Flexible Flat Cable (FFC) For Automotive

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)

FFCs are flat flexible ribbon-shaped cables with multiple metallic conductors sandwiched between two insulating tapes. They 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 application use include high density mounting and fine lead pitch, improved flexibility and handing ability, high heat resistance PVC (105°C / 221°F) and low connection resistance.

Tin / lead alloy solder was formerly used on FFC conductors, but ongoing Restriction of the use of certain Hazardous Substances (RoHS) in electrical and electronic equipment requirements have led to 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. This can cause short circuits and arcing in electrical equipment. To address this, HCA has developed a tin-plated conductor with reduced tin whiskering based on applying a very thin “nano” coating of zinc on the electroplated tin.

Benefits of FFCs:

  • Reduced mounting costs. Since both ends of the terminals are machined, terminal machining preprocessing can be eliminated.
  • Excellent flexibility. The flat copper conductor encourages the CU-Joiner flexibility.
  • Custom designs are available to match the mounting method, the type and number of wires, pitch between wires, terminal length and insulation length.
  • Thirteen UL approved types available.
