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 additionto 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 circuits are also used extensively in other applications and industries including:
