Always store on a flat surface.

Suggestions are: * Procure solderable finishes that have sufficient thickness to avoid intermetallic problems and use storage conditions that do not promote oxide growth problems. * Bagging/sealing boards has been shown to extend storage durations in some cases. * Keep boards in a 75 +/-10F, 30-60% RH controlled atmophere. Focus your efforts on a bare board storage area that is dry and don't spend time (and $$) on trying to keep things cold. [Recognize that proper ESD control measures in the assembly area want higher, rather than lower humidity level.]
