Detail Information

Description :

FPC (also called flexible PCB) has plenty of advantages such as light, thin, flexible and anti-interference, which can conform to your high standard requirement. In addition to the basic single sided type, we offer double sided FPC, and multi-layers type.
FPC can be applied to wearable device, 3C products, headlight, timer, LCD, etc.
