We posted this back in May 2012, and we noticed the video has gone viral recently with major news channels like CBS news. People do not start feeling charges from an ESD event until the discharge is at least 2000 volts while many common components used for manufacturing of electronics are susceptible to 100 volts or less . …
HUMAN BODY MODEL The updated standard ANSI/ESDA/JEDEC JS-001-2011, For Electrostatic Discharge Sensitivity Testing Human Body Model (HBM) – Component Level Table 3 has divided the Class 0 classification into two withstand voltage levels with class 0A being less than 125 volt sensitivity, and class 0B being 125 to less than 250 volts. If handling class…
Seeing ElectroStatic Discharge (ESD) damage is basically impossible. Damage to semiconductor device structure is NOT visible at ordinary magnifications of an optical microscope. If the microscope is capable of 1000X-1500X magnifications, you just might be able to “see” something. The method used, only occasionally as there is considerable expense, is by delayering and etch enhancement…
Most people do not start feeling the effect of an ESD event until the discharge is at least 2000 volts. It typically takes a ESD discharge of greater than 2,000 or 3,000 volts for a person to feel the “zap”. The number varies because the sensitivity of people is different and measuring the voltage is imprecise, so…
People do not start feeling charges from an ESD event until the discharge is at least 2000 volts while many common components used for manufacturing of electronics are susceptible to 100 volts or less . Here are some other common activities that will generate an ESD charge: – Walking across a carpeted floor: 1,500 – 35,000 volts –…
Lots of end users tell us that rarely, if ever do they connect an ESD event to a failed product. But almost always, end users are not willing to invest the time in investigating the root cause of their product failure to determine if it was an ESD event or not. Most of the time…
ElectroStatic Discharge (ESD) is the hidden enemy within your factory. You cannot feel or see most ESD events but they can cause electronic components to fail or cause mysterious and annoying problems. There are two types of ESD damage: 1) Catastrophic failures, and 2) Latent defects. By definition, normal quality control inspections are able to…
