FR4 thermal calcs sanity check

I calculated that the temperature difference across a 1" square piece of
1/16 thick FR4 is about 8C/W.

Does that seem reasonable?

TIA,

I meant to include the thermal conductivity that I found at

http://en.wikipedia.org/wiki/FR-4

which gives about .31 W/(m-K).

Sorry for the omission.

That's about right. Vias can help.

Yes. I wanted to start with nothing else considered so I can improve as
I go. Many thanks.
