Die Attach Epoxy Adhesives
Master Bond's advanced die attach adhesives are increasingly accepted for demanding microelectronic semiconductor packaging as well as for chip on board assemblies. They offer outstanding bond strength for adhering components directly onto printed circuitry. These systems are presently employed in the assembly of many critical electrical devices used in commercial, military, space and medical applications.
Types of Die Attach Epoxies
Master Bond die attach adhesives are available in one component heat curing formulations and premixed and frozen compositions. Fast curing, two component systems are also obtainable for special uses. For certain optoelectronic requirements unique UV curable compounds are employed as they offer unmatched curing speeds and higher productivity.
