Abstract
A conductive die attach composition containing no solvent and substantially no ionic impurities which comprises: PA1 (a) an epoxy resin system comprising (i) at least one low viscosity epoxy resin; and (ii) at least one epoxy resin hardener; PA1 (b) at least one unsaturated monomer which, when polymerized, is not capable of reacting with said epoxy resin system; PA1 (c) at least one free radical initiator for polymericing said unsaturated monomer; and PA1 (d) finely divided silver particles.
