Abstract

A low-cost electrical conductor is prepared by applying a mixture of a metallic powder and a polymer on a substrate, curing the polymer, effecting an augmentation replacement reaction to replace some of the metallic powder with a more noble metal in such a way that the total volume of deposited metal at the surface exceeds that of the original metal powder replaced, and thereafter applying a dielectric material to selected areas of the conductor thus formed. Imperfections such as pin holes and screen marks can be eliminated by heating the dielectric material to cause a degree of flow. Multiple layer interconnected conductors can be prepared by reapplying the mixture of metallic powder and polymer such that a portion thereof contacts the first prepared conductor, curing the polymer and effecting an augmentation replacement reaction with a metal which is more noble than the powder metal and the replacement metal of the first conductor.
