ACCELERATED MOISTURE RESISTANCE - UNBIASED AUTOCLAVEStatus: Reaffirmed January 2021
This test allows the user to evaluate the moisture resistance of nonhermetic packaged solid state devices. The Unbiased Autoclave Test is performed to evaluate the moisture resistance integrity of non-hermetic packaged solid state devices using moisture condensing or moisture saturated steam environments. It is a highly accelerated test that employs conditions of pressure, humidity and temperature under condensing conditions to accelerate moisture penetration through the external protective material (encapsulant or seal) or along the interface between the external protective material and the metallic conductors passing through it. This test is used to identify failure mechanisms internal to the package and is destructive.
