  • Patent number: 4870751
    Abstract: A method of manufacturing printed circuit boards. An environmentally safe method for manufactured printed circuit boards using additive technology provides a simple and exact transfer of conductor patterns. The novel method provides a selective ablation of a nucleation, B, applied to a substrate either by itself or together with a thin base layer, G, applied by chemical metal deposition. This ablation is done by electromagnetic radiation preferably with an excimer laser in those regions of the substrate that do not correspond to the conductor tracks and/or interlayer connections or through-connections to be formed later. Conductor material is subsequently built up by chemical and/or galvanic metal deposition.
