Flexible PCB Flexible Circuit Fabrication A Flex Printed Circuit or Flex PCB is a basically a flexible Base material, with a patterned arrangement of printed circuitry on Copper and components, with or without flexible overlay. 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 circuits are also used extensively in other applications and industries including:  Communications  Consumer Electronics  Automotive  Medical  Industrial  Aerospace  Military  Transportation In Automotive, Transportation they are extensively used due to their improved resistance to vibrations and movement.
