Abstract: An apparatus for removing heat from the top surface of an electronic package. In one embodiment, an electronic package is attached to the top-side of a printed circuit board. The printed circuit board has a first set of through holes positioned symmetrically about the electronic package. A heat sink is placed in thermal contact with the top surface of the electronic package. The heat sink has a second set of through holes that correspond and are align with the first set of through holes. Posts having a first end portion and a second end portion are positioned within the first and second set of through holes such that the first end portions are in abutting engagement with the top surface of the heat sink, and the second end portions protrude from the bottom-side of the printed circuit board. The heat sink is held in place by a spring clip. The spring clip includes a substantially flat cross member and a pair of legs extending outward from either side of the cross member.
