Top 10 PCBA Manufacturers and Suppliers in China

PCBA Manufacturers China

China is known for PCB and PCB assembly providers and this article will cover the Top 10 PCBA manufacturers and suppliers in China.

What is PCBA?

The process of soldering various electrical components to the printed circuit board (PCB) and assembling it into a working device is known as PCBA, or Printed Circuit Board Assembly. The components are assembled by inserting and soldering them onto the PCB, which provides an electrical connection between them. This procedure may take on a few forms, but the most common are SMT assembly and PTH assembly.

SMT assembly is an efficient and accurate method for PCB assembly. We will need to print solder paste on the printed circuit first using stencils. Next, electronic parts are placed on the PCB surface by hand or machine. And then, run the PCBs through the reflow oven, this melts the paste and secures the parts onto it.

PHT assembly begins with inserting pins from electronic parts into holes on a circuit board, followed by soldering with tin. This can be achieved using a wave soldering machine that works with a hot solder or manually soldering by hand.
