2. Executive Summary
The Defense and Aerospace electronics industry is aggressively moving to smaller and smaller devices.
These miniaturized packages are more highly functioning and generate more heat.
As a result thermal management has become more of a challenge for designers.
Typical approaches such as thermal greases and phase-change materials in pad formats may provide adequate thermal management capability, however, they are not process friendly solutions and do not adequately address today’s through-put requirements.
A new class of printable phase change formulations provide excellent thermal management and resolve many of the process limitations of grease and pads.

4. Loctite PSX-D and PSX-P Product Benefits
Offers flexibility with pattern and thickness vs. a film material
Improved long-term reliability because elimination of “pump-out”
Reduce part number complexity associated with pre-forms
Enables manufacturers of advanced electronic systems to offer their products with a robust pre-applied TIM2 allowing them to differentiate from their competition
Increases semiconductor design ratings by including this advanced TIM2 material in the specifications
No new capital expenditure is normally required, as PSX-D and PSX-P are adaptable to current equipment systems
Eliminates expensive TIM evaluation by the semiconductor end users
