ESDA revises S20.20 standard.

The Electrostatic Discharge Association has released a revised ANSI/ESD S20.20 standard. It covers the requirements necessary to design, establish, implement, and maintain an ESD control program to protect electrical or electronic parts, assemblies, and equipment susceptible to ESD from human body model discharges [greater than or equal to]100 V. By 2009, all facility certifications will be based on the latest version.

There are three primary differences in ANSI/ESD S20.20-2007:

* The recommended limits in the 1999 version now are required limits.

* The guidance sections have been removed. Additional information on process design, controls, and materials can be found in TR20.20 ESD Handbook.

* Compliance verification procedures now are specified and can be found in TR53 Compliance Verification of ESD Protective Equipment and Materials.

Both the 1999 and 2007 versions are available for download at
