Abstract
Good heat dissipation and insulating properties are required for the insulating sheet mounted on the power module. The sheet is filled with plate-like hexagonal boron nitride (BN) particles. The plate like particles can result in anisotropic thermal conductivity in the sheet, isotropic properties are ensured by orientation suppression. The application of agglomerate BN powder has been studied extensively. This study examines the relationship between orientation and powder characteristics of the agglomerate BN powder. Agglomerate BN powder with a large specific surface area, (i.e. a small particle size and aspect ratio) was most effective in improving the thermal conductivity of the insulating sheet. This is due to the high c-plane orientation suppression when using this powder.
