description La présente invention se rapporte à une composition adhésive pour la fixation de dés, comprenant un mélange homogène fait d'un monomère de bibenzocyclobutène couplé en pont avec un organopolysiloxane, d'un auxiliaire d'adhérence à base d'organosilane et d'un métal électroconducteur en fines particules. La composition est facile à appliquer, présente une bonne adhérence et une bonne stabilité thermique à hautes températures et ne nécessite pas de solvants, d'excitants ou d'agents de polymérisation. La perte de poids lors de la polymérisation est minime. The invention is a die attach adhesive composition comprising a homogeneous blend of an organopolysiloxane-bridged bisbenzocyclobutene monomer, an organosilane adhesion aid, and a finely divided electrically conductive metal. The composition is easy to apply, exhibits good adhesive strength and thermal stability at high temperatures, and does not require solvents, initiators, or curing agents. Weight loss on cure is minimal.
