Andrew,

We purchase our bare cards in packages of 20 each approximately, with dessicant
inside, and sealed packages.  We open them just prior to use.  That seems to
work best to avoid moisture absorption by the cards.

Hope this helps!

Subject:  [TN] Shelf Life/Storage for Bare PCB




We are in need of establishing some procedures and policies regarding
storage and shelf life of bare printed circuit boards.  Is there any
industry standards regarding storage and/or shelf life for bare printed
circuit boards??
If not, what are some normal practices that are being used by other
electronics manuafacturers??

Thanks for any help.
