ESD Standards: An Annual Progress Report

Industry standards play a major role in providing meaningful metrics and common procedures that allow various manufacturers, customers, and suppliers to communicate from facility to facility around the world. Standards are increasingly important in our global economy. In manufacturing, uniform quality requirements and testing procedures are necessary to make sure that all involved parties are speaking the same language. In electrostatic discharge (ESD) device protection, standard methods have been developed for component ESD stress models to measure a component’s sensitivity to electrostatic discharge from various sources. In ESD control programs, standard test methods for product qualification and periodic evaluation of wrist straps, garments, ionizers, worksurfaces, grounding, flooring, shoes, static dissipative planar materials, shielding bags, packaging, electrical soldering/desoldering hand tools, and flooring/footwear systems have been developed to ensure uniformity around the world.

The EOS/ESD Association, Inc. (ESDA) is dedicated to advancing the theory and practice of ESD protection and avoidance. ESDA is an American National Standards Institute (ANSI) accredited standards developer. The Association’s consensus body is called the standards committee (STDCOM), which has responsibility for the overall development of documents. Volunteers from the industry participate in working groups to develop new and to update current ESDA documents.

ESDA’s standards business unit is charged with keeping pace with the industry demands for increased device and product performance and more effective control programs. The existing standards, standard test methods, standard practices, and technical reports assist in the design and monitoring of the electrostatic protected area (EPA), and also assist in the stress testing of ESD sensitive electronic components. Many of the existing documents relate to controlling electrostatic charge on personnel and stationary work areas. However, with the ever increasing emphasis on automated handling, the need to evaluate and monitor what is occurring inside of process equipment is growing daily. Since automation has become more dominant, the charged device model (CDM) has become the primary cause of ESD failures and, thus, the more urgent concern. Together, the human body model (HBM) and CDM cover the vast majority of ESD events that might occur in a typical factory.

A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part Two

Maxwell’s Equations are eloquently simple yet excruciatingly complex. Their first statement by James Clerk Maxwell in 1864 heralded the beginning of the age of radio and, one could argue, the age of modern electronics.

ESDA’s document categories are:

  • Standard (S): A precise statement of a set of requirements to be satisfied by a material, product, system or process that also specifies the procedures for determining whether each of the requirements is satisfied.
  • Standard Test Method (STM): A definitive procedure for the identification, measurement and evaluation of one or more qualities, characteristics or properties of a material, product, system or process that yield a reproducible test result.
  • Standard Practice (SP): A procedure for performing one or more operations or functions that may or may not yield a test result. Note: if a test result is obtained it may not be reproducible.
  • Technical Report (TR): A collection of technical data or test results published as an informational reference on a specific material, product, system or process.

ESDA’s technology roadmap is compiled by industry experts in IC protection design and test to provide a look into future ESD design and manufacturing challenges. Earlier roadmaps had pointed out that numerous mainstream electronic parts and components would reach assembly factories with a lower level of ESD protection than could have been expected just a few years earlier. Those predictions have proven to be rather accurate. As with any roadmap, the view of the future is constantly changing and requires updating on the basis of technology trend updates, market forces, supply chain evolution, and field return data. An updated roadmap will be published in 2016 looking out to the year 2020. A key prediction from this new roadmap is that while the ESD protection level range may not change dramatically, the distribution of products within this range may change with a change in the mix of companies remaining on today’s traditional technologies while other companies continue to push for technology advancements through the need for higher performance devices.

EOS is an area that has long been overlooked by the industry, not because of any limited importance but rather because of its complex definition and multiple root causes. Indeed, it has proven difficult to find complete agreement among experts on even the fundamental definitions. Thus the language of EOS, EOS threats, and responsibility remains open for discussion. However, a working group is currently completing a TR that focuses on “best practices”, outlining ways to mitigate EOS threats in manufacturing, with an anticipated release in early 2017.

An area of concern that has been growing is the need to define upgraded control processes and tighter limits for high-reliability parts as well as devices that have ESD withstand voltages lower than those specified in the scope of ANSI/ESD S20.20. WG 19 initially was targeting process controls for aerospace only but this has been redirected to consider all high-reliability ESD process control. A document development effort has been initiated to specify “best practices” for high-reliability ESD control processes.

ESDA’s standards committee is continuing several joint document development activities with the JEDEC Solid State Technology Association. Under the memorandum of understanding agreement, the ESDA and JEDEC formed a joint working group for the standardization work in which volunteers from the ESDA and JEDEC member companies can participate. This collaboration between the two organizations has paved the way for the development of harmonized device test methods for both HBM and CDM ESD, which will ultimately reduce uncertainty about test standards among manufacturers and suppliers in the solid state industry. ANSI/ESDA/JEDEC JS-001-2014, a fourth revision of the joint HBM document, was published in September 2014. An update to ANSI/ESDA/JEDEC JS-001-2014 is currently in the works with an anticipated release in late 2016. This new release will introduce a new 50 volt classification level. A second joint working group has completed a joint charged device model (CDM) document. ANSI/ESDA/JEDEC JS-002-2014, the first revision of the joint CDM document, was approved and published in early 2015. These efforts assist manufacturers of devices by providing one test method and specification for each model. These joint documents are aligning the entire ESD community on standardized test methods. In addition, a new joint WG has been formed with a focus on aligning ANSI/ESD S20.20 and JEDEC JESD625B. While in this case not focusing on creating a single joint document, the intent will be to create technically equivalent documents for industry use.

The ESDA is also working in the area of process assessment. ESD TR17.0-01-14 was published in 2016. The TR is a compilation of recent publications by members of the WG. The TR gives the reader examples of “best practices” of process assessment methodologies and test methods. The WG is currently working on a Standard Practice on “Process Assessment Techniques”. The goal of the SP is to provide a set of methodologies, techniques, and tools that can be used by experienced users to characterize the ability of a process to safely handle ESD sensitive items with a given ESD robustness.

The ESDA standard covering the requirements for creating and managing an ESD control program is ANSI/ESD S20.20ESD Association Standard for the Development of an Electrostatic Discharge Control Program for – Protection of Electrical and Electronic Parts, Assemblies and Equipment (Excluding Electrically Initiated Explosive Devices)”. ANSI/ESD S20.20 is a commercial update of and replacement for MIL-STD-1686 and has been adopted by the United States Department of Defense. In addition, the 2016 update of IEC 61340-5-1 edition 1.0 “Electrostatics – Part 5-1: Protection of Electronic Devices from Electrostatic Phenomena General Requirements” is technically equivalent to ANSI/ESD S20.20.

The 2014 updates to ANSI/ESD S20.20 include changes in scope to address CDM and isolated conductors, changes to the qualification of footwear/flooring systems, process required insulators within 1 inch of ESD sensitive devices and requirements on isolated conductors. A section was added on product qualification for clarification. In table 3, there were updates to ionization and the inclusion of wrist strap ground connection requirements and the addition of soldering irons. Formatting of table 3 was updated for clarity. For more information, please go to

An update to ESD TR20.20 has been completed and was published in April 2016. ESD TR20.20 is a handbook providing significant detailed guidance that can be used for developing, implementing, and monitoring an electrostatic discharge control program in accordance with ANSI/ESD S20.20. Additionally, ESD TR53, Compliance Verification, was updated and published in spring 2015. ESD TR53 provides compliance verification test procedures and troubleshooting guidance for ESD protective equipment and materials. Test results may be used for the Compliance Verification Plan Requirements of ANSI/ESD S20.20 or those of the user if more restrictive. Changes to ESD TR53 reflect updates made to the compliance verification plan requirements of ANSI/ESD S20.20-2014.

To better serve the industry world-wide, the ESDA has begun the process of translating documents into other languages, including Simplified Chinese, Traditional Chinese, Korean, Thai, Polish, French, Spanish, and Japanese. ANSI/ESD S20.20-2014 is currently available in all eight languages. Other documents have also been translated or are in various stages of translation. The ESDA has formed a relationship with the China National Institute of Standardization (CNIS) for the translation and marketing of all of the ESDA documents in China. A Memorandum of Understanding has been signed between the two organizations and CNIS is currently working on translation.

In order to meet the global need in the electronics industry for technically sound ESD control programs, the ESDA has established an independent third party certification program. The program is administered by EOS/ESD Association, Inc. through country-accredited ISO9000 certification bodies that have met the requirements of this program. The facility certification program evaluates a facility’s ESD program to ensure that the basic requirements from industry standards ANSI/ESD S20.20 or IEC 61340-5-1 are being followed. More than 777 facilities have been certified worldwide since inception of the program. The factory certification bodies report strong interest in certification to ANSI/ESD S20.20, and consultants in this area report that inquiries for assistance remain at a very high level. Individual education also seems of interest once again as 95 professionals have obtained certified ESD program manager status and many more are attempting to qualify for this certification. A large percentage of the certification program requirements are based on standards and the other related documents produced by the ESD Association standards committee.
