Abstract:
1. A process for applying conductor tracks to the surface of a plastics molding, encompassing the steps of: a) using, as starting material, a molding with at least one plastics surface, where the molding comprises a structural foam with a solid outer skin and a cellular core, and comprises electrically conductive particles, their amount being such that the core is electrically insulating and the outer skin is electrically conductive, and b) ablating those portions of the solid outer skin with conductive particles therein to expose the electrically insulating cellular core where no conductor tracks are intended to run, with the aid of a selectively ablating process, so as to form a predetermined pattern of electrically non-conducting sections in the cellular core at the treated areas on the plastics surface, thus producing conductor tracks in the solid outer skin at the untreated areas on the surface.
