How Fast Does a Charge Decay?

Associate Professor Neils Jonassen authored a bi-monthly static column that appeared in Compliance Engineering Magazine. The series explored charging, ionization, explosions, and other ESD related topics. The ESD Association, working with In Compliance Magazine is re-publishing this series as the articles offer timeless insight into the field of electrostatics. Professor Jonassen was a member of [...]

The Silent Killer: Suspect/Counterfeit Items and Packaging

Over the past several years, U.S. based organizations have curtailed traditional internal verification efforts due to reliance on contract manufacturers, distributors and suppliers to do the right thing. The inspection of ESD sensitive parts is very important, but without special safeguards, the additional handling to remove and repack a product for validation can cause both [...]

ESD Influence on ICs

New developments in electronics manufacturing are increasingly dominated by the requirements of EMC today. Considerable follow-up costs in product development are caused due to the failure of electronic modules in EMC compliance tests. The integrated circuits that are used in an electronic system are critical for its EMC performance as a whole. ICs are often [...]

Fundamentals of Electrostatic Discharge – Part Five: Device Sensitivity and Testing

The models and test procedures used to characterize, determine, and classify the sensitivity of components to ESD.

A Wreck of an Airplane

The C-47 Skytrain banked sharply left and the runway came into view, a slash in the thick evergreens. Cresting the top of the ridge, the pilot pulled the power back on the twin engines and set the flaps at twenty degrees. The plane rose slightly with the added lift until the airspeed dropped and the [...]

Characteristics of Air as an Insulator

A few months ago, we built a clear plastic box containing a four-inch square steel plane, a two-inch diameter steel sphere, and a micrometer drive to precisely adjust the distance between the plane and the sphere. Recently, we finally had the time to do some testing. We set the distance to a known value and [...]

I’m Partial to Partial Inductance!

It is well known (but often forgotten) that the concept of inductance, without defining a complete loop of current, is completely meaningless! Some books give inductance of a length or wire, some people talk about the inductance of a via, and still others talk about the inductance of ground braids, etc. All these discussions about [...]
