Thank you for the information. The board is currently drying with a "wick" made of kitchen towel paper. I live in Crete, Greece so I guess it is not possible to send the board to Eva Holiman (very interesting link). But I will try to dry the board as much as possible during august. I estimate that about 80% of the moisture will be out of there in a couple of days. After that I will run all the leaking tests you suggested.
