Abstract
The present invention relates to the etching, activation and deposition of a first metal or metal alloy layer onto non-conductive polymers. The non-conductive polymer is etched with an aqueous solution comprising 0.75 to 3.6 g/l permanganate ions in 60 to 80 vol.-% sulfuric acid, activating with a solution comprising a noble metal and depositing a first metal or metal alloy by immersion-type or electroless (autocatalytic) plating. The first metal or metal alloy layer obtained has a high adhesion on the non-conductive polymer and serves as a plating base for electroplating further metal and/or metal alloy layer(s) thereon.
