Careful how you do that! The casings might pop open if the pressure isn't
lowered very gradually.

Anyone out there ever considered dring moisture sensitive devices by
lowering the pressure in a storage vessle?

It is difficult to achieve 40 $B!k (BC and less than 5%RH when ambient RH is 50-60
percent. So, someone called and asked how long he would need to keep the
parts at a pressure equivelent of 80,000 ft above sea level, temperature at
room ambient to dry out parts.

No one here had considered it before. The physics made me feel like I was
at
altitude.
