Patent attributes
A heat dissipation assembly has a containment apparatus preventing unwanted migration of a thermal interface material to surrounding areas on a top surface of a heat sink. The containment apparatus includes a cap correspondingly covering the thermal interface material and an annular frame extending downwardly from a bottom end of the cap and attached to a periphery of a top of the heat sink. The cap includes a ceiling and a plurality of inclined sidewalls extending downwardly and outwardly from edges of the ceiling, thereby forming a protective space within the cap combining with the top surface of the heat sink to enclose the thermal interface material. Two ears extend outwardly from the frame and accommodate opposite ends of an abutting body of a wire clip therein.
