AG CONTACTS FOR INHIBITION OF ELECTROCHEMICAL MIGRATION AND METHOD FOR MANUFATURING THE SAME

摘要

Ag- alloy contact points, for restricting an electrochemical migration and manufacturing method, palladium monoxide layer is formed by a heat treatment and is arranged to carry out high-efficient and economic migration prevention, a plating palladium layers can be formed on surface in a contact point, after a pulse plating method. A kind of method, for manufacturing an Ag- alloy contact points for restricting an electrochemical migration, comprising the following steps: by a kind of Ag- alloys, form plating palladium layers (2) on a surface of a contact point (1) and manufactured by a pulse plating method; Palladium monoxide layer (3) are formed on the surface of contact point from palladium membranes by executing a hot-working. Plating palladium layers are made of at least 1 micron thickness to obtain an effective thickness of oxidation palladium layers, are used to restrict an electrochemical migration after executing hot-working. Hot-working is executed at 650-700? five minutes C.
