Here is some good information:

There is a product called Arctic Silver that is very popular with gamers/computer users. I don't know much about it but it's widely available from computer parts dealers like Search under "thermal grease" or "thermal compound".

For recommendations I'd look at manufacturer's website for the device you're using. They may have an app note.

I do know that you want to apply a uniform THIN coat. More is NOT better. At work we use small rubber rollers to apply. Almost like a paint roller.

Greeting all,

I'm getting around to my 2 meter kilowatt SSPA.  My question is which of
the multitude of heatsink compounds do you recommend?  I have read some of
the comparisons mostly dealing with CPU cooling.  But, would like some
input from piratical experience.  The silver formulations seem to do a bit

In addition, I am assuming that I want a layer of the stuff between the
copper heat spreader and the heatsink?
