Direct Immersion Gold is a process in which gold is plated directly on copper as a surface finish for printed circuit board and package appliions. By examining the deposition reaction of the electroless flash gold plating bath, it was confirmed that, copper does not codeposit with gold and also that the main driving force or deposition is an autoalytic reaction. In addition the effects ...
