Abstract
The present invention provides a halogen-free thermosetting resin composition, a prepreg, a laminate and a printed circuit board comprising the same. The halogen-free thermosetting resin composition comprises, based on 100 parts by weight of organic solids, (A) from 30 to 60 parts by weight of a halogen-free thermosetting resin, (B) from 10 to 35 parts by weight of a phenolic curing agent, and (C) a phosphorus-containing flame retardant. The prepregs, laminates and printed circuit boards prepared from the halogen-free thermosetting resin composition of the present invention have excellent dimensional stability and dielectric properties, high adhesive force, high heat resistance, low water absorption and better processability, and can achieve halogen-free flame retardancy and reach UL94 V-0.
