Abstract
Large area flexible printed circuits (FPCs) are attracting attention as a replacement for automotive wire harness. Reasons include weight and space saving, increased automation of production, improved consistency of performance, and added value through mounting of components on the harness. Automotive multiplexed networks are increasingly important for the functioning of automobiles. The ISO11898 Controller Area Network standard places requirements on the electrical parameters of the physical transmission medium. In this paper fabrication of FPC transmission lines, and subsequent testing for compliance with ISO11898, are described. It is demonstrated that the ISO11898 requirements can be met using a high volume, low cost print-and-etch process.
