Abstract
A pressure clip for contacting a heat sink device to a heat sink by means of a pressure bond having thermal resistance of less than about 5 K/kW/cm.sup.2. The pressure clip includes a mounting block, a clamp block; a spacer disposed between the mounting block and the clamp block forming a channel therebetween, support shoulders in the channel for supporting a heat sink, means for securing the clamp block and the spacer to the mounting block, pressure arm disposed above the mounting block, flexible joint for flexibly attaching the pressure arm to the mounting block, pressure screw disposed between the pressure arm and the mounting block for applying pressure to the pressure arm, and a plunger projecting into the channel between the mounting block and the clamp block for transmitting pressure from the pressure arm.
