FFC, FPC (Flat Flexible) Connectors

Flat Flexible Connectors (FFC) and Flat Printed Circuit (FPC) Connectors are designed to provide efficient, reliable electrical connections between two printed circuit boards (PCBs) or two electrical components. They are commonly used in small, portable devices such as mobile phones, tablets, cameras, and PDAs, as well as in larger products like high-density servers and mainframes. The small size of FFC and FPC connectors makes them ideal for devices where space is at a premium.

Application Field

FFC and FPC connectors are used in a wide variety of applications. They are widely used for interconnecting PCBs, for connecting internal components in handheld devices, and in consumer electronics such as laptop computers, camcorders, and digital cameras. Other applications include electronic test equipment, industrial automation systems, automotive assemblies, communication systems, and medical equipment.

Working Principle

FFC and FPC connectors are typically used to connect two printed circuit boards (PCBs) or two components on the same PCB. The principle of operation involves a mechanical connector and a contact element. The mechanical connector includes a pair of mating connectors, each containing parallel slots for receiving flat flexible ribbon cables (FFCs) or flat printed circuit boards (FPCs). When the two connectors are mated, the ribbon cable or FPC is locked in place by a locking mechanism, providing a reliable connection. The contact element consists of a metal contact that is typically soldered to the PCB, which makes an electrical connection with the FPC or FFC.

FFC and FPC connectors can provide both signal and power connections and are typically available with single or dual row configurations in a variety of sizes. They are typically rated for up to 500V AC, depending on the application. They are also available in a variety of materials, including stainless steel, brass, and plastic.
