PCB Manufacturing and Assembly China: Baking PCB Components

PCB Manufacturing and Assembly China

In recent years, the need for electronic components has seen an increase in demand. And as technology continues to evolve and become more complex with each passing day there’s no sign of this trend slowing down any time soon so it is important that we find ways like PCB Manufacturing and Assembly China which specializes mainly in baking up circuit boards made out primarily from p-type semiconductors such producing logic gates using NPN transistors or PMOS Mosfets – all depending upon what device you’re looking at building!

PCB baking is the pre-treatment to dry printed circuit boards and moisture-sensitive components before they are assembling so that no moisture remains inside or on their surface. Assembling of these components takes place away from soldering errors such as IC popping using this technique; which could happen if part of it was still wet when are installing onto a device’s board during assembly time.

How to Bake Bare PCB?

Many people have asked me how to bake a PCB. The answer is surprisingly simple. First things first: make sure your circuit board has all its components installed on it (these can include resistors or light pipes). Then take out some flour paste from the tube-because this makes them stick better than any other type of glue agent; arrange ten 8×8 mm grid squares over each side as shown below for small PCBs like what we are going use later today…or put some down where ever looks good–just try not too overlapping when arranging so they look even across+/-2cm).

You might be wondering why should you bake your printed circuit boards? Well, there are a few reasons. First of all, it will get rid of any excess moisture inside the board itself which could lead to corrosion or other unwanted effects on its lifespan. Second thing is that by doing so we’re making sure they don’t warp when folded over during assembly. This is imperative in electronics where compact size often comes at the expense of ruggedness! The third reason (and maybe most importantly) involves safety. Pre-heating these components reduces their chance of catching fire from static electricity build-up while being handled because high temperatures cause some plastics and nylon.

Baking temperature: 120±5℃

If the circuit boards are storing for 5 to 60 days, they need 1 hour of baking. If you have your PCBs (Printed Circuit Boards) for more than 6 months and want to store them indefinitely in good condition. Then we recommend that you should bake at least 2 hours before using them again. The longer a project has been sitting around without being used, the less likely there will be enough heat flux from our solder masks or components on these circuits due to reducing conductivity which could lead not only an increased risk.

How to Bake Electronic Components?

Baking is a necessary step for many surface-mounted devices (SMD) such as ICs and BGAs. Moisture-sensitive components can store at room temperature with relative humidity smaller than 50%. The process of baking depends on how much moisture it’s baking in, the type of component itself, where they are mounted onto equipment along assembly lines.

Baking’s temperatures can vary depending on what device you’re working with. Typically anything under 0 degrees Celsius should remain intact if not heated above this level during its duration. While higher temps may cause warping or melting depending upon each individual situation. To bake a component at 90°C and 40%, you need to bring its humidity close to 5%. This is so that moisture can leave the part from within as well.

How Can I Determine Whether or Not the Components Are Baking?

The packaging bag for moisture-sensitive components has a humidity indicator card and the control period printed on it. If you find that your dish is beyond its usable life or when checking the meter starts to turn pink, then simply put them in a 180° oven preheated at 350 degrees Fahrenheit (176 Celsius) until they reach room temperature again. 2 minutes should be enough if outside edges are cool while cooking interior hot. Though most often we only need about 10 minutes due time differences around here!

For the ICs that are beyond their control period or indicator cards, here is what you should do:

BGA IC trays will bake at 125 ± 5℃ for 32 hours; reel-type chips need to bake up in a hot environment and it’s best if they can cook at 60°C (140 ° F). Other types of integrated circuits such as QFP/TQFP packages can withstand higher temperatures. However, they still require 24-hour exposure time before programming begins. So make sure yours have reached this stage first! If these requirements aren’t met then consult with your customer service team about whether there could possibly be another problem leading.

What Happens After the PCBs And Components are Baking?

It’s important to get the baking process started right away, and then it only takes a couple of minutes. Once everything has cooled down enough for handling, we’ll be able to take out all our circuit boards so they can go through their final assembly steps!

Turnkey Manufacturing Capabilities Ensure Fast PCB Prototyping Service

Turnkey Manufacturing Capabilities

Turnkey manufacturing capabilities require a popular Greek proverb that Socrates often quotes in his talks and writings. The proverb demands the person or the user to know the problem. By this, it means that for a person who doesn’t know his problem he eventually will fail to solve or come out with a proper solution.

Therefore, for an engineer, working on fast prototyping services, or any other task, knowing or understanding the issues he faces is of utmost importance. This is one of the phrases that should be ingrained in the memory of an engineer. This would eventually help the person to find the right solution for a particular problem surfacing. It is because without first understanding the right problem, it becomes impossible to reach the ultimate solution. Hence, one can only devise the perfect solution, one fails to produce the desired solution or method. Read more here

Guidance For Manufacturers Regarding PCB Prototyping

The axiom about knowing the issue is a guiding principle for many engineers. The statement, however, is also true and helpful for the contract manufacturers in producing the PCB prototyping by turnkey manufacturing capabilities as well. It is because, in the manufacturing process for contract manufacturers, quality, high volume production, large capacity as well as the cost of production are the primary factors of concern. For this reason, hence a manufacturer must consider several options when it comes to prototyping. In these considerations, a few of them are considering which board fabrication, assembly for PCB, acquisition, and component sourcing do you look for.

It also includes considering if a manufacturer requires any assistance regarding design for manufacturing (DFM). Last but not least is that how effective and beneficial becomes the product is when a manufacturer uses fast PCB prototyping services. Therefore, answering these question and considerations become the prime objective of the user. These points will also help you to choose the right contract manufacturer for you as well. Moreover, these points will also help commence the perfect PCB prototyping designing and development process. Here, Turnkey manufacturing appears to be a helpful method. Therefore, let us discuss the benefits of using the method in fast PCB prototyping services.

What Is the Importance of Fast PCB Prototyping Service?

In turnkey manufacturing capabilities for fast PCB prototyping services, the primary concern for any owner and manufacturer in product designing and its development is the creation as well as the verification of the prototype. The development and creation of the prototype eventually entails and clarifies to you whether your product is capable enough to be even produced in time and also affects the timeline of overall production. for this reason, hence, the production and manufacturing of PCB are equally important.

Therefore, it becomes a prime concern of every business to select the right CM for their project. It equally is the most crucial step as well. The reason behind this is that choosing the right CM involves finding out what types of PCB manufacturing services you are getting. Therefore, to determine if the fast PCB prototyping services are best for your project, there are some questions that you must ask yourself.

  • Are multi-iterations necessary to finalize your project?
  • Is your project time-sensitive?
  • Is a single set of design files being enough?
  • Also, is your design team being sufficient to design your product instead of just tracking?
  • How helpful is receiving design support from Design for manufacturing engineers?
  • Is the deal with a single contract manufacturer enough?

If your answer to all of the questions above is NO, then you do not need turnkey manufacturing capabilities in fast PCB prototyping services. On the contrary, if you are YES about these questions, you will get the most benefit out of it.

Benefits Of Turnkey Manufacturing Capabilities in Fast PCB Prototyping Services

Irrespective of the fact that the turnkey manufacturing capabilities are the fastest PCB prototyping services available in the electronic industry. However, there are many other board fabrication and PCB assembly units and companies in the market which are very fast and possess fast turnaround services. It is because of their particular role in manufacturing these products.

turnkey manufacturing capabilities

Those services, nevertheless, are limited to just board fabrication and PCB assembly. But turnkey manufacturing carries other options such as fabrication, assembly as well as component acquisition as well. Therefore, if the CM combines all the PCB manufacturing steps, he will get the advantage of inherent process management. He will be able to maximize the benefits as well. Those benefits will include faster turnaround time in manufacturing and the best design quality products.

A few of the advantages that we can get from using the turnkey manufacturing capabilities in fast PCB prototyping service are:

A single company for all the necessary processes

Using multiple firms and platforms to get your work done makes things irregular for the owners. However, if one gets to utilize the advantage of getting the work done under one roof, things start to get streamlined and the manufacturing process goes so smooth from every perspective. For this purpose, the lender doesn’t have to schedule different tasks and also coordinate with multiple points of contact.

Only Single Set of Design File Is Enough

Unlike the contrary methods, in turnkey manufacturing capabilities, the person only needs to have one set of design files in CAD format. This is exactly the opposite of the traditional method where we need to provide multiple data files in separate formats. This is for the different processes such as Fabrication, Assembly as well as Component Acquisition.

No Need to Acquire Component

In turnkey manufacturing, there is no need to track, order and deliver every single component and to acquire it separately. However, in traditional methods, all these things are necessary. But these steps require devoting man-hours and also dedicating personal to track, order, and deliver components. In all these processes, what we need is a lot of significant time and cost as well.

turnkey manufacturing capabilities

Achieving Better Quality Control

The quality of the product, as well as the process, becomes refined when it comes under the handling of single management in a single firm. The oversight of the process and quality control becomes better in turnkey manufacturing capabilities.

Introduction of Circuit Board Assemblies and Different Ways to Go About it 

A Brief Introduction to Printed Circuit Board Assemblies

We all know the importance of electronic appliances in our daily lives. They are in various forms. But surely, a few of us know about printed circuit board assemblies and their role in the efficient performance of electrical equipment. Printed circuit boards are electronic boards that connect components of an electronic device. They comprise a non-conductive material, contain lines, pads, and other features etched on copper sheets. All these components connect the electronic assembly inside a device. Some electronic components such as resistors and capacitors need soldering for fixing on the printed circuit boards.

Today, printed circuit boards are also common in electronic devices required in various industrial appliances needing powering. The high-powering industrial equipment needs durable and exceptionally high-powered printed circuit boards to handle various applications.  

circuit board assemblies

Different Ways to Create Printed Circuit Board Assemblies 

The main processes for various assembly processes are:

Through-hole mount process

This process involves the assembler soldering component into holes bored into a bare circuit board. This technology is the perfect solution to create a stronger connection than surface mount technology. Applications requiring high-reliability demand such assemblies. This is because the leads move through the board instead of attaching with solder. This type of technology mostly benefits testing and prototyping applications needing manual adjustments of components.

Surface mounting process

This procedure mounts electric components directly to the circuit board’s surface using solder. Surface mount boards use smaller parts called vias to connect different layers of circuit boards. Moreover, today, it is the most popular technology and serves as an alternative to conventional assembly procedures. With surface mounting, the assembler attaches components to both sides of the board conveniently. Surface-mounted components are usually smaller in size, and therefore, it becomes easy to fit more marts on a single board. Moreover, this technology lowers down the costs and makes electronic devices get smaller and smaller with time.

Electro-mechanical process

It is also called box-build assembly. This process involves elements like wire harnesses, custom metalwork, looms, molded plastics, and cable assembly to assemble circuit boards.

Engineers seeking prototype printed circuit board assemblies should look to partner with a company that produces the result you want.

Different Types of Printed Circuit Board Assemblies

Manufacturers classify printed circuit boards based on their assemblies according to consumer needs, design specifications, and manufacturing processes. In addition, varying application requirements in defense, medical, space, and automotive industries need intricate circuit boards to enhance mechanical and electrical stability. The different types of circuit boards assembled for various applications are:

  • Single-sided printed circuit board
  • Double-sided printed circuit board
  • Multilayer printed circuit board
  • Rigid printed circuit board
  • Flex printed circuit board
  • Rigid-flex printed circuit board

Single-sided printed circuit board

It is the most common type of circuit board containing a single conductive copper layer placed above the substrate. The soldered electrical components on one side of the board are visible along with the entire etched circuit on the board. The paths on these boards do not intersect or overlap due to a single conducting layer on the board.

These circuit boards suit low-density design applications needed in low-cost electrical/electronic instruments such as calculators, and timing circuits, etc.

Double-sided printed circuit boards

In these types of circuit boards, a thin layer of conducting material like copper exists at the upper and bottom of the board. In addition, the drilled holes in the circuit board connect metal parts from one side to the other. These circuit boards connect the parts on either side using through-hole technology or surface mount technology. Double-sided circuit board assemblies serve various applications, including test equipment, cell phones, power monitoring, amplifiers, UPS system, and more. 

Multi-layer printed circuit boards

These boards feature at least three conductive layers of copper. The boards’ design looks like a sandwich style. The double-sided conductive layers separate through an equal number of insulating material sheets. The assembly procedure involves bonding and lamination under high pressures and temperatures. As a result, there are no air gaps which leads to the stable working of circuit boards. They are common in laptops, computers, laptops, tablets, medical equipment, mobile phones, and GPS trackers, etc.

Rigid printed circuit boards

It is not possible to twist or fold multi-layer printed circuit boards. Their rigid substrate provides them rigidity and strength. These boards comprise multiple layers including a copper layer, a substrate layer, a silkscreen layer, and a solder mask layer. All the layers adhere together. Once made, it is impossible to change these boards. They are compact, cost-effective, and lightweight. However, once made, they cannot be modified or changed.

Flex printed circuit boards

They carry many printed circuits and components arranged on a flexible substrate. Also, commonly made from polyamide, these printed circuit boards use the same components as rigid printed circuit boards. The difference is it is possible to flex these boards to the desired form throughout the application. They save space and eliminate connectors.  

Rigid-Flex printed circuit boards 

They combine elements from both flexible and rigid circuit boards. IT is easy to fold and flex them during the manufacturing process. Rigid-Flex circuit boards are complicated because of their design in 3D. Their lightweight nature makes them an excellent part of an extensive range of applications in the medical, aerospace, and consumer electronics fields.

All the above-mentioned printed circuit boards efficiently serve in consumer PCB assembly products.

The micro-sectioning analysis relies on two-dimensional imaging. This takes place by making cross-sections within the board. It is usually helpful in identifying different sections like opens, shorts, Connection reflow, Faulty mechanisms, and Thermo-mechanical complications.

Moreover, the major reason for performing Micro-sectioning functional Testing analysis is to remove all the faulty parts in the circuit board. Usually, these faulty parts are unable to attribute to the functioning of the circuit board. However, micro-section is damaging to the board in its own right, it still is a reliable method for eliminating bugs.

It allows the experts to investigate the sections regarding their plate thickness, faulty soldering points, erraticism in layers volume and thickness. Hence, it is a consistent method for testing circuit boards preferred by many manufacturers.

Circuit Board Assembly Contamination Functional Testing Service

A circuit board is capable of being contaminated very often during manufacturing. This contamination can result in corrosion, degradation, and metallization. Therefore, the contamination test allows the examiner to detect if there is any corruption in the circuit board.

Most commonly found contaminations include fluid residue, responsive products, human derivatives, and improper handling. The occurrence of tampering in circuit boards is not unusual. Rather it is happening on a frequent basis so it is important to test the boards for the presence of such faults.

The contamination test design majorly focuses on finding ionic bulks and similar stuff. The test allows the circuit board falls into the standards set on an industrial basis. This assures the quality of the board and allows the user to employ it in their everyday manufacturing without worry. The variables may change during the testing but the motive remains the same.

An integrated circuit is much more than just a transfer of coding and decoding. They need to work together in a unified amalgamated form to achieve a common motive. An introduction of Integrated Circuit Programming can elaborate its working and applications.

Introduction to Integrated Circuits

An integrated circuit comprises controllers, transistors, capacitors, and other components required in a circuit. The integration of such components builds up the small chip at the end that allows other stuff to operate. There are different types of circuits demanded by different manufacturers depending on their needs and specifications.

https://www.6pcba.com is an online facility that provides all sorts of integrated circuit chips that facilitate the working of devices. Integrated circuits are quite small in size that helps other devices to perform their functionality actively. The accurate integration of smaller components like diodes ad resistors can produce a beneficial output.

The secondary idea behind any technology is to achieve compactness without compromising its features. In early technologies, vacuum tubing played a major part in making an integrated chip. The size of the vacuum tubing acted as a bug hindrance which is why transistors came into existence. They majorly cut the integrated circuit chip size to half.

It had drawbacks of its own. The more the number of functions added to the integrated circuit chip, the number of transistors increased accordingly. This significantly increased the complexness of the circuit. Therefore, the need arose for much more compact circuits that were smaller in size and inexpensive at the same time.

The need for Integrated Circuit programming

Judging by the increase in the number of problems due to the big size of circuits, the researchers had to come up with a chip that was compact in nature yet fully functional. The idea of using Integrated Circuit programming gave a push to the idea of compactness. It added to the allure of making circuits smaller than earlier versions with the fabrication of using integrated circuits.

Moreover, the basic and core change was to use a silicon chip y mount all the other components. The interconnection of all the components helped achieve the desired results. Integrated circuits made on semiconductors proved much successful. The placement of electronic circuits using the etching technique that incorporated the photolithography process helped a lot.

This unique technology paved a path for future circuit constructions like microelectronics and Nano-electronics. Coming to the present has allowed further research and builds a solid ground for improvements. The rapid adaption of Integrated Circuit programming in integrated circuits is feasible in several applications. Furthermore, there are some major advantages of using electronic gadgets.

Types of Integrated Circuits

There are multiple types of Integrated Circuits. They are further categorized on the basis of requirements and specifications. The different types include digital integrated circuits, analog integrated circuits, and mixed integrated circuits.

A digital integrated circuit works only at specific levels rather than the entire layout of the gadget. Its components include flip-flops, multiplexers, and similar electric basics in a circuit. They operate on digital input. This means that it can do only two actions either it remains on or off. The rest of the work falls on other integrated circuits. This is why they are frequently part of an integrated system as they cannot operate separately.

An analog integrated circuit keeps on working constantly. They further categorize into Radio Frequency Integrated Circuits and Linear Integrated circuits. Due to the vast range in between the signaling of volts and currents, the results are undeviating. It allows the manufacturers to make less use of transistors when compared with digital integrated circuits.

A mixed integrated circuit is a combination of digital and analog integrated circuits that mount on one small chip. Since it is a mixture of circuits it can perform dual functions. This is proof of advanced technology and how far the technology has come. These advanced developments using integration techniques can help achieve multiple goals.

Some more examples of integrated circuits are logic circuits, comparators, switching transistor-inspired designs, amplification devices, timed integrated circuits, and the list goes on and on. The following are some of its applications and advantages. They can help as a guiding light for the most suitable applications that can be enlisted in the successful use of integrated circuits.

Application of Integrated Circuit

We can count numerous applications of integrated circuits even in our daily lives. It has different variations that include watches, radars, and computers. You can even locate them in your households in food factory gadgets, television, audios, and radios. Some more advanced applications include decoders, encoders, regulators, microcontrollers, sensory devices, and many more.

Integrated circuits have become a constant part of our lives. Their compact size allows miniaturization of devices and can reduce the weight considerably. It even affects the cost since the amount of material involved is minimal.  They are highly reliable and can promote unsoldered connections that are much less prone to failure. It even requires a very little amount of power to operate optimally. Moreover, the chip is easily replaceable if it starts to work abnormally.

Integrated Circuit programming


Integrated circuits are very beneficial hence they provide infinite options in different applications. They are successfully replacing the bigger underlying workings with compact integrated chips. Further improvements can extend its usage in even wider varieties of applications. This is beneficial and advantageous at many levels for technological reasons.

PCB Assembly Testing Service: 4 Important Techniques

PCB Assembly Testing

Before embarking on the process of evaluating what is PCB Assembly testing service, it is vital to understand what assembling testing is. Another pertinent question is why is assembly testing so important?

PCB stands for the print circuit board. It is the printed circuit board that offers mechanical support as well as connects the electrical components electronically. The base of the PCB comprises a non-conductive substrate laminated with copper sheets. A variety of traces, conductive pathways, and tracks are etched on the sheet. PCB Assembly is the process of connecting these components.

For a layman, a PCB assembly simply refers to connecting and attaching the mechanically and electrical components such that electricity flows smoothly. The disruption to the flow of electricity leads to malfunctioning and interruption in the otherwise smoothly functioning electronic devices.

Why is PCB Assembly Testing Necessary?

The PCB Assembly ensures the successful operation of electronic devices. Thus, once a PCB has been assembled, it is necessary to test it. This is just like after learning any new thing you have to undertake an exam to prove your competence. Similarly, assembly testing is to prove the feasibility of a PCB Assembly.

In the long run PCB assembly testing has a plethora of benefits.

PCB assembly testing ensures that faulty product is eliminated at an early stage. The assembly testing identifies the bugs during the design stage. This gives a chance to fix the electronic item before full-scale manufacture. The only way out is to eliminate the product in case it cannot be fixed. In this manner, PCB assembly testing significantly reduces cost. It also allows conserving time.

The PCB assembly testing ensures that the final product is free from all bugs and errors. It also leads to establishing a good repute of electronic goods in the market. When the final product is free from faults, there is barely any need to handle customer complaints and defective products. Moreover, due to the high functioning products the company establishes a stronghold in the market due to high customer satisfaction.

Short-circuiting and other hazards are far from uncommon with electronic items. PCB assembly testing inadvertently reduces the risk of such hazards. Thus, PCB assembly testing increases the security of the product as well as the individual using it.

 4 Important Techniques of Assembly Testing

PCB assembly testing employs a plethora of techniques. However, there is no one technique that yields perfect results. The technique employed for your use has to be in accordance with your needs and environment. This is the only way to ensure that assembly testing yields appropriate results.

It is important to know the techniques of PCB assembly testing along with their pros and cons.

PCB Assembly testing service

1. Functional Circuit Test

Just as the name suggests, a functional circuit test assesses the function of the circuit. Towards the end of a manufacturing plan, a functional circuit test is run. This is one of the most comprehensive assessments for the circuit. It assesses the product as a whole without breaking it down into individual components. A functional circuit test helps to identify faults.

A wide variety of test environments are run for functional circuit tests. A variety of supply levels, frequencies as well as several other parameters are used to ensure the high specificity of the test.

Through the functional circuit test, faults in power integrity, signals, and current and voltage are identified. Test probes and test software are employed to determine the functionality of the product. Generally, after the functional circuit test, a product is either considered pass or fail.

There are a few shortcomings of this technique. It does not provide a detail of the bugs. It only identifies the pass/fails status of the product as a whole.

 2. Boundary Scan Test

It is the most versatile type of PCB assembly testing technique. It is primarily used for testing integrated circuits. All nodes of a circuit are not assessed in a boundary scan test. JTAG is the alternative and rather more specific term for referring to boundary scan tests.

The low cost is the primary advantage of the boundary test. This along with its access capabilities has led to the growing popularity of boundary scan tests.

In case you have a set of densely printed and highly complex circuit designs, it is wise to use a boundary scan test.

3. In-Circuit Test (ICT)

The in-circuit test is a test of the functioning of each component. To assess the overall product functioning, each product is separately tested. A set of test probes called a bed of nails is used to access the nodes on an assembly. ICT tests each component individually.

ICT due to the thorough testing feature is catches about 98% of the manufacturing faults. The equipment required for ICT is the software, fixture, and the in-circuit tester. It adequately measures the resistance and capacitance thus it is the best choice for testing analogue circuits.

The ICT method is a rather expensive one due to its high specificity. Thus, it would be more suited to use in the case of high-volume products. It is also good for testing the product in the latter stages.

4. Fixtureless In-Circuit Test (FICT)/Flying Probe Test

A PCB testing method that is just as competent as ICT but a lot less expensive? Well, that would be the flying probe test. It is primarily an ICT test but operating without fixtures has reduced the cost significantly. A software-controlled program and single fixture can smoothly run the flying probe test. A single fixture holds the board while test pins move and evaluate each of the components.

Despite being slower than ICT, the flying probe test has gained quite popularity. It is easy to use and cost-effective. Thus, it is more suitable for low-volume product testing.

The use of Electronic Board Repair Service for Printed Circuit Boards

A printed circuit board is the heart of any electronic device. They are the core element especially when manufacturing devices. An abnormality in printed circuit boards is the major reason behind the failure of the electronic gadget.

Printed circuit boards are not invincible to external conditions. This means that over time they get to experience the outer elements in one way or another. It means they can deteriorate as time passed and negatively affect their performance. The major causes for this wearing off can be due to elements, moisture, expiration of a period, and even a boost in the placement. Hence, there are several reasons that can account for circuit board abnormalities.

Fortunately, Electronic Board Repair Service can help by repairing and reinstating the circuit boards for betterment.  These services can allow in assisting the board towards reparation or totally use it in another device. This is a form of recycling that allows it to be compatible with a device whose load it can bear.


Moreover, before making the decision about the future functionality of the circuit board, the researcher needs to determine the cause of the failure. They need to find the root cause so that the problem doesn’t arise again. The identification of the problem can solve almost all the bugs in the circuit board.

Many researchers recommend knowing some common problems that associate with printed circuit boards. This is a sure short method of checking the circuit board with a set of first aid kit solutions. If all the commonly found problems rule out then they can further test the board for anomalies.

Thus, an Electronic Board Repair Service must know about all the common problems related to circuit boards. The following are some of them and their solutions for making immediate and effective corrections.

They provide in-house services that help determine the common causes of deterioration of the board. Some of those causes and their solutions are listed below for a better understanding.

 A Physical Damage to the Circuit Board

The most common reason for a circuit board to work improperly is due to physical damage.  In reality, most of the circuit boards that are not functioning properly have gone through some kind of physical damage.  Physical damage can be a cause of multiple reasons like taking a great fall, bearing a shock, or being hit by an external force.

In order to repair the physical damage, one needs to make sure that the circuit board has not completely failed.  After making sure that recovery is possible, it is likely to fix the board by remanufacturing its components.  The service team can use the process of melting the damaged parts and repairing them.

They can assemble the parts in their original state by using the art of remodeling and soldering at certain joints. This helps in achieving the original shape of the board.

Failure of a Component of the Circuit Board

The second possible reason for device failure in functioning properly is due to a component failure. We already know that circuit boards consist of different components like transistors, diodes, and other such parts. It is possible that one or more of these parts are faulty.

If the circuit board has not faced any physical damage then the probability is that there is a part within the circuit board that is defective. In order to determine the component that is catering to the device failure, the service team needs to open up the circuit board.

Once the part or area that is the cause of failure is conclusive, they can fix it using their repairing techniques.  In most cases, they can use soldering techniques in repairing the particular part.  After testing the faulty part with thoroughness the circuit board is as good as new.

Poor Designing of the Circuit Board

Another factor that may cater to electronic failure is the poor design of the circuit board. As minuscule as it may seem, the design structure of the circuit board carries great significance. Even after finding the fault in a poor design, there is a high probability that the device may lead to failure yet again.

This is why it is important to use circuit boards from well-reputed brands such as 6PCBA. It is best to replace the entire board rather than wasting time over its service again and again.

Electronic Board Repair Service


The idea behind using a repairing service for electronic boards is very intelligent.  There are many reasons why an electronic device leads to failure.  Most probably the reason lies in faulty circuit boards.  Detecting some common reasons behind electronic failure can help in remanufacturing the boards for proper functioning.


Importance of PCBA Functional Testing

Advantages of PCBA Functional Testing

In every other state-of-the-art PCBA manufacturing unit, there is a proper PCBA functional testing facility. This facility ultimately helps in realizing and making it possible to have a quality PCBA circuit board. The presence of such units is critical in assuring the quality production of circuit board assemblies. Hence, those who like to import such circuit boards must run the quality test to ensure the functionality and behavior of the assembly.

Testing is the only method that allows the importers to make sure the product he is ordering or paying for is worth being imported. Hence, with the collaboration of the manufacturer, functional testing becomes imperative for the importers. Therefore, the process appears to be a grand strategy to make sure the product bears full test coverage in the manufacturer’s vicinity. Read more about PCBA testing methods here

PCBA functional testing

What Is PCBA Functional Testing?

To understand the importance of PCBA functional testing, it becomes imperative to first understand what is Functional Testing for PCBA. During the phase of manufacturing the PCBA circuit unit eventually has to go through steps of inspections for quality assurance. These steps are the various methods by which a circuit has to pass. These are called multiple inspections. It thereby includes visual inspections, semi-automated bench testing, flying probe test, and In-Circuit tests (ICT) as well. The purpose of these testing phases is to analyze whether it is time for the PCBA circuit board to leave the factory and to be shipped to the actual customer before its production. To ensure quality, reliability, and durability, the PCBA functional testing becomes integral. Also, the purpose includes finding the defects that can affect the reliability, missing components, faulty joints or connections, etc.

However, amongst all the available variety of testing, the PCBA functional testing appears to be the most comprehensive of them all. It eventually verifies the proper signal behavior which seems to be missing in other methods. By comprehensive, it means that using this method, it will be a situation of announcing Go or No-Go signal or decision for the Fabricated PCB circuit. The issues related to signal problems in PCBA functional testing are:

Integrity Of the Power Signals

Power integrity amongst the PCBA signal is the most common as it happens due to various factors including an excess of ripples in PDN during operations, excess of jitters as well as low noise frequency.

Distortion of Signals

There are various nets where distortion of signals happens. It eventually includes various nets and skews in buses that cause signal distortion along with other behaviors as well.

Inaccurate Voltage/Current:

The reason behind the inaccurate amount of current or voltage is due to the addition or installation of incorrect components. It nonetheless also happens if one of the components is missing from the circuit board. Lastly, if IR drops in a circuit board, the amount of current or voltage also drops.

Despite the number of methods and procedures to have successful functional testing, there nevertheless must be a fixture for the PCBA board. It thereby only allows having comprehensive PCBA functional testing. Having a proper fixture thus allows the manufacturer to examine all the required areas. However, the presence of such a fixture appears to carry a hefty price tag. The amount of price also increases more if a manufacturer uses an embed software. It is because the software requires a written program to run. Nonetheless, with the use of embedded software, the surety to have high quality and the high yielded product is a guaranteed phenomenon.

PCBA functional testing

Benefits Of Using PCBA Functional Testing

There are two major benefits of using the PCBA functional testing in Printed circuit boards. It includes Quality Assurance and Improvement of Process and Reduction of Production Costs. Let us discuss each benefit in detail:

Assurance Of High-Quality Product

If we look at the In-Circuit Testing as ICT, we come to know the point that it carries an evaluation of individual components and the characteristics of each electronic component. However, this is not the case when it comes to PCBA functional testing. Instead, the process alternatively involves the connection of a finished PCBA circuit with the system to run the entire cycle of processes to ensure functionality in full swing. For testing, the quality assurance engineer monitors the device using the Device Under Test method. By using the method, the engineer learns its performance and gathers all the necessary data to evaluate the whole design.

The functionality test makes sure the design is properly performing all the necessary functions as is expected from it. It, conversely to the ICT test, allows testing the design only through the connector interface level. By using these connections, one can eventually execute the test. The functionality test thereby confirms the connection and interaction between various components in a manner that is expected to work for the end-user as well. The reason for performing the functionality test is to analyze the errors. Then to correct and isolate those errors and defects quickly. After that, it is the priority to resolve those defects and make them run perfectly.

Improving The Process and Reducing the Production Cost

One of the imperative things to keep in mind is that not all the PCBA functional testing for PCBA circuit boards is identical. It is because the implementation of these tests varies widely with the change of products. For every other product in DUT, the parameters for testing the signals in PCB circuits is different. However, the necessity and importance of the test remain a high priority. In addition, it is, therefore, a recommendation to avoid taking and covering huge space and resources for multiple systems.

Furthermore, the addition of a universal functionality testing system is a blessing. The system thereby allows reduces your space and cost. This moreover reduces the number of workers and operators to operate a variety of system thereby reducing the cost, salary as well as it maximizes the overall value and profit. Therefore, to get benefits by using the testers, it is important to provide the manufacturing partners with a list of exact functions and parameters. In this way, the company then proposes the right universal product and tester for your brand.

These are some of the suggestions regarding the PCBA functional testing. However, to read more about various types of testers and PCBA design, feel free to contact our customer support services here
