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.
