Selecting the right adhesive product for extreme temperature applications may seem as straightforward as reading temperature resistance values on data sheets. Some engineers will sometimes address temperature issues by simply selecting an adhesive rated for temperatures beyond their application's expected operating temperature.
Selecting the right adhesive is a balancing act as engineers attempt to find products that meet conflicting end-use and manufacturability requirements. Medical device engineers also have to contend with a strict regulatory environment, and therefore often have the toughest time striking that balance.
Designed to mitigate the worst effects of fires, fire retardant materials play a particularly important role in aircraft construction. Used in aircraft, epoxies and silicones must maintain their primary role as adhesives or coatings while exhibiting resistance to heat and flame in accordance with government and industry specifications.
The assembly applications for medical device manufacturers typically come with their own distinctive set of rigorous requirements. This white paper takes a closer look at one and two part silicone medical adhesives.
Advanced power and high frequency communications electronics have become more sophisticated. Fabricating and assembling these devices involves carefully selecting the proper adhesives, die attach compounds, glob-top encapsulants, underfills and potting compounds. Engineers must be familiar with how these systems can affect design so that they meet and exceed performance objectives.
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.
