The trace-width depends on TWO things: How much CURRENT ("amps") the trace
must conduct, and how SKILLED you are in making a trace. 0.01" is found on
professional PTH boards!

0.05" wide traces are "healthy", and easy to do "manual" work. 0.125" is
quite wide, actually! You could pass three or four amps through a 1/8" wide
trace with no problem. I forget the site, now, where it describes how to
calculate a trace-width based upon current to flow through it. Someone else
remember it?
