Abstract
831,929. Copper-plating baths. DU PONT DE NEMOURS & CO., F. I. May 30, 1958 [June 20, 1957], No. 17404/58. Class 41. A copper-plating bath contains free alkali cyanide together with small amounts of a water-soluble selenate or selenite, a selenide, and also the alkali metal salt of methylene-bis-α- naphthalene sulphonic acid. In an example, to a solution containing copper cyanide, free sodium or potassium cyanide, sodium or potassium hydroxide or carbonate and a little of the naphthalene sulphonic acid compound, there is added (a) 10 to 250 parts by weight per 10<SP>6</SP> of sodium selenate and (b) 0.01 to 0.1 part of a solution of copper selenoide in KCN. Parts are calculated as by weight of selenium metal contained. Plating preferably proceeds with periodic current reversal, and using a moving cathode. Specification 630,165 and U.S.A. Specifications 2,701,234 and 2,770,587 are referred to.
