List of PCB & PCBA Manufacturers in China
With the continuous development of technology, the electronics manufacturing industry has become a vital component of the global manufacturing industry. Electronics manufacturers face increasing challenges and opportunities and must adjust and update their business models to meet market demands. Furthermore, selecting suitable PCBA manufacturers is one of the top priorities for electronics manufacturers.
As a critical component of modern electronic products, printed circuit boards directly impact the performance, reliability, and safety of electronic equipment. Therefore, it is necessary to carefully consider finding the PCB manufacturer, even if it takes time. Fortunately, this article provides a list of the most renowned PCB & PCBA manufacturers in China.
How to find the right PCB assembly company
With the expansion of the 5G industry, China’s printed circuit market has been rapidly growing. Professional organizations predict that China’s PCBA exports will make up over 50% of the global market in 2021. However, due to a lack of information, it can be challenging for other countries to identify excellent PCB manufacturers in China, which can create inconvenience for electronics manufacturers.
In reality, the data may seem impressive, but there are underlying issues. According to reports, in 2019, the Chinese government seized hundreds of small PCB workshops in Huizhou. Without exception, these seized manufacturers were non-compliant and deceiving consumers in the Internet of Things sector. Rest assured that the manufacturers listed below have been thoroughly inspected and meet the required standards.

When you look at the manufacturer list, you may be thinking, “Are you kidding me? I have never seen this company before.” However, it is not true. Although most people have probably never heard of JBDPCB, you must know “PCBWAY” and “PCBGOGO.” In fact, they are different brands of the same company.
Established in 2013, JBDPCB relies on new thinking in the internet industry and is committed to creating a benchmark for “smart manufacturing.” It has transformed from a traditional factory to a modern digital smart manufacturing platform. JBDPCB focuses on the field of electronic circuits and continuously expands its range of services. The products cover PCB R&D and design, circuit board batch/proofing services, SMT PCBA, component procurement, and other related fields. JBDPCB is a reliable turnkey PCBA company that you can count on.
Representative of China's PCB Industry - JLCPCB
In the list of Chinese PCB manufacturers, you must have heard of JLCPCB, even if we didn’t mention it. This is because it is the most powerful and well-known company in China’s PCBA industry.
Established in 2006, JLCPCB is headquartered in Shenzhen, China, and provides EMS PCBA services. This means that if you choose JLC as your service provider, you can enjoy a full range of services from design, manufacturing, and PCB assembly to logistics.
Compared to other manufacturers on the list, JLC’s biggest advantage is its self-development capabilities and online PCB design and ordering system. While offering numerous services and conveniences, their prices are among the lowest in the industry.
However, even though JLC’s prices are lower than those of FS Technology, many electronics manufacturers still avoid JLC and choose FS Technology due to its inflexibility.
- JLC has a wider range of customers, which means that a sales or engineer needs to connect with dozens or even hundreds of customers. However, although FS Technology has a higher price, it can provide one-to-one dedicated service.
- JLC does not provide a wide range of component replacement services. Sometimes when you want to obtain components from a designated component supplier, JLC may not be able to meet your requirements.
- Currently, many electronics manufacturers collaborate with PCBA factories in mainland China through service providers in Hong Kong as intermediaries because Hong Kong service providers can organize the entire project in an orderly manner. Additionally, when choosing a manufacturer that focuses on services, many links can be omitted.
