Abstract:
1. An electronic package comprising: a heat sink; a flexible circuit including a plurality of conductors thereon; a semiconductor chip positioned on said flexible circuit and electrically coupled to selected ones of said conductors; a quantity of heat shrunk adhesive positioned on said flexible circuit and bonding said flexible circuit to said heat sink such that said flexible circuit having said semiconductor chip positioned thereon is substantially planar; and a plurality of separate standoffs positioned between said heat sink and said flexible circuit to separately contact and maintain at least part of said flexible circuit at a spaced distance from said heat sink, so as to limit motion of said flexible circuit due to permanent volumetric shrinkage of heat shrunk adhesive; wherein at least one of the plurality of separate standoffs does not contact the heat shrunk adhesive, and wherein at least one of said plurality of separate standoffs is positioned within said quantity of heat shrunk adhesive.
