What is Flexible PCB?
A Flex Circuit or Flex PCB is a patterned arrangement of printed circuitry and components that utilizes flexible based material with or without flexible coverlay.
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.
Flexible circuit boards other applications
Flexible circuits are also used extensively in other applications and industries including:
- Consumer Electronics
- Medical Industrial
- Military Transportation
