Boron Nitride Powders for High Thermal Conductivity Insulation Resin Sheets


In recent years, demand for power modules used in industrial and automotive inverters has been extremely high in applying hybrid electric vehicles (HEV) and electric vehicles (EV). Although ceramic-type insulated heat dissipation substrates had been used for power modules until recently, a changeover from ceramic materials is now in progress due to the development of high thermal conductivity insulation resin sheets using boron nitride fillers. Mizushima Ferroalloy Co., Ltd., a wholly-owned subsidiary of JFE Steel Corporation, developed and commercialized a series of aggregate hexagonal boron powders (HP-40 Series) as fillers for use in high thermal conductivity insulation resin sheets for high-output power modules. g filler material. H-BN displays a planar shape and has anisotropic thermal conductivity originating from its crystal structure, as its in-plane thermal conductivity is high (200 W/m-K). Its through-plane thermal conductivity (in the thickness direction) is low (2 W/m-K). However, when h-BN was filled in resins and formed into sheets without modifying its planar shape, it was impossible to increase the through-plane thermal conductivity of the resin because the planar particles oriented in the in-plane direction in the sheet. To solve this problem, Mizushima Ferroalloy developed aggregate BN powders with a random orientation of planar h-BN. It is possible to increase through-plane thermal conductivity by producing an aggregate powder and filling the resin while maintaining this morphology.
