Flexible Printed Circuits (FPCs) have been used extensively in instrument clusters and more recently in headliners of same vehicles. Interest in large area FPCs as a replacement für traditional wiring harnesses has been propelled by the potential benefits, which include weight and space savings, ease of assembly into the vehicle, intelligence through direct mounting of electronic components, and creative design opportunities. This paper describes the development of a specification for flexible copper-clad dielectric materials to be used in the construction of a large FPC intended to replace an instrument panel wiring harness. The specification is based on standard printed circuit industry test for flexible copper-clad materials to measure mechanical, electrical and chemical properties relevant to automotive applications. A test program has been instituted to identify acceptability criteria, including accelerated ageing test parameters. An initial assessment of candidate materials has been discussed. It is expected thaI the criteria identified by the test program can be modified further by comparison between lab and field data.
