Abstract
Disclosed herein is a liquid crystal polyester resin composition and a printed circuit board using the composition. The composition comprises a liquid crystal polyester, a polybenzimidazole and an aprotic solvent. The composition exhibits good thermal stability and has a low dielectric constant. The composition can be advantageously used as a material for printed circuit boards (PCBS) used in semiconductor packages, mobile devices and LCD devices.
