Subject: 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
