Abstract
A method and apparatus for mounting a lidless semiconductor device. A lidless semiconductor device, such as a land grid array device comprising a substrate having a semiconductor die mounted thereon is disposed in a socket. The socket includes a plurality of resilient conductive members arranged in a predetermined contact array pattern for conductively coupling conductive contacts on a printed circuit board with corresponding contacts on the underside of the lidless semiconductor device. A first set of springs applies a predetermined force to the substrate to conductively couple the contacts on the substrate to the contacts on the printed circuit board via the conductive members of the socket. Another set of springs urges the bottom surface of a heat sink into thermally conductive abutting relation with the top surface of the semiconductor die. The pressure on the die is less than the pressure applied by the substrate so as to avoid damage to the semiconductor die.
