While I certainly do not recommend this practice, I had some boards in my
desk for 5 years, under some papers, beneath a box...I had 'forgotten' they
were there, just for kicks I soldered them without bake and they looked
good.

For storage in an office (or controlled)environment I would suggest vacuum
seal with dessicant for the environment you suggest. Time in itself for that
period should not be an issue, just keep them sealed and they may last up to
7 years or more.

Subject: [TN] PCB Storage

Hi All,

I have some bare PC boards that may be built up in the future, but not in
the near future. I would like to put them into storage until needed
(anywhere from 6 months to 2 years). The boards are .062" FR-4 HASL boards.
What would you recommend  for protection, assuming that the storage
conditions are typical of an office environment? Would I have to do anything
special to them when they are removed from storage? Any suggestions would be
greatly appreciated.

Thank you,
Paul Black
