Keypad Membrane Single-sided flexible PCBs FPC Polyimide PCB Board
This is a type of flexible printed circuit for the application of keypad membrane. It’s a single layer FPC at 0.1mm thick. The base laminate is from ITEQ, It’s fabricated per IPC 6012 Class 2 using supplied Gerber data. Polyimide stiffner is applied on the inserting head.
Flexible circuits are also used extensively in other applications and industries including:
Communications
Consumer Electronics
Automotive
Medical
Industrial
Aerospace
Military
Transportation
