Tpcm™ 780 is a high performance, inherently tacky, easy to rework phase change thermal

interface material. Developed specifically to meet the high thermal conductivity and low

thermal resistance requirements of today’s demanding processors.

This silicone-free material is so soft that it begins to flow as the temperature is elevated by

just a small amount. Also, since no tabs are required, Tpcm™ 780 eliminates the need for

expensive converting.

• Minimizes contact thermal resistance

by filling the microscopic irregularities

of the components it contacts.

Begins to soften and flow at

approximately 45ºC

• Designed to minimize migration (pump

out) at CPU operating temperatures

using a unique material formulation

that softens, but does not fully

change phase

• Silicone-free for applications that are

silicone sensitive

• Outstanding thermal performance helps

to ensure CPU/application reliability

• No mess due to thixotropic

characteristics which prevent flow

outside of interface

• Very soft at room temperature,

therefore less stress on board

during assembly

• Tabless parts make for easier handling

in the manufacturing environment

• RoHS Compliant

• 94V0 UL Flammability Rating

• Naturally tacky at room temperature,

requiring no adhesive

• Heat sink preheating not required

• Exceptionally high reliability during

storage and after installation

TABLESS PARTS

TABBED PARTS

Easy handling in manufacturing

environment/rapid handling

Marked tab reduces risk of top tab being left

in place during assembly

Eliminating risk of top tab being left in place

during assembly

Tab provides protection from dust and other

contamination during application of pads and

shipping of applied pads
