Just happened to find some relevant material which should probably scale to
25 Amps.
trace width 1mm 2.5mm
35 micron copper 3.0A 6.0A
70 micron copper 5.0A 10.0A
where a 20C temp rise is presumed acceptable - looks like about 2 oz copper
in a 7mm strip should handle 25 A though the table came with a note that
for high current, round wire is preferred.
