Mike,

I don't know your application but I guess you may visit www.bergquistcompany.com
to look at their HiFlow series. Many other companies make phase change material
(Chomerics, 3M, etc.) but so far we only tested the Bergquist's. HiFlow melts at
60degC which is just right for my application. We tested both the insulated and
non-insulated verisons. Their thermal impedance is far better than the silicone
rubber pad, and unlike silpad, you get very consistent thermal impedance
regardless of the clamping pressure between the power source and the heat sink.

Subject:  [TN] Phase change materials




Have an application coming up which will require application of a phase change
material as
thermal coupler. If anybody has any info background on methods of application
etc  they could
share with me I would be grateful.


Mike
