I recently picked up a Williams Phoenix and knew that it had some battery damage on the MPU board. I have a little experience working on boards and would like to learn more about board repair through these projects.
I've removed the battery holder which was attached to the board with short lengths of wire. When the holder was removed, it was apparent that a few of the wires attached to the boards had corrosion. The one negative connector came off as it was the most corroded. I cleaned the board of the corrosion front and back using instructions on flippers.com.
Below are 2 pictures - front and back. I'm assuming that I should detach the wires (as shown below) by heating up the solder that are on the board. My question is that once I remove the wires, is it just a matter of re-soldering the wires to the connections on the board? Should I de-solder the wires and clean it again to make sure?
I appreciate the help.
