The following files show the two sides of a PCB in a professional
weather station. This shows four dark areas which the manufacturer has
ascribed to water penetration. These are centred on a hole. The whole
thing seems funny to me, as it has happened on only a few of the holes.
I understand that it was housed in a water-tight case, not very far from
the Pacific coast. I was not able to ascertain the laminate type, but it
would not surpise me if it were paper based (FR3?).

Has anyone seen anything like this?

Brian
