Abstract (en)
[origin: WO9910926A1] According to the invention, teeth (Z) are incorporated into a three-dimensional, injection-moulded substrate (S) during the injection moulding process, said teeth being located in the outer edge area and/or in the area of a recess. A metallic coating (M) is then applied to the substrate (S). Extremely finely structured electrically conductive cross connections are produced when said metal coating (M) is removed in the area of the teeth (Z), especially after the teeth (Z) have been ground down or cut off.
