Abstract
Electrically conductive sheet material preforms useful in bonding of electronic components as well as in the formation of electronic circuits are disclosed. The preforms, which comprise a multiplicity of electrically conductive adhesive members, each being separated from each other by means of a non-electrically conductive adhesive, are particularly useful in the assembly of multi-chip modules and other electronic devices.
Claims14
An electrically conductive adhesive sheet material suitable for use in connecting electronic components together comprising a multiplicity of electrically conductive adhesive members each having a bottom surface and a top surface, each of said members being separated from each other by means of a non-conductive adhesive region disposed between said conductive adhesive members, each non-conductive member having a bottom surface and a top surface, said conductive adhesive members and said non-conductive adhesive region being joined together to form an integral sheet material having a planar bottom surface formed of the conductive and non-conductive adhesive members, with the top surface of each of the conductive adhesive members extending beyond the top surface of each of the non-conductive adhesive members, said conductive adhesive members comprising a first adhesive resin and an electrically conductive metal filler, and said non-conductive adhesive region comprising a second adhesive resin.
