Complex Fluorides for the Deposition of Tin and Tin Alloys

Abstract

Further work on the deposition of tin from the stannous fluoborate bath, relating mainly to the effect of addition agents, to anode sludging, and to electrode efficiencies, is described. Preliminary work on the deposition of tin from the stannous fluosilicate bath is outlined. Some work has been carried out on the deposition of tin-nickel, tin-cadmium, and tin-zinc from fluoborate baths, and on the deposition of tin-cadmium and tin-zinc from fluosilicate baths. This work is still in its early stages and the progress made to date is summarized.
