RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Electrostatic discharge is a primary concern for electronic assemblies from the integrated circuit level right up to the end product. Much science and engineering has gone into developing protection circuitry and handling techniques to reduce the likelihood of damage by ESD. A vital aspect of electrostatic discharge susceptibility is related to shielding of the microcircuits that have increasingly small gate widths and dielectric thicknesses. Huge amounts of resources have been invested in mitigating the effects of ESD. One part of the solution is to adequately shied the circuitry that does not have direct exposure to the outside world. Part of the qualification for ESD ruggedness of a final product is to zap (that's actually a technical term) the chassis in multiple locations to be sure there are no breaches in shielding that will permit a discharge path inside.
