Claim:
1. An electrical module, comprising: a pair of electrically interconnected substrates, each having corresponding sets of electrical contacts in mutual contact, at least one of the substrates having a set of electrical contacts formed of a deformable metal which are deformed but not fused to the corresponding set of electrical contacts of the other substrate at an intercontact region; a solid matrix adhered to the pair of electrically interconnected substrates except between the corresponding sets of electrical contacts, formed from a curable liquid adhesive, and having a prestress sufficient to maintain a compressive force between the respective sets of electrical contacts of the pair of electrically interconnected substrates, the formed solid matrix maintaining adhesion and mechanical integrity over an entire range of temperatures between about +50 C to −175 C, substantially without fusion of the corresponding sets of electrical contacts; and wherein the solid matrix is formed from the curable liquid adhesive having a viscosity at 20 C of less than about 1000 cp.
