Method for depositing solder onto aluminum metal material

摘要

A method for depositing solder onto aluminum metal material comprises steps of: (a) activating the surface of aluminum metal; (b) substituting zinc for the surface of aluminum as activated; (c) forming a nickel coating film over the surface of the zinc-substituted layer on the aluminum metal material by the non-electrode plating; and (d) attaching soldering material onto the nickel coating film surface.
