Abstract
A method for producing conductor coating on dielectric surface may be used in many areas of industry for preparation of dielectric surfaces for selective electroplating. Using this method, conductor coatings are obtained when dielectric items are etched in acidic solutions containing oxidizing agents, then treated in trivalent bismuth compound solution and additionally treated in sulphide solution.
