a second thought...hmm do you mean, through the copper ?? dont hope so :)
but I had a job where it was custom to store the boards in a refigerator
as the door was standing open in summer, there had come water on the boards..they did not work and they were new.. so from this, I think that moisture can get through the cover and maybe the humidity in air is the worst problem with storage.. not light-or temperatur differences ..but it was mainly the part had had water on the cover that was realy bad.
