Abstract:
1. A method for preparing a conductive interconnect, comprising: applying an adhesive material on a surface of a first substrate and over an electrical contact protruding from said surface, the adhesive material comprising a resin that does not expand upon curing and particles comprising a pre-cracked core of an electrically conductive material within a coating of an electrically non-conducting material; mounting a second substrate on the first substrate with the adhesive material therebetween, the second substrate comprising an electrical contact protruding from a surface and aligned with the electrical contact on the first substrate; and positioning said first and second substrates such that the coating and the core of at least some of the particles situated within the adhesive material between said aligned electrical contacts are broken and the conducting material of said particles is exposed and in contact with said electrical contacts.
