With the advent of the electronic age, printed circuit boards (PCBs) have become a necessity for almost all electronic products. Customizing a PCB is often not the purpose, because they cannot work. In electronic products, the role of the PCB is to bear the electrical connection. Therefore, after the electronics manufacturer has finished manufacturing the PCB, it is often necessary to find a high-quality PCBA (PCB assembly) processing plant for them. Serve.

List of Top PCBA Processing Plants
FS Technology
FS Technology, also known as FS PCBA, is a Chinese PCB assembly company specializing in the PCBA industry. At present, the total number of employees of FS Technology is 500. The company is headquartered in Shenzhen, with three PCB assembly factories and one PCB manufacturing workshop.

The company is good at PCBA processing projects and has served in the PCBA industry for 20 years. They provide automated SMT assembly process, through 7 high-speed SMT assembly lines, your high-volume projects can be completed in the shortest time. It is worth mentioning that FS Technology provides orders from prototype to mass service, and their MOQ is 0, which means you can get the opportunity of prototype PCBA service for free.

SMD chip programming
Moko Technology
Moke Technology's official websiteMoko Technology is a newly established PCB company that provides electronics manufacturers with comprehensive one-stop PCBA projects - from prototyping to high-volume assembly. Compared with the two PCBA processing companies introduced earlier, Moko Technology was established later, but in terms of website browsing experience, it is the best. Although it is not the best in terms of service experience, it can provide a wider range of services. For example, although JLCPCB can serve customers at a lower price, it cannot provide component replacement solutions, while Moko Technology can.

In order to make the project service more complete, Moko Technology employs a large number of experienced engineers and employees. In their PCB blog site, you can see a lot of content related to PCB or PCBA, which also laid a solid foundation for their development. The following are the services provided by Moko technology: https://www.fs-pcba.com/

PCB manufacturing (aluminum substrate, HDI circuit, thick copper circuit board,)

Printed Circuit Board Assembly (SMT, BGA, THT)

Electronics assembly (boxing, cable harnesses, electromechanical assembly, conformal coating)

Agile Circuit
Agile CircuitAgile Circuit is a professional SMT assembly company with mature surface mount technology. It is difficult for electronics manufacturers to find PCBA companies when they are looking for them on the Internet. The company's website is not well promoted, but this does not mean that it is not high quality. When you are browsing their website, you will be overwhelmed by their SMT PCBA manufacturing capabilities.

With the development of the times, DIP assembly was replaced by SMT assembly and gradually began to go downhill again. Agile Circuit is well aware that the trend of the development of the times is irreversible, so they focus on SMT technology and develop it to perfection. Compared with other PCBA manufacturers, Agile Circuit has a more complete SMT assembly process:

Circuit design
Document check
PCB manufacturing
Circuit board cleaning
AOI/manual inspection
Steel mesh manufacturing
Solder paste printing
SPY detection
High temperature reflow soldering
AOI detection
Surface treatment

How to choose the right PCBA service provider
There are a large number of PCBA service providers who claim to be "top-tier" in the market, which is not good for electronics manufacturers. I would think that when the PCBA industry was not yet emerging, most electronics manufacturers faced few choices and could only order from JLC PCBA which is cheap or FS Technology which advocates high-quality services. With the increasing number of PCBA processing factories, although the fierce competition has lowered the service cost of PCBA, it has made it difficult for electronic manufacturers to choose. So, how to choose a PCBA manufacturer?

Cheaper Price
PCBA is a semi-finished electronic product. Most customers looking for services want to use these boards in electronic projects, so PCBA assembly projects are often long-term high volume pcb assembly cooperation orders. Here we have to consider the price issue. Generally speaking, when electronics manufacturers search for PCBA factories on Google, they will find two types of websites - online quotes and offline quotes. 99% of PCBA online quotation sites have lower prices than non-online quotation companies. The reason is simple. PCBA service providers with price advantages hope to use price as a bargaining chip to win the favor of electronics manufacturers, so they hope that customers can get their quotations at the first time. This is not absolute, just like FS Technology, although they do not provide online quotation service, the price of their PCB assembly quotation is almost the same as that of JLCPCB. Some PCB assembly companies that do not provide online quotations want to connect with customers with better services. You need to send your request and design files by email. Although PCBA processing service providers will not quote your project at the first time, their designers will review your files immediately to ensure the accuracy of project design and reduce Create risk.

High-quality service items
Take the current PCBA market in China as an example. You can see many Chinese PCBA suppliers on the Internet, some are powerful big companies, and some are small workshops. With the popularization of PCB assembly technology, even a production workshop with only ten people can complete batch orders in a short time. Not because of their technical proficiency, but because of the omission of many intermediate links.

As we all know, manufacturers need to add a large number of testing processes in PCB manufacturing or assembly projects. These processes ensure the quality of PCBA production and avoid PCB short circuits when customers apply the board to electronic products. At present, I think the companies with the most complete testing services are FS Technology and PCBWAY. These two companies can provide customers with a full range of PCB testing services according to their needs, whether it is manufacturing or assembly.

Board washing is omitted. Come on, it's the wrong way to produce. In the PCBA process, we need to use a lot of chemicals, such as flux. When these acidic/alkaline chemicals remain on the board, an electrochemical reaction will occur as the current flows, resulting in a short circuit. Even if these boards have not been used in a circuit, over time, the surface of the circuit board may corrode, resulting in damage to the circuit. The PCB cleaning process is essential, and both electronics manufacturers and PCBA processing companies need to keep this in mind.
