Process for manufacturing ball grid array package

A ball grid array package is manufactured by mounting a semiconductor die to a first surface of a substrate array. Wires are bonded between the semiconductor die and ones of conductive traces of the substrate array. The heat spreader is disposed in a mold and the substrate array is releasably clamped to a top die of the mold. The semiconductor die, the substrate array, the wire bonds and the heat spreader are molded into a molding material to provide a molded package. Next, the molded package is removed from the mold and a plurality of solder balls are added in the form of a ball grid array on a second surface of the substrate array such that bumps of the ball grid array are electrically connected to the conductive traces. The integrated circuit package is then singulated from a remainder of the substrate array.
