Epoxy resin compositions for printed circuit board and printed circuit board using the same

摘要

An epoxy resin composition for a printed circuit board includes an epoxy resin; a multi-functional phenol group; a hardening accelerator; and at least one of a compound having a triazine or isocyanurate ring, and a compound containing less than 60 weight percent nitrogen, but not containing a urea derivative. A printed circuit board comprising the epoxy resin composition has low water absorption, excellent heat endurance, and a good adhesion with copper foil.
