What is the future of chip technology? We are at the edge of an era where a chip might have to calculate 1,000 trillion operations per second. The logic for these future chips will be fundamentally different than what is applicable in today’s mobile devices and computers. However, chips with the necessary performance may still require billions of transistors.

That is where QuickLogic’s Eclipse technology comes in. IEEE published our original breakthrough as one of “the top 10 coolest inventions of 2009”. The unique transistor structures called unibody transistors pack billions of high-performance switches into a single chip. As a result, these switches are smaller than today’s 10nm and 7nm switch transistors yet have the same functionality.

Meanwhile, QuickLogic has developed numerous innovations enabling our technology to compute at unprecedented speeds while keeping power consumption. These include eliminating the need for a special purpose “logic blocks” dedicated to specific functions like multiplying or dividing numbers. The result is a more efficient processor that uses the same number of transistors to calculate simple operations like addition and multiplication to carry out highly complex tasks.

Why would you want a computer which can do simple operations at 1,000 trillion calculations per second? For one thing, this kind of computing power will enable our devices to run real-time artificial intelligence. Additionally, we anticipate that such chips may ultimately replace today’s computers in some applications because they will easily handle data manipulation and streaming tasks.

There are also more mundane uses for such performance. To illustrate, consider the data storage problem: storing all the information on the Internet requires 5 million petabytes, roughly 5 million gigabytes. While this is a lot of data storage, using a chip to process it all in real time would save a lot of money and space.

Why is this technology essential?

Today’s chips have billions of transistors that are all physically connected. While this arrangement is suitable for how they are helpful in computers and mobile devices, it cannot be scaled to support our expanding needs’ computing power and capabilities.

Right now, many computer scientists worry that Moore’s Law may be ending, but this doesn’t mean we will stop developing new technologies because we need more performance out of our transistors. Instead, engineers like Rayming PCB & Assembly will continue to innovate. As a result, we predict that they will have developed new ways of building chips that use the same metal or silicon foundries that produce our present chips within a few years.

What are these new technologies? First, we think they will involve a nanoscale and molecular-sized architecture, as demonstrated by researchers at Harvard University and The Wyss Institute for Biologically Inspired Engineering in Boston. As a result, this architecture will enable us to pack more transistors onto the same chip, relying on devices built from single molecules instead of individual transistors.

But nanoscale innovations don’t just change how transistors are necessary. They may also change the way each transistor works. For example, recent research at IBM and The University of Texas at Austin shows that carbon nanotubes hold the promise to dramatically improve chip performance by using them in place of silicon. In addition, this can combine with many other innovations we cannot foresee today in the quest for increased computing power and capability.

In what other ways has QuickLogic innovated?

QuickLogic’s Eclipse technology depends on a manufacturing approach called silicon on insulator or SOI. This manufacturing process enables the insulation of all transistors from the chip’s silicon substrate, a significant advance that would not be possible without SOI. The result is a chip with billions of high-performance transistors built with the same materials used in today’s chips. In addition, this technology has created 3 billion transistor chips with operating speeds of 2.5 billion instructions per second. In addition, the Eclipse family includes a variety of chips with different performance characteristics and customized designs.

The company has set its sights on developing a silicon-based solution to the “big data problem.” They are using their Eclipse technology in conjunction with carbon nanotube technology which will provide a way to build systems that can process the enormous amount of data and information that is forecast to come online in the coming years.

More specifically, QuickLogic is working with partners to develop new approaches for building memory and processing capability into chip designs. Using the Eclipse architecture and carbon nanotube technology, these new components will enable higher performance and power efficiency. In addition, QuickLogic is utilizing its industry leadership in silicon on insulator capabilities to allow a new generation of products for data storage and processing.

The company’s founders, who have been focusing on transistors for the past 20 years, are now applying their skills in semiconductors to continue developing more efficient ways to manage information. As they work to advance the industry, they build an ecosystem of partners. As a result, they’re creating new products designed to meet users’ shifting needs, from mobile applications and cloud computing to the Internet of things (IoT) systems.

Where does the QuickLogic Eclipse Family play a role?

QuickLogic has designed and delivered chips that use our Eclipse technology to date. So, these chips have been used in more than 60 products, from high-end computer servers to embedded systems for applications like military drones and industrial equipment.

As we look to the future, their goals are to develop new Eclipse technology with higher performance, which will require more innovative transistor designs. Additionally, they have also built a broad ecosystem with partners working with us to develop next-generation computing solutions, including communications and consumer electronics companies. Since the company’s founding ten years ago, QuickLogic has been a pioneer in developing new kinds of chips, which will be essential for the future of computing.

How can cables be weatherproofed for outdoor use?

Specialized jacketing materials like Teflon resist weather effects. Drip loops allow water to run off. Sealing connections prevents moisture ingress. Proper installation avoids water wicking into cables.

How are they made?

There are many types of RF cables. They consist of various materials, including copper, glass, and plastic. Some cables transmit RF data, and others send audio and video signals. The type of cable you choose depends on how your station will handle different signals and protocols. When designing a station’s physical layer, you need to use the ISO recommendation for recording data through your cable.

What are they used for?

The main purpose of RF cables is to connect two or more pieces of equipment. They are beneficial in radio, where the signals travel through the air and then connect to an antenna. You use them on TV to create a signal from your antenna to the television. It then bounces back from the antenna pcb again for other TVs to receive. We use them for military purposes on many satellites that transmit information through space.

What do they look like?

We make RF cables from various materials, but they all have qualities that make them similar. They have to be resistant to radiation, like the signal traveling through them. They must also be light and flexible to avoid problems during transmission or receiving. The best RF cables can also withstand extreme temperatures and pressures during transmission. The cable is usually gold-plated to ensure a tight connection, which increases the range and performance of the wire.

How RF cables work

All RF cables have specific characteristics that make them effective ways to send data. The type of cable chosen depends on how the station sends and receives data. RF cables can be a few inches long or as long as 50 miles. The ability to send data over long distances is essential when sending live video from a stadium or concert hall to millions of people. Some cables are glass and plastic, then fired into steel powder. It creates a cable that can handle high temperatures and radio waves. All you need to know about RF cables is how we make and use them. Understanding the physical layer of a station is essential in designing an efficient protocol.

In an RF transmission, it’s critical to have a cable that can pass a signal along without getting damaged. In the end, all you need to know about RF cables is what they do and how they accomplish it.

Benefits of RF Cable

1. To transmit information over long distances:

In the case of RF cables, they connect a transmitter and a receiver. The transmitter emits electromagnetic signals, and the receiver receives them. Data can move through walls or even through wires, but with the help of an RF cable, the information can travel very far.

2. To create a secure connection:

In general, your computer may not want to share personal data with another device. For example, it happens when sending sensitive information such as credit card numbers over an open network Wi-Fi connection.

3. Provide a secure connection between two devices:

The purpose of an RF cable is to provide a secure connection between two devices so that no one can access or change the data in transit.

4. Use in transmitting TV signals and radio waves:

RF cables are usually attached to a device capable of broadcasting and receiving signals. Radio waves move through the cable to the transmitter, which sends these signals to a television or other device.

5. RF data transfer:

We use RF cables to transfer data from one device to another. They pass the signal from one device to another through a physical connection to transmit and receive data over long distances. This way, there will be no need for an extra power supply.

6. Provide a stable connection between two devices:

While the connection may not be secure, the data can still move without interference or transmission breakdown.

7. The protection of the cable against outside radiation is critical to transmission:

We usually make RF cables using copper wire, which helps protect devices against outside radiation. In addition, copper is a very resilient material, and it is also resistant to corrosion.

RF Cable vs. Coaxial cable

A coaxial cable is a type of cable used for radio signals. It acts as a transmitter to send radio waves and acts as a receiver to pass through the signals coming from other sources. We also use it to connect one device to a system. RayMing PCB & Assembly make coaxial cables of copper, a very efficient conductor of electricity.

The difference between a coaxial cable and an RF cable is that a coaxial cable is helpful for just transmitting radio signals. It cannot send data using RF or other types of electromagnetic waves. So the only distinction between the two cables is that they serve different purposes, but they consist of the same materials.

It is essential to use RF cables to transmit radio waves because they can pass through walls and other conductive materials. It is also crucial that you use a high-quality copper cable, the material used for coaxial and RF cables.

Another type of cable that we use for transmitting radio waves is an optical fiber cable. An optical fiber is a type of cable made of glass, which makes it very durable and light in weight. In addition, it can carry a considerable amount of data because it has a high capacity for data transfer, which makes it very efficient.

When you use RF cables to transmit data over long distances, the range can be as low as 10 meters and varies depending on the quality of the connection.

The Difference Between RF Cable and HDMI Cable

A high-definition multimedia interface (HDMI) cable transmits high-definition video, audio, and other data. It is ideal for use in theater systems and home entertainment systems. The main difference between an HDMI cable and an RF cable is that HDMI cables can transmit various types of media data. RF cables can transmit radio signals. RF cables cannot transmit audio or video data to the same HDMI cables because they do not support digital signals. The types of data transmitted through an HDMI cable may differ from one manufacturer to another, but it can support up to eight audio channels. HDMI cables are usually essential in connecting devices such as computers or television. An RF cable can transmit radio, television, and military systems. But you can also send data over long distances. It doesn’t allow for audio or video information transmission. But it is still possible to do it using other means.

It is essential to use an HDMI cable to send audio and video data because it is a less expensive alternative to other cables. When using an HDMI cable, you only need to make sure that you buy a quality cable that transmits high-quality signals. We can also use it for sending Ethernet signals.

There are many different types of RF cables. They have different designs depending on the purpose they serve. However, they all have something in common. These cables can transfer data over long distances irrespective of their other materials. It depends on the device they are being used to connect. The most common types of RF cables include telephone and coaxial cables. A telephone cable connects two devices through a physical connection. A coaxial cable connects two devices wirelessly.

Specification of good RF Cables

1. Impedance Specification

It is essential to buy an RF cable with an impedance specification that matches the impedance of your cable. Impedance can define the resistance of your cable towards the flow of alternating current. We measure it in ohms. The most commonly used values for impedance are 50 and 75 ohms, but you can also find cables with a value higher than 100 ohms. A standard RF cable impedance depends on the signal’s frequency.

2. Frequency Response

We use frequency response to define the bandwidth of your cable. It determines the rate at which your cable can transmit the signal without distorting or interfering with it. Depending on how fast your signal needs to move, we measure it in hertz, kilohertz, and megahertz. The most commonly used values range from 30Hz to 4000Hz. But some cables can work even at higher frequencies such as 10MHz and higher.

3. Phase Stability

We use phase stability to define the phase shift in your cable. If there is no phase shift, it means that your cable can handle data without distortion. Phase stability of a standard RF cable does not change with time.

4. Shielding

It is essential to use a shielded cable to protect digital signals from interference. It usually consists of copper wires or conductive materials suitable for transmitting radio signals. However, they are not always made of copper because they would be too heavy and difficult to work with. Some shielding consists of aluminum or aluminum foil. We can use it with an antenna wire. They prevent unwanted electromagnetic radiation from moving through the cable.

5. Attenuation Specification

We use attenuation to define the energy loss in your cable over a particular length. The main components that cause attenuation in your cable are the cable material’s resistance and capacitance. We can express it in DB/100m or pico-watt per meter. The most commonly used values are 0, 1, 2, and 4db/km, depending on how fast your signal needs to move. But it also depends on how long the cable must be.

6. Power Specification

We use power specifications to define the maximum power your cable can support. We measure it in volts and watts. The most used values are 0, 2, 6, and 12 volts, but you can also find cables with a value higher than 50 volts. Wide ranges of RF cables are available with different power specifications.

7. Temperature Stability

It is essential to buy an RF cable with a temperature stability specification to use it in different conditions and temperatures. Temperature specifications are in dB/°C, where we define the -10 dB as a standard value, while we use the 0 dB to define how we can lose little energy.

8. The quality of the picture

The quality of the picture depends on various factors. For example, if you buy a cable for transmission through a digital video recorder, you should look for the highest image quality possible. However, you need it to send television signals through a coaxial cable connecting two devices for good image quality. The price is more critical when choosing an RF cable because they determine the transmission speed of your signal.

9. External interference

Suppose you will be using your cable in an external interference source environment. In that case, you must choose a cable that can handle the interference and not let it go through the wire. If you don’t need the cable to be connected all the time, using a cable type that is less likely to break or cut out may be a good idea.

10. The quality of the audio

It is essential to make sure that you buy a cable with good audio quality so that the sound of the source device is clear. Your television will not have as effective a picture if there is interference in the audio signal. The RF cable is very useful for transmitting audio, but it doesn’t allow you to do anything else. It cannot provide additional power for the sound it transmits. Therefore, the audio quality depends on what you are using to receive the signal.

11. Signal Types

If you are using a cable to transmit a signal of a specific type, it is essential to choose a cable that can handle the type of signal. For example, if you are recording digital television signals, your cable has to send these signals without distortion. We use cables for different purposes, and it is essential to understand how we can use each type. For example, RF cable can transmit HD signals, but not all RF cable types can.

12. Accessibility

It is essential to buy a cable that is accessible because it will be easier for you to install and use it. Specific RF cables are not too accessible, and we can use them only if you have the correct equipment to install them. You should understand these types of cables and use them properly. But if you find an RF cable with all the specifications listed above, it should be suitable for your needs.

13. Diverse needs

There are many types of RF cables that we can use. You must make sure that it suits your needs and the type of signal you are transmitting over your cable. You must know what type of signals you need to transmit before buying an RF cable because not all cables can handle all kinds of signals.

14. The covered distance

You must make sure that you buy a cable that can transmit signals between different distances. It is essential to buy an RF cable that can easily send signals over longer distances because it is more cost-efficient.

15. Cable installation

We usually install RF cables manually, which is not easy to install. If you do not have the right tools, it will be very hard for you to install your RF cable. This is without causing damage to the device or the signal it transmits over a distance.

16. Noise

Most RF cable types have noise, but it depends on how much noise the cable can handle. If you cannot install your cable correctly and use it efficiently, this can also be a problem. The best thing to choose is a cable with very low noise that provides clear audio signals with no interference.

17. Speed in data transfer

The speed of data transfer depends on the cable type you are using. Your cable can transmit data signals at a very high speed, but only if it is a good quality cable with the correct installation. You should buy a cable that can support the transmission of your signal. It does not cause any distortion, resulting in decreased data transfer speeds.

18. Cost

The cost of an RF cable depends on the cable’s length and the other specifications it has. You should be careful when buying an RF cable because you can easily spend a lot of money on your purchase if you buy a not suitable cable for your needs. If you find a good quality, long length of RF cable, it can be costly. But if you find one short and does not have any extra specifications, it will probably cost less than others.

19. Cable terminals

Choosing a cable with the right terminals for your device is essential. If you do not buy the right type of cable, then it will be hard for you to connect it to your device and use it. Therefore, you should check your device specifications before buying an RF cable to ensure that we can use it with the terminal type of your device.

20. Potential loss of the transmission

You should ensure that the cable does not lose any transmission signals when transmitting them over a certain distance. Of course, different factors can cause the loss of signals. But you should choose a cable that can transmit your signal and ensure that we do not lose signals in the transmission.

21. Multiple functions

You should choose an RF cable with more than one terminal to make it easier for you to connect it to your device. In addition, purchasing a dual-type of cable will make it easier for you to connect the cable to your device and use it efficiently.

Cable for Wireless Transmission

A cable with the right specification can transmit signals over a certain distance without distortion.

If you want to transmit signals over extended distances, then you must choose an RF cable that is long enough to cover the distance. Some RF cable types can be costly, but they are usually long and can transmit your audio and video signals over a large area.

The best thing about these types of cables is that we can use them in interior homes and outdoors.

Application of RF cables

There are various types of RF cables with different combinations of features. However, the features are essential, and you should check that we can use the cable for your application.

1. RF equipment in medicine and healthcare

Frequently Asked Questions

What is the most critical SMT process step?

Reflow soldering is generally considered the most crucial step since this permanently forms the solder joints attaching components. The profile must be optimized to suit all component requirements.

How small of components can be soldered with SMT?

SMT can reliably solder extremely small components like 01005 passives, microBGAs, and even microchips with tolerances down to 15 microns or below with advanced techniques.

What are common SMT defects?

Insufficient solder and open joints, bridges and shorts, tombstoning, skewed parts, solder balls/beading, heat damage, missing components, bent leads, are examples of potential SMT assembly defects.

What is the key advantage of SMT vs through-hole?

Higher component density, miniaturization, and suitability for automation give SMT a density and throughput advantage. However, through-hole assembly can utilize lower cost components and enables easier rework.

How can SMT solder joint quality be inspected?

Automated optical inspection and 3D SPI immediately after soldering can catch many defects. For internal inspection, X-ray laminography provides detailed 3D views of hidden solder joint quality.

To achieve the best electronics, one needs to solder. This process is often done with a soldering iron and leads to success if done properly. But how do you know how to solder? Here, I will introduce you with the SMT soldering process, including a step-by-step guide on how to put together a piece of electronics.

What is SMT soldering?

SMT soldering is the process of soldering electronic parts onto a circuit board, which is mostly done by hand. SMT is an abbreviation for “Surface Mount Technology”. This means that we do the solder assembly without a soldering iron, but instead with a machine called a “solder reflow oven”. The steps and materials used to SMT solder include the following.

When Is SMT Soldering Used?

SMT soldering can be helpful in many ways, including using as a hobby or at work. The use of SMT soldering will increase your knowledge in electronics and electricity. It’s also a good way to learn how to solder when you are starting out.

The reason SMT soldering is helpful at work is because of the low cost and high speed when producing the products.

What are the parts of SMT soldering?

There are two key things you need for SMT soldering: a circuit board and electronic parts.

For the circuit board, it is essential to use a silk-screened PCB (Printed Circuit Board) with plated holes (not tin). Usually, this type of circuit board can go for $1~$3 dollars in local Makerspace or online. To further save cost, you can also make your own printed circuit board, by drawing your circuitry on copper foil. Another option is to use a copper-clad board, which looks like a thin sheet of copper. It is acid-etched or sand-blasted with holes and traces.

For the electronic parts, you can find them online easily. For example, Rayming PCB & Assembly has a wide range of SMT parts at reasonable prices. Other places include eBay or Amazon. You should be careful when choosing these parts, as there are some which help specifically in prototyping and we cannot use in production parts.

Stuff you need

Before you start, you will need:

A soldering station

This is the current state of art in electronics manufacturing. It consists of a hot air furnace that heats up solder, a soldering iron that allows heating of the pasted joint, and a soldering tip which will melt the solder. The key to using a soldering station is to heat up pieces separately and avoid overheating them. You can use either the temperature mode or the time mode.

Some solder

This is the main ingredient in recreating this process. Solder consists of tin and lead, which are both an alloy with silver. Solder is normally a bit cheaper than other types of welding materials, and it has a better melting point than steel.

A soldering iron

This is the current state of art in electronics manufacturing. It consists of a hot air furnace that heats up solder, a soldering iron that allows heating of the pasted joint, and a soldering tip which will melt the solder. The key to using a soldering iron is to heat up pieces separately and avoid overheating them. You can use either the temperature mode or the time mode.

A piece of circuitry

An electronic circuit board is usually printed with various layers of metal with holes thats are full solder to connect to all the parts together. Circuit boards have a variety of shapes and sizes, depending on their function. You can use any type of printed circuit board; I will show you how to make a simple LED circuit board here.

A circuit diagram

There are many ways of using electronic components. Each design has its own merits, but most printed circuit boards require a schematic to read the connections of the wires and where they will connect to the solder. The circuit diagram is often presented as numbers on a grid.

Make SMT Soldering:

Step 1: Preparation

Assemble your tools appropriately (soldering iron, solder iron etc.) (see image below for more details). We must place solder in a temperature safe container to avoid damage from heat and oxidation once it becomes molten. Then find an area to work that is free from distractions. We can do this in the garage or workshop.

Step 2: Preparation of copper board

Find a copper board with the right size and shape for your circuit design. For example, a standard breadboard is good for prototyping, but if you want to make something more complex, you should use an integrated circuit board (or “chip” board). Chip boards are more expensive than breadboards, but it’s often easier to solder components on them because there are less wires that need to connect. For example, SMD LED soldering requires a chip led. We use solder paste here as well as it helps in stabilizing joints and making them watertight.

Step 3: Mixing of the solder paste

To mix the solder paste, first make sure that you switch off both of your soldering iron so you do not burn yourself. Remember, solder paste is extremely hot when it comes out of the nozzle. If you have a refillable hard solder gun, you can use the syringe to fill up some solder paste and simple push it down into a microwave safe container.

However, if you have an integrated circuit laser gun, make sure to screw off the tip off with a screwdriver before attempting this as it will burn your fingers. In this case, you will need to melt the solder paste first in a microwave or a small pot then mix it with the solder. It is best to hold your soldering iron with one hand and mix with the other as it is hot and can cause burns. After mixing, use a clean spoon or spatula to help melt the solder so that your circuit connects correctly.

Step 4: making SMT

Now we are ready for action! Switch on your soldering iron and put it on temperature 40°C~45°C. Heat up several pieces at once. Solder melts at 113°C. So, you must heat up several parts simultaneously. If you place them too close to each other, they will melt and you will have difficulty in moving the remaining parts.

As a test, take one of the parts and melt it on the tip of the soldering iron. If it is solid enough, then you can move on to more parts. If not, repeat until all your parts merge together.

Once you have all the parts joined, then use a piece of solder to connect all the pieces together. Take some time to test your work and check for any solder connecting to the iron. If so, remove by placing more solder on the joint.

Using this process, you can make your prototype. It does not require much skill, but it does take some time and patience. If it is your first time, it is probably best to make one part at a time and check for errors. The next step to making your own product using SMT is how the solder paste comes from the gun onto a pad. This video guide below will show you how to do this:

Conclusion

In this project, you have seen how you can use the basic components and simple soldering to make your own low cost PCB board. In addition, you have learned how to solder using a hot air soldering station and how to solder using an integrated circuit laser. You will also know the main ingredients in recreating the process of reflow soldering.

The advancement in the PCB industry has resulted in the recent development in PCB material. Today’s PCB materials are designed with great functionality and high reliability in mind. Shengyi PCB materials are examples of these. When it comes to quality, Shengyi is the right PCB product to opt for. In this article, we will be discussing one of Shengyi’s highly reliable PCB materials. The main focus here is the Shengyi SF305

What is the Shengyi SF305?

Shengyi SF305 is a halogen free PCB laminate with great thermal and electrical properties. Also, this PCB material adheres to the UL94 V-0 flammability standards.

The Effects of Heatup Rate and Pressure in Isola FR406 Lamination

The heat-up rate plays a crucial role in Isola FR406 resin systems. Therefore, it is important to regulate the rate of heat-up during multilayer Isola PCB fabrication. It is crucial in controlling the temperature rise rate via the flow period. This period starts from when resin system begins to melt and when it reaches a high viscosity.

The resin system may not flow well when the rate of heat-up is slow. Meanwhile, if the rate is fast, there might be uneven flow. Slow heat rise can result in high melt viscosity. Therefore, the resin may not be able to flow around the copper structure. Fast rate of heat-up results in higher FR406 resin flow.

Pressure can impact Isola FR406 lamination. When there is low pressure, this PCB material may feature poor interlaminar bonding. Also, it might have low-pressure areas that feature inadequate resin flow. The solution to this is to increase the pressure slightly. You can also adjust the heating rate to open the lamination window.

Also, the inner layers might experience distortion when the lamination pressure is very high. Also, high pressure can lead to glass knuckles crushing against inner layer’ traces. The heat-up rate is important since general flow depends on the resin melt viscosity. Also, it depends on the lamination pressure. The heat rate determines the melt viscosity to an extent. Therefore, it is ideal to keep a baseline heat-up rate of 10 °F for each minute.
