Abstract:
1. A method for providing a semiconductor chip package with solder wettable plating, the method comprising: singulating a semiconductor chip package from an array of packages formed in a block format, the singulated semiconductor chip package comprising at least one lead land, the at least one lead land comprising a bottom land portion and a side land portion, the side land portion oriented at least substantially perpendicular to the bottom land portion; immersing the singulated semiconductor chip package in a bath of plating solution; contacting the bottom land portion of the lead land of the singulated semiconductor chip package with conductive contact material within the bath of plating solution; connecting the conductive contact material to a cathode electrical potential; connecting an anode within the bath of plating solution to an anode electrical potential; and electrolytically plating the lead land of the singulated semiconductor chip package with solder wettable plating, wherein the solder wettable plating is plated onto the side land portion of the lead land.
