Sure, there are even better things you can do. If your R&D budget can afford 2 month clean-room run, I can share with you what can be better and we can talk patenting...

I have IR pictures of the ESC, and a copper plate doesn't make any significant difference on the 6oz board... the older 4oz board was a different story. And, a copper pin fin heatsink is actually an easier mod will have much more effect than a copper heat spreader.

BTW -- we are using the temp sensor on the processor -- so make sure any mods you do reduce the temp difference between the FETs and the processor, not the opposite.

What does that mean -- 2 month clean-room run? Are you thinking about getting On Semiconductor to give us some Fab time, or what?
