Hello,

Try to get a hold of IPC-2221 specs (Generic Standards on Printed Board
Design).  Page 38 gives you 3 graphs showing conductor thicknesses, widths
for internal & external layers and their current carrying capacity.  Page 39
will show you minimum spacing requirements between conductors at various
voltages.

Hope this helps.
