ANSI/ESD S20.20 ESD Electrostatic Protection Management System
The ESD electrostatic protection management system is developed based on the revised version of ANSI/ESD S20.20-2021 CN ANSI/ESD S20.20-2014, the American National Standard "Protection of Electrical and Electronic Parts, Devices, and Equipment (excluding Electric Ignition Devices)" of the Electrostatic Discharge Association, and the basic requirements of IEC 61340-5-1_2016 "Electrostatic Protection of Electronic Devices".
ESD stands for Electrostatic Discharge, which refers to the process of releasing energy through discharge when static electricity accumulates to a certain extent. It is a discipline that studies the generation and decay of static electricity, static discharge models, static discharge effects such as current thermal (spark) effects (such as ignition and explosion caused by static electricity), and electromagnetic effects (such as electromagnetic interference).
ESD hazards: can cause harm to human life and health, damage electronic components and devices, thereby affecting product quality, reducing the expected lifespan of electronic components and devices, lowering their reliability, increasing the risk of fire and explosion, and so on.
Introduction to relevant standard associations:
ESDA (Electrostatic Discharge Association of America) was founded in 1982 and is a volunteer association dedicated to promoting the theory and practice of avoiding the hazards of electrostatic discharge. Its members come from over 30 countries. ANSI/ESD S20.20 is an electrostatic protection management system standard established by ESDA, which combines military and industrial experience in protecting ESDS items. It was first published in the ANSI/ESD S20.20-1999 version on August 4, 1999, and was revised on February 11, 2007. The current effective version is the ANSI/ESD S20.20-2014 version, which was revised and published again on June 11, 2014. ANSI (American Standards Institute) is a permanent member of ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission), and a member of IAF (International Accreditation Forum). The International Electrotechnical Commission (IEC) was established in 1906 and is the world's earliest international electrical standardization organization, focusing on international standardization work and qualification assessment management in the field of electrical and electronic engineering. IEC 61340-5-1 is an electrostatic protection management system standard published by IEC. It was first published in the IEC TS61340-5-1:1998 version on December 15, 1998, and underwent revision in the IEC 61340-5-1:2007 version on August 9, 2007. The latest version is the IEC 61340-5-1:2016 version, which was revised and published again on May 27, 2016
The standards and publications of the Electrostatic Discharge Association (ESDA) are for the public interest, namely to eliminate misunderstandings between manufacturers and buyers, provide convenience for product communication and improvement, and assist customers in selecting and obtaining the products they particularly need. This standard covers the necessary requirements for establishing, implementing, and maintaining electrostatic discharge (ESD) control procedures for manufacturing, processing, assembling, installing, transporting, packaging, labeling, servicing, testing, inspecting, or otherwise handling electrical or electronic components, assemblies, and equipment susceptible to damage from human body models (HBMs) greater than or equal to 100 volts and charging equipment models (CDM) greater than or equal to 200 volts.
