A copper clad laminate includes a glass fiber substrate and at least a copper foil on the glass fiber substrate. The glass fiber substrate is made by impregnating glass fiber fabrics in an impregnation liquid to form prepregs, and then the prepregs are laid up with a copper foil to form the copper clad laminate by a hot press molding. The impregnation liquid includes resin and a filler in a range between 5 PHR and 80 PHR, wherein the filler includes silica and at least a metallic oxide, of which a metallic atom is selected from the groups IIA or IIIA elements in the periodic table, to form a composite material with an amorphous network structure that the copper clad laminate will have a suitable hardness and a coefficient of thermal expansion. |
