ZT-4022 High Pressure Accelerated Aging Test Chamber
The high-pressure accelerated aging test chamber is mainly used to evaluate the reliability of products or materials in humid environments. This is achieved by setting and creating various conditions of temperature, humidity, and pressure in a highly controlled pressure vessel, which accelerates the penetration of moisture through external protective plastic packaging and applies these stress conditions to the mold/device. High acceleration stress testing has become a necessary test in many industries, especially in semiconductors, solar energy, and other industries, as a fast and effective alternative to standard temperature and humidity deviation testing (85C/85% RH-1000 hours).
