Phil,

As an alternative option, you might try one of Bergquist's materials - Gap
Filler 2000. 

It is an elastomer which cures, thereby eliminating the bleeding of the
normal grease with temp cycling.

Thermal conductivity is 2 W/m°K.  Cure time is 1-2 hours at room temp.

Subject: [TN] Application of Thermal Grease


We use many TO-220 and TO-247 packages mounted to heatsinks.  Some of
these applications require the use of thermal grease.  The age old
question is how much grease is enough?  This is a political football
that is constantly tossed around.  Does anyone know of a manufacturer's
specification or some organization's standard that clearly defines how
much thermal grease is the correct amount?

Thanks,

Phil Nutting
