Flex PCB, Flexible Printed Circuit Boards
What is Flex Printed Circuit Boards?
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 Printed Circuits OverviewFlexible printed circuits were originally designed as a replacement for traditional wire harnesses. From early applications during World War II, to the present, growth and proliferation for flex circuits and flexible printed circuit boards continues exponentially. A flexible circuit in its purest form is a vast array of conductors bonded to a thin dielectric film. Any one of the following descriptions refers to flexible printed circuitry (FPC):
- Flex Circuits
- Flexible Printed Circuit Boards
- Flexible PCBs
As a connective device, the primary benefits of flexible circuits compared to traditional cabling and rigid boards include:
- Reduced wiring errors
- Elimination of mechanical connectors
- Unparalleled design flexibility
- Higher circuit density
- More robust operating temperature range
- Stronger signal quality
- Improved reliability and impedance control
- Size and weight reduction
Flexible PCB / Flex Printed Circuit Board 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:
