A cold and hot impact box is a device used to test the durability of electronic products in environments with drastic temperature changes. It can simulate the use of electronic products in extreme temperature environments, thereby evaluating the reliability and durability of electronic products. The cold and hot impact chamber usually consists of two independent testing chambers, one for high-temperature testing and the other for low-temperature testing. These two testing rooms are connected by a rotatable test stand, allowing electronic products to quickly transition between high and low temperatures. This article will discuss the use and maintenance methods of cold and hot impact boxes. View >>
