Title:
ELECTRICALLY CONDUCTIVE BAR STOCK AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/194738
Kind Code:
A1
Abstract:
[Problem] To provide an electrically conductive bar stock in which diffusion of the basic component into Sn is limited even after keeping at high temperature for a long period, and as a result, increases in contact resistance can be limited; and a manufacturing method therefor. [Solution] An electrically conductive bar stock 10 obtained from an electrically conductive base material 1 of copper or a copper alloy and multiple plating layers (2, 3, 4), wherein the number of intersections between the interface, which is between the electrically conductive base material 1 and a first intermediate layer 2 provided on said electrically conductive base material, and grain boundaries of the first intermediate layer 2 is 15-120 per 10 µm of interface length; and a manufacturing method therefor.
