PCB Manufacturing Process: All You Need to Know

Creating a printed circuit board (PCB) is a systematic process that begins with meticulous design and material selection, crucial for ensuring functionality and durability. The initial steps involve the application of a thin layer of copper over a substrate material, typically a fiberglass substrate reinforced with epoxy resin and glass fiber, which provides the necessary rigidity and electrical insulation. This copper layer is then patterned to form conductive areas that will eventually carry electrical signals.

The layout design process utilizes advanced CAD software for precision, ensuring that the conductive paths and component placement areas are accurately defined. Once the design is finalized, it's transferred onto the PCB using photo reactive chemicals and UV exposure, a process known as outer layer imaging. This method allows for the precise alignment of layers and the creation of intricate circuit patterns.

After the design transfer, the excess copper is removed through a careful etching process, leaving behind the copper traces that form the circuitry. The PCB then undergoes a laminating process to apply a solder mask, a protective layer that covers the entire board while exposing the areas where components will be soldered. This solder mask application is crucial for preventing short circuits and ensuring the longevity of the PCB.

Following the application of the solder mask, a silkscreen printing process adds labels and markings to the PCB, aiding in component placement and board identification. The final step in the fabrication processes involves applying a surface finish, such as tin plating, to protect the exposed copper and ensure a reliable soldering surface. Other surface finishes like HASL (Hot Air Solder Leveling) or ENIG (Electroless Nickel Immersion Gold) are also used depending on the application requirements.

Throughout the PCB manufacturing process, precision is maintained through the use of technologies like CNC machines for accurate drilling of holes that will accommodate electronic components. Each part of the PCB fabrication process, from the initial design to the final surface finish, is critical to enhancing the PCB's electrical performance and longevity.

The final stages of assembly involve the placement of components onto the PCB, often by a contract manufacturer specializing in PCB assembly. This is followed by soldering, which can be done through various methods, to securely attach the components to the board.

Rigorous electrical tests are conducted to validate the PCB's performance, ensuring that it meets stringent quality standards before integration into electronic devices. These tests verify the integrity of the conductive paths, the correct orientation of components, and the overall functionality of the PCB.

This holistic approach underscores the importance of meticulous craftsmanship and thorough quality assurance in producing reliable PCBs that power our modern gadgets effectively. Each step, from the initial plating process to the final surface finishing, contributes to enhancing the PCB's electrical performance and longevity, making it a vital component in the electronics industry.

[oldguydoesstuff]

Bare CPU Printed Circuit Board for the Alpha NT XL366 workstation I designed back in 1995 or so. This was an obscure model of an obscure product line, made by a company (Digital Equipment Corp.) that is now itself obscure. To be honest I don't even remember much about this machine now.

What I do remember is the HUUUUGE fight I got into with our Signal Integrity team while I was designing this, over decoupling capacitors.

Decoupling caps are small components that hold a charge to help even out power when a circuit is active. This board featured hundreds of them, smaller than a grain of rice (see photo comparison of mounting pads vs rice grain below).

Our Signal Integrity team was tasked with making sure everything was electrically stable, so they required many hundreds of these to be added to the board, based on power simulations they did. Trouble was, they wanted so many, we couldn't even build the board.

My job as the Systems Engineer here was to meet the requirements from the SI team, but also from manufacturing, and the requirement that my PCB layout techs don't go insane trying to place and route the board. SI really only cared about signal quality, so they would not relent, and I ended up getting shouted at at one point by a junior SI engineer who was also under a lot of stress, when I said "There are different schools of thought on this.." and he screamed THERE ARE NOT DIFFERENT SCHOOLS OF THOUGHT ON THIS!!

It got to the point where the product was not going to get built, because we just couldn't fit like a thousand of these tiny caps on the board, we needed to ditch at least 25% of them to have a hope. The models were the models though, and you couldn't argue against them.

But then my boss got a genius idea. What if we could prove the simulation models were too conservative? We came up with an experiment where we would remove caps from an older system and measure the power supply noise, to see how many caps could be taken off before the system became unstable.

Me and the junior SI engineer were tasked with doing this experiment (later deemed The Decapitation Project), so we grabbed a Tektronix scope and Metcal soldering station and headed over to this abandoned lab we had in our old Maynard headquarters, a now creepy attic space on the 6th floor of an old mill building. Here were a few older Alphastation 3000 workstations we built years earlier, working but waiting to be recycled.

We had this special program that would thrash the CPU within an inch of its life, to put a big demand on the power supply system. While this was running, the SI engineer measured the power quality, while I proceeded to (very carefully to avoid short-circuiting the system) actually desolder caps from the board while the workstation was running.

We managed to get about 1/3 of them off before there was any noticeable effect, and we found one specific type of cap was not doing much of anything at all. We took the data back to the head of the SI team, and he finally relented and let us remove several hundred capacitors. (He also buried the report and data I had, because he didn't want the bad publicity - I remember being mad about that)

The system got built after that, and worked just fine. We did try to enact a small bit of petty revenge on the SI team manager though - there was a recognition event for people involved on the project, and me and our PCB procurement guy decided to give the SI team manager a special "Faraday Award" for achievement in capacitance (Farads are a measure of capacitance - geeky eng joke). We took an old bowling trophy with a giant, beer-can sized electrolytic capacitor strapped to the top of it as the award. He was a no-show so we didn't get to present it. Those SI guys never did have much of a sense of humor.

Anyway, long story sorry. Just thinking of it recently because I was helping someone at work with an analog simulation and I remembered this..

[juh-wasnt-deactivated19691231]

finally!! finished the guitar pedal my dad got the kit for like a year and a half ago

i redesigned it from scratch because the construction of the original clone was annoying and i think it’s dumb that guitar pedals sometimes use reverse-polarity power and you’re just supposed to guess, so this one takes either polarity through the same jack.

photographic evidence of how this distortion pedal works! based on the Proco RAT of 70s fame, essentially we just clip the signal peaks to introduce other frequencies, which make up the distortion we hear. the FFT on my scope didn’t show much, but either i didn’t tune it right or the instrumentation is just limited here, because we can see pretty clearly the flattened peaks on the processed signal (2, 3) compared to the input (1).

i learned some things about design for manufacturing (DFM) from this project, not just from the original clone board but also from shortcomings of my own design (it turns out that’s a LOT of wires to manage in that small space). if i did it over, i’d put the pins on a 0.1” pitch grid across the board, probably use larger components, and take more care in choosing the shape of the PCB to fit the enclosure around all the hardware. I might even have split it up into a few tiny boards! just for kicks. i also probably would have soldered wires onto the kick switch at an angle, so that they’re not stressed or bent on their way to their final configurations.

the light pipe in particular was a challenge because it turned out the cap on the pipe was small enough that it would slide all the way through the hole meant for a THT LED. I could have fixed this with a washer if I had one, but I eventually hot glued a nut to the cap and let it be.

big thanks to my friends and partners including @thinkpadt530 who helped me with this! i learned a lot from them all, and definitely would not have finished without them. <3

Ultimate Guide to PCB Testing Methods: Ensuring Quality and Reliability in Your Circuits

In the electronics sector, Printed Circuit Boards (PCBs) are the life-lines of virtually all gadgets that are in use in the modern society. From humble home appliances to gigantic industrial equipment, PCBs are the skeletal framework of hardware organization and connection of circuit elements. It is vital to guarantee the quality and dependability of these fundamental parts – thus enters PCB testing methods. It is our hope that this extensive hand will help identify the most suitable test strategies for PCB testing, why these techniques matter, and how to maximize your circuits’ functionality.

Introduction

Firstly, an increase in the capability of different electronic devices leads to higher necessary requirements to the PCBs used in their production. Performing tests on the PCBs is an essential step in the manufacturing process done to confirm that a given board performs as a unit to the expected levels. This guide aims at explaining various techniques of PCB testing with a view of having a better understanding on how to achieve quality and reliability on the circuits.

Why PCB Testing is Crucial

PCB Testing When it comes to the potential defects on PCBs, there are shorts, opens, and some component placements. They can cause device failure, decline in performance level, and sometimes also pose safety issues. Through high-quality testing regimes, it becomes easier to address problems before they reach the customer, and thus manufacturers will have reliable and efficient products. Key reasons for PCB testing include:

Detecting Manufacturing Defects: Solder bridges, missing and placed in wrong position components, all can be detected in the initial stages easily.

Ensuring Functionality: Ensuring that the PCB does what is wanted and needed when it is in use, and under several conditions.

Quality Assurance: Ensuring that the business meets industry standards, and what clients require of them.

Cost Efficiency: Decreasing the likelihood of rework and recall by identifying possible defects before they get to the customer.

Types of PCB Testing Methods

These are the types of PCB Testing Methods:

Visual Inspection

Technique one as also referred to as the VI or visual inspection is the simplest and basic type of testing done on PCBs. The technique entails inspecting the board with naked eyes for some of the common faults including solder bridges, missing parts, and misalignment issues.

Automated Optical Inspection (AOI)

AOI employs cameras and software algorithms to check PCBs for defects and performs the inspections singly. This method of inspection is far more efficient than the manual inspection and simultaneously versatile enough to identify numerous problems.

X-ray Inspection

Some functions which include examination of features of BPCs that could not be easily inspected include solder joints under components through x-ray inspection. It is especially effective in inspecting defects in BGA (Ball Grid Array) and other various packages as well.

In-Circuit Testing (ICT)

ICT entails applying different voltage across the PCB to checks on the electrical characteristics of the needy part and connections. The use of this method is highly recommended for the identification of functional problems and verification of the circuit’s goodness.

Functional Testing (FCT)

Functional testing evaluates the effectiveness of the PCB pointing to the fact that it can be tested when placed in use. This method enables the certification of that the PCB works as expected under actual environment.

Flying Probe Testing

In flying probe testing, the probes are moved around to test the electrical properties of the created PCB. Lower to medium volume production runs can be made easily by using this technique; hence it is advantageous in this regard.

Boundary Scan Testing

Boundary scan testing also called as JTAG testing extends test circuitry into all the components for testing the connections between them. Although, this method is very efficient for identifying connection problems and faults.

Burn-In Testing

Burn-in testing puts the PCB in a state of operational stress for a long time to capture early-life failures. This aspect makes the method reliable for the long term since it is likely to identify problems that may occur when the equipment is in use for a long time.

Perhaps stressful to the board

Choosing the Right Testing Method

The choice of the appropriate method of PCB testing can be influenced by several factors such as the level of complexity of the PCB and the numbers of boards to be tested as well as the actual costs of the testing process and other features. Consider the following when choosing a testing method:

Board Complexity: Great board densities or component placement can be a determinant as to whether one needs AOI or X-ray inspection.

Production Volume: Applications that are characterized by high volumes can be easily facilitated by ICT while the low to medium volume applications may require flying probe testing.

Budget: Both manual inspection and AOI are favorable for various production volumes, while X-ray and ICT are more expensive at the beginning.

Specific Requirements: There are two types of the test, namely Functional Test and Burn-In Test that should be made so as to attain the long term reliability in applications that are critical.

Best Practices for PCB Testing

Using the best techniques in testing PCBs increases the quality and reliability of the circuits that you are working on. Here are some key practices to follow:

Early Testing: It is recommended to carry out the tests when the product is still in its design and manufacturing phase so that problems can be noted earlier before they reach a very catastrophic level.

Automate Where Possible: Use method such as automation to reduce the time and improve on the quality of the testing.

Regular Calibration: It is necessary to check if all the testing equipment used for calibration are accurate.

Comprehensive Coverage: This way, you will be able to ensure that there are no defects that are not tested as the best testing approach combines all types of testing methods.

Document Everything: Ensure that you keep records of the tests performed, the results obtained, as well as any measures taken to correct the breaches.

Common Challenges and How to Overcome Them

These are the common challenges and how to overcome them:

False Positives/Negatives

Automated testing methods maybe good some times, they give you the results that are either positive or negative and this will lead to unnecessary rework or more alarming leaving critical defects unfound. In order to avoid this, make sure that testing algorithms and testing equipment are updated and fine-tuned from time to time.

Component Access

Some of the testing techniques involve handling parts of the circuit and with high density board this can be very difficult. Some of the ways in which testbench implementation can be avoided are as follows Boundary scan testing and X-ray inspection.

High Costs

Some form of testing such as X-ray and ICT testing is often very costly. The effectiveness must come with reasonable prices; try to combine some of the mentioned approaches to cover all the aspects without spending too much money.

Future Trends in PCB Testing

About the future, it can be stated that its trends will be in fact linked to the tendencies in technologies and expectations towards ever higher quality and quantity of tested PCBs. Key trends to watch include:

AI and Machine Learning: Using of intelligence algorithms and machine learning in testing algorithms to enhance the efficiency and the minimization of false negative or false positives.

IoT and Smart Manufacturing: Higher testing flexibility and opportunities for the continuous test process supervision.

Advanced Imaging Techniques: The need for better techniques that would enhance the detection of defects within a printed circuit.

Environmental Stress Testing: More focus in the testing of PCBs under different environmental pressures in order to improve on its longevity.

Conclusion

Quality and reliability of packaged circuits have to be maintained to contribute positively in any electronic equipment. This paper seeks to explain the common testing techniques for PCB so that PCB manufacturers are able to test and see if they are free from defects and if they are functional. This ultimate guide will give you a full insight on the available options in PCB testing that will enable you make the best decision that will give you perfect circuits.

Printed Circuit Board Basics

Most of us are using Printed Circuit Board in our daily life. Printed Circuit Boards are used in almost all the Electronic products, from consumer gadgets such as PCs, tablets, smartphones, and gaming consoles to industrial and even high tech products in strategic and medical electronics domains.

Here, we have some statistics for you that shows how many electronic devices connect worldwide from 2015 to 2025. This statistic shows an increase in the use of a number of PCB in people daily life. Hence, CircuitWala took this opportunity to provide a basic knowledge about PCB via this article.

There are so many books available online which teach about Printed Circuit Board design and hardware part. There are few links available online which shows only a few basic fundamentals of PCB and few are there for Basics of Printed Circuit Board (PCB) Design. Few which gives good know knowledge on Printed Circuit Board terminology. But in the end for the hobbyist, there is no such material available which make their work easy.

Now days there few online designing websites available which allow hobbyist and students to create their design and Printed Circuit Board fabrication part. These websites provide limited features and charge high for the full edition. We, @CircuitWala are in try to provide one platform which provides plenty of Printed Circuit Board knowledge digitally to make your work simple and easy.

Alternatives of PCB include wire wrap and point-to-point construction. Creating a layout of PCB is a little bit time-consuming method as compared to its alternative solution but manufacturing of PCB is cheaper and faster then other wiring methods as electronic components are mounted and wired with one single part.

Let’s start with some basics of Printed Circuit Board with this article. Here in this article we will discuss about history of PCB to understand the emerge of PCB, Types of PCB to make your complex PCB a very simple using different types, Usage of PCB to provide you an idea to create more Printed Circuit Board projects, Advantages and Disadvantages, Possible Future to know about new technological change in Printed Circuit Board manufacturing and also about how to destroy and manage your PCB’s e-waste? We know you are eager to know all the stuff in details but before that let’s make a simple definition of Printed Circuit Board.

What is Printed Circuit Board?Printed Circuit Board is an electronic device made of conductive material(FR-4) like copper which connects components mounted on it to to get desired output by providing an input on another end.

When the board has not mounted with any of the components is called as Printed Circuit Board or Printed Wired Board. Mounting of an electronic component on Printed Circuit Board is called as PCB assembly.

History of Printed Circuit BoardThe invention of Printed Circuit Board was by Austrian engineer Paul Eisler as part of a radio set while working in England around 1936.

In early days before Printed Circuit Board became common in use, Point-to-Point construction was used. This meant some bulky and unreliable design that required plenty of sockets and regular replacement of it. Most of this issue directly address when PCB went into regular production.

Originally, every electronic component had wire leads, and the PCB had holes drilled for each wire of each component. The components’ leads were then passed through the holes and soldered to the PCB trace. This method of assembly is called Through-Hole construction. There is one other method to mount component is called as Surface Mount.

Type of Printed Circuit BoardPCBs are produced from the different types of material and on the basis of that material PCBs are divided mainly into two parts: Rigid PCB and Flexible PCB. Nowadays, a combination of Rigid and flexible PCB is also possible and that is called as Flexi-Rigid PCBs.

Most of the PCBs are built in layers. The inner layer is the base material called as a substrate. Rigid PCBs are mainly made of material like epoxy materials and Flexible PCBs are made of plastic material that can withstand high temperatures.

Rigid PCBs are generally, hard materials that hold the component in a better way. The motherboard in the tower of a computer is the best example of Rigid PCBs. Flexible PCBs fundamental material allows PCB to fit into forms that Rigid PCBs can not. Flexible PCBs can turn round without harmful the circuit on PCB.

All Rigid and Flexible PCBs can come in three formats by layers: Single Layer, Double Layer, and Multi-Layer.

1. Single Layer PCBSingle Layer PCBs have been around since the late 1950s and still dominate the world market in sheer piece volume. Single Sided PCBs contain only one layer of conductive material and are best suited for low-density designs. Single-sided PCBs are easy to design and quick to manufacture. They serve as the most lucrative platform in the industry.

2. Double Layer PCBDouble Layered printed circuit board technology is conceivably the most popular type of PCB in the industry. Double Sided PCB (also known as Double-Sided Plated Thru or DSPT) circuits are the gateway to advanced technology applications. They allow for a closer (and perhaps more) routing traces by alternating between top and bottom layers using vias.

3. Multi Layer PCB

Multilayer PCB is a circuit board that has more than two layers. Unlike a Double-Sided PCB which only has two conductive layers of material, all multilayer PCBs must have at least three layers of conductive material which are buried in the center of the material.

Usage of Printed Circuit BoardBy reading this article till this point, we hope that you are now able to get about printed circuit boards. Now, we will make you understand about different applications of printed Circuit Board.

In this digital world, Printed Circuit Board is in almost all our daily life electronic devices and in our industrial electronics as well. Below are the industries where PCBs are used:

Possible FutureNowadays, most of the circuits are replaced to produce Printed Circuit Board from the old methods. Revolution in technology made many of the processes automated and hence it is easy to manufacture PCB. But still, these processes are a bit expensive to hire, involve toxic waste and use high temperatures and acids. With technological advances we have seen in the past years, it is not hard to imagine PCB will soon be revolutionized. Not only that but research institutes predict a more ‘green’ future for PCBs; PCBs being made of paper.

Electronic Waste (e-waste)Electronic Waste or e-waste is described as discarded electrical or electronic devices. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution.

Electronic scrap components contain a hazardous substance such as lead, cadmium, beryllium, or brominated flame retardants. Recycling and disposal of e-waste may involve significant risk to health of workers and communities in developed countries and great care must be taken to avoid unsafe exposure in recycling operations

Nowadays, developing countries are encouraging electronic users to take care while recycling the e-waste or submit them to the organization who are involved in such activities.

SummaryIn this blog, we have learned the basics of Printed Circuit Board. CircuitWala is planning to write as many blogs to provide more and more knowledge of Printed Circuit Board. Either it is basics or manufacturing or usages or advantages and disadvantages of PCBs. We will also try to make our users/customers up to date for the new technology innovations, including past histories and revolution of the PCB industries.

In the next blog, we will look at more briefly about the different types of Printed Circuit Board. We also understand the process to make it and different usage and application for the same.

What are the benefits of a prototype PCB assembly?

Prototype PCB assembly comes with several advantages. These benefits play a major role in the facilitation of your PCB manufacturing. Some of these benefits include:

Detection of Flaws Early

With prototype PCB, you will easily detect whatever flaws are present during the product’s development stages. This will allow you to solve the issues thereby saving you some money if you had gone ahead to make the production having the flaws in them.

If you go ahead to make changes during the production, there may be a need for more technicalities, and this may be expensive.

Testing of Each Component

With a prototype, you will be able to test all your system’s elements individually before you go ahead to set it up. You should do this because it is important especially for very complex projects composed of several parts that are PCB based.

When you validate each of these components, you will be able to identify those areas having issues that you should look into. This is the only way the project can function the right way.

Reduction in Total Costs

Utilizing the prototype bare PCB for any of your projects could go a long way in reducing what you’ll have spent in total for the project. With prototyping, you will be able to notice those errors in your project and then make corrections before you start the real production.

As soon as these flaws have been checked and rectified, then you may continue with the manufacturing of your Printed circuit boards in large quantities, thereby saving you unnecessary costs.

High-Quality PCBs

Why prototyping your PCB is important is to help you test if your project will function effectively. When we talk of testing, it involves the identification of errors present and then rectifying and making corrections to them.

Therefore, the eventual PCB after the prototyping will be of high quality that surely meets standards set internationally.

Less Turnaround Time

With prototype PCB assembly, you will be able to reduce the total time used in producing your printed circuit board. While making use of prototype printed circuit boards, you’ll be able to see the errors and then make corrections before you start the actual production.

Therefore, the eventual prototype will be free of defects. This implies that your PCBs will be produced quickly by your manufacturer.

What is PCB Assembly ?

PCB Assembly manufacturer - Hitech Circuits Co., Limited

 It’s the step in the manufacturing process in which you populate a blank board with the electronic components needed to make it into a functional printed circuit board. It’s these components that make a board into the circuit that enables an electronic product to function. PCB assembly typically takes place via one of two processes:

1. Surface-mount technology

SMT: SMT stands for “Surface Mount Technology“.  The SMT components are very small sizes and comes in various packages like 0201, 0402, 0603, 1608 packages for resistors and capacitors. Similarly for Integrated circuits ICs we have SOIC, TSSOP, QFP and BGA.

The SMT components assembly is very difficult for human hands and can be time taking process so it is mostly done by automated pick and place machine.

2. Through-hole manufacturing

THT: THT stands for “Through hole Technology”. The components with leads and wires, like resistors, capacitors, inductors, PDIP ICs, transformers, transistors, IGBTs, MOSFETS are example.

The component has to be inserted on one side of PCB and pulled by leg on other side and cut the leg and solder it. The THT components assembly is usually done by hand soldering and is relatively easy.

Printed Circuit Board Assembly Techniques

There are only two common PCBA techniques available for use by a PCB designer. The methods are:

1. Automated PCB Assembly Techniques

Generally, this technique employs the use of state of the art machines, which are fully automatic. For example, the surface mount components are worth positioning with the aid of an automated pick and place machine.

Again, reflow soldering is commonly for surface mount components usually done in a reflow oven. An automated solder stencil is also used to apply the solder paste on the PCB.

Finally, high tech inspection machines are used to confirm and check the quality of the PCBA. Some of which include: Automated optical inspection machine (AOI), X-ray inspection machines, etc.

Above all, due to the precise monitoring, control of soldering, no human input and versatile machines.

This technique ensures utmost efficiency, output consistencies, and limits defects.

2. Manual PCB Assembly Techniques

This method is favorite for use with through-hole parts, which needs manual placement on the board. Besides, with these through-hole parts, it’s advisable you use wave soldering. Note that in the through- hole assembly process, you need to place the components and electronics on the PCB.

After that, you use wave soldering to solder the leads. Typically, you will need an individual to insert a component into a marked PTH. Once done, transfer the PCB to the next station where the next person will be on standby tasked with fixing another part.

What are the Benefits of SMT PCB Assembly?

SMT assembly provides many benefits and some of them are as follows:

It can be used to incorporate small components.

In SMT, the components can be placed on both sides of the board.

It assures high component densities.

Fewer holes need to be drilled for surface mounting than through-hole.

It require low initial costs and time for setting up the mass production.

SMT is the simpler and faster-automated assembly when compared to through-hole.

Errors regarding the component placement can be easily rectified. 

Surface mount  PCBs feature strong joints, which can easily withstand vibrations. 

What are the techniques used in Surface Mount Technology?

There are several techniques for the reflow process. After applying the solder paste or a flux mixture on the board and after placing the components, the boards are conveyed to a reflow soldering oven. The techniques used for reflowing soldering include infrared lamps, hot gas convection, fluorocarbon liquids with a high boiling point, and so on.

What are the different testing methods used in SMT PCB Assembly?

Hitech Circuits as the PCB assembly manufacturer, we perform the following testing and inspection to ensure the quality of surface mount PCBs.

Automated Optical Inspection (AOI): This is performed before and after the soldering to identify the component placement, presence, and solder quality.

X-ray Testing: In this type of testing, the operator relies on the X-ray images of the PCB to check the solder joints and lead-less components such as Quad Flat Packs and ball grid arrays, which are generally not visible to naked eyes.

In-Circuit Testing (ICT): This method is used to detect manufacturing defects by testing the electrical properties in the SMT Assembly.

What type of files or documents should I send for SMT PCB Assembly? 

Gerber Files: The file contains all details of physical board layers including solder masks, copper layers, drill data, legends, and so on.  

Bill of Materials (BOM): This contains information on the list of items needed for the PCB manufacturing and the instructions of manufacturing. 

Pick and Place File: This file contains information on all components to be used in the PCB design and their rotation and X-Y coordinates.

The whole process of PCB Assembly

1. Bare board loader machine

The first step in the PCB assembly is to arrange the bare boards on the rack, and the machine will automatically send the boards one by one into the SMT assembly line.

2. Printing solder paste

When PCB on the SMT production line, firstly, we have to print solder paste on it, and the solder paste will be printed on the pads of the PCB. These solder pastes will be melt and solder the electronic parts to the circuit board when it passes through the high-temperature reflow oven.

In addition, when testing new products, some people will use film board/adhesive cardboard instead of solder paste, which can increase the efficiency for adjusting the SMT machines.

3. Solder paste inspection machine(SPI)

Since the quality of solder paste printing is related to the quality of welding of subsequent parts, some SMT factories will use optical machine to check the quality of solder paste after printed the solder paste in order to ensure stable quality. If there any poorly printed solder paste board, we will wash off the solder paste on it and reprint, or remove the excess solder paste if there is redundant solder paste on it.

4. High speed SMT machine

Usually, we will put some small electronic parts (such as small resistors, capacitors, and inductors) to be printed on the circuit board first, and these parts will be slightly stuck by the solder paste just printed on the circuit board, so even if the speed of printing is very fast and the parts on the board will not fall away. But large parts are not suitable for use in such high speed SMT machines, which will slow down the speed of small parts assembly. And the parts will be shifted from the original position due to the rapid movement of the board.

5. Universal SMT machine

Universal SMT machine is also known as "slow machine", it will be assembled some large electronic components, such as BGA IC, connectors, etc., these parts need more accurate positions, so the alignment is very important. Use a camera to take a picture to confirm the position of the parts, so the speed is much slower than High speed SMT machine we taked before. Due to the size of the components here, not all of them are packed in tape and reel, and some may be packed in trays or tubes. But if you want the SMT machine to recognize the trays or tube-shaped packaging materials, you must configure an additional machine.

Generally, traditional SMT machines are using the principle of suction to move electronic parts, and in order to place the parts successfully, and there must be the flat surface on these electronic components for the suction nozzle of the SMT machine to absorb. However, for some electronic parts don’t have a flat surface for these machines, and it is necessary to order special nozzles for these special-shaped parts, or add a flat tape on the parts, or wear a flat cap for thees electronic parts.

6. Manual parts or visual inspection

After assembled all parts by the high speed SMT machine or Universal SMT machine and before going through the high-temperature reflow oven, and we will set up a visual inspection station here and to pick out the deviation parts or missing components boards etc., because we have to use a soldering iron to repair if there are still defectives boards after passing the high-temperature oven, which will affect the quality of the product and will also increase the cost. in addition, for some larger electronic parts or traditional DIP parts or some special reasons cannot be processed by the SMT machine before, they will be manually placed on pcb here.

7. Reflow oven

The purpose of reflow oven is to melt the solder paste and form a non-metallic compound on the component feet and the circuit board, that means to solder electronic components on the circuit board. The temperature rise and fall curves often affect the soldering quality of the entire circuit board. According to the characteristics of the solder materials, usually the reflow oven will set the preheating zone, soaking zone, reflow zone, and cooling zone to achieve the best soldering effect.

For example, the melting point for SAC305 solder paste with lead-free is about 217°C, which means that the temperature of the reflow oven must be higher than the melting points to remelt the solder paste. What's more, the maximum temperature in the reflow furnace should not exceed 250°C, otherwise many parts will be deformed or melted because they cannot withstand such a high temperature.

Basically, after the pcb passed through the reflow oven, the assembly for the entire circuit board is almost complete. If there are hand-soldered parts, we need to transfer to DIP process, and then we have to check the quality after reflow oven by QC department.

8. Automatic optical inspection(AOI)

The main purpose of setting up AOI is because some high density boards can’t be process the following ICT test, so we used AOI inspection to replace it. But even using AOI inspections, there still have the blind spots for such checking, for example, the solder pads under the components cannot be checked by AOI. At present, it can only check whether the parts have side standing issue, missing parts, displacement, polarity direction, solder bridges, lack of soldering etc., but cannot checking the BGA solderability, resistance value, capacitance value, inductance value and other components quality, so far AOI inspection can’t completely replace ICT test.

Therefore, there is still some risk if only AOI inspection is used to replace ICT testing, but ICT test is also not 100% make sure the good quality, we suggest these two ways can be combined with together to make sure the good quality.

9. PCB unloader machine

After the board is fully assembled, it will be retracted to the unloder machine, which has been designed to allow the SMT machine to automatically pick and place the board without damaging the quality for PCB.

10. Visual inspection for finished products

Normally there will be a visual inspection area in our SMT production line whether there is an AOI station or not, and it will help to check if there are any defectives after completed assembled the pcbs. If there is an AOI station, it can reduce the visual inspection worker on our SMT line, and to reduce the potential cost, and because it is still necessary to check some places that cannot be judged by AOI, many SMT factories will provide the mainly visual inspection templates at this station, which is convenient for visual inspection worker to inspect some key parts and polarity for components.

11. DIP process

DIP process is a very important process in the whole PCBA processing, and the processing quality will directly affect the functional for PCBA boards, so it is necessary to pay more attention to the DIP process. There are many preliminary preparations for DIP process. The basic process is to re-process the electronic components first, like to cut the extra pins for some DIP components, our staff received the components according to the BOM list, and will check whether the material part numbers and specifications are correct or not, and performs pre-production pre-processing according to the PCBA samples. The steps are: Use various related equipment (automatic capacitor pins cutting machine, jumper bending machine, diode and triode automatic forming machine, automatic belt forming machine and other machines) for processing.

12. ICT test

Printed Circuit board open/short circuit test (ICT, In-Circuit Test), The purpose of ICT test is mainly to test whether the components and circuits on the printed circuit board are open or short issues. It can also measure the basic characteristics of most components, such as resistance, capacitance, and inductance values to judge whether the functions of these parts are damaged, wrong parts or missing parts etc. after passing through the high-temperature reflow oven.

ICT test machines are divided into advanced and basic machines. The basic ICT test machines are generally called MDA (Manufacturing Defect Analyzer). It’s just to measure the basic characteristics of electronic components and judge open and short circuits issue we talked above.

In addition to all the functions of the basic ICT test machines, for advanced ICT test machine can also test the whole PCBA by using power, start to testing the PCBA boards by setting the program in the test machine. The advantage is that it can simulate the function of the printed circuit board under the actual power-on condition, this test can partly replace the following functional test machine (Function Test). But the cost for the test fixture of this advanced ICT test can probably buy a car, it’s too expensive and we suggest it can be used in mass production products.

13. PCBA function test

Functional testing is to make up for the ICT test, because ICT only tests the open and short circuits on the the PCBA board, and other functions such as BGA and other fuctions are not tested, so it is necessary to use a functional testing machine to test all functions on the whole PCBA board.

14. Cutting board (assembly board de-panel)

Normally, printed circuit boards will be produced in panel, and it will be assembled to increase the efficiency of SMT production. It means several single boards in one panel, such as two-in-one, four-in-one etc. After finished all the pcb assembly process, it needs to be cut into single boards, and for some printed circuit boards with only single boards also need to cut off some redundant board edges.

There are several ways to cut the printed circuit board. You can design the V-cut using the blade cutting machine (Scoring) or directly manually break off the board (not recommended). For more high density circuit boards, it will be used the professional splitting machine or the router to split the board without any damage the electronic components and printed circuit boards, but the cost and working hours will be a little longer.

2. Dry ice pellet machine（Dry Ice Granulator Machine）:

        Dry ice pelletizer is a piece of equipment specially used to turn liquid carbon dioxide (CO2) into solid carbon dioxide (dry ice) pellets.

        Dry ice pelletizers usually deliver liquid CO2 into the machine through a liquid carbon dioxide supply system. Liquid carbon dioxide undergoes a series of cooling and pressurization processes, causing its temperature and pressure to rise. The pressurized liquid carbon dioxide passes through the nozzle or spray head and enters a relatively low-pressure environment. In this environment, liquid CO2 rapidly relaxes and expands, lowering its temperature and turning into a solid state. Because the temperature drops sharply, liquid CO2 turns into a gaseous state and forms tiny CO2 particles, known as dry ice particles.

        The Dry ice machine can efficiently convert liquid CO2 into a large number of evenly distributed dry ice pellets. The advanced control system can achieve precise control of parameters such as temperature, pressure and particle size to ensure the production of dry ice that meets requirements. Some Dry Ice Granulator have adjustable mechanisms that allow the user to select different sizes of dry ice pellets. There is no need to add any chemicals during the manufacturing process, and the waste material is CO2 gas, so the dry ice pelletizer is considered a relatively environmentally friendly production method. Most Dry Ice Pelletizer Making Machine are equipped with automated operation functions, including automatic adjustment and monitoring systems to improve production efficiency.

3. Dry Ice Block Machine（Dry ice briquetting machine）:

        A dry ice block press is a piece of equipment specifically designed to compress dry ice pellets or pieces into block form.

        Dry ice block presses typically use previously produced dry ice pellets or chips as raw material. These pellets or chips are usually prepared through an overhead dry ice pelletizer or other means. Dry ice raw material is transported to the compression zone and heated to a certain level. The purpose of heating is to cause the dry ice pellets or blocks to begin to soften and melt. After heating, the softened dry ice is placed in a compression zone, where compression machinery or a hydraulic system exerts tremendous pressure to compress the dry ice into blocks. The compressed dry ice blocks pass through the cooling system, where they are quickly cooled and re-solidified to form solid dry ice blocks. The formed dry ice blocks enter the collector through the collection system, and then enter the packaging area through the conveyor system for final packaging.

        Save space: Dry ice in block form is easier to store and transport than in crushed or pellet form, thus saving space.

        Energy savings: Previously produced dry ice pellets or crumbs are used as raw material, reducing the need for additional refrigeration and helping to save energy.

        Automated operation: Most modern dry ice block presses are equipped with automated operation functions, including automatic adjustment and monitoring systems to improve production efficiency.

Application areas:

        Food and pharmaceutical transportation: Dry ice blocks are widely used in cold chain transportation to keep food and pharmaceuticals at low temperatures.

        Laboratory and scientific research: In laboratories and scientific research fields, dry ice blocks are used to prepare low-temperature environments, such as refrigeration reagents.

        Special effects production: Dry ice cubes are often used in film productions and stage performances to create special smoke and cold fog effects.
