The shelf life of OSP boards is 6 months in vacuum sealed packs.You
can store these boards from a RH ranging from 30% to 70% without any
deterioration in the shelf life as long as vacuum seal is intact

What is the shelf life of Copper bare boards with OSP finish.
What is the nominal RH at which the board may be stored at.
If it's 45% RH, what's the effect  if environment RH is increased to
60%
ie what effect will an increase of RH have on the PWB during
storeage?
Thanks in advance.
