Abstract

A simple, inexpensive method and apparatus are provided for increasing the thickness of a body molded on a semiconductor package without the need for a new mold, or for reworking the parts of an existing mold. The method includes providing a mold having parts that engage each other at respective interfacial surfaces, and a shim having a selected thickness and an opening through an interior portion thereof. The shim is interposed between the interfacial surfaces of the mold parts such that the mold parts are spaced apart by the thickness of the shim, and such that the mold parts and the shim opening define a cavity in the mold. The length and width of the cavity of the mold thus remain the same, while the height of the cavity, and hence, the thickness of the molded body, is increased by the thickness of the shim.
