N2 - This article reviews results of our investigations, performed over the period of a decade, on gold plating for electronics applications. Three different topics are covered: (1) development of a new, non-cyanide, soft-gold electroplating bath containing both thiosulfate and sulfite as ligands; (2) evaluation of a known cyanide-based, substrate-catalyzed electroless bath for depositing pure soft gold, and subsequent development of an alternative, non-cyanide, substrate-catalyzed bath; and (3) development of a new process to electroplate amorphous hard-gold alloys for probable future applications as a contact material on nano-scale electronic devices.
