Optimized Design of Flat Wiring Systems

Flat wiring like FPC and FFC, already being used for decades in the automotive industry, is now also present inside the wiring harness systems. The advantages of flat wires, for instance weight reduction and easier assembly, can only be achieved, if care is taken to optimize the size of conductors and the interconnection technology. This paper gives an overview of different types of flat wiring technologies and corresponding interconnection technologies. A special focus is put on general flat wiring structure and the dimensioning of conductors.
