Process for the manufacture of three dimensional plastic parts having integrated conductive tracks

摘要

Plastic parts produced from thermoplastic moulding materials by injection moulding are subjected to the following steps: - Plasma etching in an oxidising atmosphere; - Plasma treatment in a noble-gas atmosphere, in particular argon atmosphere; - Metallisation by sputtering in a noble-gas atmosphere, especially argon atmosphere. Conductive tracks can be formed on the plastic parts metallised in this way by the subtractive technique or semi-additive technique. An adhesion of the metallisation, determined using the peeling test, of at least 1 N/mm is achieved. The wet chemical pretreatment and chemical copper plating of the plastic parts which were hitherto required are obviated.
