ABSTRACT:
Dissipation of heat from a socketed leadless electronic chip-carrier package is promoted by a heat-conducting metal socket cap distinctively overlying and guiding heat away from the socketed package fully along a broad planar surface area, the socket cap being of a unitary construction which both mechanically holds the package securely mated with a multi-pin socket and also cools the package by way of an integrated array of heat-radiating elements; edge clasping of the cap with a chip-carrying socket avoids interference with needed conduction of heat away from central areas of the package and cap.
