Optimizing Temperature and Humidity Conditions to Enhance the Reproducibility of Electrostatic Discharge Test Results
To study electrostatic discharge mechanisms,a novel experimental system was developed to simulate the accumulation and dissipation process of electrostatic charge(Chinese patent No.ZL 2023 1 0005367.1).It has been observed that temperature and humidity play an important role during static charge dissipation processes.Within the specified test range outlined in electrostatic discharge test standard IEC 61000-4-2,the dissipation curves for electrostatic charge corresponding to different temperature and humidity levels exhibit notable variations,potentially compromising the repeatability and reproducibility of electrostatic discharge test results.Based on the experimental data and the conclusion confirmed by the previous work that only temperature has a great influence on the maximum breakdown distance,it is recommended to adjust temperature and humidity conditions in order to improve repeatability and reproducibility of electrostatic discharge test results,with a specific recommended range provided.
