PLATED MATERIAL, PRODUCTION METHOD THEREOF AND ELECTRICAL AND ELECTRONIC PARTS OBTAINED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a plated material which combines satisfactory heat resistance and inserting/extracting properties. SOLUTION: An undercoat layer 2 consisting of any one kind selected from Fe or an Fe alloy, Ni or an Ni alloy, and Co or a Co alloy, the first intermediate plating layer 3 consisting of Sn or an Sn alloy, the second intermediate plating layer 4 consisting of Cu or a Cu alloy and a surface plating layer 5 consisting of Sn or an Sn alloy are formed on the surface of an electrically conductive substrate 1 in this order.
