IC leads plating

IC lead frame and lead plating is a core surface finishing process in semiconductor packaging. Functional metal coatings are electroplated onto the metallic leads of integrated circuits to improve solderability, resist oxidation and corrosion, strengthen wire bonding performance, and optimize electrical and thermal conductivity, Copper alloy lead frames (C194, C7025, etc.); Typical plating layers: pre-nickel strike, microporous nickel, bright tin, matte tin, tin-bismuth alloy, palladium-nickel, gold, silve...
