Dear PWB designers,

I thought you'd be interested in the thermal resistance vs. copper area graphs
from IRF:
  "Maximizing the Effectiveness of Your SMD Assemblies: IR Application Note
AN-994"
  http://www.irf.com/technical-info/an994/an-994.htm
  http://www.irf.com/technical-info/an994/an-994p4.htm
has graphs that show that single-sided 2 oz copper boards have superior thermal
characteristics than double-sided 1 oz copper boards. Interpolating from the
graphs, it appears that single-sided 3 oz. copper is superior to double-sided 2
oz copper.

Hello, did the rest of the article ever turn up?
If not let me know and I'll post it as I once downloaded it all.
