Most commercial and consumer products are tested and verified in non-condensing humidity environments, which verifies the ability to withstand operating in ambient atmosphere with a high moisture content. Military and Aerospace products however, are often required to operate in a climatic testing environment where moisture will condense in liquid form directly on the product. This is NOT a test you want to immediately run with out doing some pre-test work. For one thing, a product has to be designed to withstand this very severe environment. (How to do this could be the subject of another post.) If you "think" your design is good, now go on to some "pre-checks". Start by examining all of your conformal coated electronics, in detail under a UV light. Look for small voids. If you have …
