ANISOTROPIC THERMALLY CONDUCTIVE COMPOSITE SILICONE RUBBER SHEET AND PRODUCTION METHOD OF THE SAME

摘要

To provide an anisotropic thermally conductive composite silicone rubber sheet, in which no degradation of thermal conductivity due to generation of void occurs, by achieving high adhesion between a heat generator and a heat radiation member, and to provide a production method thereof.SOLUTION: An anisotropic thermally conductive composite silicone rubber sheet 5 is formed by alternately juxtaposing, over at least respectively five or more layers, thermally conductive silicone rubber layers 1 each containing a thermally conductive filler and having Asker C hardness of 2 to 30, and fiber cloth layers 2 having high thermally conductive fibers of which the warp impregnated with silicone rubber or silicone resin has thermal conductivity of 100 W/mK or more.SELECTED DRAWING: Figure 1
