ABSTRACT:
A 51/2" by 53/4" flat ceramic board is bonded to an aluminum frame which serves as a heat sink. The bonding agent intermediate the board and the frame is thermally conductive and comprises an epoxy containing Master Bond EP21TDCAOHT. The formed laminate or bond is capable of withstanding repeated stresses occurring through thermal cycling in temperatures from -60 degrees centigrade to +125 degrees centigrade and vibration and humidity testing.
