ELECTRICAL CONNECTION STRUCTURE, INSULATING MEMBER WITH WIRING AND PRODUCTION METHOD OF THE SAME AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electrical connection structure capable of effectively suppressing the diffusion of a component (e.g. nickel) contained in a base plating layer to a surface plating layer to improve the connection stability and reliability of the surface plating layer to a conductive connection material and to improve repairing property.;SOLUTION: In an insulating member 30 with wiring which is formed by laminating and forming the base plating layers 35, 36 and the surface plating layers 37, 38 on the prescribed parts of wiring layers 31, 32 formed in the insulating member 30, the whole of surface layers 35B, 36B where the base plating layers 35, 36 is contact with the surface plating layers 37, 38 has a solid solution containing at least nickel and one of cobalt and iron.;COPYRIGHT: (C)2007,JPO&INPIT
