JESD22-A110: specifies the HAST test with bias voltage (BHAST), which simulates the moisture resistance of analog devices in actual working conditions.
JESD22-A118: specifies the HAST test (UHAST) without bias voltage to evaluate the moisture resistance performance of the packaging material itself.
JESD22-A102: High Pressure Steaming Test (PCT) is an extreme acceleration test that is saturated (100% RH).
AEC-Q100/Q101 automotive grade chip reliability certification standard explicitly references the mandatory certification requirements in the automotive electronics field under the HAST testing conditions.
IEC 60068-2-66 general standard, which is the same as the GB/T 2423.40 standard, is the basic environmental testing method for electrical and electronic products.
