friend. Be patient.

Ken,
If you need get rid of a lot of heat, there is a nice way. If you plan
for thousands of boards, it may be worth having a look at. You drill
holes, put copper plugs in, and deform them slightly with a pressure
tool. If your are interested, I can ask the inventor for permission to
send information I have.  But, as I said, it's for real mass production.

Do any of you see an issue with putting thermal via's under the bodies
of a D2PAK? Do you have any recommendations for the number or size or
the via's to help transfer heat to the other side of the board?

Thanks,

KennyB
