Flexible PCB (FPC) Fabrication Capability
We mainly produce high-precision single-sided, double-sided (double-sided FPC LED lamp strip), multi-layer ultra-thin (such as high-precision printer data transmission flexible wiring), ultra-long flexible circuit board (such as ultra-long industrial control antenna) and so on. FPC is widely used in UAV, intelligent wearable devices, intelligent home, BlueTooth, automobile, aviation instrument, industrial control, medical equipment, robot, mobile phone, tablet computer, LCD, projector, on-board navigation, digital camera, security, printer and other terminal technology products. Select high-quality flexible circuit board materials, advanced flexible circuit board manufacturing process, and capability, ensure product quality, reasonable price.
