Abstract
It consists of making a first engraving over a first face of a panel of electro-conducting material to form some reliefs and depressions corresponding to future tracks and intermediate tracks; subjecting said first face to a black oxide treatment (); applying a layer of an adhesive material over said first face previously engraved and treated with black oxide; applying by injection moulding a dielectric material () over said previously engraved first face, treated and with the adhesive applied, covering said reliefs and filling said depressions; and carrying out a second selective engraving over a second face, opposite to the first one, of the mentioned panel to eliminate the material thereof corresponding to said future intermediate tracks, so that some finished tracks () remain insulated from each other, partially embedded on a face of said dielectric material () and separated by intermediate tracks ().
