Apparatus and method of increasing the distance of the gap between a lead frame and a semiconductor die surface in a package assembly. An adhesive layer and a gap increasing layer are disposed between the lead frame and the semiconductor die surface. The gap increasing layer has a thickness selected to reduce likelihood of package particles from being trapped between the lead frame and the die surface. The gap increasing layer includes silver plating, and has a thickness of at least about 300 to 500 microinches.
