Flat Flex, Ribbon Jumper Cables

Flat Flex, Ribbon Jumper Cables, also known as FFC cables, are flexible electrical connectors with contacts on both sides of the shielded structure. They are designed to be used on circuit boards in electronic applications, from medical devices to aircraft electronic systems, where compact size and flexibility around the circuit are required. The design of the FFC cable backplane allows for long distances in bundle and flexibility while providing a high density of contacts.

Application Field for Flat Flex, Ribbon Jumper Cables

FFC cables are ideal for highly populated, short distance, front-to-back, signal application services in small consumer electronic devices such as tuners, disk drives, and DVD players. They can also be used to connect backplanes in high-speed networking switches, as well as in other IC packages, such as memory and storage devices. Economy and compactness of design make FFC cables a widely used device for mobile phone production. Moreover, in military and aerospace applications, FFC cables are used due to their flexibility and reliability in extreme temperature and hazardous environments.

Working Principle

Flat Flex, Ribbon Jumper Cables are composed of two main components: Flat Flex Cables (FFC) and ribbon jumpers. FFC cables are ribbon-style cables composed of a plurality of conductors formed in parallel rows on a fragmentarily insulated base. Conductors are usually made of copper to provide conductivity, which is insulated by a thin substrate. The top surface of the cables is usually finished with a protective film. The protective film helps protect the conductors from mechanical wear and tear, as well as providing reliable contact between the contacts and connectors.

Ribbon jumpers are typically constructed of a wire formed into contact areas which mate with the FFC contacts. Ribbon jumpers can be made of copper, aluminum, or other conductive material. Each end of the ribbon jumper is attached to a desired contact area. Information, in the form of electrical signals, can then be communicated from the FFC contacts to ribbon contacts on the other end of the ribbon jumper.

Conclusion

The FFC cable design offers a highly reliable, cost effective, and compact solution for high-density front-backplane applications. As a result, Flat Flex, Ribbon Jumper Cables have widely become the preferred choice for reliable and steady transmission services both in military and commercial applications. However, it is still important to take into consideration the application specifications when choosing a design, as FFC cables can be limited to short distance applications.
