Try http://www.ultracad.com/calc.htm  and download "wiregage.exe".  Lots of
other good calculators on this site.  I have a brute-force formula too if
you're interested, but the Ultra-Cad calculator is much handier.

Does anybody knows a good link or freeware for DC resistive calculation in
function with the thickness, width and length of a PCB track. I already
know
about "trace with calculator"
http://www.aracnet.com/cgi-usr/gpatrick/trace.pl but this is not exactly
what I'm looking for, current and temperature rises aren't the issues for
my
application. It's more a question of DC equivalent resistive for a coil
made
with a long PCB trace.
Thanks
GF
