PCB Electronic Assembly

PCB Electronic Assembly, namely PCBA (Printed Circuit Board Assembly), refers to the complete processing service of mounting, soldering and testing various electronic components on bare PCB boards. Different from empty PCB bare boards, our finished PCBA products are functional circuit modules that have completed component welding, circuit conduction testing and quality inspection, which can be directly assembled into terminal electronic equipment to realize signal transmission, data processing, energy conversion and other core functions .

We provide one-stop customized PCB electronic assembly solutions, covering consumer electronics, industrial control, automotive electronics, medical equipment, smart home, communication equipment and other fields. Support small-batch prototype proofing and large-scale mass production, with high precision, high stability and high cost performance.

 

We adopt dual mature processes of SMT and THT, and support mixed assembly to meet the differentiated needs of different products:

1. SMT Surface Mount Technology

Adopt fully automated stencil printing, high-speed precision placement and reflow soldering process. It is suitable for miniature, high-density and high-precision components, including 01005/0201 ultra-small resistors and capacitors, BGA, QFN, CSP, LGA fine-pitch chips and various SMD surface mount devices . The process features high component density, compact board size, fast production efficiency, good high-frequency electrical performance, and is suitable for lightweight and miniaturized electronic products.

2. THT Through-Hole Technology

For high-power, high-stability and special pin components that are not suitable for SMT mounting, we adopt manual + wave soldering through-hole assembly process. It is applicable to plug-in resistors, capacitors, inductors, connectors, power tubes and other components, with strong mechanical stress resistance and high connection firmness, meeting the high-reliability requirements of industrial and high-power equipment .

3. Advanced Custom Processes

Support mixed SMT&THT assembly, conformal coating waterproof and anti-corrosion treatment, gold finger edge connector processing, high-voltage power board assembly, fine-pitch chip welding and other special processes to meet complex product design requirements .
