Yup, electronics tech here and we have to bake our boards to remove moisture from the mid-layers before conformal coating them. We do boards which go through pretty harsh conditions so moisture trapped in the boards could cause massive issues at sub zero temperature and swelling from evaporating liquids cause issues at high temperatures.
Less of a concern for consumer tech but can be a huge concern at industry levels.
Causes corrosion.
Causes circuit boards to swell and deform.
