| Abstract: | The gloss of light emitting diode （LED） pins would affect the welding quality and luminous efficiency, The influence of acid activation, copper plating and silver plating in electroplating process on the gloss of LED pins were investigated. The parameters of electroplating process were optimally selected. The gloss of LED pins can exceed 1.5 by taking the following process： copper inhibitor 60 g/L＋1% H2SO4 acid activation, copper cyanide plating （1 μm）＋copper sulfate plating （1μm）, Ag0-56 silver plating （1 μm）＋silver cyanide plating （3 μm）. It can meet the requirements of the high quality electronic products. |
