Abstract
Official abstract text for this publication.
Provided is a method of manufacturing a heat conductive sheet with improved adhesion and heat conductivity. The method includes the steps of molding a heat conductive resin composition, which includes heat conductive fillers and a binder resin, into a predetermined shape and curing the heat conductive resin composition to obtain a molded product of the heat conductive resin composition, cutting the molded product into sheets to obtain a molded product sheet, and pressing the molded product sheet.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heat conductive sheet, comprising: a sheet main body made of a cured heat conductive resin composition, in which heat conductive fillers are dispersed in a binder resin, wherein a surface of the sheet main body is coated with an uncured component of the binder resin oozing from the sheet main body. 2. The heat conductive sheet according to claim 1 , wherein the entire surface of the sheet main body is coated with the uncured component of the binder resin oozing from the sheet main body as a result of pressing. 3. The heat conductive sheet according to claim 1 , wherein the heat conductive fillers comprise carbon fibers, and the carbon fibers that are present on the surface of the sheet main body are coated with the uncured component of the binder resin oozing from the sheet main body. 4. The heat conductive sheet according to claim 1 , wherein the sheet main body is obtained by integrating a plurality of molded product sheets, each molded product sheet being made of the cured heat conductive resin composition, which includes the heat conductive fillers and the binder resin. 5. The heat conductive sheet according to claim 3 , wherein the sheet main body is obtained by integrating a plurality of molded product sheets, each molded product sheet being made of the cured heat conductive resin composition, which includes the heat conductive fillers and the binder resin.
