Hello, Frank and the group--

The easiest and least expensive method is to use either a strand of
enameled magnet wire
or AWG #30 wirewrap wire to bridge the broken trace.

If possible, solder the repair wire to vias or pads on the ends of the
trace. That's
easier than scraping solder mask from the broken area, tinning the
exposed copper
and bridging the gap with solder or a small strand of wire. Holding the
bridging
wire in place, holding the soldering iron and feeding solder requires
three hands<g>.

If the broken trace handled high currents, use larger-diameter wire.
