The September issue of In Compliance concentrates on ESD and Static Control.
Toward Standardization of Low Impedance Contact CDM
By Nathan Jack, Brett Carn, and Josh Morris
The 16.6 ohm implementation of contact CDM (LICCDM) recently published in ANSI-ESD Standard Practice 5.3.3 is shown to produce waveforms of similar shape, Ifail, and Ipeak vs. Ceff dependency as JS-002. The non-monotonicity of JS-002 at low voltages is overcome using LICCDM. A path to joint standardization with air discharge testing is proposed.
Static Control Flooring in High Reliability Environments
By Tom Ricciardelli
High reliability organizations (HROs) typically implement stringent static control programs to mitigate the risks of catastrophic and/or life-threatening failures. This article describes some of the considerations to consider for static control flooring in these more demanding environments.
By Vladimir Kraz
Grounding is often viewed from separate points of view - safety, ESD, or EMI. This article combines all these aspects together so that practitioners can address grounding at the factories and in the laboratories in a comprehensive way.
Caster Contact: The Achilles Heel of ESD Floors
By David Long
A fully functional ESD floor prevents static generation and provides an effective path to ground for personnel and equipment. Many conductive and dissipative floors meet STM 7.1 resistance parameters in ANSI/ESD S20.20 but fail to provide adequate electrical contact for grounding equipment with conductive casters and drag chains.
