The four-integrated environmental test chamber adopts the rolling sealing technology and the armature center holding technology to integrate the vibration and mechanical stress test of température and humidity climate stress test with the high altitude low pressure stress test, and becomes a comprehensive stress test System for température, humidity, vibration and low pressure. . When the test System is in operation, température (high température or low température, température change) stress, humidity stress, vibration stress, atmospheric pressure stress, and electrical stress, in a planned combination and periodic space, are simultaneously or separately applied to the sample. Compared with the single stress effect, it has the advantages of more realistic environmental simulation and higher test efficiency. It has been widely used in the assessment of environmental adaptability and reliability of electronic products used in aerospace and spécial vehicles, and is used in the early détection of defects in electronic product design and the screening of pro-cess defects. The vibrating table adopts a fully sealed structure, and the inflation pressure inside the console body can overcome the suction force of the vibrating moving coil and the table body due to the change of the pressure in the test chamber, thereby effectively controlling the moving coil of the vibrating table. The center position ensures that the vibration table works normally.
