A Faraday cage or Faraday shield is an enclosure formed by conducting material or by a mesh of such material. Such an enclosure blocks external static and non-static electric fields. Faraday cages are named after the English scientist Michael Faraday, who invented them in 1836. An impressive demonstration of the Faraday cage effect is that…

Chino, CA — Desco’s Wescorp brand ESD Hi Temp Polyimide Tape is a low-charging tape that can be exposed to high temperature applications such as wave soldering. The polyimide film is 1.0 mil thick (0.001″ or 0.0254 mm), and will not leave a residue when removed. The tape generates less than 50V (at 73°F, 45…
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…
…with Electrostatic Discharge (ESD) Follow Live Dec 24: Los Alamos National Lab Tracks Rudolph’s Nose, Santa’s Sleigh
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…
> by Rick Cardinale, Bird Electronic Bird Electronic, founded in 1942 by J. Raymond Bird, soon became a leader in radio frequency instrumentation. Today, Bird also has moved into digital instrumentation test equipment. With the development of digital instrumentation came the increased need for controls to prevent ESD events. Improving ESD protection has been an…
