The temperature, humidity and vibration comprehensive stress test system (three comprehensive test chambers) integrates temperature, humidity and climate stress tests with vibration and other mechanical stress tests. When the test system is working, (high temperature or low temperature, temperature change) stress, temperature stress, vibration stress and electrical stress are applied to the sample simultaneously or separately in a prescribed combination and periodic space. Compared with a single stress effect, it has With the advantages of more realistic environmental simulation and higher test efficiency, it has been widely used in the assessment and evaluation of the environmental adaptability and operational reliability of electronic products such as aerospace, ships, and automobiles, and in the early detection of design defects and process defects in electronic products. screening occasions.
