JESD22-A101D.01-2021 is a standard developed by JEDEC (Joint Electron Device Engineering Council) on the life test of steady-state temperature and humidity deviation. Sanwood's Temperature and Humidity Test Chambers are technically capable of meeting the JESD22-A101D.01-2021 test standard.
JESD22-A101D.01-2021 standard overview
This standard specifies the determination methods and conditions for performing steady-state temperature-humidity deviation life tests. The test is primarily used to assess the reliability of unsealed mounted solid state devices in humid environments by simulating high temperature and high humidity ambient conditions, accelerating the penetration of moisture through the external protective material or along the interface between the external protective coating and the conductor, or through other features of it, and thereby assessing the humidity resistance of the insulating material used in the component.
JESD22-A101D.01-2021 requirements for testing
Temperature: 85±2°C (wet ball 81°C) and a pressure of 49.1 kPa (7.12 psia), but wet ball temperature and pressure are not mandatory.
Humidity: Relative humidity is not specified, but is normally maintained at a high level to accelerate water penetration in this type of test.
Warming and humidification: To be completed within 3 hours, while avoiding condensation, it is common practice to warm up the temperature first, then the humidity.
Cooling down the humidity: to be completed within 3 hours, while avoiding condensation, the process of maintaining the dry bulb temperature is always higher than the wet bulb temperature, the usual practice is to first reduce the humidity, and then reduce the temperature.

Advantages of Temperature and Humidity Test Chamber of Sanwood Technology
Sanwood Technology Temperature and Humidity Test Chamber in addition to meet the technical requirements of JESD22-A101D.01-2021 test standards also has the following product advantages:
1, Qualitiable appearance, small volume and large capacity, suitable for laboratory testing of small test items, stable technical indicators, more reliable operation.
2, Multiple protection devices, no fuse switch, fuse, over-temperature protection, anti-dry burning protection, water shortage protection, liquid level protection, compressor overpressure, overheating, overcurrent protection, emergency stop and other protection devices, so that the test is more safe and reliable.
3, using PID + PWM principle of VRF (refrigerant flow control) technology to achieve low-temperature energy-saving operation (electronic expansion valve according to the thermal conditions of refrigerant flow servo control technology) low-temperature working conditions, the heater does not participate in the work. This way in low-temperature conditions, can achieve 30% reduction in energy consumption.
Sanwood's Temperature and Humidity Test Chamber is a reliable environmental simulation test equipment, in the set time to simulate the formation of a variety of harsh climatic conditions, can be predicted under normal conditions of durability testing.
