Little knowledge - PCB Circuit Board

A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate.

Components (e.g. capacitors, resistors or active devices) are generally soldered on the PCB. Advanced PCBs may contain components embedded in the substrate.

There are three kinds of PCB, including single sided pcb (one copper layer), double sided pcb (two copper layers)and multi-layer pcb (outer and inner layers). Conductors on different layers are connected with vias. Multilayer PCBs allow for much higher component density.

Established in 1999, we own 3 modern factories in China.

Guangdong province - Shenzhen PCB Factory and Dongguan PCB Factory.

The total production capacity is 290,000 sqm/month.

Our main product is high precision multilayer circuit board. 

Also we are experienced in PCBA.

Advanced equipment and professional technical support provide quality product.

Certifications obtained include :

We sincerely pursue win-win business with customer all the time!
