Abstract: A spring clip manufactured from a single piece of metal for attaching an electronic component to a heat sink for defining a heat dissipation assembly. The spring clip comprises a main body having a bend with a cantilever on one side of the bend and a mounting region terminating in an engaging edge on the other side of the bend. Outriggers project perpendicularly from both sides of the mounting region and extend beyond the engaging edge In the assembly outriggers project through slots in the heat sink and the electronic component is secured between one side of the heat sink and the engaging edge of the spring clip. The outriggers preferably include retaining members which abut the opposite side of the heat sink thereby resisting rotation of the spring clip relative to the heat sink.

Abstract: A heat sink (60) comprising thermally conductive legs (72, 74) for coupling to a heat pad (64), a plurality of heat-convecting fins (86) that are thermally coupled to the legs, and a surface (80) cantilevered by support structure (82) coupled between the legs (72, 74). One or more heat-convecting fins (88, 90) may extend directly from the support structure (82). A method for making the heat sink is also disclosed.

Abstract: A heat sink spring clip having a linearly displaceable deflection member that operatively engages a biasing member for thermally and mechanically connecting a heat sink to an electronic component. The deflection member is moveable in a generally linear manner on and relative to the biasing member between a first position of nonengagement in which the biasing member is substantially undeflected and a second position in which the biasing member is deflected and the deflection member is contactingly and operatively engaged with the heat sink for thermally and mechanically connecting the heat sink to an electronic component. As the deflection member is moved from the disengaged position to the engaged position, complementary elements on the biasing member and deflection member engage one another and cause portions of the deflection and biasing members to move relatively apart.
