Abstract
A thermally conductive board includes a top metal foil, a bottom metal foil, and a thermally conductive layer laminated therebetween. The thermally conductive layer includes an electrically insulation matrix and a thermally conductive filler. The electrically insulation matrix includes a fluoropolymer. The thermally conductive filler includes a glass fiber dispersed in the electrically insulation matrix. The glass fiber has a first dielectric constituent and a second dielectric constituent. The first dielectric constituent is a halogen. The total weight of the glass fiber is calculated as 100%, and the halogen accounts for at least 0.05%. The second dielectric constituent is a titanium family element. The total weight of the glass fiber is calculated as 100%, and the titanium family element accounts for at least 0.03%.
