First of all,let's learn about: the classification of circuit boards
According to the number of layers, circuit boards are divided into three major categories: single side, double side, and multi-layer circuit boards.
1. Single side PCB is the most basic PCB. Parts are concentrated on one side, and wires are concentrated on the other side. Because wires only appear on one side, this PCB is called a single-sided circuit board. Single layer PCB are usually easy to manufacture and low in cost, but the disadvantage is that they cannot be applied to too complicated products.
2. Double side PCB are an extension of single side PCB. When single side wiring cannot meet the needs of electronic products, double side PCB must be used. There are copper clad and traces on both sides, and the lines between the two layers can be conducted through via holes to form the required network connection.
3. Multi-layer board refers to a printed board that has more than two layers of conductive pattern layers and the insulating material between them are laminated at intervals, and the conductive patterns are interconnected as required. Multilayer circuit board is the product of the development of electronic information technology in the direction of high speed, multi-function, large capacity, small volume, thinner and lighter weight.
About PCB Assembly
After the Bare PCB is made according to the requirements, if it needs to realize its function, it needs to be assembled, which is often said in the industry: SMT, soldering.
SMT refers to surface mount technology, which is currently the most popular technology and process in the electronic assembly industry. Simply put, the process of assembling components onto PCB is called the SMT process.
Soldering specifically refers to through-hole components that cannot be processed by the SMT process, and are only soldered after the SMT process. In PCBA processing, some components are not suitable for SMT processing and can only be soldered after SMT. It can be manually soldered with a soldering iron, or sprayed with rosin perfume and soaked by hand, or directly through the wave soldering (the first step of wave soldering is to automatically spray flux to the soldering surface of the board).
For how wave soldering works, please see the video link below:
So, why should you choose a Chinese PCBA manufacturer?
First of all, China has strong production capacity and complete supporting facilities.
Since the 1990s, China's PCBA processing industry has developed for many years, has a strong technical foundation, and also has relatively complete infrastructure and supporting facilities. China's small and medium-sized PCBA processing enterprise model can well adapt to the needs of the international market, which is a huge advantage.
Second, competitive prices and government technical policy support
As a country with a large population, China has relatively low labor costs and significantly lower production costs than European and American countries, while maintaining much better quality and service than other Southeast Asian countries such as India and Vietnam.
In addition, the Chinese government actively supports and promotes the PCB business. Since 2019, the National Development and Reform Commission of China has listed "manufacturing of high-density printed circuit boards, flexible circuit boards, high-frequency microwave printed circuit boards, high-speed communication circuit boards, and high-performance copper-clad laminates" as encouraged industries.
Third, constructive design and production suggestions can be put forward.
After receiving the cooperation contract, Chinese PCBA manufacturers can put forward constructive suggestions on PCB design, material selection, component selection, process flow, etc., to improve efficiency and reduce costs for customers.
With these factors in mind, it is indeed a wise decision to consider Chinese PCB manufacturers when looking for reliable and cost-effective electronics manufacturing solutions.
Now let's take a look：Top10 PCBA manufacturers in China

Foxconn invested in mainland China in 1988. Currently, it has more than 40 industrial parks in mainland China. At its peak, it had millions of employees. Its product range covers consumer electronics products, cloud network products, computer terminal products, components and other four major areas. It is the world's largest Electronic technology smart manufacturing service provider. In 2022, the group's revenue will be about 1.49 trillion RMB, an increase of about 10% over the previous year; the group's total imports will be about 540 billion RMB, accounting for 3.0% of mainland China's total imports; total exports will be about 849 billion RMB, accounting for 3.0% of mainland China's total imports; 3.5% of total exports. In 2022, it will rank 20th in the Fortune Global 500.
JLCPCB，It cannot be ignored in China. You must have heard of JLCPCB, even if we didn’t mention it.
JLC established in 2006, their biggest advantage is its online PCB design and ordering system, their prices are among the lowest in the industry. Therefore, their have a wider range of customers, which means that a sales or engineer needs to connect with dozens or even hundreds of customers. And they do 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. So, although SYS Technology has a higher price, it can provide one-to-one dedicated service, and greater flexibility, many electronics manufacturers still avoid JLC and choose SYS Technology due to its inflexibility.
Founded in Taiwan China in 1973, and set up a factory in Utah, USA in 1989. Due to the rise of China's economic power, it has become a key area for the production layout of global manufacturers. After the government opened up investment in the mainland, in order to obtain the advantages of manufacturing costs, meet customer requirements and potential markets, etc., in 1996. Set up a production base in Huizhou, Mainland China, to strengthen COMPEQ's global presence. In 2004, COMPEQ Precision Circuit Board (Huizhou) Co., Ltd. and COMPEQ Computer (Suzhou) Co., Ltd. were respectively established to provide flexible boards and a small number of parts assembly services required by customers to meet customers' multi-faceted needs.
Why put the three of them together? Because: they are different brands of the same company.
They rely on new thinking in the internet industry and are committed to creating a benchmark for “smart manufacturing.” They have transformed from a traditional factory to a modern digital smart manufacturing platform, 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.
