Background

Adhesive manufacturer Master Bond Inc offers over 3,000 different grades of specially designed formulations. They differ in viscosity, cure speed, temperature resistance, chemical resistance, strength, electrical properties, color etc. These products are specifically designed to solve design, manufacturing and repair/maintenance problems. They will increase productivity, reduce waste, save energy and improve your products performance. They are the perfect solution.

Introduction

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.

Epoxies are the most widely used polymeric materials for adhesives, sealants, coatings, pottings and encapsulations and impregnants. They are available in both one and two component systems. Two part systems can be cured at either room temperature or elevated temperature. One part systems must be cured at elevated temperatures (typically 250 - 300°F). One part systems curable by UV light are also available.

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.
