Abstract
A method of preparing a portion of the side of a terminal of an Integrated Circuit (IC) package for solder is disclosed. The method comprises the steps of attaching an IC die to a leadframe comprising a connecting bar, reducing the thickness of a portion of the connecting bar, overmolding the leadframe with a mold compound, removing the mold compound from the reduced-thickness portion of the connecting bar using a laser, coating the reduced-thickness portion of the connecting bar with a solder-wettable material, and cutting through the thickness of the connecting bar within the reduced thickness portion of the connecting bar, wherein the cut has a width that is less than the width of the reduced thickness portion of the connecting bar.
