Questions And Answers

You are correct as the information is very similar with only a few differences. JESD 625A [was EIA 625] is fine, but since ANSI/ESD S20.20 has the American National Standards Institute designation, we recommend using ANSI/ESD S20.20 for developing your ESD control program.  Also, IEC TR 61340-5-1 is primarily used in Europe.

ANSI/ESD S20.20-1999 which has since been updated to ANSI/ESD S20.20-2007 can be downloaded at no charge from www.ESDA.org.

In 2000 Dave Swenson wrote “In 1990, the industry had no ESD-related handling practice documents that enjoyed widespread acceptance. In the ensuing 10 years, various groups developed such handling practices, which are gaining in acceptance. Readers should become familiar with three documents that will affect the industry for many years. These documents are

• JESD 625A (update of EIA 625; see http://www.jedec.org).
• IEC TR 61340-5-1 (will replace EN 100015).
• ANSI/ESD S20.20 (commercial version of MIL-STD 1686; see http://www.esda.org).

Each document contains tables that list almost every conceivable static control product or material along with a suggested range of performance suited for the intended application. The specifications for static control products and materials involve an electrical property or a physical characteristic that imparts a static control property.”
