Abstract
An epoxy resin composition comprising (A) 20-80 parts by weight of an epoxy resin, (B) 20-80 parts by weight of a curing agent, (C) 0.1-50 parts by weight of a phosphorus-containing flame retardant, and (D) 200-1,200 parts by weight of an inorganic filler cures into products having improved high-temperature exposure resistance, flame retardancy, and reflow cracking resistance. The composition eliminates blending of antimony trioxide and brominated compounds and is useful in encapsulating semiconductor devices for imparting high-temperature reliability.
