CORE SUBSTRATE AND METHOD OF MANUFACTURING CORE SUBSTRATE

摘要

PURPOSE: A core substrate and a manufacturing method thereof are provided to improve heat radiation efficiency by including an inorganic filler with high thermal conductivity. CONSTITUTION: A core substrate comprises an adhesive resin layer(130), a metal sheet(121), and an insulation layer(140,160). The adhesive resin layer includes an inorganic filler. The inorganic filler includes alumina or silica. A metal sheet is embedded in the adhesive resin layer. The insulation layer is laminated on both sides of the adhesive resin layer.
