FIXING APPARATUS FOR HEAT SINK

摘要

A fixing apparatus adapted for attaching a heat sink to a circuit board on which an electronic component is mounted includes a fastener and a back plate. The fastener comprises an elongated pressing part holding the heat sink in contact with the electronic component and two latching legs extending downward from two opposite ends of the pressing part. The latching legs each have at least one hook extending inward from a distal end thereof. The back plate comprises a main body and a plurality of connecting members at two opposite ends of the main body for extending upwardly through the circuit board to engage with the hooks of the fastener.
