Anne,

You might be interested in the flex circuit current carrying capacity
software I developed for Rogers some years back available at:

http://www.geocities.com/CapeCanaveral/Launchpad/9641/program/program.html
or at
http://www.rogers-corp.com/cmu/software.htm

While this intended for the thermal properties of flex it does include some
basic calculator functions that might help you with things like voltage
drop.

Good Afternoon Technet,

Does anyone know how thick a trace is required to carry 25 amps in 1 oz
copper?  How about 2 oz copper?  Let's assume it's .062 thick material.
Need help ASAP.  Thanks in advance.
