What is Flexible PCB?
These flexible electronic assemblies may be fabricated using the same components used for rigid printed circuit boards, but allowing the board to conform to a desired shape (flex) during its application.
Flexible PCB / FPCB Applications
FPCBs are used widely in everyday
technology and electronics in addition
to high-end, complex completed components.
Two of the most prominent examples
of flexible circuit usage is in modern
portable electronics, devices,
hard disk drives and desktop printers.
- Consumer Electronics
- Medical Industrial
- Military Transportation
