ESD人体模型(HBM)与IEC IEC61000-4-2标准白皮书California Micro DevicesWhite PaperJanuary2008Human Body Model(HBM)vs.IEC IEC61000-4-2OverviewMany ESD standards such as the Human Body Model(HBM),Machine Model(MM),Charged Device Model(CDM),and IEC61000-4-2have been developed to test for robustness and ensure ESD protection.Unfortunately,thesestandards are often misunderstood and sometimes used interchangeably,which can result in tested,“protected”systems that later fail in the consumer’s hands.To ensure better product reliability,it is critical that today’s designengineer understand the significant differences between manufacturing environment and system end user environmentESD testing.While most designers are familiar with the classic device level manufacturing tests that are applied to integrated circuit
