I have a tiny PCB that I've been working on and off of for a while now. I received it with leaking batteries, and it had corroded some of the traces off the board. Most recently, I tried redrawing the burnt traces with conductive paint, but to no avail. I actually popped batteries in it last night and had activity for the first time ever, though it was short. I then scraped off the paint and decided it might be time to try a jumper wire. My question is: there used to be a trace pad that completely came off the board, do I need to worry about that? Is it possible to skip the pad entirely and make a bridge between the two sections of trace?

I'm familiar with soldering, but not with specifically making a jumper wire. Mostly I'm trying to find the right kind of wire to do it with and where to purchase it.
