After reading Bev's great discussion, I decided to put some numbers on
the moisture vs. temperature vs. relative humidity. From a SI
psychrometric chart, I put together the following summary table of
moisture content (g water vapor / kg dry air):
% Rel | Temperature |
Humidity | 25C | 10C | 5C |
---------+-------+-------+-------+
90% | 18 | 7 | 5 |
---------+-------+-------+-------+
50% | 10 | 4 | 2.5 |
---------+-------+-------+-------+
As Bev pointed out, an air-conditioned storage room (lower temperature
and humidity) can do wonders.
Be careful at assembly, low humidity is BAD for ESD!
