    Since I don't care how a board looks, only that it works well, I will often run a jumper wire to replace the entire trace if it is messed up.By replacing the entire trace I am able to start and end at a larger junction point and get a better solder job.

    But in your situation I would not do that since I would not want to put any unnecessary heat into that chip that is soldered to the board, so I would just repair the trace and not put a jumper wire near that chip's leg.

    The repair job in the picture is not a hard repair to do, but it looks like thing are not cleaned up on your board. Heat up and remove all of the excess solder and original repair work in that area and start again.

    I would place a jumper wire in a way so the you are not trying to solder both jumper wires to the different traces in the same area, I hope that makes sense. Take advantage of the green resist coating to prevent your solder from flowing to the wrong trace.

    Also, make sure you are using good quality resin core solder and a small temperature controlled soldering iron. I think many people fail because they try to use solder that is a huge diameter for the job and/or a soldering iron that is huge for the job. Take a look on this forum for threads on this topic if you are unsure about what you should be using. When you have the correct tools (which are not expensive) this type of repair work is a treat to do.
