Abstract
A composition for producing a printed circuit board is provided. The composition includes a polyamic acid having one or two crosslinkable functional groups introduced at one or both ends thereof, a liquid crystal polymer (LCP) or a liquid crystalline thermoset (LCT) oligomer, and an organic solvent. Therefore, the composition can be used as a material for next-generation boards that are becoming gradually lighter in weight and smaller in thickness and size. Further provided is a printed circuit board produced using the composition.
