Abstract
Disclosed is a resin composition, comprising the following components: (A) 100 parts by weight of an epoxy resin; (B) 10 to 60 parts by weight of a diamino diphenyl ether type benzoxazine resin having a softening point of 40° C. to 140° C.; (C) 10 to 40 parts by weight of a co-hardener; and (D) 10 to 40 parts by weight of a flame retardant which comprises (d1) a high melting point flame retardant with a melting point of greater than 260° C. or (d2) a metal phosphinate flame retardant, wherein the metal is selected from Group IIIA elements. Also disclosed is an article of manufacture obtained from the resin composition and a use thereof. Accordingly, the demands of high frequency application can be met, and a balance of low thermal expansion, high thermal resistance and low warpage in the system can be struck.
