How do you Repair a Cut Trace?

Drop of solder usually does it for little nicks.

you can also trace the trace back and connect a jumper between what it connects. for example if it connects to pin two of some chip and pin 8 of another just connect a wire between those two pins.

this isn't always easy or possible but if it is it can be much easier than solder.

...but if you want it to actually work reliably, even after such a jumper you should solder the ends.
