A dew test, for example, can be used to test paints and other surface coatings. Electronic assemblies can exhibit migration behavior with live components, which can lead to failure symptoms due to the reduction in insulation.
Certain plastics absorb water in moist heat and can thus change their shape.
Electronics embedded in films can cause failures due to the diffusion of water. Examples here are the infiltration of CD coatings or the destruction of OLEDs.
In combination with different scenarios of a humidity change test, time lapses can be realized to determine the lifetime of your products.
