FFC and FPC Connectors


FCI and Digi-Key offer an array of Flat Flex Series connectors


FFC and FPC Connectors One of the reasons flex circuits and connectors have become an important part of the connector world is their unique ability to fill the role of problem solver. Flex circuits can be used to bridge the gap between two boards that may not be positioned in a way that allows connection with a traditional two piece coplanar or mezzanine interconnect solution. Flex cables can be used to transmit signal as well as small amounts of power from one board to another. Another popular use for flex circuitry is as an interconnect for backlighting applications. Perhaps, the most common use of a flex connection is to terminate an LCD or other display to a printed circuit board.

FFCs (flat flexible cables) from FCI are the most robust flat metal conductors laminated between two dielectric films, typically polyester or polyimide and can provide high current carrying capability. FPC (flexible printed circuit) cables are chemically etched copper conductors on a base film of Mylar or similar material that are lighter in weight and utilize stiffener for termination into the board connector.
