OK, maybe I'm preaching to the choir, but I had a specific problem this
week. I needed to mount some TO-220 (uninsulated case) transistors on a
metal chassis, without any drilling. After some searching, I found some
stuff from Jaycar, for a surprisingly reasonable price. Part # NM2790. It's
double-sided tape, thermally conductive and rated for 3,500 Volts and 250oC.
I haven't had the opportunity to measure thermal resistance, but the case
temperatures have fallen from >75oC to less than 30oC. Quick, easy and
reasonably priced.

BTW: Jaycar rate the stuff at 1.6/m-k. I'm not certain how that translates
to #oC/W.

I'm a happy puppy and I know my client will be too.

Depends on the material thickness and area of the copper tab on the package.
