MANUFACTURING METHOD OF CONDUCTIVE ELECTROLESS PLATING POWDER

摘要

A method for manufacturing conductive electroless plating powder is provided to increase resin displacement, and obtain bond reliability between electrodes by forming a projected conductive powder with a uniform projection size and coating a part without a projection smoothly. A method for manufacturing conductive electroless plating powder comprises the steps of: forming a first electroless metal plating layer(2) on a surface of a core(1) using resin powder; and injecting a transfer metal and a reducing agent simultaneously in the resin powder which is formed with the first electroless metal plating layer to form a transfer metal projection(3). The transfer metal projection uses a metal which is different from the metal used for the first electroless metal plating layer. A second electroless metal plating layer(4) is formed on the first electroless metal plating layer. A gold plated layer(5) is formed on the second electroless metal plating layer.
