Properties and Applications of Advanced Die Attach Epoxy Adhesives

Master Bond's advanced die-attach adhesives are increasingly accepted for the most demanding microelectronic semiconductor packaging as well as for chips-on-board assemblies. Both one component heat curing and premixed and frozen formulations are available. They include electrically and thermally insulative, thermally conductive, electrically insulative and thermally-electrically conductive compounds. For special uses fast curing two component systems are offered. They all offer outstanding bonding strength for adhering components directly onto printed circuitry.

Features of Advanced Die Attach Epoxy Adhesives

The Master Bond die attach epoxy compounds are 100% reactive and do not contain any volatiles. They have excellent resistance to both thermal cycling and mechanical shock and vibration. Their dimensional stability is remarkable, even upon prolonged exposure to adverse environmental conditions. These high-performance epoxy compounds can be readily dispensed by syringes and other conventional devices as well as by specialized printing technologies. For certain optoelectronic uses unique UV curable compounds are employed as they offer unmatched curing speeds and hence higher productivities.
