Printed circuit boards are now more crucial than ever due to their excellent properties. Today, you cannot think of developing consumer electronics without PCBs at all. However, it is obvious that the PCBs are building blocks of futuristic electronics on all counts.

 It means these have to be faultless as well. Or else they will fail to let the electronics perform in their natural state. If you are reading this post, you must be coming from a technical PCB background. 

Assuming this, you know that PCBs have several important components that render them different features. One of them is surface finish. It is like a covering that is present between a regular PCB and all of its components.

 There are two highly important roles of surface finish for PCBs. Number one is to secure the copper components, and number two is to create enough room for soldering these components with PCBs. 

There are different types of PCB surface finish. We are going to have a look at two common types called, OSP and ENIG, in this post. 

OSP Finish

An OSP is a natural and fine form of surface finish used for PCBs. The OSP comes in a natural state and does not include toxins, chemicals, and artificial additives. Now, the natural form of OSP makes it important for reducing corrosiveness. 

OSP surface finish is also eco-friendly. You can even use OSP with RoHS applications. Keep in mind that OSP includes water and develops a smooth surface for the components assembly of PCBs. 

Besides, it is a budget-friendly surface finish, and many manufacturers prefer to rely on it due to its exceptional qualities. Sometimes, even using a HASL cannot yield fruitful results. However, OSP saves you from any sort of hustle because it is a great substitute for HASL for PCB surfaces.

 Now that you know well about OSP, its time to hop onto the typical process it follows through this 6-step guide:

1. Cleaning: The process begins with cleaning the PCB’s surfaces in case oily residues, solder fragments, toxins, and corrosive chemicals are present on them.
2. Topography enhancement: The next step is to etch this surface which will solidify the connection of PCB and OSP itself but make sure to etch the surface with an optimum pace. 
3. Acid rinse: Now rinse the PCB with sulfuric acid after you have completed the etching step. 
4. OSP application: Once you have rinsed the PCB with sulfuric acid, you are good to go with applying the OSP to the PCB surface.
5. Deionization rinse: The OSP that you have just applied on PCB is ionized, which is perfect for assisting in the soldering step of PCBs. 
6. Dry: The last step is to completely dry the OSP layer to avoid problems. 

Downsides of OSP surface finish:

• It might not overcome dents and impressions
• The OSP can sometimes create a negative impact on soldering
• OSP does not promise longer shelf life as compared to other types 

Common uses for OSP include:

• Fine pitch devices: OSP does not involve pad and ridged surfaces, which makes it perfect for utilization in fine pitch applications
• Server boards: OSP is a reliable option to choose when it comes to server boards that work on a higher frequency
• Surface mount technology (SMT): OSP can easily serve well for the SMT PCB components, saves time, and offer quick assembly 

Advantages & Disadvantages of OSP Finishes 

Advantages

· Lead-free

OSP is an organic type of surface finish. The best part about its organic nature is that it is more eco-friendly than other types of surface finish present, like HASL, which creates an adverse impact on the environment. 

· Cost

It is an affordable to go for. OSP does not need high-end and rare materials for processing the PCBs. Due to this, it is accessible to most PCB producers at a much lower price. 

· Flat PCB surface finishes.

The texture of the OSP surface is flat and smooth. It means OSP will allow fine regulation of congested and sensitive PCB components. Unlike HASL since it interferes with the performance of PCB parts. HASL interacts with residues, fragments, and air particles and also locks the solder paste within the system. 

· Simple process

The process of OSP application is not extensive. It only involves six steps that are easy to carry out. It means technicians can perform OSP easily and quickly without any fear of mishaps and complications. 

· Repairable

The OSP is a repairable surface finish. Now what does “repairable” mean here? The repairable nature of OSP means if it chips off from any area, you can fix it. Also, if the finish gets damaged due to any reason or if you want to add more solder with the OSP, it is possible. 

Drawbacks

· Limited to RoHS compliance

If you are considering OSP, then keep in mind that it only fits well with RoHS applications. The substances like cadmium and mercury perform perfectly with OSP. Due to this reason, OSP is useless to use for external applications other than RoHS. Therefore completely relying on OSP for other applications is not recommendable. 

· Environmental impact

There is no doubt that OSP does not need lead. But it does use some solvents and chemical substances that are not healthy for the environment. The cleaning step of the OSP application process leaves excessive dirty water that can lead to polluting the environment through water-borne diseases as well. 

· Sensitive

OSP is not suitable for exposure to extremely hot temperatures for long periods of time. The OSP can completely chip off from the PCBs. It means the boards need to be re-processed, and it will be a lot of time-consuming.

· Short shelf life

All the surface finish types that involve water have a small shelf life. It means it will get expired and be useless after two months. Now, if you want to use OSP, then use it within two months of its accurate shelf life. You cannot leave any amount of OSP open since it can go waste due to environmental changes. 

ENIG Fnish for PCB

ENIG surface finish is much more expensive than OSP. However, manufacturers love ENIG for their PCBs despite its rarity and unaffordable nature. It is the qualities of ENIG surface finish that intrigued the producers when it came to making their PCBs flawless. 

ENIG has a duo of coverings made of gold and nickel. The role of the nickel is to secure the copper layers and to strongly join the components of PCBs together. Gold is for preventing corrosion and protects the nickel from such damage as well. 

There are some major benefits of using ENIG instead of OSP. Let’s find them out below:

• It is better for sustenance during thermal circulation
• It is supportive of the soldering process of PCBs
• ENIG gives an edge for wire binding over other surface finish types
• It is also beneficial to use for high-pitched electronics just similar to OSP

Applications of ENIG:

• ENIG serves best when you need your devices to be more tolerant instead of relying on HASL, as it does not give positive results for this purpose.

The process of ENIG is slightly similar to the OSP. However, we will still learn about it down below:

1. The first step is cleaning which is the same as OSP cleaning
2. The next is to etch the surface just like OSP
3. Pre-dipping is the next step that lays the foundation for using post-dipping substances 
4. Applying the activator is important to make sure there are no complications with the surface finish
5. Post-dipping is for making sure the layers are well in place
6. Applying the nickel for solidifying the connection of components
7. Using the gold for rendering the PCB potential to fight against corrosion

Standard applications for an ENIG surface finish include:

• Complex surface components: ENIG is mainly for complex PCBs, and it is the main difference that sets it apart from OSP. 
  • Wire bonding: The wire bonding needed by ENIG is way too less than OSP, especially for aluminum wiring networks. 
  • High-reliability applications: The PCBs used in the domains of aerospace and medical/healthcare sectors come with ENIG-based surface finish. It is because these domains work on heavy-duty equipment and complex systems that go well with ENIG surface finish. 

Advantages & Disadvantages of ENIG

Advantages

· Flat surfaces

ENIG is reliable for flat and smooth surfaces. It allows fine temperature regulation of PCBs and also protects them from catching fires and undergoing abrasive damage by all means possible. 

· Long-lasting

ENIG is a long-lasting surface finish and makes PCBs reliable in the long run as well. It promises a much higher degree of prevention against corrosion and abrasive damage. Yes, even more than OSP!!! 

It is because ENIG has gold layers that are easy to change and amend as per your needs. Once you have applied ENIG on your PCBs, it will keep solidifying with time naturally without needing any external help at all. For sensitive parts of PCBs, ENIG is suitable. 

· Lead-free

ENIG does not need a lead for its purpose. It means you can use it easily for your RoHs projects. Besides, it will also not create a negative impact on the environment as well. 

· Good for PTH

There can be no other dependable surface finish than ENIG for PTH purposes. It is sufficient to cover the entire PCB at once without making you use it again and again, which can lead to wastage. 

· Maintains solderability during storage

ENIG hates moisture. It means that the PCB parts are less likely to come in contact with moisture that can cause rusting. Due to this, ENIG makes sure that the PCB parts are in optimum condition all the time so that you can focus on other important things meanwhile.

Drawbacks

· Flammable

Now, it’s time to have a look at the dark side of ENIG. If you do not pay close attention to the layouts of your PCBs, ENIG might not like this at all. It can uncover heat-sensitive wires and cause electrical fires. The electrical short circuits can later produce fatal intoxicated emissions that are not healthy to inhale at all. 

· Weaker bond for components

Do you know the gold covering present in ENIG is way too thin? The thin gold layer does not give enough room for the solder to distribute completely among the pads. Now, problems can occur when the PCB parts do not adhere well to the boards due to less amount of solder. 

· Requires professional installation

ENIG is not something that you can manually use without seeking professional assistance. The ENIG application is only possible when you deeply know the correct method of application. 

It only happens when you are a skillful technician. So in case you are not well-familiar with the ENIG application and do it all by yourself. It can lead to wastage, thus increasing the production cost of PCBs at the same time.  

· Requires special materials

You cannot replace ENIG frequently. It is because the nickel and gold layers are expensive and sometimes get totally out of sight in the market. Due to this, ENIG is a questionable surface finish because it uses rare materials and equipment for the application. 

 The Significance Of Your PCB Surface Finish

No PCB can work at its best if its surface is faulty. A fine PCB is one with an appropriate surface finish. The sole purpose of the finish is to protect the PCBs from harsh environmental conditions and temperature changes. Not only this, a good surface finish like ENIG and OSP will prevent corrosion of PCBs and their components as well. However, it is important to go for a suitable surface finish. 

But how do you do that? There are some factors that you can analyze in different options for surface finish. These include:

1. Solderability

Soldering is an inevitable factor to take care of when it comes to producing PCBs. The type of surface finish you are choosing can make or break the soldering as well. If a PCB surface is smooth, it will increase the strong bonds between PCB parts with the boards. Make sure your preferred surface finish provides good wire bonding. These wires include different metals, and not every type of surface finish can fit well with these metals.

2. Processing Time

Some surface finish types take a lot of time to process. For instance, HASL has by far the most extensive process of application among all surface finish types. It means the processing time of the surface finish is important to consider. Some types cannot tolerate prolonged exposures, while others can. 

3. Reliability

The surface finish needs to be reliable under harsh conditions. Otherwise, there is no point in going for expensive surface finish types. Make sure the surface finish type meets the reliability standards on all counts. Don’t waste your investment in buying an unreliable surface finish that cannot withstand complications nor ensures the protection of PCBs. 

Final Words

Now, you know well why the surface finish is an important part of the longevity of PCBs. Also, this post discusses common types that are reliable for surface finish, along with their advantages and disadvantages. You can select the appropriate surface finish based on some factors mentioned in this discussion.

Audio oscillators are widely integrated in generating waveforms in a particular frequency range between 16 Hz and 20,000 Hz. For a low-frequency oscillator, waveforms below 20Hz can only be generated.  Audio oscillators are designed to be used in producing music as tone generators.  

Also, these oscillators allow the measurement of compression and circuit gain at a given frequency. Here, we will explore audio oscillators, its types, and applications.

What is an Audio Oscillator?

An audio oscillator serves as measurement tools and tone generators in music production. An oscillator is designed to convert direct current (DC) to alternating current (AC), which generates an alternating waveform. Furthermore, oscillators help to produce waveforms in a given frequency. A low-frequency oscillator produces waveforms that are less than 20Hz.

There is a quick alternation of the electrical current between two states. This generates a waveform you can amplify and shape with different audio processors. Electronic oscillators are applicable in several industries like measurement, calibration tools, and equipment clocking.

Audio oscillators usually generate sound. Their circuitry quickly changes between two states. This is similar to the way a vibrating string generates a sound. The oscillating electronic circuit produces a waveform which you can amplify and integrate as a sound source.

Types of Oscillators

The Voltage-controlled oscillator or VCO is the most common type of oscillator used in analog synthesizers. A control voltage determines the frequency of the VCO audio oscillator. The VCO oscillator generates a different frequency based on the control voltage you feed it. When you press a key on an analog synthesizer, a certain voltage is sent to the oscillator. This produces a waveform in the pitch.

If you tune the oscillator properly, the pitch will work in line with the key’s note. Furthermore, with synthesizers, you can regulate the control voltage using various types of signals. For example, a Frequency Modulation also known as FM synthesis can be generated by including modulation to a VCO.

VCO audio oscillator comprises three parameters which include volume, frequency, and waveform.  Let’s have an in-depth analysis of how these parameters related to a sound by looking at a sine wave.

A sine wave is the most important aspects of all waveforms. You can alter the shape of waveforms by adding harmonics. Square, sawtooth, sine, and triangle are the primary waveform shapes. Each of these shapes affects the tone of the sound generated. Also, sine waves usually have a smooth sound. On the other hand, sawtooth can be buzzy.

Noise is another waveform oscillators experience.  It usually comes in pink and white variety. While the frequencies of white noise are in equal proportions, pink noise reduces the effect of some of the higher frequencies.

Digital oscillators produce waveforms by integrating DSP or digital signal processing. These waveforms are digitally recreated to look like analog oscillators. There has been some development in modeling technology, however, a good number of synth  enthusiasts usually consider the sound of digital oscillators to be inferior to analog.

Types of Waveforms

Oscillators generate cyclic waveforms. These waveforms are measured in Hz i.e Hertz. There will be more cycles of the oscillator vibrates faster. Oscillators are known to generate different types of shapes. However, the most common shapes on an analog synthesizer include sawtooth, sine, triangle, and square. The waveform line’s curve determines its shape.

Square wave

A square wave includes harmonics that are seen in odd-number multiples of the basic frequency. Also, a square wave looks like a square.

Sawtooth wave

The sawtooth wave looks like a sawtooth blade. Odd and even harmonics are added to a sawtooth wave. Therefore, this causes a clear tone.

Sine wave

The most basic foundation of sound is the sine wave. Sine wave is pure since it has no additional harmonics included in the signal. A sine wave comprises the fundamental frequency.

Triangle wave

A triangle wave has a similar appearance as a sine wave. However, the only difference is that a triangle wave has straight edges that link like a triangle. Odd harmonics are usually added to triangle waves.

History of Audio Oscillator

Audio oscillators were not really suitable for modern applications in the late 1930s. This was because of their cost, complexity, and instability. Therefore, William Hewlett was inspired to design and develop the model 200B variable oscillator which was the first product by the Hewlett Packard company.

After Hewlett attended a seminar at Stanford University,  he was inspired to develop an efficient audio oscillator. In this seminar, Frederick E. Terman, Hewlett’s professor, discussed the integration of negative feedback. This inspired Hewlett to spend time studying this topic for his thesis.

Hewlett’s oscillator was different in that he used an incandescent lamp as the temperature-dependent resistor.  Furthermore, the light bulb functioned as an automatic gain control. This kept the loop gain of the oscillator very close to unity. This is important to achieve the least amount of distortion. The output could easily be controlled without distortion due to this design.

This performance wasn’t only enhanced, but also made cheaper. At that time, the model 200A was sold at 54.40 dollars, which was less expensive than other oscillators in the market which were sold within $200 to $600.

The first method for producing audio signals was the Hewlett oscillator. Before the advent of the Hewlett’s 200B, there was no accurate way to generate low-frequency signals.

What is HP 200A Audio Oscillator?

The HP 200A audio oscillator is a low-distortion audio oscillator specially designed for carrying out test on sound equipment. This oscillator makes use of the light-bulb stabilized negative feedback circuit.  Over the years, HP oscillators were integrated for the production and maintenance of radios, telephones, stereos, and other audio equipment.

The HP200A audio oscillator was developed by Bill during his postgraduate research. As at that time, Bill had an innovative and practical idea of how to use a light bulb to provide solutions to the regulation pf the circuit’s output without any interference. Although there were other oscillators, there were unstable and costly. Bill could simplify the circuit by using the light bulb. Also, he was able to enhance the performance of the oscillator and as well minimize the price.

Bill and Dave designed the HP 200A audio oscillator, their first product. The HP 200A oscillator was dubbed in such a way that it looked like it had been existing for a while. This oscillator was priced at 54.40 dollar. The oscillator was less expensive than the competitive equipment at the market as at that point in time.

According to Dave, the HP audio oscillator served as the foundation on which the HP company gained popularity and became one of the world’s largest producers of electronic instruments.

The Wien Bridge Oscillator

The Wien Bridge oscillator was designed for producing audio frequencies. This oscillator has more advantages. It is better than the phase shift oscillator since the produced frequency may be within the range of 1:10.

Wein Bridge oscillator produces a wide range of frequencies. It produces sine waves and is based on a bridge circuit created by Max Wien for measuring impedance. There are two capacitors and four resistors in this bridge. In most cases, the Wien Bridge oscillator helps to identify unknown values of components.

Most times, this oscillator is usually integrated in the audios.  Also, this oscillator is mainly used for testing audio. It can generate clock signals used for testing filter circuits. Another application of this oscillator is in testing of amplifiers. Wien Bridge oscillator can help to carry out distortion testing of power amplifiers.

In this oscillator, when there are lower to higher frequencies, at a certain frequency, the capacitor reactance and the resistance are equal to each other. Therefore, there has to be a maximum output voltage.

What is the 555 Audio Oscillator?

The 555 audio oscillator is used for producing stable square wave output waveforms of various duty cycles that ranges from 50% to 100 % or a fixed frequency of about 500kHz. In order to produce a 555 audio oscillator circuit, you can link the 555 timer IC in astable mode.  

This oscillator serves several purposes; therefore, it is used in many applications. You can use the 555 audio oscillators in various waveform generator circuits and applications where low output current is required. Furthermore, 555 oscillator is ideal for use in producing accurate pulse, square, and sine wave forms. It is a type of relaxation oscillator.

This oscillator can be easily built to flash a few LED’s. However, there is one simple way to develop a science project by integrating an astable 555 oscillator is Electronic Metronome. Electronic Metronome is a device that marks time in pieces of music by generating a recurring beat.

Conclusion

Oscillators are the best and easiest way to produce a particular frequency signal. The oscillation’s frequency can vary. However, audio oscillators work within a frequency range. Audio oscillators are widely integrated in several applications. You will find them in TV, radios, and other devices.

Audio oscillators usually generate sound. Their circuitry quickly changes between two states. This is similar to the way a vibrating string generates a sound.

Change and development are necessary in life. Even in the electronics industry, there has been constant evolvement, innovation, and development. This industry is continually experiencing growth and development. While technology and device circuitry density are becoming more complex, electronics manufacturing depends more on out-sourcing.

Today it is more complex to minimize ESD losses. Users need a way to evaluate and make comparisons between competing brands and ESD protection strategies. The ESD means electrostatic discharge . This standard is important in the electronics assembly industry. It is crucial for electronics manufacturing, assembly, repair, or any other aspects that involve electronic circuits and components to adhere to the ESD standard.

What is the ESD Standard?

The ESD Standard was set up in order to ensure organization within concerned industries could protect their electronic products and components form ESD. ESD means electrostatic discharge. It is a great issue which could cause damage to an electronic component. If proper care isn’t taken, ESD can destroy an electronic component completely.

Therefore, the ESD standard helps to ensure ESD doesn’t build up in the first place. For instance, in Germany and some European countries, the standard DIN EN 61340-5-1 is important. The ESD standard guarantees consistency of ESDS items and as well as the consistency of ESD control products. This standard is a means of making comparison among ESD control products.

Furthermore, this standard minimizes conflicts that arise between ESD control products suppliers and users. It develops, integrates, audits, and approves ESD control programs. The U.S makes the integration of this standard voluntary.  ESD regulations should be prioritized in cleanrooms.

What causes electrostatic discharge in electronics products?

Electrostatic discharge occurs when there is an abrupt electricity flow between two objects that are electrically charged. There are several causes of ESD. ESD can result from contact of the two objects by dielectric breakdown. ESD causes damage in electronic circuitry. Electricity flow can cause a hole to burn in an integrated circuit. The area which surrounds the hole would as well possess discernible heat damage.

Even if this occurrence didn’t result in a hole, an ESD will disrupt the operation of the equipment. However, internal components will wear down over time due to the frequent occurrences. Lack of ESD protection will cause electronic components to easily break down. The rate at which electronic components break down will be faster. Therefore, this will interfere with operations and as such, minimize quality and enhance costs.

What is ANSI ESD S20 20 Standard?

Electrostatic discharge poses costly and dangerous risks to electronic products. Not only does it pose a great damage to electronics, it also causes damage in pharmaceutical, medical, and other important industries. To meet the increasing demand for sound ESD control programs, the ESD.EOS Association Inc set up a third-party certification program. The ANSI ESD S20.20. is a standard set up by EOS/ESD Association, Inc.

This standard was established through ISO9000 Certification Bodies. The ANSI ESD S20.20.offers technical and administrative provisions designed for some particular requirements or applications. Also, this standard offers a great basis for the control process and integration of the standard.

Furthermore, the ANSI/ESD S20.20 standard makes it possible to guide all aspects of building the ESD control programme. Also, it is ideal to be supported by the management for the area impacted by the ESD control process.

Who Develops the ESD Standards?

The development and integration of standards is usually a cooperative effort by individuals and organizations impacted by these standards. There are several major ESD standards development organizations.

Military standards

The U.S military is in charge of the developing certain specifications and standards that involve ESD control. However, the military agencies in the U.S are now depending on commercially developed standards. For instance, the ESD Association converted MIL-STD 1686 into a commercial standard known as the ANSI ESD S20.20.

ESD Association

For the past years, the ESD Association has taken center stage at the development of ESD standards. The ESD Association sees to the development of test methods and ESD standards. Also, the ESD Association  represents the United States on other programs.

Furthermore, there are several technical reports and standard documents in the ESD Association. These standards oversee the areas of test methodology for ESD control  products evaluation and electrostatic sensitivity. Furthermore, the ESD Association published some advisories which contain some pices of information. The advisory documents may be altered in the future.

What is the IEC 61000 4 2?

The IEC 61000-4-2 standard defines ESD protection, by integrating two  testing methodologies. The contact discharge methodology discharges an ESD pulse from the ESD test gun that is in contact with the device under test. This methodology is highly preferred. The second methodology which the IEC 61000 4 2 makes room for is an air discharge. This methodology is ideal for scenarios in which it is impossible to maintain contact discharge testing.

The air discharge test involves bringing the ESD test gun close to the device under test until there is a discharge. These standards must be defined in such a way that each level is equivalent. Therefore, a Level 4 contact discharge of 8 kV is the same as an air discharge of 15 kV.

The IEC 61000 4 2 is an ESD immunity compliance standard for electronics that need to get the UL, CE Mark, and other certification. Electrostatic discharge ESD occurs everywhere. It occurs between high density electronic components in electronics products like television and mobile phones. It is impossible to predict ESD. Therefore, it is important to take some measures that prevent malfunction or damage of a device when ESD occurs.

The IEC 6100 4 2 is the most popular standard for evaluating robustness and approving commercial electronics. This standard is an effective EMC test standard needed to attain a CE marking. With IEC 6100 4 2, electronic producers can sell their products in Europe.

What is the Importance of ESD Protection in Electronic Products?

Like it was earlier explained, ESD can cause significant damage to electronic equipment and as such, this could lead to a catastrophic failure in the field. In the electronics manufacturing industry, minor mistakes or errors can be detrimental to the functionality of electronic components and devices. ESD damage is one of the most common causes of product losses.

Electrostatic discharge (ESD) occurs when built-up charge releases between objects, thereby, resulting in the flow of electricity between these objects. ESD of charged objects caused by humans statically charged objects can cause damage to different semiconductor parts which include CMOS IC chips, MOSFETs, and diodes.

In most cases, 60 to 90 percent of damages caused by ESD doesn’t cause complete failure. However, this damage can be difficult to detect. Therefore, it is of utmost importance to minimize and regulate ESD during circuit board assembly.

ESD protection is crucial in any electronic products as it helps to prevent any damage. Any electronic component or product is vulnerable to damage due to exposure to ESD. Also, ESD protection is crucial in preventing the formation of static charge in electronic products. The main purpose of creating the ESD standards is to minimize the risk of damage to devices that are sensitive to ESD.

Furthermore, this protection is ideal for minimizing failure in electronic device and as well as enhancing the performance and reliability of delicate electronic components or products. Adhering to the ESD standards is crucial for industries that produce delicate electronic equipment. Therefore, the ESD standard is great measure to prevent and also address all ESD related problems.

Electronic companies need to adhere to all the procedures of ESD standards. Also, these standards should be integrated in the appropriate way.

How to Control ESD

There are some preventive and precautionary measures that can minimize ESD for electronic assembly. These measures include:

• Make use of anti-static equipment and tools to prevent electrical charge conduction. Also, do not work on electronic device when there is electrical storm as this can increase the risk of ESD.
• Circuit board rework or component repair should be carried out in an ESD safe environment.
• Use ESD-safe tables or workstation to enable the dispersion of static electricity. Electrically conductive carbon fibers are used in manufacturing these mats. Therefore, ESD becomes inactive on the mat.
• Wear a grounded wrist strap to minimize any risk of ESD incident. Ensure you wear this wrist strap correctly as it will protect any charge generated by the body.
• ESD air ionizers can be used by engineers as they get rid of static charge from the air.
• Employees may need to put on anti-static clothing to shield sensitive components and ESD shock.
• Avoid using jewelry and some static accessories in the workstation.

Conclusion

The ESD standard for electronic assembly has helped in preventing some damages to electronic products. There are a wide range of standards set up to ensure safety and protection while using electronic products. Some of these standards are the IES 6100 4 2, ansi ESD s20 20 and the ISO 10605. Electronic manufacturers and assemblers should endeavor to adhere to these standards to ensure safety and reliability of electronic products.

You must be wondering what the colorful stripes found on the resistor really means. Or you really wish to know what functions the 4.7K resistors serve in electronics. Here we are to explain the ins and the outs of the 4k7 resistors. These include their applications and basic properties.

What Does a 4.7 K Resistor?

The 4.7 k resistor can be described as any electronic component that has a resistance of 4700 ohms or 4.7 kilo-ohms. This “k” is seen in 4k7 means kilo which indicates 1000. A resistor’s resistance can be measured in ohms which is an electrical resistance unit. Resistors are useful in limiting the electric current flow in circuits and are usually utilized in different electronic devices.

You can easily recognize the 4.7k resistor due to its unique pattern of violet, yellow, red, and violet color bands. Furthermore, the band versions 5 and 6 comes with a pattern of violet, yellow, brown, black, followed by its temperature coefficient band and tolerance band on the band version 6.

There is one difficulty with the resistance 4.7 k ohm resistor. This is happening because you can easily confuse it with the 470 ohm resistor. Therefore take note of this and verify mak8ng use of the multimeter or color codes where necessary.

Color Bands of the 4.7 k Ohm Resistor

Every band found on 4.7 kilo ohm resistors comes with a unique purpose. Regardless of the number of bands present in them, all the color-coded resistors have a minimum of two digit bands. One is a multiplier band, while the other is tolerance. This structure forms the four-band resistor color codes; the five as well as six band resistors usually add to the basic structure.

In four band resistors, the initial three digits will give the nominal value of the resistor. While the fourth band will give the resistor’s tolerance. Although the resistor comes with the nominal value of 4.7k ohm, its actual resistance would vary a little bit below or above its nominal value. This tolerance reveals to us the expected range. Resistors of higher quality features improved tolerance over the ones with lower quality.

In the five band resistors, the initial four bands will reveal the resistor’s nominal value. Take note that the extra band of the resistor helps in adding a specific digit to its nominal value. Consider this as an additional digit which has been added into the front, with other bands that retains similar functions as the four band resistor. Also, the final band, which is the 5^th band, identifies tolerance.

The six band resistor helps in adding a new color band at the resistor’s end, which reveals the coefficient of the temperature. This indicates the resistor’s sensitivity to changes in temperature. All resistors come with its own tolerance value. This means the value may not be 4.7 ohms exactly. Resistors with higher quality feature tighter tolerances.

4 Band Vs. 5 Band 4.7 k Ohm Resistor

According to our explanation, four band resistors feature two bands for the value. The first value is the tolerance while the second value is for the multiplier. Five band resistors feature three different bands for the value in which one is for the tolerance and one is for the multiplier.

The process of analyzing the five band resistor is similar to the four band resistor. Therefore, you have to look for any gap between the fourth band and the fifth bands. However, the last band in the four band resistors reveals the tolerance. You can then use the first four bands to get the resistance value.

There should be an order of violet (7), brown (x10), yellow (4), gold or silver (+-5% or 10%).

What is Resistance Tolerance of 4.7K Resistor?

The tolerance of a resistor indicates the resistance value of a resistor can feature. Therefore, the tolerance of a resistance 4.7 K ohm resistor depends on the specific series and the manufacturer of the resistor. 4.7 K ohm resistors have common tolerances which are 10%, 5%, and 1%.

• For a 4.7K resistor with a 10% tolerance, the actual resistance ranges from 4.23k ohms to 5.17k ohms
• For a 4.7K resistor with a 5% tolerance, the actual resistance ranges from 4.46k ohms to 4.935K ohms
• For a 4.7K resistor with 1% tolerance, the actual resistance ranges from 4.653 ohms to 4.747K ohms

Common Applications of 4.7K Ohm Resistors

The 4.7K Ohm resistor is widely used in different applications. This resistor serves a lot of purpose.

Voltage dividers

4.7K ohm resistors is widely integrated in voltage dividers. These resistors produce a particular level of voltage. Also, there are two resistors on series in a voltage divider and the output voltage is very proportional to the two resistor values. Due to the tolerance level and availability of 4.7 Kilo ohm resistors, they are ideal for use in voltage dividers.

Current limiting

Also, you can use 4.7K ohm resistors to limit current. For instance, these resistors can help to restrict the flow of current via an LED. They can as well prevent the occurrence of overvoltage in a microcontroller input.

Pull-up or pull-down resistors

These resistors also serve as pull-down or pull-up resistors in digital circuits in order to ensure the maintenance of the voltage level of a signal. This is possible even in cases where you can’t actively drive the signal. Therefore, 4.7K ohm resistors can prevent floating in input signals which is caused by an unexpected behavior.

Oscillator circuits

Another use case of a 4.7K ohm resistor is in oscillator circuits. This resistor helps to set the frequency of an oscillator. Also, you can use this resistor with other components like transistors and capacitors to produce a particular frequency signal.

Analogue Signal conditioning

4.7k ohm resistors serve some purposes in analogue circuits. These resistors are suitable for signal conditioning circuits as they help to adjust offset or gain of an input signal.

Conclusion

Today, various consumer electronic devices require tiny packages with various pins. Because of this feature, engineers invented surface-mount Dual-in-line packages and Pin Grid Arrays that give track lower density. However, manufacturers of PCBs face many challenges. Pin bridging is among them. BGA, however, allows us to overcome this problem as the BGA solder balls provide the appropriate soldering needed for placing the package. Therefore, they place solder balls close to each other. This provides strength to the interconnects and minimizes the PCB footprint. BGA components create high-density interconnections which use the surface of a PCB effectively.

· Reliable Construction

The pins of the PGA package have a fragile and thin structure. Thus, resulting in the bending and damaging of these pins. Whereas, this is not the case with the package of BGA. In the BGA package, the solder balls are incorporated over the solder pads, which enables the network to be more reliable.

· Excellent Performance At High Speeds

In the BGA package, all the soldering balls are placed close to one another, which creates a close connection between components, minimizes signal distortion, and strengthens the interconnections during high-speed tasks. This shows that the network provides greater electrical conduction over high speed.

· Less Component Damage

Unlike PGA, the heating process melts BGA solder balls which enables them to connect with the Print circuit board. This, however, aids in minimizing the risk of component breakdown or damage.

· Reduce Overheating

The packages of BGA contain various thermal networks that dissipate the heat from the ICs. Thus, this effectively minimizes the risk of overheating.

Cons Of CTBGA (Thin Chip Array Ball Grid Array) 

BGA also comes with drawbacks, like all other electronic devices. However, the drawbacks include:

· Difficult To Inspect

BGA is basically a tiny material piece that allows the manufacturer to place the die of an IC over it. Because of the tiny size of BGAs, the inspection of soldering joints becomes difficult through visual inspection. However, X-ray machines and advanced microscopes may help in solving this problem.

· Prone To Stress

Circuit boards give flexural stress, which further affects BGA. Though, this stress causes reliability issues.

· Excessively Expensive

The soldering process of BGA packages requires highly expensive equipment. This, however, makes the BGA packages more expensive. Furthermore, manual soldering is used in packaging but in extremely lesser numbers.

All the above-mentioned advantages and features add up in the usage and application of BGAs. Thus, increasing the demand for Ball Grid Array packages. Though BGA devices use advanced types of technologies, they are skeptical of failures. Therefore, inspection of every joint on the board minimizes the process of rework. If you are thinking of incorporating BGA into your device. Then choose trustworthy, reliable, and industry-leading manufacturers. Various companies offer a vast range of customizable BGA packages.
