hi Allan,
for current carrying capabilities, please follow the URL:
http://www.ultracad.com/using_ipc_temp_charts.pdf
The inner and outer layer current capabilites of traces already got a
mention on silist which you can find at:
//www.freelists.org/archives/si-list/07-2002/
and check for replies from john barnes and Goug brooks.
i hope experts can throw more light.
Regards
Rakesh
