Description

Technical field [0001] The invention relates to the technical field of paint production, in particular to a polycarbonate insulating and thermally conductive composite material and a preparation method thereof. Background technique [0002] In recent years, microelectronics devices are developing in the direction of high performance and high integration. Accompanying this is the continuous increase in the heating power of electronic components. Various types of microelectronics technology applications have also generated further demand and dependence on thermal management materials. . Although diamond / copper, SiC / Al and other composite materials, as a new generation of thermal management materials, have high thermal conductivity and suitable thermal expansion coefficient, due to the existence of metal matrix, they cannot be used to require specific insulation or dielectric properties. Application occasions. For example, in addition to electrical insulation for integrated circui...
