ESD

 Most people notice a difference in the ability to generate static electricity when the air gets dryer (the % RH decreases). As an example, walking across a carpet can yield a charge of 35kV at 10% RH [very dry air], but will drop significantly to 7.5kV at 55% RH. In an electronics manufacturing environment lower…

Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown. The natural phenomena of ESD has been occurring for as long as our planet has been around and apparently it has been a problem for much of that time.  A recent post…

The Made by Monkeys blog on the Design News website recently posted an article called ZAP! Another ESD Casualty about an electrical engineer’s experiences with electrostatic discharge (ESD). The article offers a perspective on ESD control from “then” compared to now. Not much has changed. ESD is a natural occurring event that can damage ESD…

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  .  …

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…

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 –…
