warehouse storage ...  Big unknowns when it could have been packed in a

Fair weather and calm winds!

Yes, I know that, have been analyzing a lot during the years, but this seems
a little different. Note: 1. the   unit has never been exposed to any other
environment than inhouse atmosphere.
2. The screw is not in contact with anything else than copperless FR-4.
3. Only one screw has this corrosion.
