Abstract
An electroless or autocatalytic gold plating bath includes, as the gold ingredient, an admixture of (a) a water soluble trivalent gold component selected from an alkali metal auricyanide, an alkali metal aurihydroxide, and an alkali metal aurate and (b) a water-soluble monovalent gold component such as an alkali metal aurocyanide. The bath contains an amino borane, alkali metal borohydride, alkali metal cyanoborohydride, hydrazine, or hyposulphite as the reducing agent an alkaline agent such as an alkali metal hydroxide and an alkaline buffering agent. The method of using such an electroless or autocatalytic plating bath for depositing gold on metallic substrates such as gold, copper, copper alloys, electroless copper, electroless nickel, nickel, nickel alloys, etc. and on a nonmetallic substrate is also described.
