Electrically conductive adhesives are composites of polymeric matrices and electrically conductive fillers. The polymeric resin, such as an epoxy, a silicone, or a polyimide, provides physical and mechanical properties such as adhesion, mechanical strength, impact strength, and the metal filler (such as, silver, gold, nickel, or copper) conducts electricity. Metal-filled thermoset polymers were first patented as electrically conductive adhesives in the 1950s. Recently, electrically  conductive adhesive  materials have been identified as one of the major alternatives for lead-containing solders for microelectronics packaging applications. Electrically conductive adhesives offer numerous advantages over conventional solder technology, such as environmental friendliness, mild processing conditions which enable the use of heat-sensitive and low-cost components and substrates, fewer processing steps which reduce processing cost, low stress on the substrates, and fine-pitch inter...
