ABSTRACT:
An electronic package having an active cooling system for maintaining a semiconductor chip at approximately a constant temperature by monitoring the present temperature of the chip and varying the air flow over a heat sink in thermal contact with the chip in response to the temperature. In addition, the temperature difference between the semiconductor chip module and a printed circuit board is also monitored to maintain that difference at a preset value. The air flow is varied by a variable speed fan or a variable direction baffle.
