SOLDERED STRUCTURE USING Zn AND METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a soldered structure in which structure characteristics are improved by intervening in interfacial reaction in the case of soldering high reactive Zn.

SOLUTION: The soldered structure includes a coupling layer containing Zn and Pb-free solder that coupling-reacts with the coupling layer. Then, the coupling layer has a multiple layer structure in which at least one material layer formed by a predetermined material and a Zn layer are sequentially laminated; and the Zn layer is located at the uppermost position on the Pb-free solder side of the multiple layer.
