Non-cyanide gold-palladium alloy plating solution and plating method

摘要

PROBLEM TO BE SOLVED: To provide a non-cyanogen system gold-palladium alloy plating solution that can make the appearance of a plating film excellent and can reliably suppress generation of defects such as a crack to the plating film.SOLUTION: The present invention relates to a non-cyanogen system gold-palladium alloy plating solution containing gold salt, palladium salt and appearance modifier, and is characterized in that the solution contains phosphate as appearance modifier and one or more of tellurium and/or selenium. It is preferred that the solution further contains hydantoin-type compound.
