[Test-Equipment] OT: heat transfer paste

[Jerry Mulchin]

Rasputin,

Yes this is the trend now in heatsink material. It is an insulator
also. It is better in that the amount of material is uniform, where
the paste had to be put on very thin. And it is a lot better to
handle than the paste.
I don;t know what the material is, but if you go to webpages
for Avvid or Thermaloy and others, they should be able to
give you a description. They can be gotten from places like 
Digikey, Mouser and others.
