Abstract
An arrangement for mounting a packaged semiconductor with a heat sink includes the heat sink having a channel formed therein with a pair of opposed side walls and utilizes one or more spring beams acting against one side wall of the channel to urge the semiconductor package into good heat transferring relation or engagement with the other side wall. The arrangement is especially suited for use with TO-220 transistor packages and uses an array of spring beam fingers joined by a spine in comb-like fashion to facilitate assembly.
