Claim:
1. A semiconductor device package on package assembly, comprising: a first package comprising a first surface, a second surface substantially opposite the first surface, a first die, and a first set of electrical conductors coupled to the first surface and configured to electrically connect the package on package assembly; a second package comprising a substrate having a third surface and a fourth surface substantially opposite the third surface, and a second die, wherein the third surface is coupled to the second surface, and wherein the first package is electrically coupled to the second package, the substrate further including a fifth surface that is substantially perpendicular to the third surface and the fourth surface; at least one exposed thermal conductor positioned in the second package on the fifth surface of the substrate such that the at least one exposed thermal conductor exposes through a perimeter surface of the second package; a plurality of wires positioned in the second package thermally coupling the first die to the at least one exposed thermal conductor; and a shield on the fourth surface of the semiconductor device package assembly, wherein at least a portion of the shield directly contacts the at least one exposed thermal conductor on at least a portion of the fifth surface of the substrate of the second package, wherein the shield is thermally coupled to the at least one exposed thermal conductor, and wherein the shield transfers, during use, heat from the first die.
