Abstract

<p>In recent years, heat dissipation and high heat resistance properties are required to the insulating material due to the high performance and downsizing of power module products. In this paper, the research contents of the resin composite material filled with the high thermal conductivity filler in the cyanate ester resin were introduced. Cyanate ester resin is an excellent insulating material with good formability due to low viscosity and very high heat resistance. The thermal conductivity of resin composite materials was dramatically improved by orientation control of boron nitride (BN) particles using agglomerated BN consisting of flake-like BN particles. The resin composite material with excellent heat resistance and heat dissipation has been developed by blending agglomerated BN into the cyanate ester resin.</p>
