| 摘要 |
The present invention relates to a resin composition for a package substrate and a package substrate comprising a core layer and a prepreg using the same, which include a polyester amide liquid crystal oligomer, a bisphenol tetrafunctional epoxy resin, a curing agent, and an inorganic filler, wherein the bisphenol tetrafunctional epoxy resin has a viscosity of greater than 20,000 cps. According to the resin composition for a package substrate in accordance with the present invention can provide a package substrate with reduced substrate warpage by improving heat radiation characteristics of a substrate material. Further, it is possible to improve defects by reducing delamination between a chip and the substrate or occurrence of cracks of solder balls through the reduced substrate warpage characteristics. |
