attached are photos of some water damage on a circuit. it is from a lighting board for a special sensory device from a school for children with Cerebral Palsy. I have cleaned the circuit board and removed the corrosion. ohm tested all the circuits I could find that were corroded. found one with an open circuit. I am not familiar with the best way to repair this. I am looking for as cheap as possible since I am doing this as a favor to the school, but I also want it to be right. could I run a wire from pin to pin? also there is a chip on the opposite side of the board I'm wondering if that chip could have been damaged (short circuit) by the water also. there was no corrosion on the side with the chip but could it have been damaged by the short on the other side? (you can see were the chip was in the overall photo that it is missing on the upper left side)any way to check this? I have a multi meter and some common knowledge of circuits. feel free to ask questions or offer advice.
