Machine introduction:
Programmable 3- Zone Temperature Cycling Cool and Heat Thermal Shock Testing Chamber for Electronic Products makes the product under low and high temperature, and accelerates the failure caused by repeated temperature changes under normal operating conditions of items.During cold and hot shock tests, the transition between extreme temperatures was very rapid, exceeding 15℃ per minute.Alternatively, the temperature cycle uses a slower rate of high and low temperature change, exceeding 5℃ per minute.
