ABSTRACT:
A method is disclosed for the generation of circuit patterns on a polyimide type of substrate by preconditioning the substrate's surface with a hydrazine/caustic solution, depositing a catalyst on the surface treated polymer, and exposing the polymer with the catalyst thereon to a bath having a metal therein capable of deposition electrolessly on the polymer surface containing catalyst.
