ABSTRACT:
A spring clip fastener (10) is provided for mounting a heat sink (40) and a semiconductor device package (42) to a circuit board (44). Spring clip fastener (10) includes a spring portion (12). Support members (14, 16) extend from the spring portion (12) for supporting the spring portion (12) above the surface of the circuit board (44). A shoulder (18, 20) is contained within the support members (14, 16), such that the spring portion (12) urges the semiconductor device package (42) against the heat sink (40). Feet (30, 32) extend from support members (22, 24) for engaging holes (46, 52) of the circuit board (44). Feet (30, 32) are coated with a solder-promoting material.
