What is the detrimental effects over different periods of time on the 
solderability of HASL PCBs due to uncontrolled humidity and temperature.
I have seen 5/10 Micron plating reduced to 0.8 Micron due to bad storeage.
What is the effects of different humidity and temperatures on the stored 
PCBs after different lengths of time?
Has  there been any research into this?
Any suggestions/opinions appreciated.

Thanks in advance.
