The multi-door high temperature aging test box is a non-destructive test for the full inspection of automobile dashboards and lights. Its purpose is to select products with certain characteristics or to eliminate products with early failure, so as to improve the reliability of products. During the manufacturing process of the product, some products have so-called early defects or failures due to material defects or out-of-control processes. If these defects or failures can be eliminated early, the reliability level of the product in actual use can be guaranteed. This test The box can provide a detection method for automatic detection of independent temperature control intervals, which greatly improves the test efficiency.
