Hi, and welcome to AAC.

This looks nasty. It will not be easy to repair. One thing you could try, is to gently wipe the traces with Acetone, and solder on thin enameled copper wires. The wires need to be coated, or they will short when they come in contact with each other. You need steady hands, a thin solderiron tip, and a good eye.

If you mean the width if the traces with pitch, i think it is 8mils or 6 mils. Just guessing.

If you solder anything wrong, or get a solderblob, you could damage the whole thing. Be warned, and good luck.

In addition to the obvious corrosion, often liquid spills damage vias as well. If that's a small front panel board, it may be better to try getting a replacement. With some brands this is not too difficult or expensive.
