防静电屏蔽包装袋测试方法研究

列举了目前市场上针对防静电屏蔽包装袋的表面电阻测试方法和静电感应峰值电压测试方法,并根据其各自的测试原理说明了其缺陷,对美标提出的静电放电感应能量法进行了详细的分析,其特点是使用接近实际环境的HBM模型,用不影响测量回路的电流探针取代电压探针,用200MHz带宽500MS/s采样率示波器覆盖更宽的频率范围减小误差,从能量的角度表述了静电屏蔽性能的优劣。

Research of ESD Shield Package Measurement

The test methods of the surface resistance and the electrostatic inductive peak voltage of anti-electrostatic shielding bags are introduced.The characteristics of these methods are summarized.Inductive energy method from America standard is fully analysed.The advantages of anti-electrostatic shielding bag inductive energy test method are listed which using HBM model and current probe and a digital storage oscilloscope capable of a 200MHz single short bandwidth and minimum sampling rate of 500M samples per second to reduce the test errors.
