Low pressure test of electrical and electronic products

Low pressure test of electrical and electronic products-Physical Performance Testing-

Test Background

The reason why electronic and electrical products need to be tested at low pressure is because due to the reduction of atmospheric pressure, the mechanical and electrical properties of electrical and electronic products will be greatly affected, sometimes leading to product damage. For example, the heat dissipation conditions of electrical and electronic products are different from normal atmospheric conditions. It can be seen that under low pressure conditions, the proportion of radiation heat dissipation increases and the proportion of convection heat dissipation decreases. In addition, due to the reduction in atmospheric density, the medium conditions surrounding the heat dissipation product will also change.
The impact of low air pressure on electrical and electronic products cannot be simulated under normal atmospheric conditions, so low air pressure tests must be conducted. The purpose of low-pressure testing of electronic and electrical products is to determine the suitability of components, equipment or other products for storage, transportation or use under low-pressure conditions.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various electrical and electronic products, and provides professional low-pressure testing and other services for electrical and electronic products.
