titleOfInvention | Semiconductor Leadframes with Multiple Plating Layers |
abstract | The present invention relates to a semiconductor leadframe having multiple plating layers.n n n A metal substrate; A copper-nickel alloy layer formed on the substrate; And a palladium or palladium alloy layer formed on the copper-nickel alloy layer.n n n According to the present invention, by forming a copper-nickel alloy layer on a metal material substrate, it is excellent in ductility and can enhance wear resistance, corrosion resistance and heat resistance. Therefore, since the internal stress of nickel is minimized during the trimming or forming process performed in the semiconductor assembly process, the occurrence of cracks can be reduced. |
