Abstract
Manufacturing process for manufacturing printed circuit boards from an extruded polymer, comprising the steps:-preparing an electro-conductive plate () and form embossments () by means of selective engraving on a first side (), corresponding to future tracks and depressions () corresponding to future inter-track areas;-applying a dielectric substrate material, in a pasty or semi-pasty state, according to a first sheet () obtained by extrusion of a thermal-plastic material, arranging it on said first side (), covering said embossments () and filling said depressions (), and subjecting the first sheet () and plate () assembly to a predetermined pressure so that the dielectric substrate material completely fills said depressions and encloses said embossments (), and-on the hardened dielectric substrate, carrying out a second selective engraving on a side opposite the first side (), removing the material corresponding to said future inter-track areas.
