Flip Chip Assemblies with Underfill Encapsulants
The development of epoxy based underfill encapsulants marked a turning point for flip chip technology, and the semiconductor industry. Underfill encapsulants are carefully formulated to ensure flowability, an acceptable CTE, and other desirable properties. In this white paper, we explore what properties are required for effective underfills to ensure reliability and quality in flip chip applications.

Importance of CTE of Adhesives for Assembly Reliability
Forming reliable bonds between different materials can be challenging because there can be large variations in CTE's (coefficients of thermal expansion). Adhesive compounds play a critical role in the fabrication of assemblies for electronic, optical and mechanical systems. Learn more about typical CTE's for various chemistries such as epoxies and silicones, how fillers can be used to modify CTE, why CTE is dependent on temperature and much more. Specific case studies illustrate the thermal compounds used. Teaser: Is there a solution to the thermal expansion mismatch of components for an electronic assembly? You bet, and one solution is to use a specialized adhesive that can withstand thermal expansion effects.

Epoxies and Glass Transition Temperature
Gain a better understanding about glass transition temperature (Tg) and why it is one of many factors to consider for bonding, sealing, coating and encapsulation applications. In this paper, we explore how temperature impacts the performance of polymers, why glass transition temperature is significant, and how it is measured. Tg can be an extremely useful yardstick for determining the reliability of epoxies as it pertains to temperature.

One -Component Epoxies Offer Versatility and Ease of Use
To understand one part epoxy systems, you need to know how a two part system works. In this white paper, we explore how a one part system is constructed, how it can and should be used, and how it can be modified to achieve a variety of performance properties. Also learn how technological advances have resulted in innovative, unique systems.

Epoxy Compounds Get Even Tougher
With adhesive products, high performance and rigidity are often thought to go hand in hand. It is true that the very best strength, thermal, chemical and electrical properties tend to be found in rigid compounds, especially epoxies. Yet there is a growing class of adhesives, sealants and coatings that add ductility to the long list of desirable epoxy properties. Master Bond’s whitepaper examines the use of these toughened epoxies.
