Abstract
A method of forming adherent metallized coatings on a substrate which is useful for the manufacture of printed circuit boards as well as other metal coated articles involves providing the substrate with a rubber-modified epoxy surface or coating, sputter etching at least 50 A. from the surface followed by vacuum depositing an adherent thin metal film of Cr, Ni, Ni-V alloy, Pt, Pd or Ti onto the substrate. Another metal layer is then provided over the adherent thin film.
