Abstract

Abstract PURPOSE:To obtain a strong connection by selectively plating the wire connecting section of a lead frame made of Cu or Cu group alloy or Fe or an Fe group alloy with Cu. CONSTITUTION:The surface of base material itself made of Cu or a Cu group alloy or Fe or an Fe group alloy is hard, but its surface is changed into a soft material when the base material is plated with Cu. Since a wire is connected to the soft material section, adhesive strength is increased and the wire is not exfoliated, and the oxidation of the surface is prevented and connection is strengthened.
