2-STEP THERMOSETTING ANISOTROPIC CONDUCTIVE ADHESIVE COMPOSITION AND ANISOTROPIC CONDUCTIVE ADHESIVE FILM

摘要

A 2-step thermosetting anisotropic conductive adhesive composition is provided to maintain stability at a wide temperature, low contact resistance and excellent adhesive force by using two kinds of thermosetting radical initiators with different 10 hours half life. A 2-step thermosetting anisotropic conductive adhesive composition comprises (A) thermosetting resin 5-70 parts by weight, (B) (meth)acrylate oligomer 1-50 parts by weight, (C) (meth)acrylate monomer 1-50 parts by weight, (D) thermosetting radical initiators with different 10 hours half life 0.1-15 parts by weight, (E) conductive particles 0.01-20 parts by weight, and (G) solvent 5-70 parts by weight. The thermosetting radical initiators comprise a low-temperature thermosetting radical initiator with 10 hours half life lower than a drying condition within 15 °C range and a high-temperature with 10 hours half life higher than the drying condition.
