Flat Flexible Connectors (FFC, FPC)

Flat Flexible Connectors (FFC) are a type of interconnect used to bridge electronic circuits. FFC are a type of FPC (Flat-Flexible Cable) which is specifically designed to provide electrical connections between printed circuit boards (PCB). FFC can also be used in high-speed communication applications.FFC use a flexible cabling structure that enables it to be used in various applications such as data communication and power transfer. This flexibility has resulted in FFC being a popular choice for many applications. This article will provide an overview of the application field and working principle of FFC.

Application field of FFC

FFC is widely used in various areas such as consumer electronics, automotive, communication systems, medical devices, aviation and military applications. In consumer electronics, FFC is often used for connecting displays, touchscreens, remote controls and other devices. It is also used in automotive and avionic applications for data communication and power transfer.In addition to these application fields, FFC can also be used in communication systems for connecting data, audio and video signals. This includes Ethernet, Wi-Fi, Bluetooth and other wireless communication protocols. In military applications, FFC is used for data communication between electronic systems.

Working principle of FFC

FFC uses a flat flexible cable assembly comprised of two sides with conductive contact pads which are separated by a layer of insulation material. The contact pads on the two sides create the electrical circuit when pressed together. This contact interface is commonly referred to as a ZIF (Zero Insertion Force) connector.When the FFC is inserted into the socket, the contact pads on the FFC will be forced apart. The contact pins from the socket will then be inserted into the contact pads from the FFC. This creates electrical connection between the contact pins and contact pads from the FFC.The conductive contact pads are usually made from copper or gold and use gold contact pins in the socket. This ensures a reliable electrical connection which can withstand vibration and temperature changes.The FFC is often secured to the socket using a clip or locking mechanism. This ensures that the FFC is firmly connected to the socket and is not subject to vibrations or mechanical damage.

Conclusion

FFC is an effective method for connecting and transferring data and power between various electronic systems. It is widely used in consumer electronics, automotive, communication systems, medical devices, and military applications. FFC uses a flexible cabling structure and conductive contact pads that are separated by an insulation layer. The contact pins from the socket will be forced into the contact pads from the FFC when the FFC is inserted into the socket. This creates an electrical connection between the two systems. FFC is often secured to the socket using a locking mechanism to ensure it remains firmly connected and isn’t subject to vibrations or mechanical damage.
