Hot and humid test

 Hot and humid environment generally exists in the whole life cycle of the transportation, storage and use of electronic products. Under the influence of hot and humid environment, the insulation materials and metal surfaces in electronic products will adsorb water vapor, leading to the degradation of products.

At the same time, under the joint action of humidity, temperature and electrical stress, it will cause electrochemical reaction and metal corrosion, resulting in the insulation resistance of electronic equipment, leakage increase, serious flying arc, breakdown circuit damage and other phenomena.

What is the hot and humid test

Hot and humid test can be divided into constant hot and humid test , alternating hot and humid test, is the environmental stress of temperature stress and humidity stress two environmental stress, need to use constant hot and humid test chamber or alternating hot and humid test chamber, effect of typical environment is mainly caused by the moisture of the surface and interior of the product.

On the one hand, the hot and humid test can simulate the impact of the hot and humid environment on the actual use of the product, on the other hand, it can also identify the moisture-proof ability of the product, and evaluate the safety and reliability of the product under high temperature and high humidity conditions.
