PCB Layers We provide

Single Layer PCB

Single-layer PCBs are used in simple electronic products, such as radios, simple speakers, and other OEM PCB products. View detailed types of printed circuit boards.

2 Layers PCB

2 Layer PCB board is widely used in electronic products, from consumer electronics to industrial products, as a cost-effective advantage in China PCB supplier.

4 Layers PCB

A 4-layer PCB contains four conductive copper layers. The top and bottom layers are the signal layers, and the middle two are the power and ground layers. The power and ground layers can be isolated in the middle to reduce interference.

Multilayer PCB

MultiLayer PCB emerged with the development of science and technology, and electronic products are required to be portable and smaller.

PCB Assembly

PCB Components Purchase

We have a complete material procurement management and control process and can quickly provide customer component quotations. We also accept customers who provide BOM materials to our PCB assembly factory.

SMT Assembly Processing

Our PCB assembly manufacturer has first-class equipment, a perfect quality control system, and rich practical experience, which makes our PCB assembly highly efficient, high quality, and price-advantaged.

Through Hole Assembly

After the PCB assembly is finished, SMT enters the through-hole assembly. Through-hole assembly generally adopts the wave soldering process, and the wave soldering machine is used for welding processing and firm components.

PCB Assembly Testing

We will do a PCB functional test for PCB assembly according to the customer’s requirements.
