Abstract
A heat sink/electromagnetic shield assembly for a circuit ele-ment (22) disposed upon a circuit board (20). A spring clip (24) con-taining at least one hooked projection (32) forming the spring is posi-tioned in a confronting relationship with the circuit element (22). A
U-shaped housing (26) is slidingly positioned over the circuit ele-ment (22) and the spring clip (24) to enclose the circuit element (22) and to compress the hooked projection (32) which forms the spring.
Compression of the hooked projection (32) causes the hooked pro-jection (32) to exert a spring force to retain the housing (26) in posi-tion about the circuit element (22). The assembly may be constructed in line during construction of the electrical circuit (22) disposed upon the circuit board (20).
