Moisture Damage Electronics
If a device is moved from a cool environment to one that is warm and humid, circuit boards may become coated in moisture. ... Also important is protecting electronics from low humidity environments, which can lead to static electricity discharge that results in irreversible damage to components.
Different Humidity Level Damage Electronics
Brittleness can occur at humidity levels as low as 40 percent, while mildew grows atlevels over 50 percent RH. The range recommended by experts is between 30 and 50 percent RH, and temperatures no higher than 70 degrees Fahrenheit. Similarly to books, electronics are sensitive to extremes of humidity.
Sources of Water Contamination in a closed container or package
Water vapor in the air inside the package;
Moisture contained in the materials inside the package;
Moisture in or on the walls of the package; and
Entry of moisture into the package due to permeation or leakage
