PCBA is a technology for welding all electronic components
When you see these boards, most people can recognize them They are green and made of copper. You can find them in electronic products The assembly process also requires a lot of technical support If you do not master these technologies, PCB may not function smoothly printed circuit board assembly is the process of soldering all electronic components It glues everything to the printed circuit board and consists of many manual and automatic steps Well, let's learn about printed circuit board components
PCBA through-hole technology
You can call it one of the traditional assembly methods. Here, you need the cooperation of various manual and automatic programs.
During this assembly, the following occurs. First, there are electronic components with leads. These come out through the holes on the PCB. The solder mask is stuck on the circuit board. The process is divided into three steps. These are-
1 Component placement,
2 Check and correct,
3 Wave soldering.
The first is a manual process. The engineer places the components in place. In doing so, they need to remember the design file of the circuit board. This will help them design according to customer needs.
The placement of components ensures the high quality of products to a certain extent. For production, the manufacturer follows some operating standards and regulations.
Circuit board

For example, the engineer must constantly check to ensure that the polarity is clarified. They need to see the direction of the component relative to the environment component. The finished component placement needs to meet the corresponding standards. Some people must wear an anti-static wrist strap. They must do this when handling static sensitive components. This is especially true, for example, when they deal with integrated circuits.
The second step is to check and rectify. After placing the components, the circuit board is now placed on the matching frame for transportation. The Board of Directors needs to investigate. All components must be checked for safety. Ensure the accuracy of the arrangements. If there are any problems, it is essential to correct them now. This is easy because this stage is before welding in the assembly process.
The last process is wave soldering. This is the third process after the through-hole components are welded to the circuit board. Here, you put the circuit board into a more liquid solder mixture. Occurs at a high temperature of about 500 degrees Fahrenheit. At the end of this process, the components will be securely attached.
Surface Mount Technology method
In this PCB Assembly process, electronic components are tiny and sensitive. They are like diodes and resistors. The equipment and welding materials here are different.
The process here is different from the above. In some respects, it even stands out. You can achieve higher manufacturing efficiency here, which is one of the reasons many manufacturers adopt this method. Everything happens in selection and location, solder paste printing and reflow soldering.
The process consists of three steps. We will discuss these three aspects below.
The first step is solder paste printing. Here, paste is applied to the code by pasting the printer. To ensure the accuracy of the installation, the manufacturer uses a template or wire mesh.
How do you determine the influence of solder paste printing quality on welding quality? The manufacturer wants to check it. The solder paste inspector is responsible for this work. They begin after the printing process. Through this inspection, you can meet other strict regulations. If there is any defect, the manufacturer can reprint and clean it. Only in this way can the second printing start.
The second step is to install the components. When the circuit board is removed from the printer, it will enter the microphone and be placed. The machine is here. You can install integrated circuits or components on the corresponding pads. You need to consider the tension of the paste. You can install the ingredients on the circuit board through the component reel inside the machine. It helps the parts stick firmly to the circuit board.
The last step is what we call reflow soldering. Here, you put the components on the circuit board through a long furnace. Again, you need a temperature similar to that above. It helps to liquefy solder. Then, all the elements are firmly bound to the board.
Hybrid technology
Today, electronic products become more integrated and complex. In addition, the size of the circuit board is getting smaller and smaller. Strangely, a circuit board contains only one type of component.
Most circuit boards have through holes and surface mount components. It requires cooperation between two technologies. Yes, the welding process is very complicated. You don't want to affect it with a lot of elements. You need to better prioritize the two technologies.
Familiar with PCB assembly file format
When choosing a free board, make sure your manufacturer is experienced. You need them to be able to handle the format you plan to use. This is a critical step because some manufacturers may not be able to trade all file formats. The two most popular options are CAD and Gerber.
File format is a key step in PCB design. You must ensure that the manufacturer you choose has good experience with the forms you plan to use.
Communicate with PCB component supplier
Contact the PCB component supplier during the design phase. Don't wait until the end, because it can open more design options for you. You will understand the basic suggestions on the map and have a deeper understanding of the industry. You will learn about new processes and technologies. They let you know the latest models, methods and industry trends
Use all available tools to make the final product
Your assembly program can provide you with tools to help you get the most effective final product. Know what you need. Communicate with the manufacturer in the design stage. The latest technology can improve efficiency. See how to make the final product better. Be cautious when dealing with overseas suppliers
Many people began to choose foreign suppliers. On the one hand, they offer goods at affordable prices. But this process is accompanied by many risks.
Overseas suppliers sometimes prefer to use low-quality parts. These are not the correct standards. In turn, it will affect you in the long run. There are also some production delays that will affect your schedule. You need a reliable overseas supplier.
Don't rely on a single supplier
Don't expect new suppliers. Or, only one supplier can meet all your needs. There is always a backup plan. You want to ensure a perfect design with maximum care. In addition, do not attempt to include parts that are not available on the market.
printed circuit board assemblies always name and mark parts
You should always try to mention the names and numbers of all components included in the package. It helps to reduce the scope of any errors. In addition, labeling is a good practice. You don't want to mix things up. It will take a lot of time to solve this problem in the future.
Printed Circuit board assembly makes labels easy to read
Make sure your number and label sections are easy to understand and read. For example, if there are two parts, mark them as part 1 and part 2. If the names are similar, they are represented by different pipes. In this way, you have no room for mistakes.
Pay close attention to manufacturing test design
Manufacturing test design helps to reduce related costs. It makes trading more comfortable. It also identifies and resolves potential problems to ensure a smooth manufacturing process.
Check each trade
Learn what you want from a circuit board to get a well-designed printed circuit board component. The best way is to talk to customers. They can give you tips on how to improve your design to meet all your needs.
PCB assembly test before ordering
When you place a large order, many places have large discounts But unless you are sure of the quality they provide, you should not be taken in Before ordering in bulk, please try the final circuit board product to ensure it is in good condition You can also hire the services of different PCB assemblers to compare and make a final decision
