FFC, FPC (Flat Flexible) Connectors

Flat flexible cable (FFC) and flat printed circuit (FPC) connectors are an essential component in many devices and products. They are compact connectors designed for high speed data transmission. They offer a reliable electrical connection between a printed circuit board and a connector. The main types of FFC/FPC connectors are: board to board, board to cable, and cable to cable.

Application Field

The application areas for FFCs and FPCs are extensive, but some of the most common uses include computer and laptop hardware, smartphones, electronic appliances, industrial machinery, medical equipment, home appliances, automobiles, and many more.

The slim design of FFC/FPC connectors makes them especially useful for fitting into tight spaces. For example, they are often used for data transmission between the main circuit board and auxiliary components of laptop and mobile phones, as their small size makes them ideal for fitting in these limited spaces.

Working Principle

FFC/FPC connectors utilize electrical contact pins in conjunction with the flex cable to provide a secure electrical connection. The flex cable contains multiple conductive tracks, each of which is connected to a separate pin. When the FFC/FPC connector is inserted into the mating connector, the contact pins come into contact with the receptacles in the mating connector, forming an electrical connection.

The FFC/FPC connector is available in both standard and custom sizes, depending on the application needs. The flex cable can be single-sided, double-sided, or multi-layers, and is often made of special materials to increase its strength and flexibility. The number of pins and their positions can vary depending on the requirements of the application.

The number of mating cycles for an FFC/FPC connector varies according to its type and application. Some connectors are designed to withstand thousands of mating cycles, while others are rated for only a few hundred cycles. The lifespan of the connector is also greatly affected by the environment in which it is used.

Conclusion

FFC/FPC connectors are a versatile and reliable solution for a variety of applications. Their small size and high versatility make them ideal for connecting components in tight spaces. They can be used in a wide range of different applications and can support thousands of mating cycles. By understanding the application field and working principle of FFC/FPC connectors, designers can make the best possible decision for their application.
