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.
