stick to the visible peelable glue can withstand high temperatures.

Peelable phase for special protective tape costs greatly reduced, as well as its good performance, its application is quite extensive.

The indoor LED dot matrix display characteristics and scan driver PCB

Thu, 28 Mar 2013 03:02:24 +0000

The combination LED dot matrix display appeared since the 1980s, the light-emitting diode pixel, high-brightness light-emitting diode core array of combinations, epoxy resin and plastic molded packages from. With high brightness, low power consumption, small pin, large viewing angle, long life, humidity, heat and cold, corrosion resistance and other characteristics.
Dot-matrix display both monochrome and two-color, red, yellow, green, orange. LED dot matrix; according to the number of pixels is divided into 4 × 4,4 × 8,5 × 7,5 × 8, 8 × 8,16 × 16,24 × 24,40 × 40 and other dual color three primary colors, etc., according to the color of the different pixel color display of text, images and other content, single color dot matrix can only be fixed colors such as red, green, yellow and other monochrome, two-color and three-color dot matrix display The color of the content is determined by the pixel color LED lights combinations, such as red and green light shows yellow, if to control diode lighting time in accordance with the pulse mode, you can achieve 256 or more high-level grayscale display, you can achieve true color display.Several internal LED dot matrix display circuit structure and form factor, other models of lattice structure with pin test access to, use of LED dot matrix display single block, either in place of the digital display digital display each kinds of Chinese and Western text and symbols. 5 x 7 dot matrix display is used to show the Western alphabet. 5 x 8 dot matrix display is used to display the Western text, 8 x 8 dot matrix is used to display the Chinese word can also be used for graphic display. Multiple dot matrix display combination can constitute a large-screen monitor, but such practical devices often driven by the microprocessor or microcontroller control.LED dot matrix scanning driver programSeen by the internal structure of the LED dot matrix display, the device should adopt the dynamic scan driver to work, because most high-brightness LED die, a row or a column monomer LED drive current choice of narrow pulses, but the average current should be limited at 20mA. The monomers most dot matrix display LED forward voltage drop of about 2V or so. But the major highlight ∮ 10 dot matrix display the monomer LED's forward voltage drop of about 6V.The large-screen display system is generally composed by a plurality of LED dot matrix module to a combination of building-block approach, each of the small modules have their own separate control system, combined as long as the introduction of a total controller controls module command and data, this method is both simple and easy to show, easy maintenance. Pixels between the implementation of the point-to-point control from the driver IC output pin called a static driver from the driver IC output pin to between pixels called "point of the column control scan driver, he needs to line control circuit : from the driver board can clearly be seen: static drive does not require line control circuit, the cost to teach high, but the display is good, good stability, loss of brightness teach small; scanning drive it needs to line control circuit, but low cost , display brightness loss teach large. Lit in the display area, while the number of rows in proportion to the number of rows and the region as a whole, said the scan mode; indoor single-color is generally 1/16 scan, indoor full color is generally 1/8 scan, Outdoor single color is 1/4 scan, outdoor full color generally static scan. LED display driver market static scan and dynamic scan two, the static scanning is divided into static real pixel and static virtual, dynamic scanning is also divided into dynamic real image and dynamic virtual; drive the device generally used domestically the HC595, Taiwan MBI5026 Japan's Toshiba TB62726, general sweeping 1/2, 1/4 sweep, 1/8 sweep, 1/16 sweep. For column descriptions: a full color module pixels 16 * 8 (2R1G1B) MBI5026 drive module using a total of: 16 * 8 * (2 +1 +1) = 512, MBI5026 16 chip, 512/16 = 32 (1) with 32 MBI5026 chips, static virtual (2) 16 MBI5026 chip, 1/2 sweep dynamic virtual (3) 8 MBI5026 chip is dynamic / the 4 sweep Virtual board two red lights in series (4) 24 MBI5026 chip, static real pixel. (5) with a 12 MBI5026 chip, is dynamic and 1/2 to sweep the actual pixel (6) 6 MBI5026 chip dynamic 1/4 the sweep RealPixel in LED display, scan mode, 1/16, 1/8, 1/4, 1/2, static. If different? The easiest way is to count the the cell plate number of the LED and 74HC595 number. Calculation methods: LED number divided by the the 74HC595 number divided by 8 = fraction of scanning the actual pixel corresponding virtual: In simple terms, the actual pixel screen is red, green and blue three light-emitting tube constituting the display Each of a light emitting tube ultimately participate only in a pixel imaging use, in order to obtain a sufficient luminance. The virtual pixels are controlled using a software algorithm of each color light emitting tube which ultimately participate in a plurality of adjacent pixels of the imaging, so that with fewer lamps to achieve greater resolution, enabling the display resolution fourfold increase.Static and dynamic display two of each module display LED dot matrix display system.

LED has the advantages of energy saving, environmental protection, is the backbone of the city lighting engineering. The principle of the LED technology are some semiconductor materials will be issued in the case of current pass to the particular wavelength of light, this electrical to optical conversion efficiency is very high, of the materials used for different chemical treatment, can be obtained various brightness and the perspective LEDs. It is a means to control the semiconductor light-emitting diode display screen used to display text, graphics, images, animation, quotes, video, video signal. The following is the LED display common signal and explanation of the concept.1, the data signal: means for providing the required data of the display image. There must be a clock signal coordinate data can be transmitted to the display point. Usually in the display data signal are separated, if a data signal short positive or negative, then the corresponding color will appear bright light, when the data signal is interrupted, the corresponding color display is uncertain.Signal: ABCD ABCD line row select signal, only the dynamic scanning display only exist. The ABCD is actually a binary number, A is the least significant bit, if the binary representation ABCD signal controls the maximum range is a 16-line (1111). The AB signal representation are four lines (11), so as long as the AB signal when the 1/4 scan can. When the line control signal abnormal, the LED display will appear misplaced, of highlighting or images overlap phenomenon.3, STB latch signal: STB (LT) for the latch signal, the effect is the data in the shift register to the latch, and its data content via the drive circuit lit LED display. Latch signal is also need the clock signal coordination in order to display a complete image. In any case, when the latch signal abnormality causes the LED display the entire board display disorganized.4, EN enable signal: EN energy, N to ground (GND) to confirm the same interface unit board and control card, can be connected directly. If not, you need to create their own conversion cable (to switch the order of the line). Control signals, the brightness of the entire screen can also be used to display blanking. As long as the adjustment of its duty cycle changes of the luminance can be controlled. When the enable signal is abnormal, the whole picture appears bright, dark or bright smearing.5, the LED display CLK clock signals: CLK (CK) to the clock signal, a shift pulse is supplied to the shift register, each pulse causes the data entering or leaving a place. The data port on the data must be coordinated with the clock signal in order to normal transmission of data, the frequency of the data signal must be 1/2 times the frequency of the clock signal. In any case, when the clock signal abnormalities cause the LED display the entire board display disorganized.

Our hybrid integrated circuits into the innovative phase

Tue, 26 Mar 2013 07:36:52 +0000

Recently, the State Council issued the "12th Five-Year" national strategic emerging industry development plan "(hereinafter referred to as the" Plan "), the high-performance integrated circuits works as one of the 20 major projects. China's IC industry competitive in the global market is weak, the high degree of external dependence. 2010 China's IC imports amounted to 156.99 billion U.S. dollars, a record high. Integrated circuit has two consecutive years, more than crude oil imports of the largest commodity. "Plan" clearly the future state will focus on supporting the policy, and strive to 2015, the proportion of IC design industry output value of the domestic market increased by 5% to 15%. "Planning" also new flat panel display works included in the development plan. In recent years, the flat panel display industry has shown a trend of rapid development. In terms of technology, will be the focus tft-lcd, pdp auxiliary, amoled for the future development direction. In 2010, the global flat panel display industry scale is about $ 90 billion, of which 86.4% tft-lcd. Displaysearch forecast, tft-lcd output value for 2015 is expected to be more than 130 billion U.S. dollars, accounting for 91% of the entire flat panel display industry. 1
High-performance integrated circuit engineering:
Last year, the output value of the IC design industry's first ultra-$ 10 billion
Since 2000, China's IC industry high-speed development. By the end of 2010, the IC industry sales have reached 144.015 billion yuan, China has become one of the fastest growing region in the same period in the world's integrated circuit industry development. The scale of China's IC industry world IC industry by the end of the "15" is less than the total size of 4.5% to 8.6% in 2010. In 2011, the output value of China's IC design industry for the first time more than 10 billion U.S. dollars, accounting for the global design industry accounted for 13.89%. Productivity improvement faster, but the mainstream products did not enter the the international main battlefield, the enterprise overall strength is still weak.
Gap with foreign giants
"China's high-performance integrated circuit industry is still in the stage to catch up with the advanced technology from abroad." CIC Securities analyst Li Chao told reporters that: "From the high-performance integrated circuits for the whole industry chain, is divided into four main design aspects of the upstream industry and the manufacturing sector, industrial downstream packaging and testing session from now, we in the strength of manufacturing in this area is still very weak, we have developed a pretty good design, now there are a lot of small companies in engaged in related design work, as well as part of the company outside the market, but overall, we are still some gaps with foreign giants, not in the same breath. "
Electronic components from a brokerage analyst agrees, he told reporters that China's domestic engaged in high-performance integrated circuit industry, "manufacturing" part of the business of the larger company mainly Shanghai Hua Hong nec and SMIC SMIC still continue to do the development, but the Shanghai Huahong nec been declining. Intel, Samsung and Taiwan's electromechanical, UMC and ASE are regarded as the international giants of the industry, that is, state-of-the-art technology and production capacity of the industry, are currently in foreign countries and Taiwan in the hands of our development status now can not be compared with them. "
The double demand driven development
Insiders pointed out that the planning highlights the country to develop confidence in the integrated circuit industry. China's IC industry competitive in the global market weak, a higher degree of external dependence, the Chinese government is actively encouraging the development of the domestic IC industry chain. Double the demand of the national strategy and economic development, will become an important boost power driven industries are rapidly upward development.
Li Chao told reporters: "a wide range of high-performance integrated circuit technology applications to use in our daily lives, mobile phones, computers, large aerospace defense industry, are able to find its" shadow "in the electronics industry, just as iron and steel industry to industry, belongs to the very foundation of the industry.

Flash chip contract price fell by 30%

Tue, 26 Mar 2013 07:33:49 +0000

Continue to negotiate after the past two months, after consultation, the majority of buyers and sellers of nandflash industry by the end of July, and finally the majority nandflash chip contract price reached broad consensus. June to July, during the time when the memory card and ufd path of market and system products oem customers the traditional off-season, coupled with the effect on 2q quarter bottom, downstream customers multiple priority busy to go hand excess inventory, they are in this the period covering inventory will also not be too high. Part nandflash chip past two months, the cumulative decline in the contract price of about 4-30%, but if the sub-4 view of the past two months, the average in each phase of decline, it still falls off-season reasonable price declines interval within, although the buyers and sellers still little differences, but also are more able to accept this compromise bargaining program.
Looking nandflash market outlook, previous industry concern of a lot of overall environmental uncertain variables may weaken 2h11 peak season demand recovery of force Road, but recently Europe and the United States delayed a long time the Finance controversial impasse has exposed the dawn of a turnaround, Europe and North America by many years of accumulation of Finance Shen ills complicated by the financial tsunami so far still resonates today, although the parties of prescription Countermeasures For solution of livelihoods hung upside suffered some differences, but fortunately several times under the communication of regional politicians in Europe and the United States to discuss and reconcile Ding Nai parties have achieving the same consensus attainable, and believe that all parties are happy to see the Finance impasse alleviate the, 2h11 global economic recovery walking can be continued to the point on the smooth road. The expected traditional 2h the season nandflash inventory restocking demand is expected in customer inventory drawdown, at the end of August will be some system products oem large customers began to drive, when the price is also expected to appear bottomed. Although the the 3q11 peak season effect will be deferred to September began to return to temperature, but expected 4q11nandflash terminal applications listed effects of new products, will be expected to become the main driving force to enhance the year-end sales season to make up for the memory card and ufd pathway Market relatively weak demand, can partially to absorb nandflash supplier 4q11 from 2xnm new process and new capacity new volume of output, because most of the downstream customers to grasp the degree of subsequent market demand is not yet clear follow-up on the strength of the force nandflash price support needed depending on 4q11 actual market

The factor on the composition of PCB Price

Wed, 20 Mar 2013 10:04:37 +0000

On the composition of PCB Price
Published :2013-3-16

Over the years, PCB prices varied by people outside the industry are familiar with, even if some years of PCB experience in personnel since not all understand there is a world of the ins and outs of the following to analyze the main factors affecting the price of pcb:

Cause the price of diversity, PCB materials used different
For example, an ordinary double sided sheet generally fr-4, cem-3, etc., thickness from 0.2mm to 5.0mm range copper thickness from 0.5oz to 3oz all sheet a cause a huge price difference; solder resist ink, ordinary thermosetting oil and the the photosensitive Green oil also there is a certain price difference, and therefore the material caused by different price diversity.

PCB production process caused by different price diversity
Different production processes will result in different costs. Gilded board with spray tin plate, making the shape of the board of gongs (milling) and beer (red) plates, screen printing lines with dry film line will form different costs, lead to diversity prices.

Third, the PCB itself difficulty caused prices Diversity
Even if the material is the same, the same technology, but the PCB itself difficulty will result in different costs. Such as two circuit board has 1000 holes, the pore size of the one plate are greater than 0.6mm with another plate pore size of less than 0.6mm will form different drilling costs; such as two circuit boards are other same, but linewidth different line from A are greater than 0.2mm, the one kind are less than 0.2mm, will also result in a different production costs, because of the difficulty plate higher scrap rate, inevitably increase the cost, and thus cause the price of diversity.

Customer requirements will cause the price of different
Customer requirements will directly affect the yield of the mill, such as a board ipc-a-600e class1 require a 98% pass rate, but may be only 90% pass rate class3 requirements, resulting in the different cost MILL product prices, leading to ever-changing.

PCB manufacturers prices caused by the diversity of different
Different because of the different manufacturers of process equipment, technical level, even if the same product, but also a different cost, nowadays many manufacturers prefer to produce spray tin plate, because the process is simple, low cost, but also part of the manufacturers of the gold plate, the scrap rate , resulting in higher costs, so they prefer to produce spray tin plate, thus they HASL offer lower rather than gilded plate.

Payment method price difference caused by different
PCB mill usually different ways of payment adjustment PCB price ranges from 5% to 10% range, thus causing the price differences.

Seven regional differences cause the price of diversity
Domestic geographically speaking, from south to north, the price was increasing trend, different regional price differences, and thus different regions also contributed to the diversity of the price.

The first nine months of 2012 washing machine market in China is analyzed PCB

Wed, 20 Mar 2013 06:36:39 +0000

In 2012, the domestic economic growth rate is slowing, as the national policy of stimulating domestic demand in the maturing and the continuation of the housing purchase restrictions, and domestic washing machine market entered the adjustment period. In the third quarter of 2012 has passed, the washing machine is still at the low end market, yi kang is calculated, according to data in the 1 ~ 9 months, total retail sales of 21.99 million units, washing machine market 11.6% year-on-year drop in retail sales amounted to 36.4 billion yuan, down 8.2%.

Although off to a bad start, but began in June 2012 appliances energy-saving subsidies or brought hope for industry bottomed out, 1 ~ 9 months, washing machine market decline significantly narrowed, retail sales year-on-year growth from January to September narrowed to 27.3% - 6.4%, increased by 20.9%, year-on-year growth in retail sales from January to September narrowed to 26.8% - 0.5%, increased by 26.3%.

Washing machine market in 2012 is "low", but the market is, there are bright spots, still can see vigor in trouble - platen washing machine and although growth is slowing, but year-on-year growth is still better than single cylinder and double and three types of BoLun washing machine barrel; The large capacity washing machine is more and more popular with consumers; Frequency conversion technology has been applied by conduction to the BoLun platen washing machine washing machine; Accelerates the development of online market.

The main platen washing machine is driven by the market

Yi kang in retail monitoring data show that from January to September 2012, the whole washing machine sales fell 14.1% year on year, the weak market, among them, the platen washing machine sales fell 9.7% year on year, lower than the overall market decline rate. BoLun washer fell by 13.1%, basic synchronization with the overall market performance. While single cylinder washing machine, double barrel fell sharply, did fall by around 20%, well above the level of the market as a whole, these two kinds of washing machine market share together accounted for about 15% of the overall market, market share is being squeezed from further. Be worth what carry is, after several years of market popularization, platen washing machine before continued the momentum of development, in 2012, is still in the washing machine industry's major manufacturers vying for the important segment of the market. Yi kang in monitoring, according to data from January to September 2012, platen washing machine account for the overall market sales accounted for 25.4%, to 46.0% of the total retail sales, retail sales, retail sales market share than the same period in 2011 increased by 1.0 and 1.8% respectively.

The large capacity washing machine popular market

With the change of the laundry habits of Chinese consumers, the clothes on the weekend washing phenomenon more and more common, the large capacity washing machine began to popular market. Yi kang in monitoring, according to data from January 2012 to September, more than 7 kg and large capacity washing machine segment BoLun retail sales market share of 23.0%, 17.0% than the same period in 2011 increased by 6.0%, among them, the period of product, the biggest increase in 7 kg capacity increased by 3.2%; More than 7 kg and high-capacity platen washing machine retail sales 25.9% from January to September 2011, to 36.0% from January to September 2012, rose by 10.0%, 7 kg capacity products rose 8.7%. Thus, the large capacity washing machine is more and more popular among consumers, the market prospect is bright.

From the drum to BoLun transfer frequency conversion technology

"Frequency conversion" technology application in air conditioning manufacturing early, then washing machine production enterprise also began to adopt frequency conversion technology. To seize the washer upgrading opportunities, production companies adjust strategy, upgrade application of frequency conversion technology. After the platen washing machine, in recent years, high-end BoLun washing machine manufacturing in frequency conversion step by step, also the mainstream manufacturers are increasing frequency conversion products marketing.

From January to September 2012, frequency conversion washing machine market fell 8.0% year on year, significantly better than the whole washing machine market 14.1% of the decline in speed.

Washing machine market competition is the driving force of industry forward to upgrade PCB

Wed, 20 Mar 2013 06:34:44 +0000

Always up and down, it resolutely applied in home appliance market. Washing machine market, as you know, after a few years ago after the explosion, started to enter the industry of winter nearly two years, big market is depressed, it is mainly affected by the influence of the external environment, such as the housing slump and industry policy. So, low in this industry, enterprises want to break, have to rely on technology, industry want to out of the woods, competition will be inevitable.

A weak, big market, industry transition into the adjustment

Adjust - industry status quo thinking

In September 2012, released 2012 annual white paper on China's washing machine market, the data show that in July 1, 2012, cumulative sales of nearly 11.49 million washing machines, domestic city market was down 23.89%, sales of about 25.7 billion yuan, has fallen by 20.72%, compared to the same quantity for both lower. Investigate due to market a few years ago by the national "cash-for-clunkers", "home appliances to the countryside" policy of stimulating domestic demand stimulus, part of the market demand in advance, to this year, the policy of stimulating role in weakening, and also to have ended, and the property market downturn, big market presented the weakness of poor posture.

HCR (the study) that, in such a situation, the adjustment is necessary, it is thinking about the present situation of industry, is the industry of the future exploration. Stay long on the national policy support for home appliance companies, must adjust the structure of resources and industrial line, look for breakthrough development.

Transition - companies forward way

In market adjustment, transformation and upgrading to become the main melody, is also enterprise go on the way out. In recent years, as people living standard rise, the consumer experience is more and more important, therefore, based on user requirements for product features and technology innovation promotion has become the developing direction of the enterprise in the future, enterprises not only to keep up with the pace of consumer demand to upgrade technical innovation, and constantly to new products and new marketing policies to guide consumer renew ideas.

Second, constantly upgrade of industrial structure, large capacity ChengXinChong products

Adjust transition of washing machine in the market, constantly upgrade of industrial structure. Mainly embodied in the following aspects:

First, high-end products popular, accepted by the public. Platen washing machine for a long time, has been in the market has a premium image, its high XiJingDu, low wear, water-saving energy-saving, environmental protection health advantage, make it be the first choice of the people to buy a washing machine, but the high price is that many consumers away. After recent years of development, at present, the data show that 1, 2012 - July, growth is very obvious, platen washing machine sales accounted for more than 30%. At the same time, we also see, platen washing machine prices have edged up, this shows fully convincingly that high-end washing machine is more and more accepted by the public. In addition, 5000 yuan or more high-end multifunctional washing machine also is a hot market.

Second, the large capacity ChengXinChong products. This is also the necessity of developing the market. In recent years, as people life rhythm speeding up, centralized laundry is very unusual, so big volume has become people to upgrade a large factor. Data shows, for three consecutive years, retail sales accounted for more than 6 kg and volume section of the washing machine market is higher than walk step by step, so far, market share has exceeded 60%, become the market main body; Especially in the high-end drum washing machine market, the trend is more apparent, as of July 2012, more than 7 kg drum washing machine market share of 30%.

In conclusion, HCR (the study) that adjust the transformation of industrial structure upgrade for granted, adapt to market development. Only cling to the consumer market demand, constantly improving product experience, can get better development.

Third, the breakthrough tradition, online market began to loom

With the increasingly development of Internet and mature, the network channels of the low cost advantage is gradually obvious, more and more enterprises begin to break through the traditional home appliance sales channel, gradually set up their own online counter. Especially in this year, electric ShangShiChang active, price war, electrical business giants 815 and "double a" feast for electricity, which makes the online market began to loom, influence greatly ascend.

Data shows, at present, the washing machine online sales account for the overall market share has reached more than 10%, has a great potential for development. In addition, the product structure, of online sales market mainly in small small single cylinder, double cylinder, and the number of kg BoLun washing machine is given priority to, high-end drum washing machine of minimum, less than 10%. Mainly because the consumers' online purchase large kg high-end products too much concerns, as these products price is high, if quality problems do, ke is broken in transport bad also, enterprise's sincerity management degree and how these factors, also may be out of business for these product shop goods, etc.

Fourth, technology and competition, industry developing hybrid

Technology: the power of the enterprise restructuring

Market entered the adjustment period, means that the industry must get rid of the previous scale and spell spell prices of means of competition, and to rely on competing products technology content and technological innovation, it also will further adjust products structure, technology innovation to create the market demand for consumption increment, has become a corporate restructuring of a big power.

In this era of technology strives for the survival, the high quality of life concept relative permeability contributed to the gradual improvement of the consumer demand for washing machine functions, the new consumption hot spots are conveniently formed - aseptic water-saving energy-saving, green environmental protection, health, intelligence and so on.

Frequency conversion washing machine, with its water saving and energy saving, mute, such characteristics as high abluent, win the hearts of the public. Data show that the frequency conversion washing machine market accounted for 12% of overall retail sales market, is up nearly 8% in 2009, trend is obvious.

Anti-bacterial function, health awareness. This is mainly due to people life quality rise, the attention to health promotion. And with the last September for household and similar electrical antibacterial, antibacterial, purifying function to the special requirements of washing machine, the formal implementation, deepened people's trust in the antibacterial function, are willing to pay more money for this function. At present, each enterprise on the market of aseptic different features, like samsung's unique silver ion disinfection, panasonic's light silver anti-bacterial wash, sanyo, lg nanometer antibacterial and steam electrolysis of water in addition to bacteria and ozone o3 in addition to bacteria, etc., has been widely accepted by people. Therefore, consumer demand for enterprise opportunity, technology and create value for enterprises, is the driving force of enterprise transformation promotion.

The driving force of competition: forward upgrade

Competition is everywhere, in the home appliance market. After rapid development for many years, the washing machine market, the competitive landscape in the last two years has become relatively stable, but each brand competition between enterprises is increasingly fierce. Is just because of the existence of competition in the industry, however, didn't even have a sense of crisis, prompted the enterprise oppressive feeling, make them have to do our best to improve their technical level, and constantly develop to meet consumer demand for new products, in order to gain a place in the market. In this way, will promote the development of the whole of the washing machine industry and upgrade.

Figures show that as of July this year, is still the leading haier washing machine industry, owns 31% of retail sales market share, and industry concentration increase again, the top three brands, the market share of 64%, up 8% year on year. This shows that industry brand competitive landscape is relatively stable, but due to the large market, product homogeneity phenomenon appears, the competition between enterprises is fiercer, especially in middle and lower reaches of small, is still on the stage of melee.

Review this year, washing machine market is sluggish, poor performance, entered the adjustment transformation. In this special period, market internal is not blindly depression, pregnant with a lot of gratifying changes at the same time, such as industrial upgrading, technology has increased, more intelligent, humane, antibacterial and health value of the presence of the washing machine and so on, these are the industry enterprises to seek new development, new breakthroughs in adjusting the transformation strategy. In conclusion, HCR (the study) that, in today's science and technology by leaps and bounds, technology is essential to the survival of enterprises, is also the development of the power; Competition for the enterprise created a sense of crisis, is a forward force, technology and competition together, will be washed out a new vision to the industry

In 2012, is the region's electricity industry for a year PCB

Wed, 20 Mar 2013 06:32:29 +0000

In 2012, is the region's electricity industry for a year, and rapid development of the electricity industry for a year.

From the start of 2012 together, happy and cool day, yao point 100, d cotton net electricity went bankrupt, was not involved in the failures of electrical business began to recruit a total of "winter". In September, red children sold to suning, suning to maternal and child class niche enclosure, accelerate the implementation "to DianQiHua"; In October, 1 store committed wal-mart, wal-mart in the electricity distribution have the foundation, and also 1 from wal-mart supply chain and financial support. During this time many appliance merchant giant more chaos on price, and attracted more traditional industry cluster into electricity.

But some electricity since the beginning of last year's continuing losses did not reduce the heat of the electricity industry, and jingdong "6 · 18 stores the anniversary," gome "7 · 18 - July 28 witness base coordinates", jingdong, suning "August 15 the price war", make the traditional industry of stunned taobao day cat "double tenth online carnival", one trillion yuan trading, prove that the future of e-commerce huge development space, is the rapid development of e-commerce in 2012 a year.

Groups of data and the nationwide sales of hot day, make traditional industry envy and chilling. Statistics show that as of June 2012, China's e-commerce market turnover amounted to 3.5 trillion yuan, up 18.6% from a year earlier. Electronic business service enterprise employees more than 1.9 million people directly, indirectly driven by e-commerce employment had more than 14 million people. The more striking electrical business on alibaba. As of November 30, 2012, alibaba's taobao and day cat transaction volume has reached 1 trillion yuan. This number accounts for nearly 5% of the total retail sales of social consumer goods across the country, 2% of national GDP in 2011.

Electricity, no doubt, is the brightest star of the industrial economy in 2012.

In the global financial crisis and China's economic slowdown, against the background of excess, loss, and low words constantly impact with the ball. Just for a fragile industry in our economy from crying, in 2012, but electricity industry have created a series of exciting moment and Numbers. Only "a" double tenth day, taobao and day cat is completed $19.1 billion worth of transactions. According to the national bureau of statistics released by the social total retail sales of consumer goods in October 2012, 19.1 billion yuan accounted for 30% of the total retail sales across the country.

The annual economic figures awards in 2012, alibaba group chairman jack ma, a decade later electrical contractor to take half of the retail market. This rhetoric attracted wang jianlin, chairman of wanda group "about gambling" : "electricity again, but business, such as showering, givegreat foot, ear cleaning, electricity cannot be replaced. I gamble with Mr Ma, in 2020, if the electricity retail market in China accounted for 50%, I'm give ma a $, if you don't have to, he also a $I."

Bosses "bet" let us from the madness of wake up in the thrill of electricity, more and more traditional industry no longer standing aloof, awakening to the electronic commerce and racing to electricity industry, the electricity industry is causing a new round of reform of the economy, also is a reflection of the society as a whole.

Purifier annual increase of 15% PCB

Wed, 20 Mar 2013 06:28:11 +0000

The masks sell large air stocks soaring air purifier sales rose, although parts of China haze dispersed by the wind, but the domestic industry has hit the air purifier concept to find business opportunities. Not only is the domestic manufacturers, foreign investors are also optimistic about the huge market, the United States, "Wall Street Journal" reported that private equity firms are looking for opportunities for investment in clean technology companies in China. Even foreign-funded enterprises recently transboundary launched air purification products. An air purification war is gaining momentum. However, industry analysts said, the existence of chaos due to the lack of uniform standards and other factors, this emerging industry.
Purifier annual growth rate will reach 15%
The data show that the use of various types of indoor air purifier in the Chinese market has just started in the initial stage of market introduction, the penetration rate of less than 1%, while the U.S. air purification product per capita was 31%. In 2012 the first three quarters of 2010, the air purifier volume of retail sales rose more than 11%, air purifier market will increase by close to 15%. 2012 air purifier reviews, "said the Chinese air purifier market size will more than 14.6 billion U.S. dollars in 2016.
Physical research environment quality monitoring center in Beijing Central engineer gold passers in an interview with reporters, said the future of China's air purification market to the development of several directions. First, the indoor environment pollution purification. Some will be favored with a clean indoor environment the concept of household appliances or furniture, such as some air conditioning with air purifier features. Personal Protective Equipment Market a lot of potential, such as respiratory masks. Purification equipment for industrial and mining enterprises, automobile exhaust, residents, sewage and other pollution sources. With the country increasingly stringent pollution source monitoring, purification equipment for pollution sources may have a greater development space.
The Swiss iqair ceo Mike Murphy said in an interview with reporters, the air purifier as early as a few decades ago has been around. However, until the mid-1980s of the last century, this product really open up the market. From a market share in the United States in a leading position in Europe in the second, but far behind in sales in the United States. In Western countries, more than 90% of the air purification device for allergy sufferers, pollen, pet hair, smoke, mold and dust produce serious discomfort. Chinese people more demand is filtering the industrial emissions of particulate matter. Pollen, smoke, dust and other particulate matter usually have a diameter of 1 micron to 25 microns, while the exhaust particles produced by the factory is relatively much smaller, therefore, a good effect in the Western countries purification apparatus may not be applicable in China.
The large area pm2.5 (diameter less than or equal to atmospheric particulate matter of 2.5 microns) poisoning cases may also promote the rapid growth of the industry of environmental monitoring equipment. According to statistics, in 2012 the country monitoring instruments installed probably over 1000. Industry insiders estimate that by 2015, there will be a demand for more than 3,000 domestic. It is reported that the 12th Five-Year period, the domestic construction nearly over 1500 pm2.5 monitoring sites, the initial investment will exceed 20 billion yuan.
A major source of air pollution, the Chinese government has specific provisions of the nitrogen oxide emissions of the power industry indicators. Provisions of the 12th Five-Year period, the thermal power industry nitrogen oxide emissions requirements 29% reduction; implementation of low-NOx combustion transformation in 2015, 70 million kilowatts of coal-fired units, the coal-fired units denitrification efficiency reached 75%. Analysts forecast, the denitration industry of the 12th Five-Year period will be explosive growth in the total market is expected to be more than 150 billion yuan.
Purifying effect as advertised
Now, each purification device in the market say that its purification efficiency of more than 99%, but I personally tested thousands of machines found, regardless of whether they are using what technology, failed to meet the instructions on the effect of almost every. Mike Murphy, good quality mainstream filter media and more elaborate textile, multi-layer overlay glass fibers. These filter media is dedicated to the filtration of particles less than 0.3 microns in diameter, the efficiency of more than 99.97%. That is, if there are 1000 particles pass through the filter, and an average of only three particles escaped. But I tested, many well-known filter is not only up to the standard of less than 99.97%, even 50% did not. Although the new products launched every month, but many businesses focused with the appearance of the goods, ignoring product performance, while the latter is an urgent need for consumer. Other countries in the world, the filters that meet the above criteria are often used in hospitals and aircraft within.
Another popular filtering technology is electrostatic ionization technique. Mike Murphy said, by ionizing particles by filtration device to a negative charge. Within the filter device with the positively charged metal grid, will be adsorbed on the above, when the particles pass through. Of course, the metal mesh to be out to clean up on a regular basis. Electrostatic purifiers problem is that it will produce a harmful gas ozone irritate the lungs.
Gold passers told reporters far as I know, our detection efficiency for purification of indoor purification equipment and there is no national standard, the conventional method is carried out in accordance with the detection method of indoor air standards, but the concentration of pollutants in the detection of environmental and purification factors such differences will affect the detection result of the purification efficiency. In addition, many users open the doors and windows using purification machines, there is no effect on indoor air purification, but standing on the user's point of view, long shut doors and windows, indoor severe hypoxia, affecting their health.
Pm2.5 monitoring equipment market, there are many problems. Way said, the Ministry of Environmental Protection issued in 2011 the pm2.5 detection method. However, due pm2.5 detection rise more rapidly verified by the relevant departments, not too many technical indicators comply with the requirements of the manufacturer of the testing equipment, may Yumuhunzhu. Ambitious indoor purifier official told reporters that the two problems, the pm2.5 monitoring equipment market: standard unified improve the quality of air in public places is not established, there is no cycle detection; buildings through acceptance into use before, no indoor air quality requirements. It is understood that the automatic air quality monitoring system in most markets by foreign control, even if the domestic equipment, key parts are also using imported parts in the United States. Because the pm2.5 the main basis for monitoring standards of the certification standards of the U.S. Environmental Protection Agency, the domestic manufacturers of monitoring equipment is subject to foreign standards.
Developed countries are still on the market
At present, Japan Air Purifier penetration rate of about 23 percent. Japan Air Purifier 1960s was the period of rapid economic development in Japan, the Japanese appear serious air pollution, the manufacturers are waiting for an opportunity to launch air purifiers, popular with the market. After that, the air pollution in Japan gradually been changed air purifier manufacturers in order to maintain the market, and constantly improve the product. Such as the increase to get rid of tobacco smoke, pollen, and other functions. The last 10 years, the Japanese home air purifier market is always in the position of tepid efficient humidification function air purifier, but has begun to enter the market, the market began to perk up. The relevant agencies forecast sales of Japan's future air purifier market share of more than 50% humidified air purifier possession. In order to expand its market share, the relevant institutions in Japan will also on January 19 of each year as the day of the air purifier, enhanced propaganda.
German air purification industry, domestic sales and export markets are the fire. Remember learned, there are two main blocks of the German air purification market, enterprises and social institutions, which are generally fitted with integral air purification system. If the air quality standards, the stores can not open the door, the enterprise could not begin. Home use, this type of market is the fastest growing in Germany. Like multi-layer filtration system was the product of German air purifier testing, including pre-filters, activated carbon filters, titanium dioxide filter, negative ion treatment. German air purification products go through the EU standards. Specialized agencies such as the German Federal Environmental Protection Agency has to intervene in the market for the products in question. Germany will also air purification products are exported to countries around the world, especially in China and other developing countries. However, many of the German people in the industry, more than half of the sales in China, the so-called German-made air purification products is not made in Germany.
The report published by Global Industry Analysts, Inc., 2017, the North American air purification equipment market will reach a value of $ 4.8 billion. This is mainly due to consumers' growing concern about the health provisions to improve indoor air in public places and government. U.S. indoor air purification equipment is mainly used for schools, hospitals, factories, office buildings and other public places, and finally home. Many machines at work will produce ozone, a greater harm to the human body. Consumer Reports Web site says, If I have to use a home air purification equipment, it must not produce ozone air purifier

PCB reliability in automotive applications is essential

Tue, 19 Mar 2013 08:53:20 +0000

PCB reliability in automotive applications is essential

Keywords: PCB reliability, power integrity, automotive electronics

Automotive electronics and other complex electronic products that it was not completely different: more central processors, network, real-time data collection, as well as a highly complex PCB. The design pressure of the automotive industry is similar to other types of electronic products: short design time, fierce competition in the market. Automotive electronics such as some high-end entertainment electronics What is the difference between? Different! If the PCB fails in entertainment products, the people's life is not threatened; However, if a failure in the car, people's lives at stake. Therefore, the reliability of the design of automotive electronic components is one of the main aspects that need to be considered in the design process.

Time and cost pressure

As with all products under design time and development cost pressure, automobile parts is no exception. Developed a practice to give electronics companies provide great help to meet these basic business goals, it is the use of virtual prototype design analysis, and without the cost and time to build a variety of physical prototypes to test these models, and based on the test results do out incremental modifications. In addition, many of the factors that affect the reliability of the product after a few weeks, a few months or a few years, the physical destruction can be found. Physical prototype is not feasible in these cases. Even in the cabin, you can not be accurate copy number of oscillations, thermal environment, vibration and temperature cycling damage.

Simulation is the key

Simulation, or virtual prototyping has become an increasingly important step in the design process. As mentioned earlier, the simulation not only saves time and cost in the development process, can also emulate a more long-term effect of abuse in the automotive harsh environment. As electronic Mentor Expedition Enterprise, a complex PCB systems design solution containing various forms of virtual prototype functions, including:

Analog and digital signal integrity analysis
Electromagnetic interference
Thermal Management
Power Integrity
Oscillation and vibration
Manufacturing Design

Use of a convention of all of these features are: A good designer will use all the functions in the entire design process, rather than wait until the last (Figure 1). Until the end of the process only when combined with the results of these simulations to redesign a waste of time and effort and is easy to compromise. Good virtual prototype integration design process will cause over-design (extremely conservative design approach), but usually such a result is to increase the cost of the product as well as a loss of performance, but also can not guarantee the continued reliability. Let's look at three cases in the product development process, of good virtual prototyping practice.

Figure 1 - virtual prototype should throughout the design process to be used, thereby reducing cycle time and costs, as well as to produce a reliable product.

Thermal control

Affect the reliability of the most critical point (here in terms of performance) is hot. Integrated circuit (IC) overheating problems over time, the car will become very ruthless environment. Overheating engine cabin parts, for example, or driving through the Michigan winter until the Arizona summer climate. From the beginning of the IC package, through the PCB, complete product until runtime environment, should be able to control the heat. Therefore, we need virtual prototype at various stages of the design has been to ensure that we have a reliable thermal products.

First IC suppliers usually analysis component packaging and thermal characteristics of the model. Then we hope to expand as the design of the stand-alone PCB analysis. PCB designers typically require the analysis of its working parts layout, and then determine whether they create a difficult cooled board. And this work is not only cursory consideration to the board with the device heat dissipation and distribution location. Many thermal path (radiator, the inner layer of the circuit board copper pass, conduction and divergence ......) and spread to the thermal analysis of the data from PCB design system must be complete. Analysis software setup and implementation must be fairly intuitive, because you hope that the PCB designers unnecessary to use the software thermal experts, and will not delay the design process.

The ultimate virtual prototype must be in the automotive environment can be expected under conditions of one or more of the final product enclosure PCB execution. This analysis is common in a typical mechanical computer-aided design (MCAD) system complete physical definition of the field of mechanical design, complete definition including housing, installation methods, radiators and hot rail, PCB and so on. PCB designers PCB design data must be passed to mechanical designers, embedded shell. MCAD need to have all the ingredients of the system the element its lead, as well as the complete product definition and thermal characteristics of the 3D physical. FloTHERM such software the mechanical designers then Mentor, the use of computational fluid dynamics and combined convection, radiation and heat conduction analysis to determine the IC is beyond the critical temperature, and whether it might cause reliability or performance issues.

FloTHERM now extends to not only be able to determine the temperature of the IC junction temperature guidance may cause problems, but also to the designers the reason and how to solve the problem. The software can identify "hot bottleneck" to show which part of the heat flow path is limited. Designers use this information to identify the component mounting technology, as well as alternative the PCB to shell better heat conduction path, and thus relieve the bottleneck.

Another valuable approach is to determine "hot shortcut that promote cooling potential design. The example of Figure 2 shows the determined the original fever IC issues and problem-solving shortcuts. This case, between the IC and the housing increase the filling pads, the environment can form a more direct path to the heat transfer. This simple change can make the the IC temperature decreases 74%.
Figure 2 - determine the thermal shortcuts to guide designers to make a change, so that the heat has greatly changed. About the new thermal analysis and guide function for more information, please visit www.mentor.com / flotherm.

Use in the field of PCB design and mechanical design of complex thermal analysis can lead to better thermal management and reliability, without the need to establish and test a variety of physical prototypes. This saves a lot of time and expense. With tightly integrated design system easy to use software, designers can quickly take advantage of a variety of "what if" scenarios to experiment and get better performance solutions.

Highly Accelerated Life Test

Another vehicle reliability problems because the PCB continuous vibration and subsequent component leads and accessories for failure. Usually by constructing prototype and they are placed in the acceleration chamber, so that the PCB occurrence of vibration and temperature cycle test, to detect whether the failure. As the design progresses, this approach needs to build multiple prototypes, and often take weeks or even months to complete the simulation of the life expectancy of auto parts in the acceleration chamber. This is a very time-consuming and extremely expensive process, so the reliability of the enhanced test may not be complete and comprehensive.

Currently, the software can carry out the same test in the virtual prototype mode. Designers can use this software to define the PCB and easy to carry the loss simulation. The software can be completed within a few hours of complex analysis, and pointed out that the possible failure (Figure 3). Of these failures can be corrected and re-launched in a new version of the design simulation. This iterative process can quickly get the appropriate reliability solutions. The early success of the Israeli Ministry of Defense to deploy the software in their new generation of the chariot. If the software can be in the extreme environment of the chariot of the possible failure analysis, then I will trust to apply it in my car.
Figure 3: Mentor HALT software can be completed in a matter of hours oscillation, vibration and temperature cycling failure analysis, and take several weeks or even months in the test room.

Power integrity analysis to ensure high reliability

Power integrity in electronic product design, is an increasingly complex issue. A few years ago, all the IC is in 5 volts, you only need a 5V power supply and ground layer can provide sufficient and stable power supply for parts. Today, IC can work in multiple voltage mode, the voltage can be as low as 0.9 volts. Therefore, a single printed circuit board requires multiple complex distribution network to provide the voltage and ground. In order to save costs, computer-aided design had to be more distribution network (PDN) into as little as possible in the ground layer. Results may appear as shown in Figure 4, the same distribution network, the interior space is very narrow (neck and downs), but the need for IC provides high current.

Figure 4: The the Mentor HyperLynx power integrity analysis can determine the high level current density of space and long printed circuit board failure may occur

Narrow space can lead to serious reliability problems, and the problem may become apparent after a few years. The current is too high, the space temperature rises, causing the PCB is the same as the fuse burned out or burst plate. Currently available software for these distribution network analysis, and can determine the virtual prototype and a high level of current density space. Then the designer will be able to space the enlargement or the adjacent layer to create a parallel current path, thereby to solve this problem while maintaining the IC sufficient current supply.

In the test chamber by using physical prototypes to test the current density problem is not practical, because it may be in a few years can lead to failure. The problem may never emerge, leading to the subsequent failure.

Conclusion

Reliability in automotive electronics is very important, but now in view of the pressure from time-to-market and cost reduction software virtual prototyping environment with respect to the analysis of the physical prototype test chamber approach becomes increasingly necessary. Due to the presence of the software, so that the electronic and mechanical designers can be more simulation program.

PCB board sectional system processes

Tue, 19 Mar 2013 08:41:24 +0000

PCB board sectional system processes

PCB board profile control system is an important element in the PCB design. But which involves sandpaper board is a harmful type of work, tracing lines (which is a simple duplication of effort), many designers do not want to engage in this work. Even many designers believe that the sectional system for PCB board, not the technical work, the primary design little training to do the job. This concept has a certain universality, but like a lot of work, PCB board sectional system or there are some tips. Designers to master these techniques can save a lot of time, can significantly reduce the amount of labor. Here we elaborate on this knowledge.

PCB board sectional system concept
Sectional system for PCB board schematic and board diagram (the PCB Figure) the process according to the original PCB board kind. Its purpose is for the late development. The late development, including the installation components, deep test and modify the circuit. Because they do not belong to the PCB board cross-sectional areas of system and the associated introduction only not going to elaborate.
PCB board sectional system processes
1, the removal of the original panel devices.
2, the original plate scanning, the graphics files.
3, the surface layer was rubbed off, to obtain the intermediate layer.
4, scanning of the intermediate layer, the graphics file.
5 Repeat steps 2-4 until all layers are processed.
6, the use of special software to convert graphics files for electrical relationship file --- PCB diagram. If you have the right software, designers simply graphical depiction again can.
7, check check, complete the design.
PCB board skills profile control system
PCB board sectional system profile control system, especially the multi-layer PCB board is laborious work, which includes a lot of repetitive work. The designers must have enough patience and careful, otherwise very error-prone. Good cross-section of the system PCB board design lies in the use of appropriate software instead of manual repetitive work, save time and accurate.
Profile control system must use the scanner.
The many designers habits PROTEL, PADSOR or CAD PCB design system directly draw lines. This habit is very bad. Scanned graphics files both convert to the PCB file late check basis. Using a scanner can greatly reduce labor difficulty and intensity. It is no exaggeration to say that, if we can make full use of the scanner, even if there is no design experience of personnel can also complete the sectional system for PCB board.
2, single direction grinding plate.
Some designers in the pursuit of speed, select bidirectional grinding plate (worn plate layer) by the front and rear surfaces to the middle layer. In fact, this is very wrong. Because the two-way grinding plate is worn out very easily, causing the other layer is damaged, the result can be imagined. The outer layer of the PCB board due process and copper foil, pads and other reasons the hardest, most soft middle layer. Therefore, to most of the middle layer, the problem is even more serious, and often can not be polished. In addition, the various manufacturers of PCB material, hardness, elasticity is not the same, it is difficult to accurately rubbed off.

pcb board warpage precautions

pcb board warpage precautions

The causes of the printed circuit board warpage, one aspect is a substrate used (CCL) may be warped, but in the printed circuit board during processing, due to thermal stress, chemical factors, and the production process properly will cause print system board to warp.

Therefore, for printed circuit board, first, to prevent occurrence of warpage of the printed circuit board in the process; then there for warping has appeared the PCB to have an appropriate and effective treatment methods.
First, to prevent the printed circuit board in the process causing warping
1, to prevent inventory the way improper or increase substrate warpage
(1) the CCL during storage, because moisture will increase the moisture warping, single-sided CCL area, if the stock higher ambient humidity sided CCL will significantly increase warping. Sided CCL moisture from the product end face only penetrate small area moisture, warpage change more slowly. CCL without proof packaging to pay attention to the coffers conditions to minimize the coffers humidity and avoid CCL bare put, to avoid increased stored in the CCL warping.
(2) CCL placed incorrectly, you will increase the warp. Such as the heel or pressure have weights on the CCL, CCL warpage placed poor will increase.
2, avoid poorly designed or processing the printed circuit board traces improper warping.
PCB board conductive line graphics uneven or both sides of the PCB board line significantly asymmetric, on one side there is a big area of copper to form a larger stress, warping of the PCB board high processing temperatures or larger heat in the PCB manufacturing process The impact will cause warping of the PCB board. Impacts of improper overlying plate board inventory, PCB factory is better to solve, to improve the storage environment and eliminate the heel can avoid stress. The line graphics there is a large area of copper PCB board, the best of the copper foil grid to reduce stress.
3, to eliminate the substrate stress, reduce the process PCB board warpage
As the in PCB processing process, the substrate to be repeatedly subject to the action of heat and subject to the role of a variety of chemical substances. Substrate etching after washing, drying and heat pattern plating Electroplating is hot, the printed green oil and printed logo character to use heating drying or dried with UV light, the hot air HASL when substrate by thermal shock also much more. These processes may cause the PCB to warp.
4 wave or dip soldering, solder temperature is too high, a longer length of operating time, will increase substrate warpage. For wave soldering process improvements, you need the co-electronics assembly plant.
Since stress is the major cause of warpage of the substrate, and put into use in the CCL before baking sheet (also called Baked plate), the number of PCB plant believe that this approach helps to reduce PCB board warpage.
The role of the baking plate can be so that the stress of the substrate is sufficiently slack, thus reducing warpage of the substrate in the PCB manufacturing process.
Baked plate method: conditional PCB factory large oven baked plate. Before the commissioning feeding heaps CCL into the oven, the temperature of the vicinity of the substrate glass transition temperature will be a certain number of hours to ten hours CCL baking. Production of PCB board after the the baked board of CCL, warpage is relatively small, many products of a high pass rate. For small PCB factory, if not so large oven substrate cut into small pieces and then bake, but baking sheet should heavy objects on the board so that the substrate to remain flat in the stress relaxation process. Bake plate temperature should not be too high, too high temperature substrate will change color. Should not be too low, the temperature is too low to take a very long time to make the substrate stress relaxation.

The composition of PCB price

Tue, 19 Mar 2013 06:54:12 +0000

The composition of PCB price

Many buyers have been ever puzzled in pcb price, even though some have many years experience in PCBprocurement staff have full understanding herein it may not be the whole story in fact, PCB prices are set by the composition of the following factors:

1. Different PCB materials used cause the price of diversity

As the ordinary double sided pcb for example, generally there are materials of FR-4, CEM-3, etc., thickness ranging from 0.6mm to 3.0mm, Cu thickness from ? Oz to 3 Oz different, all these on a sheet has caused a huge price difference; the solder resist ink, the ordinary heat-sensitive green oil and oil there are some price difference, which caused the price of materials of different diversity.

2. Different PCB production process caused the price of the diversity

Different production processes result in different costs. Such as gold plate and spray tin plate, making the shape of the gong (milling) board and beer (red) plates, using the screen printing line and dry line, and this will form a different cost, resulting in the price of diversity.

3. The difficulty of PCB caused by the diversity of different

Even if the same material, same process, but the difficulty of different PCB itself can also cause different costs. Such as two circuit board has 1000 holes, a plate diameter greater than 0.6mm and another board is less than 0.6mm diameter drill hole will form different cost; such as two others of the same circuit board, but the width line from a different, a greater than 0.2mm, less than one kind of 0.2mm, can also cause a different production costs, the board scrapped because of difficulty higher, the inevitable cost increase, thus causing the price of diversity.

4. Different requirements will result in different prices.

The level of customer mill will directly affect the yield, such as a board according to IPC-A-600E, class1 require a 98% pass rate, but may be required by class3 only 90% pass rate, resulting in different costs, leading to changing product prices.

5.PCB manufacturers in different price due to the diversity

Even if the same product,because different technology and equipment from different manufacturers, different levels of technology, will form a different cost, nowadays many manufacturers like to produce gold-plated board, because the process is simple, low cost, but some manufacturers to produce gold-plated board, scrap the rise, resulting in higher costs, so they prefer to produce spray tin plate, tin plate and thus offer their spray but lower than the gold plate.

6.Payment of price differences caused by different

The current PCB mill usually adjusted according to the different ways of payment PCB price ranges from 5% -10% range, thus causing the price differences.

7.The diversity of the region caused the different price

Currently geographically speaking, from south to north, prices were increasing trend, there are some differences in prices in different regions, which also caused prices in different regions of diversity.

Not difficult to see through the above discussion, PCB price diversity is a necessary factor of its intrinsic, this section provides only a general price range for reference, of course, you can learn from the manufacturers directly about the specific prices.

China is in the high field of screen printing industry

Tue, 19 Mar 2013 06:51:30 +0000

China is in the high field of screen printing industry

Rising costs of raw materials, textiles, clothing and other processing industries no longer be devastated, people increasingly see the drawbacks in the international industrial chain, lack of work, appreciation of the renminbi, freight and other such factors in a variety of painful problems of small and medium enterprises, it seems not any export in the market. Transformation becomes the only way for their living. Silk screen printing industry, textile, garment close relationship with the printing processing industry has also experienced the same test. The difference between textile and garment enterprises is that our screen printing industry has a good foundation on independent research and development, brand, especially in high areas, China's silk screen printing companies are facing rare development opportunities.

The high areas of screen printing industry PCB, solar, LED, etc. is now surging. National strategic priority, build a base of strength, alliances have settled in China. This iss closely related to intense competition of the market situation and the high demand for electronic products in mainland China.

Development of an industry often experience the brutal elimination of price, but it will eventually establish a new order within the industry, which mature and stable development. Silk screen printing industry, some areas have begun to this phase. Gradually rising manufacturing costs in China, period, instead of waiting to be forced to upgrade, as transformation initiative, seize the opportunity to grow rapidly, using a variety of favorable factors, the road to higher value products.

Status: price competition

The disorderly competition and rising raw material prices led to war in some areas.

Traditional printing to intense market competition, involved in the decline in foreign orders, high costs, low profits are frequent, bringing upheaval to some SMEs, the high price of raw materials, unstable operation is panic.

The Ceramic Decal printing supplies are also part of such a situation, although the market is enormous field, it was disorderly competition led to price wars, andit also a low-margin, such as ceramic flower paper industry. In China's annual exports of about 14 billion ceramics, as well as the domestic market of the ceramic can be described as a huge space, but low-profit enterprises have tasted tasteless

Good: the layout of the domestic high-tech fields

Screen printing technology, key application areas show the fascinating high-tech future, PCB layout fade in the strength of the industry, LED, solar, touch screen glass as the industry continued capital investment hot spots, the worldwide base there. This is mainly due to the demand for electronic products, terminal growth spurt and led a national strategic planning.

IC industry is a national strategic and emerging industries,an important foundation of national economic and social information. China is becoming the world's fastest PCB growing region. China's PCB industry base in the early effects, including Shanghai, Jiangsu and Zhejiang Yangtze River Delta region are the major domestic integrated circuit development and production base in China's IC industry occupies an important position. Benefit from notebook computers, smart phones and tablet PC market such as the rapid development of electronic information technology, PCB industry maintained a rapid growth. According to statistics, now the world's gross national product to 65% on the same integrated circuit.

Also be a strong economic future chasing LED industry, there has been a big move. Powerful combination of the three places, led lighting and create the world's largest chip production base.The Kaifajin Lighting(Xiamen) Co., Ltd. made a foundation which is invested by the four world's leading photovoltaic companies in Torch High-tech Zone in Xiamen. New investment to build a developing grain project, plans a total investment of nearly $500 million,The investors are the industry leaders. Such as the China Electronic Information Industry Group is the largest state-owned IT companies, TPV Technology Group.

In addition, the solar industry for highly sought by each countries action frequently at the same time.

June 12, CaiXin Energy Tech nology Co., Ltd. in Taiwan signed a letter of intent to adopt and invest in Sichuan Panzhihua municipal government, plans to invest $200 million building southwest of the city's first CIGS (copper indium gallium selenide) thin-film solar cell project.

China solar cell's good selling in foreign markets is to bring great confidence. While the domestic market is not so hot as international market, but as people's environmental consciousness, the domestic market to heat up just a matter of time.

China's high area of ??the blank glass was broken in June also. By the state-controlled Yufei Henan Electronic Glass Co., the construction of the first domestic production line of touch screen cover glass Zhengzhou Economic and Technological Development Zone in the foundation-stone laying. Cover glass touch screen, high smart phones, tablet PCs, flat panel TVs and other industrial and commercial areas of the touch screen is essential. Glass screen printing is a hot spot of the field.

A variety of data and market show a great potential ability for development in high screen area. In strengthening their technical and business development efforts at the same time, all sides of resource use, especially with the seamless cooperation of upstream and downstream industries, has become a trend.

For many materials, processes, equipment is still dependent on imports of high-end screen printing field, how to share the enormous prosperity to the industry, called cake, take the road of national self-reliance, may be placed in front of the important issues of domestic enterprises.

Analysis of no copper in PCB sink holes

Tue, 19 Mar 2013 06:49:44 +0000

Analysis of no cpper in PCB sink holes

Different resin systems and materials board also led to the differences on activation effect of PTH. In particular, the specificity of some CEM composite base plate and silver plate high substrate, when making electroless copper process, need to take some of the more special way to handle it, if the normal electroless copper is sometimes difficult to achieve good effects.

Substrate pre-treatment issues. Some substrates may absorb moisture and their own part in the pressure when the synthetic resin substrate bad, it will be caused drilling of poor quality because the resin is strong enough itself, drill hole wall resin dirt or tear more serious digging, etc. Therefore, it is necessary to baked when the material opened. In addition, some plywood laminated may also occur after the prepreg substrate area branches curing bad status, will also directly affect the activation of the drilling and desmear Shen copper. Poor drilling conditions, mainly as follows: multi-hole resin dust, hole wall roughness, burr empty grave, burr hole, the inner copper nail heads, tear section of glass fiber length of missing areas, all are caused some quality problems of the chemical copper.

In addition to clear the substrate surface contamination and remove burr holes, the surface cleaning, in many cases, also play a role in cleaning to remove dust hole. Especially more important when dealing with double-sided adhesive residue process. Another point to note, we do not think you can have desmear glue residue and dust out of the hole, in fact, in many cases, desmear dust treatment process on a very limited effect, because the dust will form in the bath in a small plastic group, so it is difficult to deal with the bath, the micelles adsorbed on the pore walls may be formed hole plating tumor, may also be in the subsequent processing off from the hole wall, this may also result in copper-free point-like hole, so it is necessary to machinery and high-pressure cleaning for multi-layer and double-sided boards, especially facing the industry trends, high aspect ratio holes boards are more and more common. Sometimes ultrasonic cleaning to remove dust hole has become a trend.

Reasonable and appropriate desmear process, can greatly increase the hole than the combination of strength and inner connection reliability, but in addition to rubber technology, and related problems of poor coordination between the bath will also have some occasional problems. In addition to lack of glue residue will cause micro-hole wall voids, with inner bad, out of the hole wall, blow holes and other quality problems; in addition to excessive plastic, glass fibers may also cause prominent hole, hole rough, cut-off point of the glass fiber, copper infiltration, inner wedge-shaped hole breaking the separation between the inner layer of copper caused by the black hole or discontinuous copper fracture coating or plating folds increased stress and other conditions. Another important reason is a few control problems of coordination between the bath.

Bulk and swelling, this could result in less residue than plastic; swelling transition out of the divisible is more fluffy resin can then change out the copper sink copper sink will also not bad on activation, even on copper sink is also after the resin in the production process, there may be subsidence, holes and other defects from the wall; plastic tank in terms of the addition of new slots and higher processing activity may also be some of the less-connected dual-function single-function resin and some three functions in addition to excessive plastic phenomenon, leading to prominent hole wall of glass fiber, glass fiber and is more difficult to activate compared with the chemical bonding copper and resin between the worse, because after PTH is extremely uneven coating on the substrate in the deposition of chemical copper stress will increase exponentially, you can clearly see the hole wall after the chemical copper sink copper piece off from the pore walls, resulting in no follow-up hole copper produced.

The following is my personal opinion with the hole open and non-copper control. Resulting hole is no other reason than copper:

1. Plug the hole or holes drilled by thick dust.
2.When PTH syrup bubbles, not sink hole on the copper.
3.There is the line ink in the hole, not power on the protective layer, hole-free copper etched.
4.The power acid solution is not clean after PTH, parking so long, as result in slow bite corrosion.
5.Improper operation, to stay too long when the micro-etching process.
6.Red plate pressure, the middle of neat disconnected.
7. Plating solution (tin, nickel)is poor penetration

To solve the seven problems above, we can do as below:
1. Prone to dust on the holes (such as the following 0.3mm diameter with 0.3mm) to increase high-pressure washing and desmear process.
2.Activity and shock effect to improve medicine.
3.Change the printing screen and the counterpoint film.
4.Extended washing time and provided to complete the pattern transfer in the number of hours.
5.Set the timer.
6.Increase the explosion holes. Reduce board stress.
7.Regular penetration testing.

The solution instance Amber for fog acid copper

Tue, 19 Mar 2013 06:48:09 +0000

The solution instance Amber for fog acid copper

Problem:

Copper slot fog, we can exclude the possibility of overdose of MU and B agents, the situation is much better after the big deal, but it can not cover off the fog in these couple days, and the more obvious the fog is the longer nickel-plated,once a good-plated copper piece on the potassium dichromate in the wash, after activation to the nickel in white mist can be built out of low areas on the coating, but not bright, no light, low-area Hall Cao serious hit film white mist, high-brightness area is poor, high temperature treatment effect is not obvious, and a light coating on the whole are slow.

Solution ways：

1、Light dose offset

Dose is too high

Imbalance agent may be light, what with a small amount of activated carbon adsorption, or you continue to do two specimens without light agent, general agent A consumption to be bigger, hit the third time in the test piece to see, is that which less than, plus hydrogen peroxide, activated carbon filter to clean and bath, plus temperature to 70 degrees, electrolytic processing hours, until when the coating even after electrolysis, electrolysis can be alternating current size, then add the normal ratio of light agent. General lack of chloride ions when the color will be darker bright.

2、Oil Plus sodium lauryl sulfate, add toner to mix a clean filter

3、As we all know, MN-based bright acid copper plating bath to be used include chlorine ion, including five to six kinds of brightener. The proper ratio, the brightness of the coating, leveling of the excellent high temperature characteristics of a good bath; but serious imbalance, its processing requires some experience and simulation tools.

Tue, 19 Mar 2013 06:41:27 +0000

News that HP Slate 7 tablet by byd foundry

Beijing time on March 14 news, according to a technology blog, MarketWatch reported, according to people familiar with the byd electronic (international) co., LTD., has won the HP Salte 7 tablet PC OEM contract, it also broke the Taiwan enterprises in the monopoly position in the field of tablets.

In the field of tablet PC OEM, Taiwanese companies such as hai hong precision industry, quanta, compal electronics, pegatron has been dominant, the enterprise technology also has a scale, it has to offer attractive conditions to win the order. So when HP decided to Salte 7 tablet PC OEM contract to byd, which also makes the industry was very surprise.

Arthur, an analyst at UBS (UBS), Hsieh said although byd, mainly by the production of electric cars and batteries and known, but the company attaches great importance to tablets, and in the past few years quietly established subsidiary of byd electronic production line. Now, byd has begun to win the trust of some customers, get a small amount of order, but due to lack of experience and the scale, byd is very difficult to become contract's main rival Taiwan.

Byd declined to confirm HP Slate has won 7 tablet rumors generation of labor contract, the company said in a statement: "byd is actively expand tablets, but now can't provide any details."

HP said in a statement, Slate 7 of the contract for the product solution provides the best quality and cost.

Google Nexus 7, in order to the amazon Kindle Fire HD tablet competition, HP in this year's mobile world congress 2013 (MWC) released the first Android tablet on the Slate 7. The tablet running Android 4.1 operating system, configuration of ARM cortex-a9 dual-core chips, with 8 gb of storage space, and can be expanded by a SD card slot storage capacity. Slate 7 the fastest will be listed in the U.S. in April, the lowest price is $169.

In addition, according to people familiar with the matter, h-p isn't used in Slate 7 qualcomm or nvidia processor, preferring another Chinese mainland companies - Fuzhou core microelectronics Co., LTD (Fuzhou Rockchip Electronics Co) as chip suppliers.

Sanford c. Bernstein analyst Alberto Moel pointed out that although byd electronics companies in mainland China is hard to threaten Taiwan foundries dominance, but HP choose cooperation with byd, also shows that the enterprise's technology ability is rapidly improving in mainland China.

In the next few years China's PCB production will account for 45% to 45%

Tue, 19 Mar 2013 06:38:56 +0000

n the next few years China's PCB production will account for 45% to 45%

China's printed circuit industry association (CPCA) vice director and secretary-general Wang Longji 14 in "expo 2013 Shanghai international informationization TongQiHui news" said, in 2012 China's printed circuit board production and sales have accounted for 40% of global production, in the next three to five years will be close to 45% of the world - 50%.

"Due to the growing Chinese enterprises and the overall technology promotion, is expected to last three to five years, China's production and sales will be close to 45% of the world - 50%, and the world advanced level", Wang Longji said.

Printed circuit board is one of the important components of the electronic industry, mainly to prop up the electronic components and connection. According to Chinese CPCA statistics, in 2006 China's printed circuit board production has more than Japan to become the world's first. Although industry accounts for about forty percent of the world, but at present China's printed circuit board industry in the overall technology level, still lags behind that of Japan, China Taiwan, South Korea, the United States, Europe and other places.

By radium, chairman of the China's printed circuit industry association said recently, in 2013, although the whole electronic industry facing the external environment still has high uncertainty, but China's printed circuit board practitioners still confidence of their own competitive advantage and foreign counterparts, the domestic enterprise has a strong domestic market to support industry development, the labor cost still have comparative advantage; Compared with southeast Asia, India, Brazil and other countries, China's printed circuit board companies have incomparable perfect industry chain supporting these areas.

But at the same time, the experts, at present China's printed circuit board industry is also faced with transition, enterprises need to gradually from the past and investment-driven growth turned to natural growth driven by innovation quality.

[news] in the first quarter of 2013 the mainland and Taiwan PCB with ZengChanZhi

Taiwan PCB association (TPCA), IEK forecasts, season 1 Taiwan business people on both sides of the printed circuit board (PCB) output value 132 billion yuan, a 6.8% increase over the same period last year. Listed ark PCB factory in January of this year sales have JingPeng industrial (2355), JingShuo technology, xu soft electronic record; Jian ding technology of record for 21 months, total societe generale is historically high.

Have adverse factors such as the European debt crisis last year, TPCA, IEK statistics, Taiwan business people on both sides of the PCB production value 521.8 billion yuan last year, there are still grew at 3.08%, only 0.84% better than the year before last, last year and a quarter by quarter growth trend, in the fourth quarter climbed to the top the annual peak.

TPCA, IEK estimates, last year's fourth quarter on both sides of the Taiwan businessmen output value 138.2 billion yuan, better than expected, JiZeng rate 4.6%, last year's season in the champions league, grew at 6.5%, with high-density connection board and flexible printed circuit board (HDI) best delivery.

Fri, 15 Mar 2013 06:47:31 +0000

31 gw pv market is expected to reach 45% in 2013 for above ground installation

NPDSolarbuzzMarketbuzz2013 new report shows that 2013 pv demand is expected to increase 7% year-on-year, up to about 31 gw.

The market research company has said that 2012 pv demand has reached 29 gw.

China is expected to become the biggest market, for the first time more than Germany. NPDSolarbuzz said, in fact, is fast becoming the biggest market in Asia, China, Japan, and India is expected to 2013 accounted for 36% of global pv demand.

NPDSolarbuzz senior analyst Michael barker (MichaelBarker) said: "2013 will be a gap year, due to the photovoltaic industry to adapt to the traditional weakness in European markets. China will end market to a great extent, make up for the German demand decline, and led a pv demand in Germany."

Due to continue reducing the European feed-in tariff, is expected in 2013 will be a sharp drop in demand in Europe. The market research firm, expects year fell 26%, fell to about 12 gigawatts (gw). NPDSolarbuzz said that European demand is 16.48 GW in 2012, accounts for about 60% of global demand.

Demand growth in China, Japan and India, however, expected eventually to European demand and its growth rate more than 50% in 2013, accounted for more than 11 gw in pv demand. In 2012, is the second strong market in Asia, demand for 8.69 gigawatts (GW).

Buck added: "in 2013, we expect to see the market fundamentals to improve, make pv demand a return to double-digit growth. Installation system prices will continue to decline, and in high electricity prices, domestic supply shortages, and to fulfill its obligations to renewable growing area, photovoltaic will become increasingly have cost competitiveness."

Above ground installation growth and housing

Mainly due to the local government for subsidies to major markets, the ground installation of photovoltaic (pv) is expected to account for 45% of global installations, and the housing market is expected to remain at around 20%.

Housing markets are Japan, Germany, Australia, Italy and Britain and other countries to actively support, is expected this year are expected to account for all these countries three-quarters of the residential pv installations.

Overall, 2013 top 10 pv area is expected to account for 83% of global pv demand.

Micro market

Photovoltaic components and the market research company, warned that balance system components of the supply chain rupture are expected to continue affecting the whole market, due to the geographical changes in access, import of new and ongoing trade barriers and changes in the field of photovoltaic applications.

Buck said: "global trade and excessive levels of local manufacturing capability, will create microenvironment for pv supply and demand, each pv suppliers is only 31 gw a fraction of the total demand."

In FinlayColville NPDSolarbuzz vice President of a new guest blog, Colville, due to the phenomenon of micro market development momentum, expounds the important changes in the regional market.

Large size LED TV backlight needs strong factory revenue is expected to supplement

Fri, 15 Mar 2013 06:37:40 +0000

Large size LED TV backlight needs strong factory revenue is expected to supplement

Large size TV back light applications will become 2013 LED industry sales growth as the main driving force. Over 50 inches large size TV rapid change red, in the market to drive the LED back light demand rise sharply; Aimed at the business opportunities, LED grain and FengZhuangChang spirit full screens, you have period high related products sales, for full-year revenue to inject considerable contribution.

2013 light-emitting diodes (leds) manufacturer's revenue. More than 50 inches in 2013 big TV market penetration continues to climb (figure 1), at 10%. In 2013, according to NPD DisplaySearch forecasts, global more than 50 inches large size TV shipments proportion stable growth, particularly in the United States market has been close to 20% of the total shipment, about 10% of the proportion of the following is higher than other areas.

Figure 1 in 2012 ~ 2013 TV panels factory shipment plan according to size comparison source: NPD DisplaySearch (01/2013)

Increase of price falls this year LED backlight production declined slightly

Benefit from large size TV shipments to detonate, LED back light of the demand is also significant bullish. But notable is, in 2013 the LED back light the size of the market continues to expand, but under the LED to a glut on the market, the LED unit price a sharp dip, the global LED back light overall output, this year will be slightly reduced.

Economic institute industry and trend research center (IEK) energy saving technology research, researchers said Guo Ziling 2013 smartphone and the television is still the LED back light growth of main engine, among them, the large size display LED back light is LED back light unit shipments in the world more than 50%, as around whole LED back light source is the key to market value.

Guo Ziling further pointed out that despite the large size display LED back light 2013 years demand growth is strong, but for use in television edge-lit LED back light LED encapsulation type 7020 as an example, the price more than $0.2 in 2012; Price has fallen to 0.18 ~ 0.2 $2013, in order to estimate, in 2013 the global medium size display back light of the overall market value will sharply decline.

It is worth mentioning, however, due to more than 50 inch big size TV shipments this year to increase "significantly", is expected to fill the vacancy LED output falling fast in the unit price, let the world in 2013 LED back light output only falling slightly.

It is understood that at the current mainstream 42 inch low straight down type LED back light, leds used for about 40 to 48, accounts for the LED back light whole material list (BOM) costs are as high as 51%, about 12 ~ 14 dollars; Edge-lit LED back light is about seventy-two, accounting for the LED back light BOM cost about $23 to 26. As to 55 inches of big size TV edge-lit LED back light, LED use over a number of about one hundred and sixty, which accounts for up to 27 LED back light BOM cost ~ 30%, about $110 to $115, obvious 55 inch big size TV for LED back light output of the pump.

Engineering institute IEK estimates, 2013 years of large size display LED back light output value up to $3.01 billion, compared with $3.05 billion in 2012, only a slight drop in proportion, the big size TV have accounted for large size display LED back light containing more than 10% market share, and each year will maintain two digit rate of high-growth, incentive medium size display LED back light will be a great kinetic energy market growth.

In addition, more than 50 inches in 2013 large size TV market is rapidly expanding, also make the demand of edge-lit LED back light with a rising tide lifts all boats, incentive ronda electronics, wafer photoelectric, in January in the new century photoelectric, ladies round LED manufacturers such as revenue growth.

Large size TV order supplements LED watch factory camp qiao

Ronda electronic Zhang Bo apparatus, a chief financial officer and spokesman, said in 2013 LED TV penetration rate rise sharply, the company will actively strive for more customer orders.

Ronda electronic Zhang Bo apparatus, a chief financial officer and spokesman, said the company article 32 to 55 inch LED TV, lamp product proportion increase, with the straight down type backlight products, including LED encapsulation) continue shipping to mainland China and the United States brand customers, coupled with the lighting applications increase Japanese brand OEM customers, so the revenue in January has been a surge in December 2012, amounted to nt $950 million, a 31.7% increase in December 2012, a 46.1% increase over the same period last year.

Zhang Bo instrument, points out that LED back light penetration in the television market is expected to grow from 60-70% in 2012 climbed to nearly 90%, and ronda electronic and power combined effect has reaction in advance, in mainland China with the LED TV market in the south was very successful in work, whether the machine factory, panel manufacturers or upstream supply chain, such as customer master, will seize the LED TV market in 2013 permeability rising point.

The ronda electronic except epitaxial, grain size and system according to below 50 inch lower prices straight down type and big size TV edge-lit back light, has respectively developed a 3535, 3030, 3528, 7020, 7030, such as encapsulation of LED, according to the different customers' specifications.

Also took the straight down type and low edge-lit LED TV business opportunities, wafer photoelectric, ladies, in the new century photoelectric LED grain manufacturers such as in January 2013, revenue hit, wafer photoelectric revenue breakthrough, in 2012 to nt $1.35 billion; Ladies circle and in the new century photoelectric also reached nt $300 million and nt $270 million of revenue. Among them, the wafer photoelectric, ladies for Korean brand manufacturers outsourcing OEM orders, revenue growth, order visibility up to end of season 1.

In addition, in Chinese mainland TV brands such as skyworth, hisense, TCL, konka, changhong and other LED TV under shipment quantity increase, Taiwan LED grain companies will have the opportunity to better product quality, to enter the Chinese mainland TV back light source in the supply chain, to inject considerable revenue contribution.

SheQingWei analysis, an analyst at NPD DisplaySearch, Taiwan branch, 2013 LED TV total TV market share in the world will be as high as 88%, among them, the straight down type 50 inches below the low LED TV market penetration will grow to 19%, from 11.3% last year, however, edge-lit LED back light (including large size TV back light) still account for the LED TV market share as high as 80% above, still for the largest market, as LED manufacturers, main market.

SheQingWei analysis further, despite more than 50 "of big size TV LED TV market share is still low, only about 10%, but the back light use of LED for more than 50 inches below the TV a lot, so will also be LED grain and FengZhuangChang important sources of revenue contribution.

As for large size high resolution (UHD) TV has industry is the focus of attention, but the market is entering the bud, so compared to the large size TV 1080 p, 2013 for the LED manufacturer's revenue contribution is relatively limited.

Lower shipments UHD revenue "dead"

UHD TV market penetration of less than 1% in 2013 (figure 2), for the LED back light of the demand is low, so the LED supplier revenue proportion is not high.

Figure 2 2011 ~ 2016, the regional market UHD TV shipment quantity forecast data sources: the NPD DisplaySearch (01/2013)

Guo Ziling said the UHD TV brands is by a small amount of high price of high power leds, or more a combination of several low power LED, to achieve high brightness LED back light of the requirements, therefore, compared with 1080 p resolution LED TV, UHD TV LED back light BOM cost is expensive. Even so, conditioned by UHD TV shipments in 2013 is still low, so the injections LED manufacturers, there is no significant proportion of turnover.

NPD DisplaySearch forecasts for 2013 global sales growth of the television, will amount to 222.6 million units, of which only five hundred thousand units in UHD TV shipments, the city accounts for around 0.2%. Thus obvious, UHD TV will not be LED back light of the main market.

It is understood that the present stage UHD to 55 inch TV edge-lit LED TV as an example, the 1080 p resolution LED back light BOM cost up to 110? $115; The UHD TV LED back light BOM cost was more than 8 ~ 10%.

Guo Ziling pointed out that the UHD TV LED back light has entered the stage of Design (Design) In the import, is expected to 4? May will start to pull goods, in order to estimate, in the second half of 2013 UHD TV shipments will rise rapidly.

Faced with big size TV shipments will go Yang, 2013, Taiwan LED manufacturers are actively strive for more orders, shipments, in order to improve its products, through which to inject a higher revenue contribution, will be an important source camp growth.

Smart TV is facing and simplified choice: heavy function or market

Fri, 15 Mar 2013 06:35:34 +0000

Smart TV is facing and simplified choice: heavy function or market

Along with the rapid growth of the smart TV market share, consumer complaints also become high. Sometimes smart TV operation has become a trial to customers. In this context, simple and easy smart TV be vividly portrayed. Summary the emergence of the smart TV market will impact the original products. The industry faces a dilemma again, simple quickly old product price rate will lead to further increase, adhere to the production of complicated smart TV means out of the mainstream consumer market.

Consumers are looking forward to simple TV

Simple and easy to use smart TV will become the customers first choice. , an industry body by horizon research consultancy group in Beijing, Shanghai, guangzhou, chengdu, nanjing and other 20 key cities in 25-40 years old have to buy smart TV and TV white-collar crowd demand investigation, and released the first China smart TV market research report. Data show that the smart TV is close to fifty percent of the total sales of flat-panel televisions. With the ascension of the smart TV market attention, many problems affect the healthy development of the smart TV is increasingly exposed. Look from the survey, sixty percent of consumers know about smart TV is still not enough, smart TV has yet to establish a clear image in consumers' mind. Remote control operation inconvenience, slow speed is the current user on the most frequently encountered problems when using smart TV.

This problem from the smart TV is plagued by many consumers, at the beginning of the birth of electronics analyst liu buchen thinks, in order to enhance the level of performance, domestic enterprises have the promotion of smart TV, but at the moment the use case, smart TV activation rate is low, its basic reason is that not convenient operation. Don't solve this problem, the popularity of smart TV is more difficult.

Market calls for a simple and easy smart TV available as soon as possible

This background that the whole industry began to rethink. In the current "two sessions", the National People's Congress, hisense zhou houjian, chairman of the special with the development situation of smart TV bill is put forward. Zhou Houjian think smart TV has more brand-new recreational experience for consumers, is the application of smart TV in 2013, ninety percent of consumers prefer to buy smart TV. But TV operating systems on the market is more and more multifarious, the volume is bigger and bigger, more and more remote control buttons, greatly hindered the consumer applications for smart TV interface design chaos, is not easy to find the content and intelligence applications for the problems of the slow running speed has been dampened consumer purchase intention.

Most color TV enterprises face a dilemma

Zhou Houjian, during the "two sessions" to the Beijing business newspaper reporters, who is the smart TV is more simple and easy to use, who have more product market competitiveness. Hisense would solve smart TV as soon as possible the existence of "trouble", he said, disclosing that hisense invested large capital for a new round of competition, is simple and easy smart TV will come out soon. This could trigger a new round of competition.

Zhou Houjian's position will be the future development of industry to the forefront, as future sales of TV, smart TV is simple or complex, from the industry.

Have declined to be named enterprise representative pointed out that a simple smart TV does not have to get the welcome of consumer, only functions, rich application was welcomed by consumers, so smart TVS on the market at present still have space.

Jin Xiaofeng wyman analyst pointed out that the enterprise concept is in fact of strangeness, rich functions, the application does not necessarily mean that the operation is complicated, industry calls for simple and easy smart TV is actually refers to the function and the application does not reduce, easier operation. The enterprise's position in fact reflects one kind of complicated mentality. Blatantly calling for simple means that tedious television before depreciation rate is greatly increased. This blow simple smart TV's purpose is to delay the time, slowing down the development of the industry. Enterprise will speed up to clear inventory at the time, was secretly follow up your TV. Because who pioneered simple and smart TV, who is leading the market.

Fri, 15 Mar 2013 06:30:24 +0000

Huaqiang north road, or electronic components industry for over 3 years to counter attack

Back in 2012 electronic components market, electronic components development by the rising popularity of terminal market, especially with the development of the mobile terminal industry mature and scale, the vendor's competitiveness continuously increased, market demand is expanding. This year, the momentum is still keep upward trend, in April, but also usher in the peak season demand.

However, as China's largest "China construction first street", built by metro line 7, on February 27, 2013, huaqiang north road, a road for three years to officially kicked off. Throughout the overall market, electronic components is a trend, and in good time, huaqiang north business the lifeblood of life and death is uncertain.

Many businesses worry, subway construction will affect the huaqiang north road traffic, leading to reduce the passenger flow. In the face of the irresistible objective factors, we will how to breakthrough in trouble again, to find a new way?

One, grasp the market dynamics, analyze their own advantages and disadvantages.

Any time, the market dynamic is the root of business. The dynamics of the market, on the one hand, policies, rules and regulations issued by the government, the role of the market tend to be efficient and effective. Policy execution, in macroeconomic plays an important role; Second, the upstream and downstream changes in the market. This change needs to be in the long-term business activities in the exercise a keen precognition, is a guide to the market and competitor change industry plays a role cannot be underestimated.

Second, through various channels to expand customer base, don't dwell on entity counter.

One attack, multilateral support. Entity market trapped, counter time shift does not walk, can't immediately to other electronic market. So, we will consider to not region, the time limit of the network platform. The era of such rapid development in electronic commerce, the network already is nothing new. Like sitting in huaqiang north commercial circle huaqiang electronic network, relying on the convenient geographical position, to the entire electronics industry chain business platform. A decade for many electronic components business provides a window without geographical restrictions.

Customers in addition to the market, there are also a lot of potential vendors, customers market counter is blocked, so employees can also try to go out, in addition to hold an old customer, can also dig cultivate a batch of new customers.

Third, seize the opportunity to network platform, to build brand enterprises in the reform.

Enterprises to network platform, do not represent don't do the counter, don't do physical market. But when entities blocked part of the energy transfer to the network promotion. At the time of economic depression, composed of business won't be agitated, will be more calm, good internal strength. Is so, three years of a road, it is high time to develop network marketing. No modes, to start with simple, with the help of a third party platform into the network.

That lean on, happiness that trouble. Road is bound to bring many merchants inconvenience, cause economic losses. Yet in the overall market, the development of the Internet rapidly, the development of science and technology also complying with the trend of The Times. If a road can make electronic industry transformation and upgrading, come out from the bottleneck of traditional enterprise, is not necessarily a good thing.

The future of the Surface is a marathon

On February 15, Beijing time, Microsoft said on Thursday that although Surface Pro based on Windows 8 tablets last week by evaluation generally, but since last Saturday on sale in the United States, the needs of this tablet PC has been very stable. Microsoft said, Surface series products are beginning to "off".

Many retail stores were reported, 128 gb version 10.6 -inch tablet Surface Pro's initial inventory has been sold out, this kind of tablet computer with a stylus, users can buy $100 of additional keyboard at the same time. Surface Pro 64 gb version tablet sells for $899, 128 gb version sells for $999. Reports that Microsoft's retail and retail giant Staples (Staples), stores the first inventory has been sold out. Microsoft did not release tablet sales Numbers and the first batch of inventory Numbers.

Microsoft said in a statement today: "it's our pleasure demands for Surface Pro had done so well. We are now the focus of the goal is to deliver the user has to order as soon as possible the Surface tablet."

AFP, Microsoft Surface RT tablet sales at m in the fourth quarter last year; By comparison, apple released the iPad in the first weekend of sales to reach 3 million units. Microsoft has yet to Surface RT sales Numbers to confirm; The company CEO Steve Ballmer (Steve Ballmer told French newspaper Le Parisien, "an interview with the sales performance" moderately ", but then Microsoft clarified, Ballmer refers to the company in improving Surface RT supply and distribution, etc.

professionals

Microsoft said in a statement: "although the () in aspects of supply and distribution performance is measurable, but ballmer noted that the market for this kind of equipment acceptance 'excellent', that is what he said: 'not long after, the device will be available in more countries and more store.'" in addition, although the Surface Pro battery life and the thickness of the people, but Microsoft said that social media and consumer response of this kind of product is good, especially the professionals.

Panos, general manager of Microsoft Surface, nai (Panos Panay) told ABC News in an interview: "we focus on the professional market and users often have business trip. Surface Pro is the targeted customer for business travel professionals, they travel constantly, but no matter how to also don't want to compromise in terms of performance." He pointed out that Surface Pro more should be seen as a laptop, not tablets; At the same time, Surface RT is more like a tablet.

Unlike Surface Pro, Surface RT retails for $499, its processor with low energy consumption, based on Windows RT operating system is running, the system can not run the older version of Windows applications. Mr Nye pointed out: "our priority is to produce a kind of professionals that can be used to do all the things of the PC, and when you want to put it into the tablet also can do it. When we want to use Surface RT to create a good tablet experience, and Surface Pro is to let users can do more things or work."

But the problem is, why Microsoft doesn't directly the development of a notebook? Planning and PC ecosystem of Microsoft vice President Michael Angelo (Mike Angiulo) said: "we just think at the beginning of the construction of Windows 8, what others can't launch? Notebook product of this shape factor already exists, and we will produce together with partners in this product."

Future plans

Surface tablet is Microsoft to launch its first PC in the past dozens of years, the company has set up a file in the Surface hardware manufacturing and r&d facilities invested a lot of money. Ballmer said that the company will introduce other products similar to the Surface, but did not disclose details.

Multiple web site there are rumors that science and technology, Microsoft plans to release more Surface products this year, one is Surface the Book, the screen will be bigger than existing tablets.

When asked about notebook and Surface brand, Mr Nye didn't comment for future product plans, but said it see it as a "marathon", not "sprint". He said: "(Surface Pro) this product over a period of time can be used by consumers, which for us is a marathon, we are excited about the outlook for short term and long term."

Intel or production 10 nm process chip in Israel

Intel subsidiary of Israel in 2012 export volume doubled to $4.6 billion, the company is seeking to put Intel's next-generation chip production in Israel.

Intel Israel subsidiary of exports to $2011 in 2.2 billion, and in 2012 year-on-year growth rate of 109%. This is mainly due to the southern Israel buffalo (Kiryat Gat) 22 nm process line began production factory, currently maintains 100% of its capacity.

Intel is the world's number one chip manufacturers, the company will be in Ireland and the United States within the next two to three years of factory introduction of nanotechnology, and begin to consider developing ten nanotechnology. Intel company executives said that Israel wants to 10 nm technology is introduced into Israel's factory.

Intel company general manager, Maxine method, Israel's (Maxine Fassberg) said: "a technology lived to an average of 2 to 6 years, so we need to get the next generation of 10 nanotechnology. We need to have decision-making, so as to upgrade Israel factory. For 10 nanotechnology, relevant decisions will be made this year."

Method as, say, relative to the construction of new factories, upgrading of Israel's 28 nm process line only need less investment, but investment will reach billions of dollars. In terms of cost, Intel company past government subsidies to Israel. Method, and the company continues to discuss with the government.

In Israel in the past 10 years, Intel's investment of $10.5 billion, including $2012 in 1.1 billion, also received $1.3 billion in government subsidies. Last year, in Israel's high-tech industry in the total export, Intel Israeli companies accounted for 20%. And in not including diamond industry in the total export, the company accounted for 10%. Intel Israel company President jose, Eden (Mooly Eden), said: "if Intel does not increase exports, Israel's high-tech industry exports will be reduced 10%."

Intel company in Israel most of the exports, that is, $3.5 billion, from chip making activities. Intel is now Israel's largest private employer, with 8542 employees, a 10% increase over 2011. The company has two factories in Israel, in Jerusalem and buffalo, New York, and there are four research centers.

2013 10 major trend of development of the intelligent terminal

Thu, 14 Mar 2013 06:17:06 +0000

2013 10 major trend of development of the intelligent terminal

In 2013, in a rapidly changing science and technology industry, already a long time or many market talk about emerging industry development trend of if it is possible to implement this year?

TrendForce think global market research institutions, since late last year whether TV, smartphone, or tablet computer, from the brand company launched the product trend, it is not difficult to find that form the two stock markets cyclone, an upgrade for specifications, one is common price, so 2013 will be the generation of intelligent terminal schools of thought contend, detonated software services will further business opportunities.

A bezel, TV size bigger, more narrow

In 2013 years, predictable digital LCD TVS sold on the market size will increase further, according to the survey data of TrendForce, according to a panel shipment the average size of 40 inches to have the opportunity to break in the second quarter, more than 50 inches (60 inches) models of visibility in the market will continue to big, from 6 ~ 8% to 12% in 2012, the terminal retail price also is expected to fall further, but it is not big size TV overnight become the largest commodity in market share, main is every family doesn't have enough space can put so big size machine, but in space allows and price level under the incentive of procurement will inevitably increase the risk of big size TV.

2, the LED in LCD TV permeability to rise again

Using LED backlight LCD TV module, the proportion of the increase was the market trend, permeability will be estimated 2013 at 90%, that is to say, want to find on the market use lamp (CCFL) as the backlight source of liquid crystal TV ratio is relatively low, this makes "LED TV" propaganda use it appears there is no need to. As for OLED TV permeability remains limited, accounting for only 0.2% of the overall market, forecast to only 1.15% in 2015, is still hard to compared with the LED.

3, 4 k ultra high resolution slightly increased visibility

Cooperate with TV size gets bigger, under the trend of 4 k (3840 x 2160 pixel, vertical level about 4 k2k) than the FHD (1920 x 1080) provide a times the high resolution would be overtaken by market discussion, although it might seem glamorous to 4 k, but in terms of reality, the high cost of the panels and the problem of poor ratings, the thesis and its popularization rate is still too early, like market noisy uproar in 2012 3 d TV, highbrow, but manufacturers will continuously introduce about 4 k specification, but is more telling is heavier, there is distance away from the goal of common.

Have four, touch panel PC has its limitation

Though since smartphones introduced into capacitive touch panel, on personal computers, notebook computers and use the touch panel control mode becomes the market hot discussion, the new Windows 8 more built in this operating mode, also there are some laptops began to adopt, but as a panel with touch module, after using the touch panel laptop than not configured on the touch function model, the price will reach us $150 to $250, the laptop has become increasingly affordable and application software is not mature, or sales should be used in special populations with hobbies take fresh advanced users, from the same popularity with time to spare.

Five, square battery production, the price rise of Ultrabook

Tableland this price on the high side of Ultrabook in 2013 is expected to launch price is plain type, let the price can be cut down to thrust comes from the type of battery production, due to protect this suitable for placement in lithium Polymer ultra-thin fuselage (Li - Polymer) the unit price is high, the traditional cylindrical battery low prices due to the volume too big don't share, in between square battery into mass production, order specifications in the Ultrabook will be listed in succession in 2013. TrendForce forecast 2013 Ultrabook market scale will have the opportunity to break through 30 million, account for 17% of the whole laptop market, adopts the square thin laptop battery overall accounts for 5 ~ 8%.

Six, cheap tablet in the red sea, PC brand factory in battle

Predictable in 2013 tablet computers will continue to grow, year brand size estimate delivery can reach 1.5 million units, in the Amazon, the Nexus 7 type agitation drive tablet parity, in 2013, already can foresee there will be more cheap tablet computer, especially the traditional computer brand companies will have more focus on in this aspect, will use a lower order specification panel to launch price more cheap models, in the first half of the market will be busy very much, if this kind of cheaper models market response is good, Amazon, Google and other companies will inevitably will also cut to the same specifications, under subsidized competition, the traditional computer factory own brand of cheap tablet may find it hard to compete for the market in competition.

Seven, portable device toward the four core processor, the eight core development

Smartphones, tablets, under the demand of computing power, toward the four core, eight core development is inevitable, even on the table of each action arithmetic processor manufacturers, qualcomm, Nvidia, mediatek has launched four core processor, Orion has even launched eight core Exynos5 Octa, although its eight core actual is 4 + 4 core, but also subject sex is dye-in-the-wood. Apple's next generation of processors also is expected to follow up, as for the personal computer giant Intel due to differences in architecture, the Merrifield introduced for dual core version.

Eight smartphone, large size, high resolution ratio increased

Orion Galaxy Note leads, the accident created the Phablet the between tablet PC and mobile phone in a new category, under the market demand, each brand all the launch screen size increase model, in addition to the screen size increase, is also relatively improve resolution, it is worth noting that the Phablet restricted to use ways and habits, and to get the economic effect of panel, the size is not unlimited, 5 inches up and down as the popular choice, 6 inches is too big. And 5 inches, 1080 p has become a kind of use and carrying under considerations of mainstream specifications.

Nine, NFC near field communication began to spread

NFC in fact has been much talk, although applications there are still a lot of development space, 2013 built-in proportion among smartphone will lift, even apple's next generation iPhone may also start using NFC, coupled with the TSM was founded in Taiwan, such as micropayments applications will be more popular.

Ten, wireless charging enters the practical category

Although wireless charging is not new technology, but to do power with fast charging still has the difficulty, the wireless charging of mobile devices the current high visibility has 3 kinds, each have their advantages are incompatible, but under a period of brewing, is also a more relevant wireless charging products in 2013.

Thu, 14 Mar 2013 06:15:12 +0000

2012 domestic panel ten percent global market share

Ten years grinding sword, domestic enterprises in the global panel market has a place finally. According to the latest figures, 2012 domestic panel company global market share of more than 10%.

Recently, the ministry released data show that this year, China's large size panel factory panel (7 inches and above) accounted for 11% of global market share, shipments of 76 million piece, its self-sufficiency rate of domestic TV panels supply above 20%, shipments of 670.9% year-on-year growth. Panel in 2013 the expansion of the enterprise will speed up to 2013, Chinese panel makers in the tablet panel global market share of 10.7%, shipments increased 324.5%; TV panel shipments will increase 49.6%, year-on-year 16.2% global market share.

Reported that 2013 countries will focus on support the development of domestic panel company on the OLED technology, three to five years will be China's enterprises to develop into the first three of the leading enterprises around the world. But the personage inside course of study thinks, the current domestic enterprise also faces large size panel rate is low, the production problems, poor ability to pay attention to the research and development of core technology in the future.

Forecast of 2013 smartphones: Microsoft blackberry strong performances

Market Research firm ABI Research, according to the latest report released by the end of 2013, the global smartphone ownership will reach 1.4 billion units. Among them, 57% will use Android system, 21% will adopt iOS system.

Tablets, meanwhile, the ownership will reach 268 million units, 62% for the iPad, 28% for Android tablet. In 2013, smartphone and tablet ownership of year-on-year growth rate will reach 44% and 44% respectively.

ABI Research forecasts that though both apple and Google in the mobile device market strong, but are less likely to appear the situation of duopoly market future. ABI Research, a senior analyst at the distribution, canning (Aapo Markkanen) said: "2013 will be a year to the success of Microsoft and blackberry relative. By the end of this year, we expect the Windows Phone ownership will be for 45 million units, blackberry mobile Phone ownership of 10 will be close to 20 million units. In addition to using Windows tablet will reach 5.5 million units." ABI Research focused on the active equipment used, this is a meaningful market for application developers.

Horse canning also said: "Microsoft and blackberry's biggest fear was that their smartphone initially disappointing sales, leading to the developer to lose interest. This will make them lose the chance of success in the future. We believe that the ownership has been enough to ensure that the Windows Phone and blackberry to participate in the competition. This will also help maintain developers interested in two companies, at the same time, design and introduce their platform."

Scientists invented never freezes the computer, can repair itself

Thu, 14 Mar 2013 06:05:44 +0000

Scientists invented never freezes the computer, can repair itself

In daily life, many people will face computer crashes, blue screen, etc. An annoying things. To solve this problem, scientists in Britain have developed a new computer crashes never happening.

Comprehensive, foreign media reported on February 15, this computer is known as a "systemic", developed by scientists at university college London. It is different from our daily use of computer, the working principle of traditional computer mainly using the data in the memory, the data first came to work, and then the data is stored into the memory. This process usually should follow a fixed program, if there is an error, then the computer will appear problem, lead to crash.

Unlike conventional computers, "systemic" computer data and the corresponding instructions join together, and will be split into different data entity as a result, the scientists described it as "system". Each "systems" have a contain relevant data storage, which means that the system only interact with other similar systems.

Computer scientists at university college London, said Peter bentley "sometimes look your computer to run multiple applications at the same time, in fact, it has failed to do so, it is only used for switching between programs quickly", and "system" of new computer can execute multiple instructions at the same time.

And to the point, "systemic" computer contains numerous copy of the instruction system, if a system crash damage, computer can access another sound system to repair a copy of the code, and ensure the normal order of the tasks executed, won't appear crash phenomenon.

In April this year, Peter bentley will travel to Singapore to attend an international conference, the people will learn more details of "systemic" computer.

Solar photovoltaic (pv) in 2012 the lowest growth rate increase only 5% for 10 years

Thu, 14 Mar 2013 05:57:36 +0000

Solar photovoltaic (pv) in 2012 the lowest growth rate increase only 5% for 10 years

According to the NPD Solarbuzz Marketbuzz pointed out that global solar pv demand of 29.0 GW in 2012, from 27.7 GW in 2011 grew only 5%, less than 10% for the first time since ten years ago.

"At the beginning of the 2012 and 2013, industries are in total 2012 pv demand is expected to more than 30 gw level," NPD Solarbuzz senior analyst Michael Barker says, "2012 pv companies on demand is often more than 35 gigawatts (gw), hope to see improvement in the imbalance of supply and demand and the profit level quick recovery etc signs of improvement, but the final demand is only less than 30 gigawatts (gw)."

Cut solar subsidies, despite more than 2012 countries in Europe is still the largest regional market, the total demand for 16.48 gigawatts (GW), accounting for almost 60% of global market share, but down from 68% in 2011 and 82% in 2010. Asia as the second largest photovoltaic market, the total demand for 8.69 gigawatts (GW), in which the terminal market in the second half of 2012, China's rapid growth is an important driving factor.

American pv market demand is divided into North America (USA and Canada), and Latin America and the Caribbean, in 2012 the American pv demand for 3.68 gigawatts (GW), accounting for 13% of the global total, much of it comes from California. Thanks to a renewable energy quota standards (RPS) and subsidies, the California market demand in 2012 accounts for more than a third of the whole of the americas.

Although pv demand failed to break through the 30 gw in 2012, but still create the new record annual demand, including the installation of nearly 30% from the end of 2012. But in 29.0 GW of the level of demand and the upstream manufacturers supply level there are still gaps.

"Such as the 2012 market to reach equilibrium of supply and demand, then the end market demand should be close to 45 gw level," added Barker, "this is 50% more than the actual demand, elasticity of demand reflects the current industry lack of problem, also explain why the win market share in 2012, the company also can appear larger operating loss."

NPD Solarbuzz forecast 2013 photovoltaic industry will accelerate the globalization, Latin America, the Middle East and Africa, demand from emerging regions such as Asia Pacific market will continue to grow. But also many uncertainties exist, these areas will affect the speed of renewable energy applications and ultimate size pv market in 2013.

"Emerging area in 2013 is very important to the whole photovoltaic industry supply and demand balance, and will become the industry when demand is the important factor of over 30 gigawatts (gw) years." Barker said at last.

The difference between circuit board (PCB) Shen gold and gold-plated plate

Wed, 13 Mar 2013 09:51:55 +0000

The difference between circuit board (PCB) Shen gold and gold-plated plate

I met a lot of customers do not know the difference between Immersion Gold PCB with gold-plated PCB. PCB board do immersion gold gilded plates are common circuit board technology. It is often said are gold, above this will affect the functionality of the circuit board? Let's concerned about the difference between.

IC foot more and more in today's increasingly superb technical capabilities, the more intensive HASL process is difficult to fine-foot pad blown flat, which brought a degree of difficulty to the welding SMT placement, another HASL the board's stand-life shorter PCB made of gold-plated board just to solve these problems, played a decisive role in the quality of paste board for ultra-small, such as 0603 and 0402 the surface, so the entire board gold plated high-precision and ultra-compact chip technology is relatively common. Good PCB board in the sample stage, components procurement cycle, generally have to wait for some time, but the sample cost than HASL or less, so we chose a gold-plated, what is gold-plated, we are talking about The entire board gold-plated, generally refers to "gold plating" electroless nickel gold plate the "electrolytic gold" the electric gold "" electroless nickel gold plate, the distinction between soft and hard gold (generally hard gold for gold the finger), the principle is the nickel and gold (commonly known as the gold salt) dissolved in the chemistries of the circuit board is immersed in the plating tank, and turns on the current in a copper foil surface of the circuit board to generate the nickel-gold plating, electroless nickel gold high hardness of the coating, wear-resistant, not easily oxidized advantage has been widely used in electronic products.

What is Immersion Gold? Immersion gold is by chemical oxidation-reduction reaction of the method to generate a layer of coating, generally thicker, is a kind of chemical nickel the Jinjin layer deposition method, can achieve a thicker gold layer

Immersion Gold PCB board with gilded plates distinction

General Shen gold, gold-plated gold thickness is much thicker than gold-plated, immersion gold golden brown over more yellow, look at the surface more satisfied customers Immersion Gold. Both formed crystal structure is not the same.

Not the same crystal structure formed due Shen gold and gold-plated, immersion gold is easier than gold-plated, welded, and not caused by poor welding, causing customer complaints. Also immersion gold than gold-plated soft Goldfinger board general election gilded, hard gold wear.

3, Shen gold plate only on the pad with nickel and gold, the skin effect in the signal transmission in the copper layer will not affect the signal.

Immersion Gold crystal structure compared with the gold-plated, denser, less production costs oxidation.

As more and more dense wiring, line width, spacing, has come to the 3-4MIL. Gilded is easy to produce the Watkins short circuit. Immersion Gold board only pads nickel gold, gold wire production costs so it will not short-circuit.

6, Immersion Gold board only pads nickel gold, solder mask on the line with the combination of the copper layer is more firmly. Works for compensation will not have an impact on the pitch.

Generally for relatively higher board flatness is better, generally Immersion Gold, Immersion Gold generally does not appear the assembled black pad phenomenon. Immersion Gold board flat and stand life with gold plating as good.

After then, the general factory do not want to do gold plate and gold plate the entire board should be gold-plated, but we all know the price of gold is very expensive, Immersion Gold only nickel gold pads from economic cost-effective some

PCB circuit board to pay attention to the puzzle problem in switching power supply
Sources of information: PCB circuit board in this article Keywords: board circuit board pcb board; PCB FPC flexible printed circuit board
-------------------------------------------------- ------------------------------

Do the switching power supply board circuit board, you need to pay attention to the problem:

1) AC power into the line, two-line fuse before the minimum safe distance of not less than 6MM, the two line within the cabinet or machine ground is not less than the minimum safe distance 8MM.
2) Fuse traces requirements: zero, the FireWire minimum creepage distance not less than 3MM.
3) high-pressure area and the area of low pressure minimum creepage distance not less than 8MM insufficient 8MM or equal 8MM. Shall be open the 2MM security slot.
4) screen printing of high voltage warning identifies high-pressure zone that exclamation mark triangle symbol; live in the high-pressure zone with silk screen box, Moulding silk screen shall be not less than 3MM wide.
5) the minimum safe distance between the positive and negative high voltage rectifier is not less than 2MM

A Y capacitor how to place

Y capacitor common pitch is 10mm, leaving the pad, the middle of the gap is 8mm, the middle best not trace
Do not go in the middle line, placed of course, is the top and bottom of the plate, left a strong power, the right to the best weak and strong electric side GND GND pins to power, the weak side the GND is best near the transformer
Input ground, there are three Y placed is luxurious
The Y capacitor connected transformer GND terminal according to the "Y capacitor power design reference, then back capacitance I think is the same reason it.

2, leading to high-power, followed two things:
1, the main current loop is best not to use jumper If you must use jumpers need to add sleeve jumper above components needed points gum
2, limited flat area and a safe distance as bold as possible, if you can not bold, you need to add auxiliary solder layer

3, the signal ground and power ground
Take PWM control flyback, to distinguish between the two is actually to the PWM chip from interference, that is, the chips need auxiliary power, the ground terminal of the chip should be connected to the auxiliary power supply filter capacitor, and should not be connected to the large capacitor
Half-bridge or full-bridge and control chip input non-isolated, and that the same flyback isolation (for example, some standby auxiliary power), you should add 1 to 3 0.1uF capacitor on the power supply .

4 input LC filter
Just say here that elaborate for wide voltage 85 ~ 264V switching power supply
1, input the X capacitor package size, because the size of the X capacitors are already standardized, If you need to increase the X capacitor authentication, if the package is small, is very troublesome, so the X capacitor must do in the beginning of the design ready, prefer big points, do not small money can not here and elsewhere Province
2, varistor varistor some without jacket, and belt sheath size to a larger size, so the X capacitor, you need to allow more space
3, L, common mode and differential mode design if you want to differential mode need to verify that for small power generally do not add
4, NTC / PTC, is a negative temperature coefficient, a is a positive temperature coefficient, the role of the two are to prevent the inrush current

Rigid printed circuit boards and flexible printed circuit board design considerations distinction

The flexible printed circuit board design can follow the rigid circuit board design. However, there are other requirements to be noted

1, flexibility

FPC is a standard requirement flexibility, bending radius should be designed to be as large as possible. While the use of thinner plates and the wider wire. This can better increase its exposure to repeated cyclic bending possible. The single-sided flexible circuit board can withstand a large number of bending cycles.

2, the current carrying capacity of the line

Compared with the rigid circuit board, the heat capacity of the flexible printed circuit board to be worse, so we designed wire must provide sufficient width, especially to withstand high-current lines similar, have to consider the heat problem, so we must be more given line width or spacing.

3 pad

In the periphery of the pad, there is a change from a flexible material to a rigid material. This area is easier breakage of the conductor. Therefore, the pad should be avoided in the prone curved area. The general shape of the pad should be like a teardrop, the coating must be able to cover the seam of the pads.

4 of the flexible printed circuit board reinforcement is the enhancement section

Today, some of the small electronic device like the use of soft board, particular plus a soft plate of the reinforcing plate, so that the cost is more optimized. The flexible circuit board can be inserted into the slot the rigid circuit board, for subsequent separation.

5 soft board shape

We generally preferred rectangular in shape, so you can better save the substrate, at the edge of the board to allow sufficient free margins, in shape, generally within the solution made better round than pointed the interior angles of light plate prone to tear-shaped inner solution.

Usually a small line width and spacing is the smallest possible, if space permits, generally dense thin line can be widened, and can be as much as possible the widening, generally through-holes and terminates at line should be a smooth transition to the pad. Soft board, any change from a straight line to the corners or different line widths, we should be a smooth transition, we can see a lot of soft board we spiral traces.

In summary, we can conclude the soft board design with hard board some of the differences:

1) the three-dimensional space of the flexible printed circuit is very important, because the bent and flexible applications can save space and reduce the plate layer.

2) compared with the rigid board, flexible board low tolerance requirements, allowing greater tolerance range.

3) because the wings can be bent, the requirement of the ratio in which they are designed slightly longer.

In order to make the circuit cost reaches the minimum, the following design techniques should be considered:

1) is always to be considered circuit how is assembled on the panel.

2) The circuit should be small, should consider the use of a series of small circuit instead of a large circuit.

3) Whenever you have to follow the recommended use of tolerances.

4) only where necessary design element bonding area.

5) If the circuit is only a small number of layers, using the enhanced rigid flexible printed circuit board comparable much cheaper.

6) per oz of copper-clad material (including electroplating copper), specify the use of 0.0001 in the binder.

7) manufacturing without shelter pads and no covering layer circuit, sometimes more cheaper.

Aluminum circuit board LED expertise
Information sources: This article Keywords: board circuit board pcb board; PCB FPC flexible printed circuit board
-------------------------------------------------- ------------------------------

Aluminum plate because of the high thermal conductivity of aluminum, good heat dissipation, can effectively export the internal heat, the product of choice for LED manufacturers. The aluminum plate is a unique metal-based CCL, with good thermal conductivity, electrical insulation properties and machining performance, we should try to design the PCB near the aluminum base, reduce the thermal resistance of the part of the potting.

The following, I will introduce some of the characteristics of the aluminum plate:

First, the aluminum plate purposes:

Usage: power hybrid IC (HIC).
Audio device: input, output amplifier, balanced amplifier, audio amplifier, preamplifier, power amplifier.
2 Power supply equipment: a switching regulator `DC / AC converter` SW regulator like.
3. Communication electronic equipment: high-frequency amplifier `filtering appliances` transmitter circuit.
Of office automation equipment: motor drive.
Car: electronic regulator `igniter` power controller.
6 computer: CPU board `floppy drive` power supply unit.
The power module: converter `solid relay` rectifier bridges.

Second, the aluminum plate features

1. Using surface mount technology (SMT);
2 in the circuit design, a very effective treatment of thermal diffusion;
3. Reduce product operating temperature, increase power density and reliability, and extend the life of the product;
4. Smaller footprint, lower hardware and assembly costs;
5. Replace the the fragile ceramic substrate, to obtain better mechanical durability.

Third, the structure of the aluminum plate

Aluminum CCL is a metal circuit board material, composed by a copper foil, the thermal insulating layer and the metal substrate, and its structure is divided into three layers:
Cireuitl.Layer line layer: the CCL line equivalent to the ordinary PCB copper foil thickness loz to 10oz.
DiELcctricLayer insulating layer: insulating layer is a thermal insulating material of the layer of low thermal resistance.
BaseLayer grassroots: a metal substrate, typically aluminum or selected copper. Aluminum Copper Clad Laminate and traditional epoxy glass cloth laminated board.

Circuit layers (i.e. the copper foil) are usually formed after etching the printed circuit, so that the various components of the element are connected to each other, under normal circumstances, the circuit layer is required to have a large current carrying capacity, which should use thick copper foil thickness of 35μm ~ 280μm; thermal insulation layer is where the core technology of the aluminum plate, it is usually filled by a special ceramic special polymer, thermal resistance, excellent viscoelastic properties, the ability to heat aging, able to withstand the mechanical and thermal stresses.

The thermal insulating layer of the high performance of the aluminum substrate is the use of such technology, it has extremely excellent thermal conductivity and high strength, electrical insulation properties; metal substrate is an aluminum plate support member required to have a high thermal conductivity, typically an aluminum plate You can also use a copper plate (copper which can provide better thermal conductivity), suitable for drilling, punching and cutting conventional machining. The PCB material compared to the other material incomparable advantages. Power components, surface mount SMT public art. No radiator, greatly reduce the cooling effect is excellent, good insulating properties and mechanical properties.

Need to address the problem of high precision circuit board ultra-the dense thin line production

Need to address the problem of high precision circuit board ultra-the dense thin line production
Information sources: high-precision circuit boards this article Related Keywords: board circuit board pcb board; PCB FPC flexible printed circuit board
-------------------------------------------------- ------------------------------

Modern production, mainly reflected in the development of electronic work, increasing the integration of electronic components, the volume occupied by smaller and smaller, the use of BGA type package, which requires a line on the PCB getting smaller and smaller, more and more layers to reduce the line width to make full use of the limited area, increasing the number of layers, the effective use of space, so that 2 ~ 3mil circuit board is the main stream.

The production process can be divided into the cover the hole etching method and pattern plating method, both have their advantages and disadvantages. Etching on line is very uniform, favor impedance control, less environmental pollution, but there are holes broken, resulting in end-of-life; alkali corrosion control easier to produce, but the line is uneven, environmental pollution.

First, the primary of the line production is dry film, different dry film different resolutions, but in general can be displayed after the exposure 2mil/2mil the line width, the resolution of the normal exposure machine can achieve 2mil Usually in this The line width within the range are not an issue. In the 4mil/4mil the line width from the above developing machine nozzle, pressure, syrup concentration relationship is not following the 3mil/3mil line width, the nozzle is affecting resolution, the general application of fan-shaped nozzle, the pressure in the to developing 3BAR about.

Exposure energy is a very large impact on the line, but in general is currently on the market to use most of the dry film exposure range is quite wide. 12-18 (25 exposure feet] or 7-9 (21 exposed feet) can be distinguished in general exposure low energy point conducive to the resolution but the energy is too low in the dust in the air and a variety of miscellaneous was great impact will result in a subsequent step, the open (acid etching), or short-circuit (alkali etching). Accordingly, when actual production with the degree of cleanliness of the darkroom combination, so selected according to the actual situation can produce circuit boards circuit minimum line width and line spacing.

Developing conditions for the resolution of the more obvious when the line smaller impact. When developing condition (speed, syrup concentration, pressure, etc.) in the line above 4.0mil/4.0mil obvious; line is 2.0mil/2.0/mil ', the shape of the nozzle, the pressure for developing a line normal play key The role of developing speed at this time may be significantly decreased, while the concentration of the syrup is influential on the line appearance, the possible reason is that the pressure of the fan nozzle, in the case of small line spacing, momentum can achieve dry film bottom, therefore may be developing; small conical nozzle pressure and therefore have difficulty developing fine line. Put them in the direction of the plate has a significant impact on the resolution and the dry film sidewall.

Different exposure resolution. Exposure machine currently used one is air-cooled, the surface light source, and the other is a water-cooled, point light source. The nominal resolution are 4mil. However, the experiments show that having to do special adjustment or operation can be done 3.0mil/3.0mil; can even do 0.2mil/0.2/mil; the energy decreases 1.5mil/1.5mil can also be distinguished, but then the operation should be carefully, and the effects of dust and debris. In addition, the resolution is not a clear distinction of the Mylar surface and a glass surface in the experiment.

For alkaline etching, plating after there is always a mushroom effect, generally only apparent and obvious distinction. Such as line greater than 4.0mil/4.0mil, mushrooms with smaller effects.

When the line is 2.0mil/2.0mil very large impact on the dry film plating pewter overflow formation of mushroom-shaped dry film is sandwiched inside Stripping very difficult. The solve methods; 1. Pulse plating so that uniform coating; 2. Use a thicker dry film, dry film in general is 50-55 microns to 35-38 microns thick dry film, the high cost of some such dry film is better used in etching; 3 with low current plating. However, these methods are not thorough. Actually difficult to have a very complete way.

The very troublesome mushroom effect, fine lines Stripping. Can Because sodium hydroxide pewter corrosion will be very obvious in 2.0mil/2.0mil so plating thicker pewter and reduce the concentration of sodium hydroxide to solve.

When alkali corrosion different width at different speeds and the lines different shapes at different speeds, if the circuit board has no special requirements in terms of the thickness of the lines produced using 0.25oz a copper foil thickness of the circuit board production, or 0.5oz base part of the copper etched thin copper plating, pewter thickened all line with alkali corrosion and meticulous work to another nozzle required fan. The conical nozzle general can do 4.0mil/4.0mil.

Etched with an alkali in the etching when the same is different from the shape of the line width and line speed, but generally with the etching when the dry film is easy in the transmission and in front of the step will aperture of the membrane and the surface of the membrane torn or scratched , so production need to be careful with to etching its line effect than alkali eclipse better mushroom effect there is no lateral erosion than the alkaline etching, the other with a fan-shaped nozzle effect is significantly better than the conical nozzle. Etching after the impedance of the line changes.

In the production process, the speed of the temperature of the foil the plate surface cleanliness, diazonium sheet cleanliness pass rate greater impact parameters and the plate surface of the formation of the etching foil is particularly important; on the alkaline etching, the exposed cleaning is important.

So that: ordinary equipment not specifically adjusted to achieve production 3.0mil/3.0mil (the film line width, spacing) board; However, the pass rate is influenced by the environment and proficiency of personnel to operate and operating levels, alkaline etching suitable production 3.0mil/3.0mil following circuit board, unless the base copper is small to a certain extent, the effect of fan nozzle was significantly better in the conical nozzle.

It should be noted that the problem in the circuit design, PCB / FPC

Wed, 13 Mar 2013 07:36:53 +0000

First, the design of the circuit board pad, be careful not to overlap.
1, Usually the pads are provided with holes, generally pads overlap addition SMT pad, it will cause the overlapping of the holes and the hole once overlapped, the drilling machine will normally be several times over the course of a drilling This guide to the broken drill bits, which will damage the hole.

2, the above is a single sided, if made of plywood, two holes overlap, such as a hole in the Land (flower pad), another hole for the isolation plate, two holes out of the film after isolation disk will cause scrapped.

Above, we design a circuit board files must be careful not to overlap the hole is pad.

Second, pay attention to design do not abuse the line layer

1, the general design software has said level, was the only line of double-sided, indeed in the inner layer more useless lines, or a four-layer board, come up with five lines (some lines is useless). So easily misunderstood. Please note that in this respect.

2, and sometimes our designers also breaching conventional design BOTTOM surface component side, the welding surface design to TOP.

Third, do not misplacing characters

1, if the characters cover the pad SMD give off printed circuit board testing and welding inconvenience.
2, there is little character design is too small, printed more difficult, too big and make the characters overlap illegible.

The IV filled the block copper or painting line acts as a pad, we need to manually draw the corresponding solder mask data.
Filled the block copper or painting line to act as a pad by the DRC check, but in the corresponding layer is not automatic production solder mask data, so that the pad will not open the window, welding regional conference solder mask oil layer to the device welding difficult, it is recommended that we want to avoid this situation, it is this case, we need to draw the corresponding solder mask data manually.

Processing level definition is not clear

, Especially single panel, some people will line design in the TOP layer, it was designed in the the BOT layer (conventional, general BOTTOM layer), in which case we generally need to be explained. Or easy to do wrong.
2, there generally we do a multi-layer circuit board, there is a layer of the order of, for example, a four-layer board design using the TOP in1 in2 bottom four, but we are processing, if you do not order this, you need a system board Description indicate.

Seven, do not design a circuit board files do not use a very fine line to fill many blocks.
1, such as a file in the large-scale use thinned filler block, easy production of the light will be data loss.
2, due to the file thin line, thereby increasing the amount of data, so that the file data, and to increase the speed of data processing.

Eight, and try not to pad surface mount devices designed too short

This is mainly energy off test, too dense surface mount devices, their spacing is very small, the pad is also fine to arrange testing needle, up and down the staggered position (left and right), if the pad is too short, rendezvous test needle wrong not open a bit difficult, resulting in test.

IX a large area of the grid spacing design is too small

Composed of a large area of the grid lines with the line between the edge is too small (less than 0.25mm) Figure transfer process is prone to significant shadow after a lot of broken membrane attached to the board in the PCB manufacturing process, resulting in disconnection .

10, designed not to a large area of the circuit board copper foil from the frame too close.

Copper foil from the outline of a large area should at least ensure that the spacing of 0.2mm or more likely to cause copper foil milling shape, such as milling the copper foil Qiqiao and arising out of the solder resist shedding problems exposed copper.

XI frame to design clear

Many customers will be guilty of this case, some customers keep layer, said some top over layer, some mechanical layer, but some of these layers are drawn, but do not overlap, so that we The circuit board manufacturer is difficult to judge which lines prevail.

XII large copper on the general board, we try to use the grid lines, so good to avoid SMT soldering copper blister.

PCB original LiaoChang weaker orders in March have difficulty increases

Compared with 1, 2 month is warm market scenario, PCB raw material industry in March showed signs of weaker orders status, especially in late march the market is quite unclear. Glass fiber yarn, who think, in the case of long-short is unknown, in March have difficulty is going to rise. In addition, the copper foil substrate industry also said that since this year, has launched two prices, from the perspective in the latest quotation, equal probability is bigger.

Recently, the international copper prices remain at $9800 / tons near the high-grade, copper foil substrates factory since this year, has successfully launched two price increases, price increase in January and February, respectively implement the deferred until February, march.

About the movements of the latest quotation in March, copper foil substrates operator said, from the perspective of the market conditions of march, there seems to be no 1, 2 month to warm, also worry that the second quarter next five poor, six of the off-season effect, so don't want to active at this time to establish the upstream material of glass fiber cloth inventory levels.

Copper foil substrates operator said, from the latest quoted price trends, no change, in principle, should be a flat last month, gains a little sleep, still need to have more order, again to a new wave of rally.

Dehong fiberglass gauze factory (5475), Joe (1815) for march's view is different, dehong relatively optimistic, think the march will be able to continue to increase. Rich Joe is more conservative, in late march and said after the market is not clear, the touch of long-short market factors, although the overall market inventory level is low, but if the customer don't place the order, even if the price increases also does not make sense.

Microsoft Windows 8 tablets or will be launched at the end of the year

News that Microsoft is developing Windows 8 tablets, plan released late this year.

Despite Microsoft's Windows 7 doesn't stimulate tablet sales, but now there are many tablets by using this system, such as dell, HP and LG tablet. Microsoft is preparing to modify Windows, so it is more suitable for flat.

Microsoft announced at CES in January this year, Windows 8 will be the first supporting ARM processor, this means that Windows 8 will be applied to tablets and other mobile devices. Now Microsoft has ordered nearly 1000 engineers, development of Windows 8 for touch screen.

Morgan Stanley analyst Adam holt said in a report Friday, support for Windows 8 of ARM chips, as will be finished at the end of the year or early 2012 to develop, this means that the launch date of Windows tablets may be earlier than the expected.

Holt said Holt (Adam), Microsoft Windows 8, hinted that it will be 2011 tablet is quite important battle for dominance, Microsoft did not touch the device completely give up.

Holt said that Microsoft is considering offering $100 in equipment. He says that when apple is deployed the iPad, the enterprise often use the virtual desktop for Windows and Windows programs, Microsoft is considering this way to provide $100 in equipment.

Holt said that even if apple dominate the tablet market, Microsoft is still can be obtained from using the iPad business revenue. Because enterprise after deploying the iPad, still need through the virtual desktop to run Windows and Windows applications.

Wed, 13 Mar 2013 03:45:09 +0000

3 g version of the iPad has fallen gray hundred WIFI version of the lowest 3500 yuan

The iPad "gray" prices have eased. Reporters yesterday visited the computer stores, found that in the size of the 3 g 16 g version of the iPad, for example, used 4700 yuan to 4800 yuan price is history, 4300 yuan to 4500 yuan to become common offer range, "because supply came up, another reason is the Spring Festival, bought gifts less." A number of merchants told reporters.

Prices reflect the first on the Internet. These days, in taobao search 16 g 3 g version of the iPad, the size of its offer almost all concentrated in the 4200 yuan to 4300 yuan, more than 4800 yuan is very little. Yesterday, the reporter also found in the Broadway chaowai street, merchants are the quoted price from 4200 yuan to 4600 yuan, but, no matter how much offer all the merchant asked admitted that 3 g version of the iPad's price cut.

"In fact the price from the first began." Merchant Mr. Ma told reporters. "but before Spring Festival many units choose to iPad as prizes, relatives and friends some people also choose this as a gift, so the price is not obvious at the time." Decreased after the Spring Festival, as gift economy climax, the iPad price is falling, the size 16 gb WIFI iPad offer more concentrated in the 3500 yuan to 3700 yuan, and the 3 g version of the iPad "gray" hundred yuan has fallen.

"I don't think the iPad is already too big price cut space." Merchants to Mr And ms Chen Yin said. They have learned that the iPad 2 forthcoming news, "according to apple's consistent policy, the second generation listed after the generation of product production will gradually drop controlled at most." Ms Chen says.

Yesterday, apple has formal conference invitation issued iPad 2 products, this means that people experience the iPad but just more than a year, it will face new temptations. According to previously released technology enthusiasts, iPad 2 products more thin, on the model display higher resolution, set up a dual cameras before and after, still can run at the same time two telecommunications GSM and CDMA network. "Gray market then certainly is a new high tide." Merchants, Mr Ma said, "every time like this."

In 2014 our country digital television market scale will reach 500 billion yuan

Wed, 13 Mar 2013 03:39:32 +0000

In 2014 our country digital television market scale will reach 500 billion yuan

Digital TV accounted for more than half, the layout is basically completed, however, the existing layout of unbalanced shows a lot of business opportunities. In the next 10 years, the rapid development of digital TV and industrial chain driven by huge market value.

The sixth plenary session of the 17th communist party congress passed "the central committee of the communist party of China to further the reform of cultural system to promote great development of socialist culture prosperity of several major issue decision" points out that the development of modern communication system, improve the radial force and influence of socialist advanced culture, must speed up the construction of advanced technology, fast communication and wide coverage of modern communications system ", and "cultural enterprises of strength are encouraged to cross-regional, cross-trade and cross ownership merger and restructuring, fostering cultural industry strategic investors".

At the same time, according to the triple play policy we found that the three nets fusion of radio and television system path will go through three important stages: 2010 ~ 2011 competition preparation. Stage of the industry growth driving force mainly comes from the cable TV users of monkey enclosure movement, namely the development of the industry fully enjoying the cable digital TV conversion bring user growth dividend; Competition law from 2012 to 2015, the "whole subnetted" phase of the driving force comes from the depth of the user's operating, especially to the living room culture and entertainment of the tap; Open competition in the period after 2016. "Three subnetted" phase of the driving forces from all business operations, and integration of industrial chain ability to ascend. Exactly on the three nets fusion of 2012 strategic stage period on the steps, began to prepare for market development.

From 2003 to 2003, our country digital television market scale will expand from 40 billion yuan to 40 billion yuan, the scale of the entire digital TV industry in China in 2011 is expected to more than one trillion yuan, the market potential is immense. In the next 10 years, China's digital TV will get rapid development, the market value of the industrial chain it will bigger.

The development of China's industry is inseparable from the policy support, on November 1, 2011, as a "national terrestrial digital TV standard" the standard of form a complete set of the terrestrial digital TV terminal receiver general specification (device) ", formally implemented, China's production and sales of all digital TV terrestrial digital TV receiver function is a must. This for many IC company and hd industry, is definitely a good news.

On the other hand, users of the popularity of digital TV is also very high. According to norda consultation according to the survey: 98% of users show wants to use instant communication terminal based on TV products, 76% of users said will use instant communication terminal based on TV products, 22% of users said not sure can use instant communication terminal based on TV products, only 2% of users said sure not use instant communication products. Because the user preference for the instant messaging product terminal TV at home is second only to the computer, and higher than mobile phones. TV penetration rate is far higher than that of mobile phones and computers. Under the condition of the three nets fusion development based on TV terminal of instant communication tools possible.

In addition, the future potential. 408 million TV users in China, so far there are 275 million cable subscribers, and direct broadcast satellite coverage of 13.5 million users, to remove these users, there are nearly 200 million users rely on the ground wireless TV to watch TV. So potential in the future market space is very large, it will fully erupted after three nets fusion.

Although TV digital development has begun to take shape, but its distribution is very unbalance, from absolute, part of the province development to digital television users "must" level. Three provinces of zhejiang, guangdong and jiangsu cable digital TV users are more than 10 million units, of the cable digital TV overall market share of around 27%.

From digitized degree is also a picture of the cable TV development slower province implements one pace reachs the designated position, qinghai, xinjiang, ningxia, Inner Mongolia, and guizhou provinces digital proportion more than 70%, the qinghai province digital rate as high as 96%.

Combined with total digital development mode, and the most potential to sichuan, henan, jiangxi province. First of all, the region has a huge user base cable TV, secondly, its digital degree were not beyond 30%, cable transfer digital market potential is enormous; Shandong, jiangsu, guangdong, zhejiang and hubei province base centered digital degree, there are certain development space, can tap its potential mainly embodies in the rest of the cable digital TV conversion; And cable TV development is relatively slow of qinghai, xinjiang, Inner Mongolia and other places due to a one-off development mode with its rapid economic development in recent years, the digital television layout is even better than developed regions. Beyond the above three areas, the development of the rest of the power is slightly less than that of cable TV is still in development, digital consciousness is not strong, so they are not classified as potential area.

Apple's foray into the enterprise market: ge employs Mac instead of PC

Wed, 13 Mar 2013 03:01:05 +0000

Apple's foray into the enterprise market: ge employs Mac instead of PC

Beijing time on 18 January evening news, general electric has recently launched a test plan, allow employees to use the apple Mac computer replace Windows PC. , analysts say the move will help it expand the enterprise market share.

Test plan according to a period of one year, ge employees now can choose apple Mac laptop or a desktop, to replace Windows PC. Currently has about 1000 ge employees use a Mac computer, when more and more employees know the test plan, believe this number will continue to rise.

Apple computer in the enterprise market share is small, but the situation is improving. Research firm Forrester (microblogging) Research predicts that this year, apple will enterprise users sold $9 billion worth of Mac computers and iPad for $10 billion, year-on-year growth of about 50%. At the same time, the enterprise users at other computers and tablets will spending fell 3% to $69 billion.

Threat to the traditional PC makers

Apple, analysts have said into the enterprise market, and support from the business of ge such size, for dell (weibo) and a traditional PC manufacturers such as lenovo is a big pressure. As in the smartphone market, apple has now pose a threat to traditional smartphone manufacturers such as research in motion (RIM).

Ge began to allow employees to use apple's iPhone in 2008, as the RIM blackberry (microblogging) mobile phone replacement. Today about 10000 ge employees use iPhone, blackberry 50000 use.

At present, general electric did not formally announced that allow employees to use Mac computer, therefore many employees don't know about this test plan. General electric's chief technology officer Greg Simpson (Greg Simpson) said: "in providing employees with this option, all companies will be tested to some extent."

Apple, according to Gartner and IDC, the current is America's third largest PC manufacturers, the market share of 11%. Ranking the first place, by contrast, HP (microblogging) PC market share of 23%. Apple computer in the enterprise market share is small, less than 1%, and HP, dell and lenovo are around 25%.

For apple to the enterprise market development, director of HP business PCS Carol hayes (Carol Hess) said, attention has been paid to the problem. Hayes says: "we are also developing enterprise market, but I'm not sure, like apple's product is suitable for enterprise user."

Compatibility is the obstacle factors

Boston Scientific Corporation (Boston Scientific Corporation), chief information officer, west (Rich Adduci) think that cost and compatibility is still the apple into the enterprise market obstacles. Freddy adu west said: "apple's product is really good, but compatibility problem is a challenge."

But the iPad is an exception. IPad, Boston scientific cooperation with apple, using iPad for sales. At present, Boston scientific corporation has purchased 4500 ipads. The end of this year, Boston scientific corporation plans to switch to iPad.

General electric's chief technology officer Simpson also pointed out that the Mac computer's price and the price of PC is shrinking, the Macbook starting price of $999, while the other vendor's ultra-thin, ultra-light laptops price is between $899 and $1400.

At the beginning of this month's annual summit, electricity electric 600 senior executives people an iPad. For this test plan, Simpson says: "this question involves a learning curve, we know that the original may not particularly perfect. With the growing demand for staff, the test plan will continue to expand."

LED industry merger integration PCB

Wed, 13 Mar 2013 02:57:42 +0000

Since this year, following the vision perfect photoelectric photoelectric, big eyes light, led display, etc. A group of hundreds of millions of scale enterprises have collapsed, and hundreds of millions of jia hao photoelectric enterprise unpaid suppliers were seized $18 million payment for goods. Close to year end, and when the overdue payment for goods, some small and medium-sized enterprise capital chain tension, until year end payment arrears or upstream suppliers, are more likely to borrow usury, the boss run, even the phenomenon such as collapse of bankruptcy.

And the main cause of capital chain rupture is overcapacity and falling prices, margins are slim. This phenomenon not only appear in the small and medium-sized enterprises, have appeared in many listed companies led the trend of sharp decline in profits.

According to statistics, 25 led key listed companies, this year's revenue in the third quarter year-on-year growth has 15, accounting for 60% of the total, decreased by 10.83% in the first half; Net profit year-on-year growth of only 10, 40% of the total. Above 25 listed companies, the performance decline is more serious for the upstream and downstream screen application enterprise chip.

According to the national semiconductor lighting project research and development and industry association (csa) statistics, the current domestic led epitaxial chips more than 60 enterprises, has been in place of the mocvd equipment number about 1000, has become a mocvd machine is used the largest number of regions. But because of the debugging process, technology, personnel, patent and market demand, the upstream production has not fully released, according to incomplete statistics, the capacity utilization (utilization) of epitaxy chip enterprises only around 50%.

Merger integration "means" to keep warm

In this market tussle for "breakthrough", each enterprise is a "sea situation". Actively open up channels and application expansion of capital markets, ipo, major market segments, differentiate themselves to play fast break into a price war, there are a lot of enterprises to choose a more direct way of "bulk", namely the merger integration.

May withstand the ordeal "market" to live in the companies, some of the suffering. But we need to realize that the development of an industry, especially in emerging industries, to consider the industry law of development, problems, and calm at the led industry only after sufficient competition to achieve a merger, acquisition and reorganization, to achieve superior bad discard. As combined radical throws the President LiuJianYun, m&a is only a tool, often occurs in the enterprise growth, took place in the industry is increasingly fierce, occurred in the process of resource matching, m&a is a very normal phenomenon.

And the excess production capacity, investment overheating, the status of the price decline, falling profits just for led industry a fully competitive environment, from the current industrial development, both on middle and lower reaches of vertical integration and horizontal merger integration, has appeared in the industry and gradually into a trend, in the led industry reshuffle is accelerating.

Taiwan's second-largest epitaxial factory ladies round with the mainland's largest led chip factory three Ann photoelectric contract, combined with previous broadly gallium and crystal electric, ronda cooperation with power fierce led industry merger integration trend intensified.

Overall, passive or active m&a integration between enterprises is the trend of The Times, the strong stronger. According to csaconsulting statistics, from the perspective of the scale of enterprises, in 2012, the number of output value over 100 million yuan rose 13%, the backbone of the semiconductor lighting industry development increased, is conducive to the sustainable development of the semiconductor lighting industry.

On the one hand, the led industry profiteering era has gone, the face of industry profits fell sharply, through the form of expansion, integration, mergers and acquisitions, strategic alliances can achieve economies of scale, reduce production cost, therefore, the first choice for many enterprises. On the other hand, a strong competition in the face of international companies, merger integration can be found in patent, technology, market access sharing advantages, mutual resist challenge from Europe, Japan and South Korea and other international companies.

Merger and acquisition value is the market and customer first

LiuJianYun argues that m&a itself consists of two parts, the first part is the enterprise value of mergers and acquisitions, the second part is the enterprise of trade value, namely: good acquisition value plus a reasonable structure of the deal. First is to market and customer and enterprise value of mergers and acquisitions, corporate market and customer for the acquired party has significance.

Both ladies round and Ann, and widely gallium with electricity, or is ronda and power, it is not hard to find, the cooperation between the enterprise integration, for whatever reason, occupy more market is every enterprise essential starting point.

Ladies circular polarization electric co., LTD., chairman of Jane to serve as in July, has said the future lighting market ladies round the next step of work center of gravity, the hope can find in mainland China depth cooperation system lighting manufacturers jointly develop the mainland market. And eventually choose cooperation with three Ann, ladies round three Ann photoelectric value is in mainland China has a vast market and the government's support for the led industry. As Jane serve as, three Ann photovoltaic capacity big, the cost is lower, the future of cooperation, can reduce cost, at the same time let the ladies circular polarization electric smoothly into the mainland market, three Ann photoelectric will be ladies to circular polarization electric international channels into overseas markets, to create a win-win situation.

Ronda electronic Su Feng is chairman, said the au in led encapsulation powerful SMT (surface adhesive) process, lights, lighting and other client can bring new customers for ronda, on both sides of the complementary is strong, can increase galleons in the au customer base.

Ronda electronics as the only company in Taiwan adopt "on the middle and lower reaches of a dragon pattern" production led manufacturers, has a wealth of industry experience. Su Feng is in June this year China's semiconductor lighting network reporter interview, said the effects of vertical integration appears is the key to have wide end market, is the sea. So do the vertical integration is the most important is to have the most downstream port.

How much is the enterprise based on the fundamental with market share of. Merger integration can produce scale effect, not only can integrate the resources of market, more easier to enter into its own with the aid of others strength are not familiar with the market, have twice the result with half the effort. Has operator is proposed, in addition to upward integration in order to enhance the quality and efficiency of production technology and reduce costs; With the traditional lighting manufacturers already some powerful pathways for the horizontal integration advantages, it is a important strategy.

Earlier this year, the traditional lighting giant leishi lighting refond optoelectronics with domestic leading led encapsulation enterprise combining the joint venture company, engaged in high power led lighting technology research and development and packaging products manufacturing and sales business. It is understood that the joint venture, the production of led devices will be mainly supplied to leishi lighting.

Refond optoelectronics choose cooperate with channels to win leishi lighting, is undoubtedly value leishi rich market channel resources, can for the refond optoelectronics products sales to open a broad sea.

In fact, with the merger integration, rapid development scale and development of port, in many international lighting giants have become adept. Through its acquisition of Germany osram 2011 siteco, encelium and traxontechnologies, achieve the led in the commercial, public lighting, architectural lighting, led lighting solutions, control in areas such as resource integration, speed up market occupation of led lighting applications. Philips lumileds completed through acquisitions a hierarchical layout, and merger and acquisition of the next few years for more than 10 enterprises focus on led niche.

In the fourth quarter of PCB material production development trend analysis in our country

Wed, 13 Mar 2013 02:55:44 +0000

Due to the rise in international copper prices and glass fiber cloth, fiberglass yarn boiler stop cold repair, make a shortfall in supply side of the case, the factory of copper foil substrates in accordance with the current situation, rising costs have the opportunity to raise prices, so the estimated PCB material production is expected to grow by 5% in China in the fourth quarter, up to nt $16.4 billion.

Review panels, said the third quarter, the third quarter is traditionally PCB industry busy season, should drive the PCB material needs, but stop at glass fiber kiln furnace annual repairs, coupled with the industry demand is weak, the production of PCB material industry in China is still a small decline 2.6%, output value amounted to nt $15.6 billion.

With domestic manufacturers for the fourth quarter in the view, the copper foil substrate manufacturers yao (6274) said, the past traditional fourth-quarter revenue will be soft, but also have some customers respond to before the national holiday as well as the copper price rises have the materials ready before, Taiwan yao for applications in the server board this year, business is better than the industry average, corporate forecasts, Taiwan yao recession will be controlled within 10% in this quarter.

Photoelectric also believes that, in the past month revenue peak fall in September, almost all q4 will follow seasonal factors and decline, but because the photoelectric products almost all have to break into the mainstream products, such as smart phone/tablet computer, demand is relatively, so the q4 quarterly decline is expected to better than average in the past.

Glass fiber yarn/rich Joe (1815) argue that cloth manufacturers, conservative views, about the fourth quarter of last October, has seen tremendous pressures from downstream vendors cargo strength, along with related electronic industry gradually downward revision in the fourth quarter, so to the fourth quarter remain conservative views; Dehong (5475) also think q4 demand weak, fiberglass cloth grain rate decline

Or will dominate the Asia semiconductor market in China in the future PCB

Wed, 13 Mar 2013 02:53:19 +0000

In the past few decades, Asia has always been a part of a global semiconductor market, from material and silicon supply until the assembly and the consumer market. Over the years, the region is thought to be the main foreign companies to reduce their production and labor costs as the main target. Although it is true, Asia is still the largest on earth, the lowest cost of production base, but the region in recent years has changed a lot in other ways. Since 2013, databeans inc company will start to provide a new quarterly market tracking report focused on the Asian market.

The semiconductor market in Asia more than $20 billion, accounted for about 70% of the industry. China is half a guide in Asia's largest market share accounted for 39%. Japan is the second largest market share of 20%, followed by Taiwan and South Korea respectively accounted for 15% of market share and market share of 12%.

In particular, has become a very different parts of Asia, full of nouveau riche to transnational group, different kinds of consumers and businesses. Japan has been for a long time, for example, is the world's largest consumer electronics original equipment manufacturers, including our familiar names, such as SONY, sharp, Toshiba. However, in recent years, Japan's ce original equipment manufacturer's dominance has been south Korean companies, including samsung electronics and lg electronics to siege. These companies benefiting from favorable trade policy and currency exchange services, rapidly improve the quality of brand awareness. Ce has become replaced Japan original equipment manufacturer (OEM) before, these giants have on the global market, has now been turned into a weak one, try to capture consumer again.

At the same time, China, was once known as designed for large amounts of low-priced commodity exporter, has become one of the world's most dynamic emerging consumer market. A group of emerging young wealthy consumers, make China become the main destination of foreign brands, such as apple and dell, are all here to submit the latest product line. In addition, due to the nature of the Chinese customers, China has become the many new electronic products "range". In addition, China is now many home-grown electronics original equipment manufacturer (OEM) and some of them (such as lenovo and huawei) are taking important steps to expand their foreign products in the consumer market, and competition with other global companies.

Companies in Taiwan, such as TSMC and umc OEM business has been the national business card for many years. Until recently, however, the Taiwan mode completely took over the "pure" wafer, contract has developed advanced technology, and become the global semiconductor industry most of the company's main production source. In fact, success fabs models created in Taiwan, this model has been used by global companies, including many of the integrated device manufacturers are already built.

Asia is home to India, a huge population of more than 120 million, the world's fifth largest economy, the gross domestic product (GDP), the second largest in emerging economies. Its scale and the potential user base in this area is one of the most penetrating consumer market on the planet, represented in JinZhongQi for original equipment manufacturers the most promising market. In fact, many Indian customers are buying their first phone, high-definition TV and PC, for some of the world's leading original equipment manufacturers is one important goal, they are looking for a new direction, to expand their market share. In addition, the Indian government has taken important steps in recent years to promote the development of domestic electronic industry and brand in India. Some original equipment manufacturers, such as mobile phone maker, lava international car manufacturers, tata motors (it's in the 2008 acquisition of British auto brands jaguar and land rover) even managed to expand to other regional markets

September phone competition heats up PCB

Wed, 13 Mar 2013 02:48:50 +0000

I to you, one day, New York has become the focus of global technology especially in the smartphone industry. First the morning of September 5, nokia launched two new Windows 8 system smart phones. Then MOTOROLA breath issued three in the afternoon the next generation of smartphones. Two mobile phone giant cluster appearance is so rare, purpose only one, a sniper to be released next week ahead of a new generation of apple iphone.

"Cluster" for the market

In one day "crash" launched its new mobile phone, both nokia and MOTOROLA, are helpless. After all, the next iphone will debut next week, don't launch its own new products, to attract users attention, market left by time and space will be left. In order to win the competition for time difference marketing, two giants: doing my best, come up with the latest cutting-edge products.

Nokia brings both lumia phones are equipped with the latest Windows 8 operating system, whether mobile phone technology and performance over the last generation. Among them, the mobile phone photography, Gao Qingbing display and wireless charging is three biggest selling point.

MOTOROLA after acquired by Google, the launch of the 3 mobile phone configuration also reached a new height. Specially to come to the platform of Google chairman Eric schmidt said that currently the activation of android devices every day number has reached 1.3 million units, the total installed base close to 500 million units, "from the point of platform, this allows us to occupy the position of the world". As the "son", MOTOROLA's future would be Google's full support.

Competition heats up in September

Before nokia and MOTOROLA, samsung, the world's biggest handset-maker has released two new phone, and HTC is set to be released back in a week in the I - phone "powers, the September 2012 was destined to become the worst January in smartphone industry competition. Each big manufacturers around the hardware, such as processor, display and large capacity battery, have been in heated competition, and in terms of the operating system, apple's ios, android, and Windows system situation of "three kingdoms" has already be vividly portrayed.

From the current market reaction, apple and samsung are still the first camp. Both market share and profit margins, apple and samsung all the greats in the absolute leading position, both almost occupies 90% of the smartphone market profits, revenue, more than 50%. Experts predict that smartphone shipments this year is expected to reach 519 million units, including use of apple's ios and Google android mobile phone operating system market share will as high as 76%. The android system because many manufacturers competition will be extremely tragic. HTC was performed last year, this year once fall into the predicament of the rapid drop in market share. The experts said, "the future of a star phone may change the fate of one company."

Apple wants to rob back to champion

On September 4, local time, the apple send invitation letter to each big media science and technology, announced on September 12, will be at a new conference. Response to this, global media is very warm, because before all sorts of information, apple will release new generation iphone. U.S. media projections, a new generation iphone will be equipped with a bigger screen, faster processor, a new generation operating system ios6 and support 4 g network function.

Apple iphone 4 s mobile phone, according to new market sales record since last year, in August of this year for the first time lost the mobile phone sales, instead of samsung galaxys3 issued in May this year, the machine now has global sales break through 20 million. But as apple released a new generation of the iphone, is widely expected to American media, apple will easily win back sales title.

Clouded electronics industry PCB

Wed, 13 Mar 2013 02:46:48 +0000

Between January and June 2012, the national electronic products import and export volume reached us $535.8 billion, up 1.9%; Among them, the exports of $319.1 billion, up 5.2% from a year earlier, 4.0% growth is lower than the national foreign trade export; Imported us $216.7 billion, fell 2.6% year on year, growth is lower than the national foreign trade imports by 9.3%.

From the point of sales value, in the first five months of this year, the national electronic information manufacturing industry above designated size sales output value 3.1724 trillion yuan, up 11.2% from a year earlier, but down 10.4% than the same period last year 21.6% growth, output increases the speed skating to their lowest since the 2008 global financial crisis.

Cold Numbers, is the real economy practitioners actually feel the management dilemma. For printed circuit board industry, shenzhen city, according to the circuit board industry association XinGuoSheng depression by the whole in the first half of the year, especially in the second quarter, companies within the industry fell by an average of three orders. Printed circuit board is in the electronic equipment support, connectivity of the circuit element components, known as the "mother of the electronic products. China dominated the global capacity of 4 into the industry, and in shenzhen for the capacity of 4 to China.

Investigate its reason, weak demand. Look outside, the world's major developed economies debt problem has not solved, the unemployment rate to maintain a high level, low consumption information; Look within, is China's GDP itself rare 8, industrial added value growth, retail, fixed assets investment, power generation, manufacturing purchasing managers' index (pmi) and other economic indicators are almost fully slowdown.

Growth is on the one hand, the decline in profitability is more let a person heart. Excess capacity due to shrinking demand, electronic product price decline faster, pressure is more and more big profits. Demand is still growing, but because the rising costs of factors, such as price wars and the human a lot of enterprises only choose order, or have no money to earn.

This aspect, also has the ministry's data support. Electronic information manufacturing industry in the first five months of this year, the industry profits fell 25.6% year-on-year, KuiSunMian reached 26.9%, loss of business losses grew by 81.5% year on year. Miit, according to the analysis of the corporate profits decline is mainly due to the reduced demand and the rising cost of two factors, the enterprise production and business operation cost, in the first five months of the industry's main business costs 2.8245 trillion yuan, up 10% from a year earlier, enterprises above designated size per one hundred yuan cost of main business income is 90 yuan.

The current difficulties, it's easy to let many business owners think of that crisis in 2008. The difference is that the situation is urgent, all of a sudden many enterprises didn't order, out, "now the situation has a warning signal from the second half of last year, is a process of slow down. But some worry that, just like a personal sick, slow the disease, go slow.

For the second half of the trend, the industry also exist differences. XinGuoSheng thinks, in June this year could be the wave of decline curve at its lowest level. He reason is that in recent period of time, China, Europe, the United States are "in step" to implement the quantitative easing monetary policy, and the conduction effect will transfer to the real economy in the fourth quarter. However, he also acknowledged that their association of enterprises also have to come up with various attitudes.

And real estate, such as the consumer demand different type industry, China's electronic manufacturing export-oriented characteristics is very obvious, the market can recover more depends on the degree of recovery in overseas demand. Invincible because apple products, however, the industry of rumors in the release of the iphone 5 in September this year. Eating the apple, the days will better - this is in recent years related industry chain practitioners concluded an iron law.

Semiconductor Renesas troubled PCB

Wed, 13 Mar 2013 02:38:34 +0000

Japan official institutions and private enterprises to consider invested 200 billion yen (about NT $ 745 billion), the acquisition of the deteriorating performance of semiconductor factory Renesas Electronics Corporation.
The report pointed out that Japan's official color industry innovation institutions will invest more than 150 billion yen to obtain 2/3 of the shares of Renesas. Toyota Motor Corporation, panasonic, about 10 companies plan to invest nearly 50 billion yen.
The Renesas supply enough around automobiles, home appliances performance microcontroller, Toyota, Nissan, Honda Motor Company, panasonic, Sony, Canon and other enterprises, are purchased from Renesas microcontroller customers, assist Renesas heavy whole, it is tantamount to enhance the competitiveness of their own company's products.
Integration Hitachi, Mitsubishi Electric, NEC (nec) semiconductor business established Renesas, including the predecessor companies date to the first quarter of this year, the seventh consecutive quarter of operating at a loss. The main cause is called the "head" of the system of flat-screen TVs and other digital appliances lsi (LSI), the cause of sluggish.

Common Problems and Countermeasures Pcb with fpc flexible circuit boards in the production process

Tue, 12 Mar 2013 09:26:08 +0000

Common Problems and Countermeasures Pcb with fpc flexible circuit boards in the production process

With the surface welding conversion to lead-free circuit boards are exposed to welding temperature up ultra-high thermal shock resistance of the surface of the solder mask layer become increasingly demanding, surface treatment of terminal and solder mask layer (ink, covering film ) The peel strength of the binding force of the base copper increasingly demanding, we need a way to have a better effect of the pretreatment process do protect. Product yield through improved our process to improve profit growth point. High-quality pre-treatment the syrup can undoubtedly low-cost help us a great favor.

This paper describes the PCB just line circuit boards and the FPB soft PCB production process will often encounter problems and countermeasures: a line section dry film or wet film processing, etching lines side etching, etching phenomenon insufficient or uneven lines, resulting linewidth. The improper reason nothing more than wet and dry film material selection, improper exposure parameters, poor exposure machine performance. Series might cause problems developing, etching segment nozzle adjustment, adjust the relevant parameters unreasonable, improper liquid concentration range, the transmission speed improper reasons. However, we often find that after checking the above parameters and equipment performance and no abnormalities, however the board will still be a circuit board over eclipse, etchback. What is the reason for it?

Second, do the PCB pattern plating, PCB, FPC terminal surface treatment such as Process Immersion Gold, Gold, and electrical tin, tin, we often will find the board to do it in the edge of the edge of the wet and dry film solder mask layer infiltration plated phenomenon, or most board or some places, no matter what kind of situation will bring unnecessary scrap or bad cause unnecessary trouble for the rear section processing, and ultimately scrapped distressing ! The reason analysis we usually think of wet and dry film parameters, material performance problems; covering film solder mask ink hard board, soft board with a problem, or there is a problem in the printing, lamination and curing section . Indeed, these places everywhere can cause this problem to occur. We also confused inspected more steps section and there is no problem or problem solve, but still there will be the phenomenon of diffusion coating. What are the reasons not to check out?

Circuit board before shipment at the tin test, customers course in the use of time meeting tin solder components. Two phases may occur, or occur at a certain stage of immersion tin or solder blistering, peeling substrate, is to do the tape test ink peel strength, tensile testing soft board that ink can cover film peel strength significantly peel or cover film peel strength is insufficient or uneven, this type of problem customers, especially customers is absolutely unacceptable to do precision SMT placement. Once the solder mask layer welding since photodetachment phenomenon will lead to not be able to accurately mount the original, leading to the loss of customers will face a large number of components and loss of working time, circuit board deductions, fed, and even lost customers and huge losses. So we usually encounter such problems in those aspects go about it? We usually go to analysis is not the solder mask (ink, cover film) material; screen printing, laminating, curing stage is not a problem; is not plating syrup? And so on. . . So we usually ordered engineers to be sure from the section - to find out the reasons, and to improve. We also think it is not the reason of the weather? More humid, plates absorb moisture? (Substrate and barrier hygroscopic) After an arduous struggle, how much can harvest these effects, temporary solution on the surface. However inadvertently such problems occur, then what is the reason? Section that may be a problem obviously has been checked to improve before you. What did not notice?

For more than belonging to a wide range of industries PCB, FPC confusion problem. An important reason why we carried out a lot of trials and studies, and finally found the produce bad line, diffusion coating, layered, blister, peel strength, the problem actually lies in the part of the pre-treatment. Before handling in wet and dry film solder mask processing, before plating processing part of the multi-section before. Here, perhaps many industries can not help but laugh. Pre-processing is the most simple, pickling, degreasing, micro-pitting. Which the same pre-treatment syrup, performance parameters and even recipes, many of the industry's technical staff are clear.

PCB levels electroplating technology

PCB levels electroplating technology

-------------------------------------------------- ------------------------------

I. Overview

With the rapid development of microelectronics technology, printed circuit board manufacturing multilayer laminated, the rapid development of functional and integrated direction. Procure printed circuit design a large number of tiny holes, a narrow pitch, the thin wire of the conception and design of the circuit pattern so that the printed circuit board manufacturing techniques more difficult, especially multilayer through hole aspect ratio of more than 5:1 and plot deep blind holes, so that a large number of laminates a conventional vertical plating process can not meet the technical requirements of high-quality, high-reliability interconnect holes. The main reason from electroplating principle of analysis about the current distribution of the state, found by actual plating hole current distribution presents waist drum-shaped hole in the current distribution is gradually reduced from the hole edge to the hole central, resulting in a large amount of copper deposited on the surface hole edge, we can not ensure that the hole central parts copper layer copper demand should reach the standard thickness, sometimes a very thin layer of copper or copper layer, in severe cases can cause irreparable damage, resulting in a large number of multilayer scrapped. Product quality problems to resolve production from current and additives to solve the problem of hole plating. In the high aspect ratio of the printed circuit board in the electroless copper plating process, mostly supporting role in the quality of the additive, with a moderate air agitation and the cathode move, carried out under conditions of relatively low current density. Make the hole in the electrode reaction control area to increase the role of plating additives can be displayed, plus cathode mobile is very conducive to the improvement of the covering power of the bath, increasing polarization plated pieces, coating crystallization process speed and grain growth speed of the formation of nuclei mutual compensation, to thereby obtain a the high toughness copper layer.

However, when the case of the aspect ratio of the through holes to continue to increase or appears deep blind hole, these two process measures seems weak, thus generating a horizontal electroplating techniques. It is the continuation of the development of vertical plating method and plating technology, which is developed in vertical electroplating process based on the novel. The key to this technology is to create a compatible, mutually supporting horizontal plating system, enables high dispersion capacity of the bath than vertical plating method shows more in the improvement of the power supply and other auxiliary device with the excellent functional role.

Second, the level of electroplating principle Profile

Horizontal plating vertical plating methods and principles are the same, must have the anode and cathode after power-generating electrode reaction so that the electrolyte main ingredients to produce ionization, the charged positive ions to move relative to the negative electrode reaction zone; charged anion to the electrode the positive phase of the reaction zone is moved to thereby produce a coating of the metal deposition and the released gas. Because the metal in the cathode deposition process is divided into three steps: that is the hydration of the metal ions to the cathode diffusion; metal hydration ions in the second step is through the electrical double layer, and gradually dehydrated, and adsorbed on the surface of the cathode; step is adsorption of metal ions on the cathode surface to accept electrons into the metal lattice.

Operating groove from the actual observed is the interface between the electrode and a liquid phase of the solid phase of the plating solution can not be observed in the heterogeneous electron transfer reactions. To illustrate the principle of its structure can be an electric double layer plating theory, when the electrode is a cathode and in the polarization state of the case, were surrounded by water molecules and a cation with a positive charge, due to the electrostatic force and the orderly arrangement of the cathode the vicinity closest to the cathode the cationic center point constituted set physiognomy and termed Helmholtz (Helmholtz) an outer layer, the outer layer away from the electrode distance of approximately of approximately 1-10 nm. However, due to the outer Helmholtz a cationic positive charges of the total charge, the insufficient amount of its positive charge to the negative charge on the medium and the cathode. The farther from the cathode bath by convection, the cation concentration of the solution layer is higher than the anion concentration. This layer due to the electrostatic force is smaller than the outer Helmholtz, but also by the thermal motion of the cation arrangement does not like the outer Helmholtz close and neat, this layer is known that the diffusion layer. Is inversely proportional to the flow rate of the thickness of the diffusion layer with the plating solution. That is, the faster the rate of flow of the bath, the thinner diffusion layer, anti thick general diffusion layer has a thickness of about 5-50 microns. Farther away from the cathode on the convective layer reach the bath called a main bath. Because the convection effect of the generation of the solution will affect the uniformity of the plating solution concentration. The copper ions in the diffusion layer rely bath by the diffusion and migration of ions delivered to the outer Helmholtz. Copper ions in the main bath rely on convection and ion migration will be transported to the cathode surface. Where in the horizontal plating process, the copper ions in the plating solution is transported to the cathode in the vicinity of the formation of electric double layer rely on three different ways.

Bath convection generation is the use of the external existing internal mechanical agitation, and the pump was stirred, the electrode itself oscillating or rotary manner, and the temperature difference caused by the flow of the plating solution. Nearer to the place of the solid surface of the electrode, due to the influence of the frictional resistance to the flow of the plating solution becomes more and more slowly, a solid electrode surface convection rate is zero. Convection bath from the electrode surface to the rate of formation of the gradient layer is called a mobile interface layer. The flow interface layer thickness of approximately ten times the thickness of the diffusion layer, the transport of ions within the diffusion layer is almost free from the influence of the convection.

Drinking places the role of the electricity, the ions in the plating solution by the static electricity caused by ion transport known that the migration of ions. Its migration rate is expressed by the formula as follows: u = zeoE/6πrη To. Where u is the ion migration rate, z is the number of ionic charge, EO is a charge amount of electron (i.e. 1.61019C), E is the potential, r is the radius of hydrated ions, the viscosity η of the plating solution. Calculated according to the equation As can be seen, the greater the potential E landing, the smaller the viscosity of the plating solution  sooner, the rate of ion migration.

The concentration of copper ions can be obtained according to the theory of electrodeposition, plating, the printed circuit board located on the cathode for non-ideal polarizable electrode, the adsorption on the surface of the cathode electron is reduced to a copper atom, the copper ions leaving near the cathode reduced. Therefore, the cathode will be formed in the vicinity of the copper ion concentration gradient. The copper ion concentration is lower than the concentration of the main bath this layer of the plating solution is a plating bath of the diffusion layer. While the copper ion concentration in the main bath is higher diffusion cathode region, continue to add to a low copper ion concentration in the vicinity of the cathode. The printed circuit board like a planar cathode, its current size and the relationship of the thickness of the diffusion layer of formula COTTRELL equation:

Where I is current, z is the charge number of the copper ion, F is Faraday's constant, A is the cathode surface area, D is the diffusion coefficient (D = KT/6πrη) of the copper ions and CB as a copper ion concentration of the main bath, Co is the cathode The surface concentration of copper ions, D is the thickness of the diffusion layer, the K wave Man constant (K = R / N), T is the temperature, r is the radius of hydrated ions of copper, η the viscosity of the plating solution. When the cathode surface of the copper ion concentration is zero, the current is called the diffusion limiting current ii:

The thickness of the diffusion limiting current size determines the concentration of copper ions, a copper ion diffusion coefficient and diffusion layer on the main bath. When a high concentration of copper ions in the main bath, the copper ion diffusion coefficient is large, the thickness of the diffusion layer is thin, the greater the diffusion limiting current.
Informed that in accordance with the above formula to achieve the higher limit of the current value, we must take the appropriate measures of process, that is, using the heating process. Because elevated temperatures allows the diffusion coefficient becomes larger, the faster flow rates can make it become the eddy-current and to obtain a thin and uniform diffusion layer. From the above theoretical analysis, the increase of the copper ion concentration in the main bath and improve the plating solution temperature, and a faster flow rate, etc. can improve the diffusion limiting current, and to achieve the purpose of accelerating the plating rate. The level of plating is based on a convection speed of the bath to accelerate the formation of a vortex, and can effectively make the thickness of the diffusion layer is reduced to about 10 microns. Therefore, when using horizontal electroplating system for electroplating, the current density can be up to 8A/dm2.

The key to the printed circuit board plating, is how to ensure the uniformity of the substrate on both sides and the conduction hole wall thickness of the copper layer of the. To obtain the uniformity of the coating thickness, it must ensure that both surfaces of the printed boards and the bath flow rate of the through-hole to be fast and also consistent, to obtain a thin and uniform diffusion layer. To achieve a thin uniform diffusion layer, the structure of the current level of plating system, although a number of nozzles, is installed within the system capable of rapid vertical ejected bath PCB, in order to accelerate the plating bath of the flow in the through hole speed, resulting in the rate of flow of the bath quickly, in the upper and lower surfaces of the substrate and the through-hole is formed into the eddy current, so that the diffusion layer is reduced and more uniform. Typically, however, when the bath sudden inflow of the narrow through-hole, at the entrance of the through hole plating solution also reverse reflux phenomenon, coupled with the primary current distribution, speech is often caused when the plating of the entrance hole area , since the tip effect causes the copper layer thickness through the thickness, and the inner wall of the through-hole copper plating layer constituting the shape of dog bones. According to the size of the bath the vortex flow state in the through-hole and refluxed, the conduction state of the quality of the plated through hole, only by a process test method to determine control parameters to achieve the uniformity of the plating thickness of the printed circuit board. Because the size of the eddy current and the return date or not by theoretical calculations informed, so only a measured process method. Learned from the measured results, to control the uniformity of the thickness of the copper layer of the through-hole plating, must be in accordance with the printed circuit board through-hole aspect ratio to adjust the controllable process parameters, and even select the electroless copper plating solution of high dispersion capability , and then add the appropriate additives to improve the power supply to get that reverse pulse current plating copper coating has a high distribution capacity.

In particular, the increase in the number of laminates micro blind hole, not only horizontal electroplating system for plating, but also the use of ultrasonic vibration to facilitate the replacement of the micro blind hole plating bath and circulation, improve the power supply to the use of anti-pulse current and actual test adjusted controllable parameter, the data will be able to obtain satisfactory results.

Three, the basic structure of the horizontal plating system

According to the characteristics of the horizontal plating, it is the printed circuit board placed by vertical becomes parallel to the bath liquid surface plating. When the printed circuit board for the cathode, and the current supply mode Some horizontal electroplating system uses conductive clips and two conductive rollers. Easy to talk about from the operating system, roller conductive supply is more common. The conductive rollers in a horizontal electroplating system in addition to as a cathode, and also having a transfer function of the printed circuit board. Each of the conductive rollers are mounted with a spring means, its purpose is to adapt to the needs of the different thickness of the plating of the printed circuit board (0.10-5.00mm). But appears plating parts in contact with the bath may be coated with a layer of copper, the surface for a long long time of the system will not be able to run. Therefore, the current level of the manufactured plating system, mostly the cathode designed to be switched into an anode, and then using a set of auxiliary cathode can be plated copper electrolysis dissolved away mutual rollers. In order to repair or replace the aspect of reasons, new electroplating designed taking into account the easy-to-loss of the site to facilitate removal or replacement. The anode is a the insoluble titanium basket array resizable, were placed in the vertical position of the printed circuit board, built with a diameter of 25mm spherical, the phosphorus content of 0.004-0.006% of soluble copper, the cathode and anode a distance between 40mm.

The flow of the bath is the use of a pump and nozzle system composed of the bath closed before and after the plating tank, up and down alternately a rapid flow, and can ensure the uniformity of the plating solution flows. Bath for vertically ejected printed circuit boards, buffer wall jet vortex is formed in the printed circuit board surface. Its ultimate purpose reaches printed on both sides of the circuit board and the through hole of the bath and rapid flow of formation of a vortex. Further tank equipped with a filtering system, wherein the filter used for the mesh is 1.2 microns, to filter the particulate impurities in the go during the plating process and ensure clean and pollution of the bath.

Should also be considered in the manufacture of the horizontal plating system easy to operate, and the automatic control of the process parameters. Because actual plating, with the size of the printed circuit board size, the distance between the different transmission rate of the size of the aperture size of the through hole and the required thickness of copper, printed circuit board, the size of the pump horsepower, the nozzle The setting of the direction and level of the current density and other parameters of the need for the actual test and the adjustment and control, in order to meet the technical requirements of the thickness of the copper layer. He will adopt computer control. Through-hole printed circuit board to improve the consistency and reliability of production efficiency and the quality of high-end products, before and after treatment (including plating hole) to complete the program in accordance with the process, the horizontal plating system is to meet the development of new products, listed needs.

Fourth, the development of horizontal plating advantages

Horizontal electroplating technology development is not accidental, but a high-density, high-precision, multi-functional, the needs of the special features of the high aspect ratio of the multi-layer printed circuit board products is the inevitable result. Its advantage is more advanced than the the vertical hanging plating process now more reliable product quality, large production scale. Compared with the the vertical plating process method has the following advantages:

(1) to adapt to a wide range of sizes, without the need for manual racking, fully automated operation, no damage to the surface of the substrate to enhance and ensure the operation process, is extremely favorable for large-scale production of the large-scale.

(2) in the process review, without leaving a clamping position, to increase the salable area of significant savings in raw material loss.

(3) the level of plating using full computer control, the substrate under the same conditions, to ensure the uniformity of the coating of the surface with the aperture of each printed circuit board.

(4) from a management point of view, the plating bath to add from the clean-up, the plating solution and replacement can be completely automated job management runaway problem will not be caused by human error.

(5) from the actual production can be measured as horizontal electroplating using a multi-stage horizontal cleaning, significant savings in the amount of the washing water and to reduce the pressure of the sewage treatment.

(6) The system uses a closed-end jobs, reduce contamination of the working space and the heat of evaporation of the direct impact of the process environment, greatly improve the working environment. Especially baking sheet due to the reduction of heat loss, saving energy unnecessary consumption and greatly improve production efficiency.

V. Summary

Horizontal electroplating technologies emerge completely order to adapt to the needs of the high aspect ratio through-hole plating. But due to the complexity and specificity of the electroplating process, in the design and development of horizontal plating system still exist a number of technical problems. It remains to be be improved in the course of practice. Nevertheless, the use of horizontal plating system for printed circuit industry is a lot of development and progress. Because this type of equipment in the manufacture of high-density multilayer use, showing great potential, it can not only save manpower and operating time and higher production speed and efficiency than the traditional vertical plating line. And reduce energy consumption, reduce the required processing liquid waste effluents, and greatly improve the process environment and conditions, and to improve the level of quality of the plating layer. Horizontal plating line suitable for large-scale production in 24-hour operations, horizontal plating line debugging when compared to the vertical plating line is a little difficult, it is very stable once commissioning is completed, the process to monitor the bath. adjust the bath to ensure stable operation for a long time.

Samsung pushed many low-end machine function low-end market to compete with nokia

Fri, 08 Mar 2013 07:54:18 +0000

Samsung pushed many low-end machine function low-end market to compete with nokia

Earn basin after full in the smartphone market, samsung and put into the function of low-end machine market. Yesterday, the reporter understands, samsung focus this month launched four mobile phone function that is designed for developing countries, can support up to five SIM CARDS. The move is considered a sword which nokia the former function machine "overlord".

Wait for a month, and in several sellers, ms zhao finally got her long-awaited sell a nokia mobile phone. Don't get me wrong, this is not a recent stores sell like hot cakes in the "big" or "quad-core" smartphones, but less than half now mainstream smartphone screen, very simple functions of smart phones. "Every man use a smart phone is a good man, because have to go home on time every night." On the Internet such a popular smartphones says the ms zhao to buy this phone, the main reasons for the more points the smartphone's biggest embarrassment, standby time is short.

In addition, staring at the screen for a long time to hurt eyes, rich gaming and entertainment applications involved and disperse the energy let the smartphones in the market demand has been criticized by many people at the same time. Simple and easy to use, long standby time, less radiation function of the machine and therefore a place not only in the low-end consumer market, but also attract some intention "to" the white collar. In this field, nokia is difficult to shake the reputation and status.

"Clearly, the samsung hope that through this a series of mobile phones nokia's leadership in the low-end market challenges." Analysts pointed out that although the % 27 s 2012 smartphones in the world is samsung, but if add function machine sales, is now the world's largest mobile phone manufacturer nokia still.

"Show off in front of the nokia wasn't so easy." A net friend on weibo. Like him, many in the industry and consumers think, nokia is extremely rich in the experience of cheap mobile phones design was born, in developing countries is still very high brand awareness. Samsung wants to use nokia this segment of the market, is not an easy task.

Smart watches: the next revolution of IT technology

Fri, 08 Mar 2013 07:43:18 +0000

Smart watches: the next revolution of IT technology

Desktops, laptops, smart phones, smart watches... Chip is writes more and more close, sooner or later, it will be implanted into human body, will we become half of the machine unit. Observers said xiang "communication, smart watches have chip, close to the body, but if you just treat it as a miniature computer, it is obviously a lack of imagination.

The next disruptive products

IT product of the next revolution on your wrist, not smart phones, but smart watches. On February 11, the New York times reported that, apple is focus on research and development of a mysterious smart watches: based on iOS iWatch. It has formed a 100 engineers team, including product designers, marketing personnel, hardware, and software engineers, etc.

A week later, according to the tech blog BusinessInsider reports, a south Korean BBS also out a couple of samsung smart watches on the mimic diagram, the table AltiusOS carrying samsung's own operating system, and equipped with 235 MB of memory.

May not use them for a year, the market will appear a similar product that looks like a watch, integrated most of the PC, mobile phone function, Siri voice, body control is given priority to, playing under the two ring it automatically boot, play two times it shut again.

If you have two pieces of bag to hold the "screen" - giant screen mobile phone, tablet, need a backpack to carry every day they walked up and down, text messages, phone, email will have to open the package and see as soon as the bell rang, the repetitive actions make people tired. The more fans of science and technology, more can feel convenient smart watches. It is a digital products (mobile phones, tablet) "bulletin board", email, text message, information will first feedback on the table. Through which users can do simple mail, SMS transceiver, with bluetooth headset answering the telephone.

Have the computing power button control to give priority to

At present, the prototype of the smart watch is more, up to date features in a mobile phone peripheral products exist. Like Canada vendor Alerta Pebble launched last year, this table to be involved in the CES consumer electronics show in January this year.

This table can receive SMS, email and other notifications, Pebble and smart phone via bluetooth connection. At present, the Swedish designer Anders Kjellberg, Japanese electronics manufacturer SONY, sharp also have similar products.

These products is given priority to with button control. Dial on the right side will typically have three keys: up, select, down, and is equipped with the left side of the back key. By key operation, the user can use their time, music, maps, video calls, bluetooth, wi-fi data transmission.

Their shape and watch almost: consists of a screen with a watch chain. Screen sizes may be within 1.5 inches, weighing less than 50 g, have certain storage capacity calculation, text messages, phone, etc communications functions, support for iOS, Android, etc. The third party applications, and mobile phone, tablet, PC data synchronous transmission, etc.

"But apple products disruptive is more than that." Li yi believes that apple has out why smart watch, is it is creating a disruptive product, now rushing into the enterprise in the field of smart watches, future will die very miserably.

Human health body sense of voice control monitoring

Six years ago to invent mobile phones apple innovation in recent years, there is reason to believe that it is draw to the most innovative energy, to try to redefine the watch. Real smart watches who will establish standard? Apple's cooperative research and development of patent technology, left a clue to the outside world.

According to the New York times, apple the formed 100 engineers team, focus on research and development more low cost sensors, voice recognition software. This means that the iWatch could use body feeling, Siri voice control, can sense the human heart rate, breathing rate, etc., with human body health management functions.

Earlier this year, otherwise, local media reported on the bendable glass technology, apple is interested in corning cooperation with the manufacturers. If the application on the iWatch, the screen may be using the flexible material.

In February, the Wall Street journal said that apple is negotiating with foxconn to develop smart watch technology, focus on reduce the power consumption of the chip, and let the chips is thinner. Thus, iWatch weight, size, degree of thin and light, life will be better.

Foreign technology BBS author Dan Nosowitz wrote, iWatch is a "quick inform screen", best function should be concise. "as long as able to display the time, there are two sliding up and down buttons to inspect the notice, avoid text manipulation."

Semiconductor industry market analysts forecast, Li Wenjuan similar Siri's voice will be the smart watch is the biggest selling point. "Smart watches is personal and portable, voice save touch process, can be to display the portability to the extreme."

The health management platform

As early as in 2010, apple introduced the iPod nano 6 (MP3) had cooperate with sports brand, Nike, the user can put sensors in Nike shoes, through the way of wireless sensors can be connected to the iPod nano 6. So that the latter can record the user movement time, distance, calorie consumption value and total number.

Some wearable products through combine with mobile APP, users wear in the body will be able to record the outdoor running track, and the energy dissipations of the estimate. After the creation of "smart watches, similar products will disappear." Li yi said.

"Just put smart watches as smaller mobile phones, PC, apparently without imagination." Xiang believes that smart watches now integrated mobile phone function, only is the first step on the original, "smart health management is the most revolutionary it."

Xiang believes that smart watches through own computing, storage, communications, sensor, data acquisition to human body health, and then to transmit data to the cloud platform, there are a large number of data platform behind, an expert in data analysis, conclusions, and then make decisions by professional medical personnel to the user.

"Smart watches and skin nicely together, will be built in temperature, humidity, infrared sensors, detection of blood sugar, blood pressure, various parameters, such as exhaustion of body will remind you to rest, there are signs of illness will warn you." Xiang said.

South Asia circuit revenue by twenty percent in February

Fri, 08 Mar 2013 07:34:36 +0000

South Asia circuit revenue by twenty percent in February

Influenced by 9 day Spring Festival holiday, Formosa treasures consolidated revenues are from January February recession; South Asia (1303) revenue 22.403 billion yuan, down 19.6%, the performance in the last of the treasures, Formosa plastics operations is not affected by the holiday, revenue 82.173 billion yuan, down only 7%. Legal person pointed out that with the petrochemical products prices, the downstream demand, treasures consolidated revenue of march is expected to improve.

Corporate forecasts, Formosa plastics in petrol and diesel prices are high, and the price difference between $20 a barrel of crude oil, season 1 is expected to profit with Formosa plastics for treasures king, after-tax net profit per share (EPS) of 0.8 to 1 yuan. Formosa plastics after-tax profit will be more than 1 yuan per share, Taiwan, South Asia, after-tax net profit per share 0.5 yuan.

Most revenue decline in South Asia, is the company in addition to petrochemical products, in addition to electronics, plastics, polyester and other processing department, the department accounted for forty percent of company revenue are take 9 days long vacation during the Chinese New Year, so even a false Spring Festival has the greatest impact. In march in South Asia, Formosa plastics group, points out that the mainland downstream polyester textile industry after the Spring Festival starts in succession, the operational performance will be expected to stabilize upward; Another shutdown propylene phenol (BPA) in the factory, only after labor bureau through the join operation. Expected in March, therefore, the overall performance will have obvious improvement.

Formosa plastics aspects, peoplethink, less working days in February, but because of the international oil prices continue to rise, better than expected in February. The Formosa plastics, 3 sets of refinery operation rate was 95%, light oil pyrolysis plant and more than 95%.

Formosa plastics products of little change, if the price is also haven't changed much, march revenue is expected to recover.

Machine parts, the lunar New Year holiday impact on the company's performance. But because of para-xylene (PX) prices in Asia, currently is soft, but prices are high above $1600 a metric ton, and benzene, styrene (SM) high profits, derivatives polystyrene (PS) and other plastic raw materials for profit improvement; Corporate valuation, Taiwan march earnings will not be too thin.

Formosa plastics companies said, now is the off-season, plus downstream home processing factory most of the rest, the Spring Festival in February sales than last month. But as a result of vinyl chloride (VCM), polyvinyl chloride (PVC) into the traditional peak season; Combined with Malaysia's state oil plant closings at the end of 2012, VCM and PVC market supply will be more tight. Accordingly, as a legal person that Formosa march performance is better than 2 months, or even in January.

ICT industry research: soft electronic trend is discussed

In global soft printed circuit board (FPCB) industry research report pointed out that for flexible printed circuit board manufacturers, 2012 was a bumper year, FPCB used in almost all popular electronic products, especially tablet computers and smart phones, it promoted the FPCB market. Global FPCB market size reaches USD 10680, compared with 2011 in 2012, increased by 15.2% over the same period last year. In 2012, the FPCB achieved strong growth in all electronic parts and components, and in 2013 will continue to maintain strong growth momentum. Global FPCB market scale is expected to reach USD 11628 in 2013, compared with 2012 will grow by 8.9%.

Global soft board market value of close to 90% is focused on Japan, the United States, Taiwan, South Korea, one of the first four soft board manufacturer is belong to Japanese manufacturers. Taiwan and south Han Ruan board manufacturers have mostly focused on touch panel, intelligent mobile phones, game consoles and other applications of personal consumer electronics products. And America and Japan and other countries are high-order precision electronic field, such as aerospace science and technology, national defense, military weapons, advanced equipment, hard disk drive components for medical use, precision rotary joint, the higher-order application field is Taiwan, South Korea or China soft panel makers also difficult to entry level, but also soft board market additional value and most profitable blocks.

The soft board industry well-known companies such as Expert Assembly Service, Eurocircuits USA, Moog Components, Auroacircuit... Etc, it is with remarkable performance in the area of more than soft board of professional manufacturers. Very special is the local soft circuit board manufacturers, in 2013 began work on soft plate printing ink supply focused on Taiwan, make inquiries from the beginning test to place an order to purchase all were launched, let Taiwan soft plate printing ink into soft board industry supply chain in the United States.

While in the past, the us soft board industry almost one-sided use Japanese soft board printing ink, rarely USES the local soft circuit board welding proof printing ink industry. 3nd purchase habits change, mainly by application of the trend of the market development, as well as Taiwan's soft plate printing ink technology and quality improvement. More important, but the Taiwan soft plate printing ink suppliers can handle of the diverse small amount of high rupture requirements production conditions.

Apple iPhone ignited a global consumer demand for smart 3 g phones, however, many consumers do not know in Apple, Nokia, Moto, Samsung, ASUS and hTC or mobile phones, has a soft panel makers breakthrough material contribution to the development in Taiwan.

Also is the new material to make mobile phones have become lighter, now the factory is working on how to make smart phones more economic cost. Because soft circuit board with the combination of the hard board, can replace traditional connector, not only enhance the stability of the circuit, but also reduce the design height and weight of the phone. Current soft circuit boards PI Cover used to protect a wiring Layer (film), have been replaced by quality and resistance to rupture soft printing ink, thus can greatly reduce the cost of mobile phone again.

In the past, however, soft circuit board material ownership control in the hands of Japanese manufacturers. Its self-sufficiency rate of soft proofing welding ink, for example, Taiwan is less than 10%. Based on the cost of materials, flexible circuit board manufacturers hope to get materials, supply chain support, while the Taiwan factory also hope to win material autonomy. After years of effort, the factory has started to show results, including soft ink suppliers such as crown products materials science and technology has won 80% in Taiwan adopt soft plate factory.

Champions league chairman Ye Sitao said product materials science and technology, the company's flexible printing ink is a thermosetting type soft soft gel ink, in addition to have the function of the resistance welding, also has the characteristics of the surface heat dissipation. When used to replace PI covering membrane, soft printing ink will be fully wrapped in soft lines, let the ribbon cable rupture soft printing ink of the extended protection won't fracture. Crown product soft heat dissipation characteristics of ink, will the current row away online heat energy by the ink from the surface, so can improve the signal stability.

2013 crown product materials science and technology self developed PIC (Photoimageable Coverlay) photographic development covering membrane, it can thoroughly solve the soft board companies face the problem of jack for a long time, to be held in shenzhen industrial zone with the mainland has soft board published technical meeting, cause soft plate industry interest high, and with crown product material for application of science and technology research and development.

The main battlefield of the Chinese into the integrated circuit

Thu, 07 Mar 2013 08:16:02 +0000

Continuing to adopt a central file, continue to put into operation a new plant, with the influx of foreign capital ... In recent years, China's IC market has been bustling.
Opportunities: the Chinese who in the world
In 2012, the hottest topic in the semiconductor industry is probably the collective decline of Japanese enterprises. "3.11" earthquake of 2011 as a turning point, Toshiba, Renesas, Sony and other Japanese enterprises occupy market share fell to 15% from 52% in the highest. In February 2012, the world's third-largest chip maker Elpida declare bankruptcy. The industry believes that an important reason for the decline of the Japanese companies is the lack of attention to the Chinese market. The world's top 10 semiconductor companies in 2011, for example, American Intel, Texas Instruments, Samsung, Hynix has production lines in China, with the exception of the Japanese companies.
CCID Consulting statistics show that mainland China IC market sales in 2011 was 806.5 billion yuan, accounting for 51% of the global IC market, while the U.S. market is only $ 55.2 billion, accounting for about 20% or so. "Twelfth Five-Year Plan" released in accordance with the Ministry of Industry and IC industry predicts that by 2015, the size of the domestic IC market will be more than 1 trillion yuan. This means that the next few years China's IC market will continue to maintain a rapid growth, ranking first in the world.
China has become the main battlefield of the integrated circuit, was the Chinese who may be the world.
Largest market means that the most intense competition, which has been the Korean series enterprises occupy the top spot of the world semiconductor market, the most eye-catching. April 10, 2012, South Korea's Samsung Electronics, an investment of $ 7 billion memory chip project officially settled in Xi'an, which is the largest foreign investment project in the electronic information industry since the reform and opening up. As early as in 2006, in order to seize market opportunities, combined with STMicroelectronics, Hynix Semiconductor to invest two billion U.S. dollars, the construction of the most advanced 12-inch production line in Wuxi. In recent years, the U.S. semiconductor giant Intel, Texas Instruments, have also set up factories in Dalian, Chengdu.
In the the foreign counterparts Zhuluzhongyuan "time, a number of leading domestic companies' performance is also very eye-catching. Ic design industry, for example, in 2011 the top 10 domestic ic design company finalists base of nearly $ 100 million, the Huawei Hisilicon sales revenue of more than 1 billion U.S. dollars, the Spreadtrum achieve sales of about 4.3 billion yuan, an increase of more than 70%. SMIC manufacturing field, since its establishment in 2000, the rapid development of mainland China has grown into the largest, world ranked fourth in the wafer foundry business.
Crisis: Chinese enterprises passive catch-up
Accompanied by a group of people shocking data of triumph of the Chinese IC industry. IC import amount of up to $ 170.2 billion in 2011, continued to rank as the largest amount of domestic and imported products and domestic products to meet the domestic market demand is still less than 20%.
Domestic and foreign companies, the generation gap is also very obvious. In 2010, the sum of the sales revenue of China's more than 500 integrated circuit design enterprises is only about half of the world's first design enterprise Qualcomm. Prominent among the SMIC, the world's largest integrated circuit manufacturer TSMC only 1/10 to 1/12 of its annual sales.
From raw materials, technology and talent to the market, the competition in the semiconductor industry is already highly international, the latecomer Chinese enterprises has been in a passive situation of catch-up. The integrated circuit of the importance of the national economy is self-evident, its application range covering military, civilian, almost all electronic devices. As China enters the information society, the information input, operation, output, storage must rely on integrated circuits, integrated circuits and national information security are closely linked.
Turning point: as a national strategy
Therefore, the establishment of self-control integrated circuit industry has risen to the national strategy. National long-term science and technology development plan (2006-2020) "integrated circuit equipment in major projects. Major projects breakthroughs in core technologies and resource integration in order to achieve national objectives, the completion of a major strategic products within a certain time limit, the key generic technologies and major projects.
Support from the country's development effort in 2000. In 2000, the State Council issued the text of the 18th, to support efforts to increase the chip industry is the most favorable that all industry support policies. The text of the introduction in the 18th directly spawned the first wave of development of the integrated circuit.
According to the China Semiconductor Industry Association data, the scale of China's semiconductor industry, from 56.16 billion yuan in 2002 soared to 281.431 billion yuan in 2011, and the average annual growth rate of 19.61%. The size of the integrated circuit industry jumped from 26.84 billion yuan in 2002 to 157.22 billion yuan in 2011, an average annual growth of 21.70% share of the domestic IC market share rose from 14.60% in 2002 to 19.49% in 2011.
In 2011, after the expiration of the text in the 18th, the State Council issued the new No. 18. The new paper on the support of a qualified IC enterprise technological progress and technological transformation projects, on behalf of the central budget. isuppli senior analyst Gu Wenjun pointed out that, given clear instructions on the funds for the "12th Five-Year" during the introduction of the national key projects and project, the integrated circuit industry to a higher strategic height.
Improve industrial competitiveness, self-control IC industry, which is behind the vision of the central file. However, in accordance with the stated objectives of the released by the Ministry of the integrated circuit industry, "the 12th Five-Year Development Plan, by 2015, China's IC industry can only meet less than 30% of the domestic market demand.
This is bound to be a long path to catch up.

Outdoor lighting is to benefit from the Government to create market demand, slow growth led lighting applications, only about 6% of 2012 led lighting penetration rate in the field of industrial lighting applications.
led lighting products has begun to the main lighting tool, but because consumers are more sensitive to price, resulting in a very low market penetration in 2012 led lighting.
Lighting market this year with the led lighting products continue to develop and expand at the same time the penetration as prices decline gradually increase, coupled with the new reference to the introduction and development of intelligent lighting, therefore this year led lighting still good prospects for development and the development of the LED lighting market is expected to significantly enhance

PCB Serious excess of domestic electrical instrumentation products

Thu, 07 Mar 2013 08:01:41 +0000

Pulling both urban and rural power grids, the domestic electrical instrumentation market is undergoing a series of changes. The domestic market demand analysis of the application of surface electrical instrumentation products extremely wide range of power sector is the largest user of electrical instrumentation products. From electricity supplies department report pointed out: Currently, the in energy metering instrumentation system, the user needs mainly 86 series of induction meter, electronic energy meter (single-phase) demand is expected there will be a big rise space.
Market demand for precision meter will tend to shrink, portable meters will reduce demand. This product is mainly concentrated in the instrument appearance, structure design, expanding applications, improve reliability, and other aspects. The digital instrument development focus is to improve the reliability.
Demand forecasts and price movements of the production capacity of domestic electrical instrumentation products have serious surplus of industry-wide profit status. But some high-tech products (such as electronic power meter, etc.) cost-effective compared with the old product will have a significant competitive advantage.
The data show that, in the next few years, the annual demand of the domestic market for electrical instrumentation products will be maintained at around 60 million units (sets). Among them, the power sector needs 54 million units (sets), other departments needs 600 million units (sets). Judging from the product structure, energy meter products demand of 48 million units, mounted electric meter product demand of 700 million units, a portable meter demand of 2.5 million units, a digital instrument demand of 1.5 million units, other instruments demand of 100 million units. The needs of all types of product structure changes in the proportion of the energy meter electronic energy meter products will gradually increase up to 12 million units from 200 million units in "15" initially to the end of expectations. Mounted electric meter, portable meter, digital meter technical content will also increase, escalating the level of the product. Therefore, although in recent years, total annual demand will not change much, but the total sales increasing trend expected annual growth rate of 8%

TV panel procurement of falling demand PCB

Thu, 07 Mar 2013 07:59:05 +0000

Chinese mainland manufacturers LCD TV panel procurement volume in December 2012 at their annual highest single month, to 7.55 million. Last month a slight growth of 1% (m / m), two percentage points higher than expected.
However, demand is expected to decline and higher channel inventory, the recent Chinese TV manufacturers panel purchases slowed down. Some panel makers even in the face of the order of 20-25% down. In addition, in the case of supply and demand situation reversed, panel makers in the recent time, will face some downward pressure on prices, shipments to the completion of the established goals.
LCD TV vendor procurement requirements is expected to be a substantial increase in late March, to meet the needs of holiday stocking.
Flat-panel TVs in all benefit from the product categories from the status of the implementation of the energy efficiency subsidies, subsidies for energy efficiency programs established at the end of May this year, the end of the first stage, the status of implementation of the best. As of last month, more than 6 billion yuan has been completed subsidies and five categories of products subsidy total is still less than 30 billion yuan. Therefore, the government has decided to maintain the overall energy efficiency of a subsidy of 26.5 billion yuan unchanged adjust subsidies proportion of subsidies for different types of products, thereby increasing the budget of subsidies for energy-efficient flat-panel TVs, which will undoubtedly grow demand for flat-panel TVs more favorable .
Is worth noting that, in accordance with the original provisions to benefit manufacturers of energy-efficient flat-panel TVs in the entire 12-month subsidy period, sales to reach the lower limit of at least 50 million units, which will have a smaller market share of foreign brands brand manufacturers to bring the risk of certain subsidies.

LED lighting export biggest obstacle PCB

Thu, 07 Mar 2013 06:39:56 +0000

Europe and the United States as a major global led application base, using the highly demanding technical and safety standards, technical barriers and the forward led export enterprises hit. Technical barriers to trade has become the biggest obstacle to China led lighting products, such as the export led light bar screen. In recent months, the European Union, the U.S. imports improve product standards led lighting industry Adds haze will be very difficult, this also means that a total of more than 8000 led enterprises export the road outside was in Europe and the United States, Japan, technical barriers "siege "within the Pro sluggish demand, the shortage of embarrassing dilemma.
"Lamp international standards iec62560-2011" states: "The lamps manufactured lamps normal use after installation and wiring, as well as the replacement of the light source or replace the starter and must be turned on lamps, even bare hands, the live parts can not be touched 's. " Inspection and quarantine personnel in the routine inspection process of export products, several find multiple manufacturers led lights one end inserted into the lamp holder, the lamp and the other free end for easy access to live parts.
Recently, Wuxi Entry-Exit Inspection and Quarantine Bureau in an area lighting products export inspection found that an export production for general lighting led lamp, self-ballasted structure is irrational, the cause is deemed to have failed and can not successfully export.
Guangdong Provincial Bureau of Quality Supervision the wto / tbt Center recently informed that setting a higher threshold, the European Union, the United States, Chile, Uganda and other countries and regions of the country directional lights and led lighting products. Covering energy conservation and environmental protection, eco-design, energy efficiency label, testing, inspection, performance, security, size, weight, shape, higher, more stringent requirements for entering the country directional lights and led lighting products. Such as the EU directional lamps and led lamps, energy-efficiency requirements.
According to statistics, in 2012, Ningbo totaled export lamps batch of 56,000, the value of $ 1.45 billion, an increase of 12% and 23%, respectively, compared with the previous year. From the product category, outdoor lights, solar lights, work lights, represented by the traditional lighting is still the flagship product of the export, accounting for 30% of total exports, an increase of 33% over the previous year; export lamps led lights as "reinforcements" in the proportion increases every year, accounting for 22% of total exports, a significant increase of 47% over the previous year. Country from the trade point of view, the EU is still the main positions of outdoor lighting exports, accounting for 51% of total exports, an increase of 13% over the previous year; importance of the U.S. market has become increasingly significant, accounting for 20% of total exports, compared with the previous significant year-on-year growth of 48%. From the scene to examine the situation, the export lamps substandard batches representing a decrease of 40% from the previous year; export lamp failure rate of decline of 0.41 percentage points over the previous year.
Although the start of led lighting market, but influenced by the prices, lack of domestic market demand, most of the products or export overseas. Therefore, the improvement of led lighting products export standards for some export-oriented enterprises will bring no small impact.
Enterprises to a positive view of the EU to improve the regulatory barriers to entry, the standard-setting international standards is an inevitable trend, follow-up is also possible to further improve. "Testing International Services Limited general manager of Shanghai Lai Nie Pengxiang it does not seem" long anticipated " . He pointed out that the The lighting quality indicators, a security problem, a product performance. Has been the traditional lighting companies to pay more attention to security issues, but when the lamps led era, the market will certainly be product performance and higher requirements.
Point of view from Yinzhou export situation, there are two distinct characteristics: First, energy saving and environmental protection products into the growth of a new bright spot. In recent years, under the impetus of the countries the trend of energy saving, led lights increasingly favored by the international market, lighting products continue to occupy the field of energy conservation and environmental protection has become the biggest highlight of Yinzhou lighting business; markets of developed countries into Yinzhou lamps exports The main positions. From exports to national distribution, Yinzhou lamps have been all over the world in 112 countries and regions, such as the European Union, the United States remains the main export market. Exports to the EU value of $ 69,007,000, accounting for about four percent of the total exports, exports to the United States amounted to $ 30,309,000, the value of exports of emerging market countries also showed good growth.

Significance of the analysis and development of 3D printing industry in China PCB

Thu, 07 Mar 2013 06:34:16 +0000

Recently, the British "Economist" magazine in the "third industrial revolution", the 3d printing technology as an important symbol of one of the third industrial revolution, sparked the attention of the world of 3d printing. As a new thing, 3d printing what is the meaning? Significance for the development of 3d printing lie?
3d printing (3dprinting) is an emerging technology for the manufacturing sector is rapidly developing, is called "the significance of the industrial revolution manufacturing technology. 3d printers rely on the state-of-the-art technology in multiple disciplines, some applications in the field of aerospace, automotive, motorcycle, household appliances, biomedical, and broad development prospects. The main process is the use of the technology for the production of: application computer software design a three-dimensional processing style, and then through a specific molding apparatus (commonly known as "3D printer"), liquefaction, powder, silk of the solid material layer by layer "Print "the product.
3d print the increased material manufacturing "(additivemanufacturing), the main achievement of the form. The growth material manufacturing philosophy is different from the traditional "remove" manufacturing. The traditional CNC generally manufactured on the basis of raw materials, the use of the cutting, grinding, etching, such as melting way, removing the excess portion to obtain parts and combined into a final product, and then to the assembly, welding, and other methods. Growth material manufacturing distinct contrast, without original embryo and mold, will be able to direct the computer graphics data, generated by increased material objects of any shape to simplify the manufacturing process of the product, and shorten the product development cycle, improve efficiency and lower costs.
Major materials and key parts of raw materials (powder, resin, wire, etc.), laser generator, control system, these three parts is the highest value-added domestic do 3d printing is doing assembly machines and molding software The large amount of powder material, which can subvert the traditional casting, machining; foreign manufacturers is 3dsystem the, stratasys eos, they are the whole industry chain gene Fun is the whole industry chain through.
Difference is that China and the United States, the Chinese market has great potential, the first in the world, but weak in strength of Innovation and Technology, materials, information technology, philosophy is not conducive to 3d print upstream technology development. 3d print development, industrial, consumer, both short-term point of view, the industrial market is more attractive. Many 3d printing process, the rate of finished products in accordance with the material and quality requirements, 3d printing and traditional manufacturing more efficiency, complexity, and difficulty of the above.
3d printing industrial machine price of $ 300,000, $ 1.5 million, while the domestic machine tool prices generally below $ 100,000, 3d printer is a machine, this industry is going to replace the traditional need to wait until the price of steel, labor costs, energy prices rose sharply information society formed can talk about competition; terms, better health care, education, aerospace, military, automotive and other applications trends.

PCB Strong incoming green lighting

Thu, 07 Mar 2013 06:32:19 +0000

On February 17, the semiconductor lighting energy-saving industry plan released by the National Development and Reform Commission, 2015, the total phase-out of incandescent 60w above; promotion of led lighting energy industry output value of the average annual growth of about 30%, to reach 450 billion yuan in 2015. Plan "clearly put forward to give priority to the promotion of indoor commercial lighting products and systems. The green lighting grand plans for the moment to." Recently, the general manager of Shenzhen Green Semiconductor Lighting Co., Ltd. (hereinafter referred to as the "green light") Chen Baodong said the Shenzhen Economic Daily Reporter .
, The reporter learned from his recount, green lighting for that day, in fact, has long been ill-prepared. Deep secret agents steadfastly in the two market segments led office panel light and clothing lighting in a long time, has come out of a steady development of the road, and seize the opportunities of the two market segments.
Precise positioning: three achievements plate light "boss"
"At present, the industry generally simple philosophy: What lighting products do as long as the market order. Outbreak in the market seems to want a clean sweep, led lighting industry. Precisely As such Tandaqiuquan, practice lacks a clear positioning Chen Baodong directed at the industry drawbacks, led this giant market, industry 'essential oils million' No, East West, a hammer, the majority of enterprises are faced with the situation of fragmented orders, the persistence and bulk orders are few and far between. The stick does not work and only clear positioning in segments dig three feet to something. "
In fact, the market segments is becoming the consensus of industry insight. John source lighting market positioning electricity supplier led Lighting sales first brand; the MOSO original layout led market, positioning in the high-power led power, get a group of large customers, led drive power shares ; the Yajiang lighting positioned in the field of stage lighting, the segments leading brands.
Is to see the value of the market segments in 2009, Chen Baodong enterprises to re-adjust from groping into the key targets, lock led office panel light market. The precise positioning of the green lighting products will soon be recognized by the market, in recent years, green lighting sales 100 percent year-on-year growth, from 25 million yuan in 2009, an increase of 100 million yuan in 2011, and won in foreign markets more stable customers. Chen Baodong said.
The green lighting is the largest led panel light manufacturing enterprises, is domestic led flat panel lamp standard setters. Led indoor lighting export competitiveness ranking in the first half of 2012, according to senior engineers led network statistics, green lighting the R & D and sales of flat-panel lights are residing in the first in the country. Shanghai World Expo Russian Pavilion, State Grid Corporation of Xidan office buildings, Shenzhen Jianshiyilai largest investment project - Huaxing Electric Project green lighting products.
The two-wheel drive: seize the clothing lighting market opportunities
led lighting commercial lighting, household lighting, outdoor lighting, lit lighting. Office, food, clothing, supermarket, hotel and other commercial lighting is generally divided into lighting. Each of these areas are not the same luminous efficiency, color temperature, color rendering index of led lighting products requirements.
Institute of Engineering led industry data show that in 2015, global led lighting output value will reach 150 billion yuan, which accounted for 50% of commercial lighting, 750 billion. Chen Baodong said 750 billion market, clothing lighting occupies 60% share, and occupies about 20% of office lighting. Those who have seized clothing lighting and office lighting two market opportunities, he also laid the rivers and lakes in the led lighting market position.
Currently, metal halide to break out the light discoloration due to the high temperature will make clothes, the human eye is not very comfortable, especially for high-end clothing store, you need to have a professional lighting to shape the experience of the environment. "Chen Baodong said that due to the current clothing lighting The trend is not obvious areas of market segmentation for green lighting focused on the development of this market, there is no doubt this is an opportunity. It is based on this analysis, their own shadows "boss" status is firmly in the field of flat panel lights, green lighting its eye and then gaze clothing lighting.
Company focus will be focused on creating clothing lighting brand, and open up the domestic market as well as overseas emerging markets, the development of channels. "Said Chen Baodong, green lighting its two brands have been formed: one for office lighting" green lighting " brand plate lamp based products; Hibernian "brand for clothing lighting was set up in September 2011.
With the existing 37 national patents, R & D gene, Hibernian developed lighting products for the apparel market environment. Its venture light color rendering index can reach 80ra, the spotlights can do the 80ra more, so that the light looks softer, increase the clothing of the body aesthetic. "Led lighting for the apparel field, our prices than metal halide doing less." Chen Baodong said that the two brands of "green lighting" and "Hibernian wheel drive, when the price is down, the market opportunities stabilization handshake.
The winning channels: lead led store era
Insiders say they want to move towards a store and a single product line must be crossed, the high price of the scarcity of professionals, the brand becomes vacant, the product positioning is not clear several major Hom. For this reason, despite the current National led lighting thousands of manufacturing companies, but in the terminal market, specializing in led product management businesses are few, led stores formed harder market climate.
Nevertheless, led lighting products, enhance sales, brand image, attract consumers, corporate culture promotion, product display and promotion, are inseparable from the store.
Tangled problems of the industry led to open stores infeasible when the pace of green lighting store has quietly stride. At present, the company has established offices in Beijing, Chengdu, Hangzhou, Urumqi 4 led clothing stores, and by authorized dealers.
Chen Baodong, green lighting will be a second round of financing in 2013, focused on the expansion of sales channels, including the construction of the store, dealer decoration stores as well as image display. Chen Baodong plan will be established in the country in 2013, 100 the led store (agents).
In the field of office lighting, green lighting also has developed a number of overseas distributors, promotion channels for emerging markets and the domestic market this year. Led panel light is focused on the overseas market, occupying 60% of the sales of the company, in which the export volume of the country for four consecutive years led panel light #. "Revealed that Chen Baodong, 2013, the company will also focus on developing Russia, India and other countries led lighting market.
In the next few years, with the commercial development of the economy, as well as office lighting market start green lighting will also usher in a new round of growth in the peak period. Investors in accordance with the planning, green lighting every year to reach 100% growth. Recent years, the company completed the goal this year, with the successful laying of the channels, led lighting sales is expected to achieve 2 billion Yu-Chen Baodong said.

IPhone demand in 2013 will begin to decline to 10 reasons

Thu, 07 Mar 2013 02:39:35 +0000

IPhone demand in 2013 will begin to decline to 10 reasons

Recently, eWeek website, according to the analysis of articles published in the apple iPhone has retired. Although the iphone is still widely popular and sales are growing each year, but the iphone can always keep a mobile industry dominance has been questioned by more and more.

Like the samsung Galaxy S III of mobile phone has made people put forward the question. Apple's mistakes and missed opportunities also make people put forward the question. In this process, some people can't help but wonder if the iPhone in 2013 will be hit by the falling demand.

Falling demand, of course, is a relative term. In the case of the iPhone, this does not mean that iPhone sales will drop dramatically. On the contrary, the situation may be iPhone sales growth to slow this year. For apple, the worst may be iPhone shipments fell in 2013. In either case, the consumer and enterprise user demand for the iPhone in 2013 will fall to some extent.

Don't believe me? Here is the iPhone demand in 2013 will begin to decline to 10 reasons.

1. Apple will fail in the hardware performance competition

The mobile users need powerful hardware performance. Users need to their mobile phone to play games, provides the best performance, and within a year will not go out of style. Around the mobile space, however, apple is hardware performance in the competition. Samsung and other companies to provide product configuration faster processors and better graphics card. Consumers begin to realize this.

2. Apple also will fail in the function of competition

Apple will not only fail in hardware performance in the competition. From the contrast of technical specifications, apple's iPhone started behind rival devices. For example, the iPhone 4 inch display 1 inch smaller than main rival mobile phone. What's worse, the iPhone's lack of support for NFC technology, its quality also lags behind that of nokia mobile phone camera the camera. At least in the field of smart phones, the iPhone is no longer such deep impression of the product.

3. The iOS has fallen behind Android

When apple iOS, far ahead of the mobile operating system at the time of any operating system on the market. However, iOS behind Android now. Android to fully support NFC, for example, data transmission and multiple user accounts. Use samsung's Premium Suite Upgrade (advanced) Suite Upgrade, users will find many other good features, for example, to the position of the rotating screen according to user's face. At the same time, the iOS software technology is a good 2010. In the mobile market, two years is a long time.

4. Embarrassed

It is important to point out, apple and its operating system in the past two years, there are many embarrassing things. When apple launched Siri assistant function, this function is to enhance people's working efficiency. Siri but became a laughing stock, however, because the voice response technology not much improvement. Apple last year's poor performance maps application. User is not forget these defects. Due to worry about these problems, the user may consider when buy the iPhone this year.

5. China will be a worrying problem

Apple has a serious marketing problem in China. Although apple's iPhone is very popular in some circles, however, have not reached the popularity of apple hopes. The great problem is that the iPhone is not sold on the China mobile. Is China mobile operators have more than 700 million users. Another problem is that the iPhone's sales in China than in the United States sales price you hundreds of dollars. In fact, the iPhone is too expensive, apple has started for the iPhone offers a monthly payment plan. In a there are still many people living below the poverty line, your price is a problem.

6. Propaganda is waning

When Steve Jobs (Steve Jobs) management of apple, apple's propaganda machine has been running very well. However, apple's propaganda machine is now weakened. CEO Tim Cook (Tim Cook) not as charismatic as Steve jobs. Apple lost a lot of star charm. Consumers are beginning to realise that apple is no longer the only able to offer exciting products company. Apple's latest mobile product update has some boring also illustrates the problem.

7. Upgrade the iPhone this year maybe a small amplitude

Observation of the history of apple, the apple iPhone every other year on a significant upgrade. If apple again this year, according to the plan implementation, the iPhone 5 s will only is upgraded to the iPhone 5 is very small. For a company to improve its product demand, it is a problem.

8. Samsung's challenge

Many discussions about the iPhone's involve apple in the mobile space: one of the biggest rivals samsung. Samsung is not only the main enemy of apple in a patent court, but also provided with apple iPhone as good or better products company. Samsung's Galaxy S4 smartphones are expected to be launched in the coming months. The phone could be far more than the iPhone 5. If this is the case, apple will be difficult to keep up with the pace of the samsung.

9. Google is a huge threat

We also don't forget that Google is a huge threat to apple. Over the years, Google has been improved. Now, Android may better than iOS. In addition, Google will partner with the manufacturer with a large number of hardware investment. Focus on this year, Google will take action against the iPhone's mass.

10. The problem of "value"

All these issues boil down to one final question: apple can really win the "value"? Since 2007, with reasonable price for the iPhone are widely believed to seek high-end performance of ordinary consumers is the most valuable. Now, however, this opinion is not necessarily true. The price of the iPhone in the high-end smartphone prices range. Considering the function of the iPhone still short of some competitive product level, now also don't see how much consumers will be found in the iPhone this year. Whether you believe it or not, the iPhone in 2013, may lose the reason of high price.

The yen adverse PCB factory international orders

Thu, 07 Mar 2013 02:36:27 +0000

The yen adverse PCB factory international orders

Under the yen depreciated effect, has nine mingle factory cut price, reflect on the industry, the devaluation of yen effect is unfavorable to Taiwan PCB industry of international orders. Workers being Jiang Baifeng IEK industry analyst, Japanese domestic PCB industry production decline 5.8% last year, Japanese companies sitting on Japan's currency advantage, if the Japanese companies take the price strategy, international orders will threaten the PCB industry.

Work being published IEK got nowhere PCB industry production situation and the outlook for 2013 predicts that strong yen depreciation effect has become one of focus since last year, according to statistics, between August and January last year, the yen depreciation rate is as high as 16.4%, this year the yen still see fall, decadent for a long time to save Japan's economy; In contrast, t and the renminbi, in the past 1 year have rise by 2.9%, 2.9%, is not conducive to Taiwan's electronics industry.

Jiang Baifeng said that Japan's domestic production of PCB production last year 5.8% of the decline, the yen continued devaluation will help Japan's enterprises on the international price competitiveness, but slow Japan in production has been at the pressure of high cost; Is a weakness for Taiwanese businessmen, on the one hand, upstream materials procurement and production equipment, Taiwan to Japan may require that Japanese price cuts, the disadvantage is that if Japan's PCB industry product price reduction measures, may threaten Taiwan PCB industry on international orders.

And for Taiwan business people on both sides of PCB production, in the second half of last year because of poor information industry booming, result in output value only modest growth in the second half of 2012, according to statistics, in the first half of last year production value of 251.5 billion yuan, in the second half of 270.3 billion yuan only, and in the second half of the proportion of 48.2% to 51.8%, in the past into the second half of the traditional peak season effect tends to blur.

The semiconductor market will be facing the inventory adjustment in Taiwan

Thu, 07 Mar 2013 02:28:39 +0000

The semiconductor market will be facing the inventory adjustment in Taiwan

Taiwan Semiconductor rising inventory levels, packaging and testing plant products with silicon ASE agreed that the semiconductor market in the near future will face a fear inventory adjustment.

Chairman Lin Wenbo silicone products, recently said that because of Japan's earthquake, some manufacturers made duplicate orders in the second quarter of , probably will start the inventory adjustment in third quarter, showing long and short caused the current industry climate chaos.

ASE Tien Wu, chief operating officer recently pointed out that, according to statistics, the semiconductor market in the fourth quarter inventory levels of about 66 days, the first quarter of this year, inventory levels rising to 73 days, higher than the fourth quarter of last year, 7 days, 70 more than the normal water level day about 3 days.

Tien Wu said that the Japanese earthquake, the first quarter of the supply chain is repeat orders, but is only in May until the first quarter of the semiconductor inventory statistics released, the public is shocked to find that inventory levels are too high, the market order immediately at the emergency brakes in June .

Tien Wu said that in the first quarter rising inventory levels means that end-market demand as expected, although in June the market orders emergency brakes, it is estimated in the second quarter will continue to maintain high inventory level.

Market inventory adjustments will continue long, Tien Wu declined to comment, but he pointed out that it will be continued to adjust July and August.

In 2013 China's electronics industry market will usher in new opportunities

Thu, 07 Mar 2013 02:25:04 +0000

In 2013 China's electronics industry market will usher in new opportunities

Global electronics industry in 2013 will still be affected by the global economic situation, in the condition of low. The United States and the European Union is still trapped in the state of low economic growth and high unemployment, the economy is difficult to clear improvement. China's economy after a decade by the high-speed development, investment growth also slowed. But as the end of 2012 the world's major economies have just finished the government transition, the new leadership will publish some policy, to global economic growth, including the electronics industry, it might have some positive role.

In addition to the traditional electronic consumer products, I think China has created a new opportunity: areas of beidou navigation positioning and related products and industries. China in November this year launched 16 beidou satellites, formed a complete coverage of the Asia Pacific region beidou navigation network. The government will support the beidou satellite navigation industry policies, stimulate the development of various applications. These measures will lead to beidou navigation related industry development, such as navigation, control, timing, communication and navigation functions with the combination of industry, and so on.

As the Chinese government will ICD code announced to the world, China's domestic chip manufacturers will face the serious challenge of foreign large companies or enterprises. These foreign big companies, not only accumulated rich technology mature, and have abundant capital, investment can make the chip performance more optimized production process, these are all domestic manufacturers in the current situation is difficult to compete.

In the face of these challenges, including declining ASP the average selling price (product) and profitability, electronics industry must integrate and adjust. Specific measures include to make electronic industry really selections in the market. For management and technical ability weak company, let them out in market competition, reduce government intervention or subsidies. So, market supply and demand will be gradually towards a balanced and reasonable, the price also will return to the rational.

Second, must want to innovate in product design. Only constant innovation, is likely to produce high added value, for the market to accept the products. Third, we should constantly expand the international market, especially in the relative political stability of developing countries to establish the market demand and the corresponding technical support and sales infrastructure. Only the cake bigger, that is, big market capacity, to increase business. Finally, you also need to further reduce the production cost of products, make it more competitive.

In 2013 China's electronics industry market areas of concern are: electronic industry related to the compass/GPS navigation, such as navigation, monitoring, navigation, and the combination product of communication function; Intelligent location-based services (LBS) and related industry; Intelligent family related to electronic consumer products; Smart phones and smart mobile devices; LED commercial lighting industry to replace the traditional incandescent lamp lighting. Especially under the policy of the government leading, can produce a big LED lighting market; Represented by LTE 4 g communications industry; With cloud computing as the center of the electronics industry; The tablet industry.

These industries can rapidly growth, the main driving force comes from the market itself, bring the corresponding value for the society. In addition, due to the need of environmental protection, energy conservation and emission reduction, the government can publish relevant policy, to support and accelerate the application of new technology products on the market. LED commercial lighting, for instance, to replace the traditional incandescent lamp lighting, the government can through the form of legislation, to advance the promotion of this technology.

To sum up: the New Year, China's electronics industry faces the challenge of: low-end products of vicious competition, profit margins decline further, repeated investment and so on. Is likely to see sales on the rise, but still no growth or decline in turnover, or the status of the profits are falling. But domestic electronics market still has great development space, especially the focus of the government in the future, will be placed on expanding domestic demand and improving people's livelihood. The trend for China's electronic products provide a broad opportunity.

Thu, 07 Mar 2013 02:20:30 +0000

Phase 2 PCB's expansion plans have emerged

PCB factory new factory phase 2 expansion plans have emerged, jian ding (3044) will be depending on the season 2 order status, will hubei xiantao 1 times the factory production capacity; As a fine family (6191) also estimated in the third quarter, elevate hundred sichuan chongqing factory 1 times the capacity up to 1.2 million feet; Race than in Thailand, Thai ding (4927) new factory expansion has also synchronize best, has several big infusion of new factory this year revenue.

PCB factory new plant more than 2013 online ones, in addition to the new factory is located in the mainland, being located in Thailand billion electronics, F - Mr. Ding also have a new factory for expansion.

Jian ding, for example, hubei xiantao factory have a formal production, the capacity has reached 400000 feet, in February because of the order status is not bad, jian ding season 2 will be according to the condition of order, to increase capacity at 400000 feet, make its can output at 800000 feet, jian ding estimated that after the lunar New Year this year began to recognize revenue xiantao factory.

As a fine family sichuan and chongqing factory mass production for the fourth season last year, 1 the quantity to 300000 feet, 4 capacity is expected to reach 600000 feet, came to the stage of full capacity, as a fine family is for phase 2 original expansion plans, the fastest production capacity will increase in the third quarter of 600000 feet, expansion rate is 1 times, on the total capacity of up to 1.2 million feet, to supply to the nearest local NB contract required.

For Thailand, competing countries turn investment race billion electronics now of the moving rate is about 60% ~ 60%, the third quarter have access to full stage, race also intentionally will increase production capacity from 500000 feet to 500000 feet, the hardware architecture is enough to cover the 800000 - foot requirements, only need to import new equipment can increase production capacity.

Competing countries, points out that at the current order situation, competitive electronics into the full probability is very high, in the race of the year electronic flat to loss as the goal. Race in 2013 are estimated to 2 become a target of group revenues in order to grow, competitive electronics is expected to grow twice as up to 1.4 billion yuan, is a leading group sales growth.

, also in Thailand Thai ding 2 factory progress is slower, the plant is expected to import production in August this year, after August gradually recognize revenue, thanks to massive production capacity to join operations, this year's ding has more flexibility in production scheduling, the company will transfer the total capacity of up to 10% weight hard board, the drive plate revenue share, from 3% ~ 4%, rising to 10%, the highest growth rate, the largest product lines.

Due to the PCB factory to new factory this year increase rate of slightly ahead of last year, so the market expected, PCB equipment factory orders status should not bad this year, extremely has the opportunity to return to growth track.

Hewlett-packard (HP) spread to sell PC business PCB industry concern now

Thu, 07 Mar 2013 02:17:20 +0000

Hewlett-packard (HP) spread to sell PC business PCB industry concern now

International companies HP last year came to exit the PC market, industry research institute believes that if the rumor is true, could impact of printed circuit board (PCB) industry in Taiwan. HP last year December 27 to the securities and exchange commission (SEC) to submit documents, points out that continues to evaluate sell "no longer will be beneficial to the realization of the target assets and business departments".

HP said in the filing, "is likely to sell 1 item business, its price and terms as HP originally thought", and "selling business for HP revenue growth impact may be larger than expected". Market participants speculate HP could sell PC (personal computer) business group.

Industrial technology research center (IEK) ITIS sankei shimbun plan Zhao Zuyou industry analysts pointed out that HP for the global PC market leader, hewlett-packard (HP) in the PC market share of 16.5% last year, slightly higher than the second 14.9% of lenovo computer.

Commercial is an international brand PC market for PCB products, one of the biggest suppliers in international brand manufacturers to exit the PC market rumors spread, Zhao Zuyou, said concerns may impact the Taiwanese international orders fell, will affect Taiwan PCB production decline.

Zhao Zuyou further pointed out that the PC product is down by smart phones and tablet computers, the future growth slowing, and market prices always reaching down, in the face of market demand shortage in the future.

Zhao Zuyou suggested that the domestic PCB industry should transfer application products as soon as possible action, began to cut into other new fields of application, improve the production plants of grain rate, to reduce the impact may be short of PC order.

Zhao Zuyou, moreover, pointed out that Taiwan PCB industry has is a very important supplier to Apple (Apple), last year's fourth quarter in the iPhone 5, iPad 4 and iPadMini products with Apple pulled goods, leading to supply Apple PCB manufacturer for revenue, lift Taiwan PCB production growth of 5.5%, the scale of nt $108.3 billion.

But in the first quarter of this year on the off-season, orders, under the influence of Taiwan PCB industry output value will decline by 7%, and the scale will fall to 100.7 billion yuan.

How To judge the quality of the merits of the board from the color of the PCB circuit board

Wed, 06 Mar 2013 08:45:20 +0000

To judge the quality of the merits of the board from the color of the PCB circuit board

General PCB buyers who always have questions about the color of the PCB, they do not know what color the line we board, Lane is good, and today we have to explain the the PCB color on the performance of the circuit board what the impact will.

First, PCB is mainly to provide the interconnection between the electronic components. The Color In fact its performance has no direct relationship. Different color nor will it affect the electrical properties of the performance level of the circuit board is determined by the materials used, layout, and other factors as the number of layers of the board. However, in the process of doing the circuit board, the black is most likely caused by the chromatic aberration, if the use of raw materials and production process lines MILL slight deviation, there will be elevated due to chromatic aberration caused by the defective rate of the PCB board. This causes increase in production costs.

Second, the circuit board raw material in our life is very common, it is by such as glass fiber and resin. Two kinds of combination, hardened to form a heat insulation, insulation, not easily bent plate. This is the circuit board substrate. In general, such as glass fiber and resin into the PCB substrate alone can not pass the signal, so we will be covering the surface with a layer of copper, so we called PCB substrate for the copper-clad board

Black PCB circuit traces illegible will increase the difficulty of the R & D and after-sales maintenance and debugging stage, generally, if not profound skill RD (research and development) designers and powerful brand of the maintenance team, is not easily use black PCB 's. It can be said that a black PCB is a brand confidence in the performance of the RD design and post-maintenance team from the side, but also manufacturers confident of their own strength a reflection.
For the above reasons, the major manufacturers in the the PCB version designed for the product selection will be carefully considered. Formed when most of the market, large shipments of products using red PCB, green the PCB or blue PCB version black PCB, can be seen only in high-end or top flagship product, so customers do not think that black PCB than the green PCB.

FPC circuit design should pay attention to the problem

Wed, 06 Mar 2013 08:22:09 +0000

FPC circuit design should pay attention to the problem.

The following problems Shenzhenshilong Sea Circuit Technology Co., Ltd. engineers PCB circuit board design Some suggestions:

First, the design of the circuit board pad, be careful not to overlap.
1, Usually the pads are provided with holes, generally pads overlap addition SMT pad, it will cause the overlapping of the holes and the hole once overlapped, the drilling machine will normally be several times over the course of a drilling This guide to the broken drill bits, which will damage the hole.

2, the above is a single sided, if made of plywood, two holes overlap, such as a hole in the Land (flower pad), another hole for the isolation plate, two holes out of the film after isolation disk will cause scrapped.

Above, we design a circuit board files must be careful not to overlap the hole is pad.

Second, pay attention to design do not abuse the line layer

1, the general design software has said level, was the only line of double-sided, indeed in the inner layer more useless lines, or a four-layer board, come up with five lines (some lines is useless). So easily misunderstood. Please note that in this respect.

2, and sometimes our designers also breaching conventional design BOTTOM surface component side, the welding surface design to TOP.

Third, do not misplacing characters

1, if the characters cover the pad SMD give off printed circuit board testing and welding inconvenience.
2, there is little character design is too small, printed more difficult, too big and make the characters overlap illegible.

The IV filled the block copper or painting line acts as a pad, we need to manually draw the corresponding solder mask data.
Filled the block copper or painting line to act as a pad by the DRC check, but in the corresponding layer is not automatic production solder mask data, so that the pad will not open the window, welding regional conference solder mask oil layer to the device welding difficult, it is recommended that we want to avoid this situation, it is this case, we need to draw the corresponding solder mask data manually.

Processing level definition is not clear

, Especially single panel, some people will line design in the TOP layer, it was designed in the the BOT layer (conventional, general BOTTOM layer), in which case we generally need to be explained. Or easy to do wrong.
2, there generally we do a multi-layer circuit board, there is a layer of the order of, for example, a four-layer board design using the TOP in1 in2 bottom four, but we are processing, if you do not order this, you need a system board Description indicate.

Seven, do not design a circuit board files do not use a very fine line to fill many blocks.
1, such as a file in the large-scale use thinned filler block, easy production of the light will be data loss.
2, due to the file thin line, thereby increasing the amount of data, so that the file data, and to increase the speed of data processing.

Eight, and try not to pad surface mount devices designed too short

This is mainly energy off test, too dense surface mount devices, their spacing is very small, the pad is also fine to arrange testing needle, up and down the staggered position (left and right), if the pad is too short, rendezvous test needle wrong not open a bit difficult, resulting in test.

IX a large area of the grid spacing design is too small

Composed of a large area of the grid lines with the line between the edge is too small (less than 0.25mm) Figure transfer process is prone to significant shadow after a lot of broken membrane attached to the board in the PCB manufacturing process, resulting in disconnection .

10, designed not to a large area of the circuit board copper foil from the frame too close.

Copper foil from the outline of a large area should at least ensure that the spacing of 0.2mm or more likely to cause copper foil milling shape, such as milling the copper foil Qiqiao and arising out of the solder resist shedding problems exposed copper.

XI frame to design clear

Many customers will be guilty of this case, some customers keep layer, said some top over layer, some mechanical layer, but some of these layers are drawn, but do not overlap, so that we The circuit board manufacturer is difficult to judge which lines prevail.

XII large copper on the general board, we try to use the grid lines, so good to avoid SMT soldering copper blister.

Basic knowledge of the aluminum plate

Wed, 06 Mar 2013 08:13:13 +0000

Basic knowledge of the aluminum plate

Because of the high thermal conductivity of aluminum, the cooling performance is good, can effectively export the internal heat, the product of choice for LED manufacturers. The aluminum plate is a unique metal-based CCL, with good thermal conductivity, electrical insulation properties and machining performance, we should try to design the PCB near the aluminum base, reduce the thermal resistance of the part of the potting.

The following, I will introduce some of the characteristics of the aluminum plate:

First, the aluminum plate purposes:

Usage: power hybrid IC (HIC).
Audio device: input, output amplifier, balanced amplifier, audio amplifier, preamplifier, power amplifier.
2 Power supply equipment: a switching regulator `DC / AC converter` SW regulator like.
3. Communication electronic equipment: high-frequency amplifier `filtering appliances` transmitter circuit.
Of office automation equipment: motor drive.
Car: electronic regulator `igniter` power controller.
6 computer: CPU board `floppy drive` power supply unit.
The power module: converter `solid relay` rectifier bridges.

Second, the aluminum plate features

1. Using surface mount technology (SMT);
2 in the circuit design, a very effective treatment of thermal diffusion;
3. Reduce product operating temperature, increase power density and reliability, and extend the life of the product;
4. Smaller footprint, lower hardware and assembly costs;
5. Replace the the fragile ceramic substrate, to obtain better mechanical durability.

Third, the structure of the aluminum plate

Aluminum CCL is a metal circuit board material, composed by a copper foil, the thermal insulating layer and the metal substrate, and its structure is divided into three layers:
Cireuitl.Layer line layer: the CCL line equivalent to the ordinary PCB copper foil thickness loz to 10oz.
DiELcctricLayer insulating layer: insulating layer is a thermal insulating material of the layer of low thermal resistance.
BaseLayer grassroots: a metal substrate, typically aluminum or selected copper. Aluminum Copper Clad Laminate and traditional epoxy glass cloth laminated board.

Circuit layers (i.e. the copper foil) are usually formed after etching the printed circuit, so that the various components of the element are connected to each other, under normal circumstances, the circuit layer is required to have a large current carrying capacity, which should use thick copper foil thickness of 35μm ~ 280μm; thermal insulation layer is where the core technology of the aluminum plate, it is usually filled by a special ceramic special polymer, thermal resistance, excellent viscoelastic properties, the ability to heat aging, able to withstand the mechanical and thermal stresses.

The thermal insulating layer of the high performance of the aluminum substrate is the use of such technology, it has extremely excellent thermal conductivity and high strength, electrical insulation properties; metal substrate is an aluminum plate support member required to have a high thermal conductivity, typically an aluminum plate You can also use a copper plate (copper which can provide better thermal conductivity), suitable for drilling, punching and cutting conventional machining. The PCB material compared to the other material incomparable advantages. Power components, surface mount SMT public art. No radiator, greatly reduce the cooling effect is excellent, good insulating properties and mechanical properties.

Today's the PCB key application object, automotive PCB occupy an important position. But because of the car's special work environment, security and a large current and other requirements characteristics, high reliability, environmental adaptability requirements of PCB, PCB type of technology involved is also wider for PCB enterprises, this is a challenges; For vendors who want to develop automotive PCB market, this new market to do more to understand and analyze.

Automotive PCB special emphasis on high reliability and low the DPPM, then, our business has high reliability manufacturing technology and the accumulation of experience? Whether it is consistent with the future direction of product development? Process control, whether doing well in accordance with the TS16949 requirements? Whether it has to do a low DPPM? These have to do a careful assessment of the blind into the light to see attractive piece of cake, and will bring harm to the enterprise itself.

The following provides a representative part of the professional production car with some special practices of PCB enterprises in the testing process by reference to the vast number of PCB colleagues prepared:

1, the secondary test method

PCB production enterprise adoption of the secondary test method to improve to identify by the first high-voltage breakdown defect board rate.

2 bad board foolproof test system

Growing number of PCB manufacturers in bare board test machines installed the good board marking system as well as the "bad board error proofing box" in order to avoid human shortcoming. Board or a bad board a good board marking system for the test machine tested PASS board to be identified, has been tested and can effectively prevent the flow to the hands of customers. The bad board error proofing box is in the testing process, testing the PASS board signal test system output box opens; Conversely, test out the bad board when the case is closed, allowing the operator to correct placement of the tested circuit board.

3 PPm quality system

PPm (Partspermillion, parts per million defect rate) quality system PCB manufacturers began to be widely used. In many customers of my company, Singapore HitachiChemICal to its application and the results achieved in the most worth learning. The abnormal 20 people responsible for the quality of the online PCB and PCB quality abnormal returns statistical analysis in the plant. SPC production process statistical analysis method, every piece of bad board and each piece of returned defective board classification after statistical analysis, and combined with the the microsection aids analysis in which manufacturing processes to produce bad and defective board. According to statistical data, the destination to solve problems on the process.

4, the comparison test method

The models were compared using two different brands in different customer volume PCB testing and tracking PPm corresponding quantities, to understand the status of the performance of the two test machines, so choose the better performance of the test machine to test automotive PCB.

5, to improve the test parameters

The higher test parameters to detect such PCB strictly. If you choose a higher voltage threshold, increase the number of high-pressure reading leakage can improve PCB defect detection rate of plate. For example Suzhou PCB of a large Taiwan-funded enterprises to adopt 300V, 30M, 20 in Europe carried out test automotive PCB.

6, regular calibration of test parameters

Testing machine in the long-term operation, the internal resistance of the test parameters will be biased. Therefore need to periodically adjust the machine parameters, in order to ensure the accuracy of the test parameters. Test equipment in a considerable part of the large PCB enterprises are six months or one year for machine maintenance, adjust the internal performance parameters. Direction has been a vast number of PCB efforts with the PCB, but restricted by the many limitations of the process equipment, raw materials, since PCB hundred companies in the world continues to explore the methods to reduce PPm pursuit of "zero defect" car.

LED PCB switching power supply PCB design technology

Wed, 06 Mar 2013 08:02:39 +0000

LED switching power supply PCB design technology

- The physical design of the PCB board is especially important as the last link of the switching power supply design, if the improper design, PCB may radiate excessive electromagnetic interference caused by power supply job instability. To this end, each step requires attention to the following matters and to understand the reason of.
One component parameters established from the schematic to the PCB design process -> input the schematic netlist -> design parameter settings -> hand layout -> hand-wiring -> verify design -> review -> CAM output

Parameter settings adjacent conductor spacing must be able to meet the requirements of electrical safety, and in order to facilitate the operation and production, spacing should be as wide as possible. Minimum pitch is at least to be able to fit to withstand the voltage, the wiring density is low, the spacing of the signal lines may be appropriately increased, the high, low disparity signal lines should be as short as possible and increase the spacing, under normal circumstances will take the line spacing is set to 8mil.

The pad inner hole edge of the distance to the printed circuit board section can be greater than 1mm, so to avoid the processing pads defect. Smaller traces connected with the pad,, To pads and traces the connection between the design into a teardrop-shaped, so the advantage is that the pad is not easy from the skin, but the traces and pads is not easy to disconnect.

Three components layout Practice has proved that even if the correct circuit schematic design, printed circuit board design properly, will have an adverse impact on the reliability of electronic equipment. For example, if the printed boards two thin parallel lines in close proximity, it will form a signal waveform delays, reflected noise is formed at the terminal of the transmission line; interference caused not thoughtful consideration of the power supply, ground, cause the product performance degradation, therefore, in the design of printed circuit board when the correct method should be noted. Each switching power supply has four current loop:
(1) Power Switch AC circuit
(2) the output rectifier AC circuit
(3) current loop input signal source
(4) the output load current circuit

Input loop through an approximate DC current DC energy input capacitance charging, filter capacitor played a main the broadband energy storage role; Similarly, the output filter capacitor is used to store the high-frequency energy from the output rectifier, while eliminating the output load circuit . Important terminal of the input and output filter capacitor, the input and output current loop should be only from the terminal of the filter capacitor connected to the power supply; connection between the input / output circuit and power switch / rectifier circuit can not be with the capacitor the terminal directly connected to the exchange of energy by the input or output filter capacitor and radiation to the environment. Trapezoidal current of the AC circuit of the power switch and the rectifier AC circuit contains a high-amplitude, high harmonic components of these currents, whose frequency is much larger than the switching baseband, the peak amplitude of up to 5 times the continuous input / output DC current amplitude, the transition time is usually approximately 50ns. Two loops is the most prone to electromagnetic interference, so the power supply must be before other printing line wiring first cloth these exchanges loop, each loop three major components filter capacitor, the power switch or rectifier, inductor or transformer should be to each other be placed adjacent to the position of adjustment element as short as possible to make a current path between them. The best method to their electrical design of a switching power supply layout similar optimal design process is as follows:

Placed transformer
The design of the power switch current loop
Design output rectifier current loop
Control electric circuit connected to AC power

Design input of the current source circuit and an input filter design output load circuit and output filter according to the functional units of the circuit, all the components of the circuit layout to comply with the following principles:

(1) The first thing to consider PCB size. PCB size is too large, the printed lines long, the impedance increases, the decreased ability of the anti-noise, the cost also increases; too small, poor heat dissipation, and adjacent lines susceptible to interference. The optimum shape of the circuit board of rectangular shape, and an aspect ratio of 3:2 or 4:3, the components located in the edge of the circuit board, away from the edge of the circuit board is generally not less than 2mm.

(2) when the device is placed after welding, not too dense.

(3) as the center, around which the core element for each of the functional circuit to the layout. Components should be uniform, neatly and compactly arranged on the PCB, minimize and shorten the leads and connections between the various components, decoupling capacitors as close as possible to the device VCC.

(4) In the high frequency circuit, it is necessary to consider the parameters of the distribution between the components. The general circuit should be as the components are arranged in parallel. This way, not only beautiful, but also easy to assembly and welding, easy mass production.

(5) arranged in accordance with the processes of the circuit unit location of the respective functional circuit, so that the layout to facilitate the signal flow, and a signal as much as possible to maintain a consistent direction.

(6) layout of the first principle is to ensure that the wiring routability attention to the fly line connection in mobile devices, the device is connected relationship together.

(7) as much as possible to reduce the loop area to inhibit switching power radiated interference.

Wiring of switching power supply includes a high frequency signal, PCB on any printed line can acts as an antenna, and the length and width of the printed lines will affect the resistance and inductance, thus affecting the frequency response. Even if it is printed by the DC signal line will be coupled to the printed lines from neighboring RF signals and cause the circuit (even re-radiated interference signal). Should be as short and wide as possible, which means that you must be connected to AC current through the printed line designed printed line and connected to the other components of the power cord is placed very close. The length of the printed lines exhibit inductance and impedance proportional to the width is inversely proportional to the inductance and impedance of the printed lines. Response in the wavelength, the length of the printed line length reflects longer, the lower the frequency of the printed line is capable of transmitting and receiving electromagnetic waves, which can be radiated more RF energy. The width of the power cord from the printed circuit board the size of the current rent increase, reducing the loop resistance. At the same time, the power cord ground direction and the direction of the current, which helps enhance the ability of anti-noise. Grounding is the bottom branch of the to four current circuit of the switching power supply, and plays a very important role as a common reference point of the circuit, it is an important method for controlling interference. Therefore, the layout should carefully consider the placement of the grounding line, various ground mixed cause power job insecurity.

Ground design should pay attention to the following points:

Right choice of single-point ground usually filter capacitor common terminal should other ground point coupling only connection point to the current exchange places same a circuit grounding point should be as close as possible to, and the level circuit power supply filter capacitor should be connected at the ground point of the level, mainly on account of the various parts of the circuit back to ground current is varied due to the actual flow through the impedance of the line will result in a change in the potential of the circuit part and the introduction of interference. In the present switching power supply, the inductance between the wiring and device is less affected, and the circulation formed by the grounding circuit interference, thus using the point grounding, the forthcoming power switch current loop (in several devices ground is connected to the ground pin, several devices of the output rectifier current loop ground also received the ground pin of the corresponding filter capacitor, so that the power is more stable and difficult to self-excited do a single point in the common ground at the pick the two diode or a small resistance, in fact, connected in more concentrated at a copper foil.

As bold ground wire to ground wire is very fine, the ground potential change with the change of the current, resulting in unstable electronic device timing signal level, the anti-noise performance deteriorated, so make sure the ground terminal of each current as short and wide printed lines, try to widen the power and ground width, the best ground than the power line width, their relationship is: ground> power line signal line, if possible, the ground wire should be greater than the width of 3mm, the large area of the copper layer can also be used for ground with spend place on the printed board and the ground connection as the ground. When global wiring must follow the following principles:

(1). Wiring direction: from the welding face, the arrangement orientation of the element as much as possible to maintain and schematic diagram consistent with the wiring direction is preferably consistent with the circuit diagram of the alignment direction, due to the production process usually requires that various parameters on the solder side detection, it is doing so to facilitate the inspection, commissioning and maintenance of production (Note: refer to meet the requirements of the circuit performance and the whole installation and panel layout premise).

(2) the design of the wiring diagram traces to minimize turning, the linewidth Do mutations in the printing arc wire corner should be ≥ 90 degrees, and strive simple lines.

(3) is not allowed in the printed circuit cross circuit, may cross the line, you can "drill", "around" two solutions. That let a lead from the other resistors, capacitors, transistors at the foot of the gap at the "drill" the past, or from one end of the lead may cross a "wound" in the past, in the special case of how the circuit is very complex, in order to simplify the design also allows jumper wire to solve the problem of cross circuit. A single panel DIP elements located in the top surface, surface-mount devices located in the bottom surface, so in the layout of the time-line devices with the table mount devices overlap, but to avoid pad overlap.

3. Input and output to the switching power supply for low-voltage DC-to-DC, wishing output voltage fed back to the transformer primary, after, but also on both sides of the circuit should have a common ground reference in pairs on both sides of the ground respectively shop copper connected together to form a common ground.

Fifth, check

Wiring design is complete, you need to carefully check the wiring design complies with the rules enacted by the designer, but also need to confirm whether the rules established to meet the demand for printed circuit board production process, general inspection line, line, line and component pads, lines and the through hole, the distance between the component pads and the through hole, the through hole and the through hole is reasonable, whether to meet production requirements. The suitability of the width of the power line and ground, whether there make the PCB ground widened. Note: Some errors can be ignored, such as some part of the connector Outline on the frame, check spacing error; modified for each other traces and vias, copper must re once.

, Review PCB checklist, including design rules, layer defines the line width, spacing, pads, vias set, but also focus on review of the device layout reasonable, the power and ground network traces, high-speed The clock network traces shield, decoupling capacitor placement and connection.

Seven design output output gerber files Note:

a need to output layer wiring layer (bottom), silk screen layer (including the top screen and bottom screen), solder resist layer (the underlying solder mask), drilling layer (bottom), while also generating drill files (NC Drill )

b. set the silkscreen Layer, do not choose Part Type, select the top (bottom) and silkscreen the Outline, Text, Linec, set each layer Layer the Board Outline chosen, set silkscreen Layer Do not choose Part Type, select the top (bottom) and the Outline of the silkscreen Text Line. generating drill files, use PowerPCB default settings, do not make any change.

IV immersion electrode humidifier
Immersion electrode humidifier (immersed Electrode humidifier) is an electrode that is immersed in water, a large area as a terminal, with water as the heating medium, when transfer electrical current through the water, generate heat, so that the water boils, generating steam which is characterized low cost, easy to install and use but the accuracy is lower, replace the cylinder and the need for regular maintenance.
V. cool mist humidifier
Such humidifiers utilize a fan to force air through the absorbent medium in contact with water, the exchange to increase the relative humidity of the air. The characteristics of such a humidifier automatically adjust with the relative humidity of the air, the relative air humidity and low humidification large, the relative air humidity is high, low humidification; drawback is the low amount of humidification (approximately ultrasonic humidifier 1 / 5), and the noise with respect to the ultrasonic humidifier large, but this humidifier less energy consumption, and low noise.
, Commercial humidifier
Commercial humidifier is a cross between the middle between the civilian and industrial spray amount of humidification equipment.
Commercial humidifier should have the following characteristics:
1 medium commercial humidifier spray. Can not be too small, the commercial space hundreds of square meters, too small amount of humidification meaningless.
Commercial humidifier needs to work reliably. Commercial environment require a lower failure rate of the working.
Commercial humidifier to facilitate maintenance. Any commercial environment are long-term work, unable to maintain the equipment is not suitable for use.
Commercial humidifier should be as energy efficient. The long-term use of commercial environments, there is a strong demand to save energy.
5, the volume of commercial humidifier. Commercial environment in general compact volume of humidification equipment miniaturization tendency.
6 commercial humidifier water supply. Commercial environment is complex and diverse requirements of the humidifier water supply, water supply should be flexible and convenient.
Commercial humidifier suitable for mahjong room, chess room, KTV, beauty salon, hotel, family, entertainment, offices, banks, hospitals, schools, government agencies and other large indoor spaces.
Seven, oxygen bar humidifier
The the Oxygen Bar humidifier (Oxygen Bar Humidifier), also called the the oxygen bar empty net humidifier works through electrolysis the humidifier in the the atomized water while release pure substances - ozone (O3), O3 in water atomization process play the efficacy of disinfection of water quality, and with the a uniform the humidification fine mist spread to all corner of the room, to play the role of the Oxygen Bar humidifier release the clean air of pure substances - ozone (O3) is a powerful and well-known pure purifying agent in high purity water systems can continuously remove bacteria and viruses, the best method is to use ozone. Ozone (O3) is often used for drinking water purification, air purification, at home or in the field of medical sterilization, fruit and vegetable preservation, beauty care, ≤ 0.05PPM the ozone concentration in healthy non-polluting, better ensure humidification water clean, cleaner home air moisture .

Wed, 06 Mar 2013 06:47:38 +0000

Flexible display production need at least three years

Corning glass supplier says the iPhone screen, use the new Willow material of flexible screen production need at least 3 years.

Corning President James clay flat (James Clappin) said that the vendor has not yet developed fully USES the Willow glass products. Willow glass to be able to roll up like a newspaper, based on this kind of material can be developed a radian or flexible displays.

He said: "people can roll up glass has not been used, the user use means that the products currently have limitations." He said at the same time, corning has made a lot of effort, help large customers understand how to use this kind of glass can be rolled up. Google and other companies are developing wearable computing devices, so the glass material will have nowhere to go.

Clay said, this year, the Willow glass will be used in some simple products, such as flexible solar panel fence, and some touch panel behind the film. Last June, corning has been sent to mobile phones, tablet PC and TV manufacturers provides flexible glass samples. The company's chief financial officer James floors (James Flaws) said at the time, corning hope this product will go on general sale in 2013.

Google is currently developing computer embedded in the glasses, and plans to sale this product in 2014. But two sources said that apple has established a team around 100 product designers, such equipment is developing wrist, achieve the function of iPhone and iPad parts. Clay declined to disclose, whether corning had any contact with apple on this project.

Corning has 161 years history, the rapid growth of smartphone sales to promote the company's earnings growth. Corning, said the company was launched in 2007, the "gorilla glass is used in more than 1 billion devices worldwide. Corning sales gorilla glass for 33 electronic equipment manufacturers, including samsung and SONY. This kind of glass is used in more than 900 devices.

Last year, the gorilla glass sales rose 44%, to $1 billion. Corning CEO Wendell Wilkes (Wendell weekes), said this month it is corning company profit ability ranked second in history, and the fastest growing product.

Clay said, touch screen notebook demand rise will drive the gorilla glass sales faster growth. He said: "we sold the gorilla glass in many applications in mobile phone, but the size of the notebook is 10 times greater than a smartphone, 10 times area is large. The glass manufacturer sales according to the area computation, the bigger the size, the better for us."

Samsung or to buy a 3% stake the sharp negotiations are in the final stage

Wed, 06 Mar 2013 06:10:02 +0000

Samsung or to buy a 3% stake the sharp negotiations are in the final stage

Beijing time on March 6, according to foreign media reports, the two source familiar with the situation said on Tuesday, the south Korean electronics giant samsung is final talks with sharp, is likely to be the latter for about 10 billion yen ($107 million) investment, acquisition of a 3% stake in the Japanese company.

Sharp and other Japanese consumer electronics companies such as SONY and panasonic are in trouble, because it is facing fierce competition from the Asian rivals, including competition from samsung.

Sharp, a spokesman in Tokyo has not confirmed samsung investment plans, but also did not deny. The spokesman said: "this message is not the company has announced." In October, sharp, received a $4.4 billion rescue loan from the bank, but have to mortgage the multiple offices and factories in Japan. In addition, the company also has promised will lay off 10000 employees, and to sell some assets.

Prior to that, unnamed co-conspirators to negotiate with hon hai, hope the latter for investment. But according to sources, the Japanese company's recovery plan is unlikely to capital injection from hon hai precision will be included. Last December, chip maker qualcomm agree with the sharp invest up to $120 million. As part of the deal, said it would cooperate with sharp development of new energy-saving screen, the screen will be sharp's IGZO (indium gallium zinc oxide) technology as the foundation.

The camera PCB four points

Wed, 06 Mar 2013 03:49:57 +0000

The camera PCB four points
First, the maximum aperture
The true value of the maximum aperture performance in raising the amount of light in low light situations, so as to achieve the best exposure combinations. The shooting the landscape generally less requirement lens blur addition to a particularly dark place generally less demanding lens diameter. However, when the 70-200mm zoom lens retrofitting a 2x Teleconverter so telephoto focal lengths become 400mm AF auto-focus, it is best to choose the maximum aperture is F2.8 lens. The large aperture favor accurate focusing in dark conditions. With a large aperture lens to take pictures of people, even in low light handheld use of natural light shooting. In addition, the maximum aperture of the lens can bring faster shutter speed sports photography requires large aperture lens.
Another reason to require large lens aperture freedom to blur the background, but also to ensure the quality of blur. The maximum aperture F1.4 lens when stopped down to F2, the imaging quality of background blur quality are stronger than the maximum aperture F2 lens. Therefore, large-diameter lens was a stop of considerable value, any photographer should be adept at using this feature of the lens.
Second, the focal length
Select to pay attention to the first lens is the focal length of the lens, the focal length is actually viewing angle, focal length different perspectives are different. Addition, the user must be clear, I buy the lens What is the purpose? Shoot landscapes or shoot people and so on. As we all know, to shoot scenery is appropriate to the wide-angle lens, and shoot people suitably telephoto lens, so first decide what you want to buy the lens focal length according to photographic purposes.
Shooting landscapes focal lengths wide-angle focal lengths 24mm, telephoto focal lengths 200mm (are 35mm specification as a standard, the same below). , May be admitted to the scenery greatly broaden the scope of the standard zoom lens wide-angle focal lengths perspective of evolution from 28mm to 24mm larger. Generally shooting landscapes, the maximum aperture of the lens is not too high. If you mainly shoot landscapes, the choice of a zoom lens, wide-angle focal lengths 24mm basic suffice. For telephoto focal lengths, at least get a 200mm, 300mm or 400mm telephoto focal lengths is even more ideal, will greatly enhance the degree of freedom. Traditional zoom lens telephoto focal lengths more than 300mm, digital SLR is 450mm, focal length expanded 1.5 times, will feel more happy with them, the value of it is digital SLR. Now produced digital special ultra-wide-angle lens wide-angle focal lengths generally equivalent to 35mm size 18mm to 12mm, compared to 28mm focal lengths of 35mm specifications nearly expanded 1.5 times, so the landscape scenes around the shooting range greatly widened.
Photographing people focal lengths 85mm. 35mm specifications, photographing people basic criteria to select the lens to 85mm focal length. 85mm focal lengths portrait shot close to the screen shot medium format camera effects, sense of distance not only appropriate, but also the face of the person it is very natural, and the distance between the camera and the camera figures Basic can be maintained at the normal talking distance. 85mm focal lengths can be very prominent figures blur the background. In order to get a good blur effects, should choose a large maximum aperture of the lens. 85mm focal lengths on a digital SLR about 135mm, although the film the sense of distance of the screen seems a little weak, but the basic cause illness, so the focal length of the lens photographing people at least to about 85mm.
Shoot a 100mm macro lens enough flowers for the traditional SLR. 100mm macro lens and other times photography can flower looks great, but when of times photography or close-fold photography, etc., due to the focal length of a shallow depth of, prone to jitter, so measures to consider anti-shake when shooting. From this point of view, 50mm macro lens with digital SLR is easier to use.
Third, the close-up ability
Close-up lens is another focus after the focal length, maximum aperture. This is both the wide-angle lens, standard lens or telephoto lens. Well, close-up ability in the end how much would be suitable it?
First shooting landscape with wide-angle lens, close-up capability for wide-angle lens is almost no relationship, but when shooting flowers scenery vast landscape as the background, often put flowers looks bigger, in similar circumstances, the wide-angle lens, close-up ability it is very important.
50mm standard lens close-up capacity of about 45cm to meet the basic. However, the large aperture standard lens using the shortest distance photography, the lens extends, often there is a big aberration causing low quality, purchase and use of this is to have ideological ready.
Telephoto lens for shooting landscapes, not much requirements for close-up capability. However, if for photographing people or flowers, close-up lens is very important.
Fourth, expressive
The first note of a lot of people in the choice of the lens is the sharpness of this lens imaging. The photo use decisions need what kind of sharpness of the lens. High-priced high-quality lens for professional photographers, and just general photography, there is no need to spend a lot of money to buy high-priced quality lens. In addition, the image sharpness of the lens and aperture size is directly related to image sharpness will greatly improve when a lens is reduced from the maximum aperture two tranches.
The distortion is an optical phenomenon caused by the lens optical performance, each lens are impossible to distortion does not exist, and manufacturers in the production of the lens distortion correction, sought to control the distortion to a minimum. Lens distortion in general, there are three main: the wide-angle end of the zoom lens barrel distortion prone, the telephoto end prone pincushion distortion and barrel distortion correction for wide-angle end hats distortion. On the the lens status quo, the most prominent problem is the barrel distortion in wide-angle end, and buy as much as possible to choose the style of barrel distortion.
Backlit photography due to strong sunlight or other strong light source in the mirror repeatedly reflected on the screen to form halos and flares. This small part of the formation of halos and flares light not only not in the image on the screen, but also reduce the quality form a chaotic reflection in the mirror. In order to prevent this phenomenon, backlit photography must use the hood. The excellent lens taken in the manufacturing process completely prevent halos and flares process even in contrast backlit film is also very good.

The humidifier PCB humidification Notes

Wed, 06 Mar 2013 03:46:08 +0000

The humidifier PCB humidification Notes
According to the humidity requirements, we craft humidification and comfort humidification humidification in turn divided into two kinds:
1. Increasing emphasis on air humidity in modern industrial production and scientific experiment are increasingly high requirements, if the humidity does not meet the requirements, will result in varying degrees of adverse consequences, such as:
1 electronics factory, semiconductor factory programmed engine room, explosion-proof factory premises humidity requirements generally 40% to 60% of RH, if the relative humidity is not enough will cause static electricity increased, so that the decline in the yield of the product, chip damage, even in some explosion sites will cause an explosion, electrostatic bombardment "the harm is immeasurable, and easily generate static electricity when air humidity below 40% RH, While it has taken a lot of ways to remove static electricity, air humidity increased to more than 45% RH is absolutely valid.
2 textile mills, printing, film factory premises humidity requirements are generally very high, generally greater than 60% RH, such as textile mills humidity requirements are generally between 50% ~ 85% RH, Huang chemical segment to prevent electrostatic spinning station to prevent thenardite crystallization require high humidity, the moisture content of the cotton fibers is directly affect the fiber strength, in short, the air conditioning of textile workshop in order to ensure the relative humidity of the process requires. The lack of humidity will cause in the process of printing and film production color misregistration, paper shrinkage deformation paper adhesions, product quality problems.
Precision machining lathe, various measuring room humidity requirements generally between 40% ~ 65% RH, such as the finishing of precision bearings, precision scribing machine, mechanical measurement chamber, Electricity metering rooms, etc., if the lack of humidity will cause The accuracy of the processed products decreased distortion measurement data.
4 humidity requirements of the product coating plant is generally greater than 65% RH, if the lack of humidity causes the adhesion of paint on the metal or plastic decreased uneven painting, surface finish decline.
The 5 pharmaceutical plant, operating room environment humidity requirements of necessity and clean humidification, lack of humidity will cause the drug level decreased, the bacteria increased, wound healing and other issues.
In addition, cigarettes, cold storage preservation, food resurgence aging experiments, heritage preservation, gravity tests, protect decoration, convalescent centers and other places, the humidity is high, with the development of modern industry, the air conditioning works the humidification problem will become more important. Although in some southern humidification requirements very short time, and some are only 1-2 months, but as long as the process needs to ensure that the same quality of products, humidification problems must be taken into account.
Humidifier
2. Determination of people feel most comfortable ambient temperature around 25 ℃, relative humidity 45% ~ 55% RH range, low relative humidity can cause dry skin and itching phenomenon, appropriate relative humidity will make people I feel very comfortable, safeguard human health, and improve work efficiency. In addition, the right temperature and humidity environment is also conducive to the protection of the room decoration, to extend the life of the home improvement.
Humidifying method there are many and varied, but it is impossible to each humidifying form can satisfy all the humidification requirements, so according to the specific requirements of the actual engineering reasonable is very important to select a suitable humidifier! Reasonable choice humidifier from the wetting effect, equipment costs, operating costs, maintenance costs, security and other aspects into account, humidification This will not only meet the needs but not so wasteful, in line with the basic concept of modern production, life!

Humidifier humidification principle

Wed, 06 Mar 2013 03:38:45 +0000

Humidifier humidification principle
Humidifier home humidifier and industrial uses mainly divided into two kinds of types with a humidifier.
Household humidifier in the target market is generally using ultrasonic water atomization, and the atomization of water vapor blowing through the fan casing, thereby humidifier works Figure
To achieve the effect of humidifying the air, its electrical schematic diagram as shown in drawings. Mains after switching power supply, the output of two voltage 36V and 12V. 36V supply water vapor atomization module to .12 V supply fan. Circuit, D1, D2 are the water shortage lights and work lights; reed switch for liquid level detection switches; RT1 the mist size adjustment potentiometer. 02 core and its peripheral circuit ultrasonic generator circuit.
1.7MHZ frequency ultrasonic humidifier uses ultrasonic frequency oscillatory mist into the 1-5 micron ultrafine particles, through the wind-driven device, water humidifier
Fog spread to the air, the moist air and the associated negative oxygen ions, to fresh air, better health, to create a comfortable environment.
According to experts, the advantages of the ultrasonic humidifier, wet strength, uniform humidification, high efficiency humidification; energy saving, energy saving, power consumption is only 1/10 to 1/15 of the electric humidifiers; automatically balance of long service life, humidity anhydrous automatic protection; function of both medical atomization, the cold bath surface cleaning jewelry.
The direct evaporation type humidifier is also often referred to as pure type humidifier. Pure humidification technology humidification just used in the field of new technologies, purified humidifier by zeolite evaporation technology, to remove calcium and magnesium ions in the water, completely solve the question of "white powder".
The thermal evaporation type humidifier, also known as electric humidifier. The working principle is heating the water in the heating body to 100 degrees to create steam, steam out fan. Electrically heated humidifier is the most technologically simple humidification, the disadvantage is that large energy consumption, not dry, lower safety factor, the heater is easy to scale. The market outlook is not optimistic. Electric humidifier supporting the use of general and central air-conditioning, and is generally not used alone.
Compared to the above three, electrically heated humidifier use "white powder" phenomenon, low noise, but power consumption, easy to scale humidifier; pure type humidifier "white powder" phenomenon is not scaling power having an air circulation system, it is possible to filter the air and kill bacteria.
The ultrasonic humidifier humidification intensity and even small power consumption, long service life, both medical atomization, the cold bath surface cleaning jewelry and other functions. Therefore, the ultrasonic humidifier and pure humidifier is recommended the product of choice. [1]
Five characteristics:
A cabinet made of stainless steel, atomized movement.
2. The modular integrated, single movement independent replacement chip.
3. No mechanical operation, comes with a water level protection switch, reliable operation.
4. Atomization characteristics of high efficiency, the whole diameter of the aerosol particles only 1 ~ 10μ, gasification efficiency up to 100%.
5. With automatic replenishment \ water protection and overflow function, optional drainage system and water softener device achieve calcification white powder pollution requirements.

Vacuum cleaner
Help edit Baike card
Vacuum cleaner electric vacuum cleaner has a history of 100 years, for many people, it has become an indispensable household equipment, for obvious reasons. The current control the motor running. Attached to the motor fan, the fan blades having a certain angle, like an airplane propeller. When the rotation of the fan blades, the air has been pushed to the exhaust port. When the air particles is pushed forward in front of the particle density of the fan will increase and a corresponding increase in air pressure, and the the rear particle density of the fan decreases. The pressure generated by the fan rear drop match suction beverage pipette the same pressure drop. The fan behind the pressure is lower than the pressure of the outside of the vacuum cleaner, the ambient pressure. This suction, ie a partial vacuum inside the vacuum cleaner.

Principles and structure of the vacuum cleaner
Edit this paragraph vacuum cleaner scientific inventions Herbert Booth 1901
Who in the 19th century inventor trial will suck dirt machine. Most machines use a hand to start folding bellows. Some machines are manufactured, including the success of the "Daisy" type. But they are not labor-saving, because of the need for two people to operate a ventilation box, an alignment interface.
British engineer Herbert Booth, manufactured in 1901, the first vacuum cleaner. It has a gasoline engine, and is the first station that has an efficient filter of the vacuum cleaner, i.e., it has a retaining dirt filter cloth, so that the clean air back to the room. Large bulky device that is the one intended to be used in the factory.
Booth vacuum cleaner left a deep impression on American inventor J Murray Spence Grenoble. In 1900, he produced a small vacuum cleaner for home use, and design rights sold to William · H · Hoover called saddlery manufacturers.
In 1908, Hoover set about producing a small vacuum cleaner, and the results prove that it is very popular with people welcome. Since then, the vacuum cleaner on the "Hoover" brand known.
Is a 19th century design of the vacuum cleaner with a steam engine for power. Even if used in industry, such a large machine nor the General Assembly a popular opportunity.
Edit this paragraph the true air cleaner principle of modern vacuum cleaner parts vacuum pump, dust bag, hose and a variety of different shapes spout. Inside the machine with a motor-driven blower, powered high speed operation, the vacuum cleaner is formed inside the instant vacuum, the internal air pressure is considerably lower than the outside air pressure, dust and dirt in the air pressure difference under the action of the airflow into the vacuum cleaner inside the drum, and then through the filter of the dust bag, grime left in the dust bag, purify the air escape into the room through the motor re-played cooling motor, purify the air.
Edit this paragraph cleaner development status began in the late 1990s, China cleaner sales increased rate of 38% annually. Vacuum cleaners not only function more and more, the appearance of increasingly beautify its price is getting cheaper, by a lot of people's favorite. China vacuum cleaner market mainstream brands, Haier, Philips, Electrolux, LG, Sanyo, dragon, beauty, puppy, Rowenta, Panasonic and others.
