LEAD-FREE TIN PLATED MEMBER AND METHOD OF FORMING PLATING LAYER

摘要

In a plated member (3) that has a pure Sn plating layer (2) of a lead-free material on a surface of a base material 1, the orientation indices of a (101) plane and a (112) plane of the pure Sn plating layer are increased to values higher than the orientation indices of the other crystal orientation planes.
