FFC, FPC Connectors

A FFC, or flat flexible connector (FPC), is a type of electrical connector used in a wide range of applications. It is also frequently referred to as an F-connector, flex circuit connector, finger-joint connector or ribbon cable connector. FPC connectors are electrical connectors composed of individual conductors that are placed on a flat flexible material that can be bent and wound around more complex jumps or shapes, without sacrificing electrical contact.

FFC connectors are typically used in today\'s consumer electronics devices like consumer television, DVD players, video game consoles, digital cameras, portable media players, mobile phones and other small devices. They offer advantages of space, cost and disconnect-ability over other types of connectors. FPCs can be made up of a variety of materials including polyamide, polyimide, polyester, glass reinforced plastic and polyphenylene sulfone. The choice of material and number of contacts will depend upon the application.

FFC connectors are generally manufactured with a snap-in retention system, keyed connectors, and independently molded connectors. This allows for connection or disconnection of conductors without the use of tools. In general, these connectors are designed to have low contact resistance and high retention force. FFC/FPC connectors provide secure, positive connections with optimal electrical performance.

The typical application of FFCs includes traditional computer, mobile phone, media player and consumer electronics applications as well as applications in industrial, medical and automotive markets. These connectors are frequently used in applications such as LCDs, ethernet cables, USB cables, PCI express cables, ribbon cables, audio cables, coaxial cables, automotive harnesses, and many other applications. Their small size and low profile makes them perfect for use in tight spaces and areas with limited access.

The working principle of FFC connectors is quite simple. The electrical current is transmitted through a wire which is in contact with the two parts of the connector. A small portion of the current flows from one part of the connector to the other and forms a connection between the two. This connection is known as a conduction path. The conduction path will depend on the specific design of the FFC connector, as well as the type of material used to insulate the connection.

FFC connectors are highly reliable, cost-effective solutions which are designed to make electrical connections between components in a variety of applications. They are suitable for use in a range of environmental conditions, including hot, cold and humidity. Their small size and low cost make them a popular choice for many applications.
