We are specialized in the quick FPC prototype for 1-16L flex PCB boards and also could do flexible circuit PCB board production in affordable price, high quality and quick lead time. Working in Flexible PCB board industry for 10+ years, we now have a 5,000sqm Flex PCB factory, the monthly flex PCB production capacity are more than 15,000sqm. And we have  a team of more than 200 staffs, and more than 20 senior executives have more than ten years of experience in Flex PCB industry. With these experiences and continue to update the equipment,  we maintained the advanced technical capability and high FPC prototype and FPC production capacity in the Flex PCB industry.

 

FPCway is a flex circuit board manufacturer that provides fast flex PCB prototypes, short-runs, and production. We offer flex PCB material and components to build high-quality flexible printed circuit boards.

 

And our FlexIible PCB circuit boards now are highly used in computer, communication network equipment, mobile phone, digital camera, instrumentation, aerospace instrument, biomedical, home appliance and lighting, drone, smart wear, smart home, bluetooth, car, industrial control, robot, tablet, LCD, projection Instrument, car navigation, security and other high-tech fields, etc.

FPC has single sided flexible PCB board, double sided flex circuit PCB, multi-layer Flex PCB and Rigid-flex PCB circuit board. The flex PCB material is polymide FCCL and it has high heat resistance and stable size. Following are the common layer structure and stack up for Flex circuit PCB for your reference. The FPC final thickness could be adjusted flexibly with different thicknesses of PI, adhesive, copper, etc.
