Gold coatings for fluxless soldering

Abstract

Gold coatings play an important role in flux-free joining in a vacuum — a method widely used in electronics fabrication. In this process, the gold coating provides a substitute for the flux, ensuring that the surfaces of the joint are oxide free and solderable.
