US 2015/0147542 A1 · RESIN COMPOSITION FOR PRINTED CIRCUIT BOARD AND PRINTED CIRCUIT BOARD COMPRISING THE SAME

Abstract

A resin composition for a printed circuit board and a printed circuit board formed of the same. The resin composition for a printed circuit board may have: a liquid crystal oligomer including a structural unit of the Chemical Formula 1 and a structural unit of the Chemical Formula 2 and including a functional group of the Chemical Formula E on at least one end; and an ether-type naphthalene-based epoxy resin of Chemical Formula N. According to an exemplary embodiment, even though a printed circuit board becomes light, thin, and miniaturized, electric, thermal, and mechanical stability of the printed circuit board may be secured.
