Step 21Testing the board for short circuits
After the traces are cut apart it is essential to test that there are no connections between adjacent areas.
You may use a 12V lamp connected to the same supply as used for electrolysis for testing. Or the way I do it - use a 12V, 15A supply together with a car headlamp for indication. Small shorts that used to be there get vapourised, and if that lamp lights up, boy, that really IS a short circuit.
For clearing the short circuits just run the sharp point of a knife through the lines. Angle it one way in one pass, and the other way in the next pass, and any copper still in there will just lift and crumble away.
