The thermal shock testing machine is used to test the degree to which material structures or composite materials can withstand continuous environments of extremely high and low temperatures in an instant, in order to test the chemical changes or physical damage caused by thermal expansion and contraction in a short period of time Applicable objects include metal, plastic, rubber, electronics Waiting for materials can serve as a basis or reference for product improvement
In order to simulate different electronic components and the temperature conditions encountered in actual use environments, changing the temperature difference range and rapid temperature changes can provide a more rigorous testing environment, shorten testing time, and reduce testing costs. However, it is necessary to pay attention to the potential additional impact on material testing and the occurrence of non use state destructive tests. The RAMP test conditions are indicated as: Temperature Cycling or Temperature Cycling Test, which refers to temperature cycling (temperature shock with controllable slope), while the failure mechanism remains unaffected.
