Flexible Flat Cable (FFC)

DAS and Cell Tower Solutions

Our wiring devices enable highly dense packaging and space-saving electrical transmission, making it possible to produce smaller electronic devices and automotive components with better performance.

  • Flexible flat cables (FFC)
  • Shielded flexible flat cable (FFC) for automotive use

FFCs are flat flexible ribbon-shaped cables with multiple metallic conductors sandwiched between two insulating tapes and are used extensively in consumer electronic products such as digital cameras, audio equipment, flat-screen televisions and office equipment. Shielded flexible flat cable (FFC) for automotive use include high density mounting and fine lead pitch, improved flexibility and handing ability, high heat resistance (110 deg.C) and low connection resistance (20m or less).

Tin/lead alloy solder was formerly used on FFC conductors. RoHS (Restriction of the use of certain Hazardous Substances in electrical and electronic equipment) requirements are driving the development of lead-free FFCs. The drawback of applying lead-free electroplated tin to FFC conductors is that tin whiskers form in the area between the FFC and the connector, and can cause short circuits and arcing in electrical equipment. Hitachi has developed a tin-plated conductor with reduced tin whiskering based on applying a very thin “nano” coating of zinc on the electroplated tin surface.
