FC261: Electrical Fields – Practical Considerations for the Factory
June 14, 2018 8:30 a.m. – 12:00 p.m.David E. Swenson, A nity Static Control LLC
ANSI/ESD S20.20 recommends that process essential insulators with a measured electrical eldstrength of >2000 volts at 1 inch should be kept a minimum of 12 inches from ESD susceptibleitems. In addition, for close proximity or contact, the standard requires that insulators have anelectric eld of <125 volts at 1 inch. Just what are the practical considerations of this statement?What is the size of a charged object that imposes a risk? The goal of this tutorial is to show, bydemonstration, the eld strength and resulting induction ability from di erent sized objects. Theaudience should gain a practical perspective of size and distance as related to electrical elds andinduction and be able to relate the information to their own factory situations.
Practical Applications of Ionization

Ionization is a powerful tool in the toolbox of an ESD control practitioner. Our half-day tutorial,“Ionization Issues and Answers for the Program Manager” goes into depth about the physics
of ionization, and general applications. This tutorial builds on the fundamentals and providesadded information about applications of ionization that go beyond those mentioned in the originaltutorial. The introduction part of this tutorial begins with a review of the physics of ionizationbefore entering the discussion of applications. Ionization is used in a wide variety of industrialapplications to reduce charge on plastic and paper lms, extrusion processes, pharmaceutical andother powders, petrochemical processing, printing and graphic arts, as well as the wide variety ofelectronic component and equipment production processes. Numerous demonstrations will helpdemonstrate the power of ionization to reduce charges on materials. In addition, it is necessary tounderstand the limitations of ionization and recognize where it is useful and where it is not.
