A simple sealed oven (at 40C) that is purged with clean nitrogen is very
effective (clean N does not carry H20)at getting rid of moisture and rather
inexpensive.

Subject: [TN] Moisture Sensitive Components


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

It is difficult to achieve 40°C 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.
