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.

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 PSXP are adaptable to current equipment systems
• Eliminates expensive TIM evaluation by the semiconductor end users

Why Loctite PSX-D and PSX-P?
• Compared to other TIM products in the market, PSX-D and PSX-P is
available in multiple dry time formulations vs. the competitive
products only available in ultra fast dry formulations
• PSX-P is optimized for automated stencil printing, while other similar
products in the market are optimized for manual screen printing only
• Improved long-term thermal reliability because of the elimination of
“pump-out”
• Henkel offers technical support for our Loctite TIM products globally
