- achieve or preferably exceed the same high plating rates as acid gold cyanide baths (in an analogous technology for Trivalent Chromium plating, we have achieved up to 5x higher plating/throughput rates as compared to conventional hexavalent chromium plating);
- improve the current efficiency compared to the acid gold cyanide bath;
- reduce the grain size, by favoring grain nucleation over grain growth, thereby increasing hardness and wear resistance and eliminating the need for nickel and cobalt;
- improve bath life by operating in an acidic pH range; and
- run in a pH range which is compatible with photoresists used in printed circuit board fabrication.
Supplemental Keywords:gold, gold coatings, nickel, cobalt, manufacturing, non-toxic elements, cyanide, sulfite
