Abstract
A thin film electrical cable 20 is disclosed having a polyimide substrate 46, a layer of titanium 48 on a lower side 50 of the substrate 46, and a plurality of gold conductors 52 on the titanium 48. The thin layers of titanium and gold are preferably sequentially deposited on a clean polyimide film by sputtering. Additional gold is electroplated and separate conductors are delineated. The use of organic adhesive materials to attach the conductors 52 to the substrate 46 is avoided.
