The present invention relates to an epoxy resin composition, and a prepreg and a copper clad laminate made therefrom. The epoxy resin composition comprises the following essential components: (A) at least an epoxy resin, of which the melt viscosity is not more than 0.5 Pa�s under the temperature of 150 � C.; (B) phenolic resin, of which the structure is as shown in the formula 1: wherein, n represents an integer of 0-10. The epoxy resin composition of the present invention can provide the prepreg and copper clad laminate made therefrom with high glass transition temperature, high heat resistance, low expansion coefficient and low moisture absorption, which can meet demands of high reliability of high density multi-layer PCBs. |
