Patent number: 6046907Abstract: A heat conductor used by being disposed between a heat sink and electronic parts mounted on a printed circuit board. The heat conductor is layered by a heat conductive layer, made of silicone gel with alumina as a heat conductive filler dispersed therein, and a potentially adhesive layer. The potentially adhesive layer consists of a hot melt layer, with alumina as a heat conductive filler dispersed therein, and a heat resistant film, to facilitate formation of the hot melt layer, adhered to the heat conductive layer on one face of the heat resistant film. The heat conductor is set on the electronic parts so that the potentially adhesive layer abuts them, and is made to adhere to the electronic parts due to heating by means of reflow soldering to reach the phase change temperature of the adhesive.Type: GrantFiled: September 16, 1999Date of Patent: April 4, 2000Assignee: Kitigawa Industries Co., Ltd.Inventor: Akio Yamaguchi
