ESD Industry Standards (2022)

The electronics industry is continually shifting. Device circuitry density and technology are more complex, and electronics manufacturing is more heavily reliant on out-sourcing. As ESDS items are becoming more sensitive, ESD Control Programs have mushroomed. The early history belief of “smoke and mirrors,” “magic,” and lofty claims of performance is rapidly being relegated to the past.

Today, more than ever, meeting the complex challenge of reducing ESD losses requires more than reliance on faith alone. Users require a way to legitimately evaluate and compare competing brands and types of products and ESD protection strategies. They need objective confirmation that their ESD Control Program provides effective solutions to their unique ESD problems. Contract manufacturers and OEM’s require mutually agreed-upon ESD Control Programs that reduce duplication of process controls.

That is where standards come into play. They provide information in developing programs that effectively address ESD process control. They help define the sensitivity of the products manufactured and used. They help define the performance requirements for various ESD control materials, instruments, and tools. Standards are playing an ever-increasing role in reducing marketplace confusion in the manufacture, evaluation, and selection of ESD control products and programs.

Who uses ESD standards? Manufacturers and users of ESD sensitive (ESDS) items, manufacturers and distributors of ESD control products, certification registrars, and third-party testers of ESD control products.

Why use ESD standards? They help assure consistency of ESDS items and consistency of ESD control products and services. They provide a means of objective evaluation and comparison among competitive ESD control products. They help reduce conflicts between users and suppliers of ESD control products. They help in developing, implementing, auditing, and certifying ESD control programs. And, they help reduce confusion in the marketplace.

In the United States, the use of standards is voluntary, although their use can be written into contracts or purchasing agreements between buyer and seller. In most of the rest of the world, the use of standards, where they exist, is compulsory.

In the early 1980s, there were relatively few reliable ESD standards and few ESD standards development organizations. Today’s ESD standards landscape is not only witnessing an increase in the number of standards but also increasing cooperation among the organizations that develop them.

Today’s standards fall into three main groups. First, there are those that provide ESD program guidance or requirements. These include documents such as ANSI ESD S20.20 Standard for the Development of an ESD Control Program, IEC 61340-5-1 – Protection of electronic devices from electrostatic phenomena – General requirements, ANSI/ESD S8.1 Symbols-ESD Awareness, or ANSI/ESD TR20.20 ESD Handbook.

A second group covers requirements for specific products or procedures such as packaging requirements and grounding. Typical standards in this group are ANSI/ESD S6.1 Grounding and ANSI/ESD S541Packaging Materials.

A third group of documents covers the standardized test methods used to evaluate products and materials. Historically, the electronics industry relied heavily on test methods established for other industries or even for other materials (for example, ASTM-257 DC Resistance or Conductance of Insulating Materials). Today, however, specific test method standards focus on ESD in the electronics environment, largely as a result of the ESD Association’s activity. This includes standards such as ANSI/ESDA/JEDEC JS-001Device Testing, Human Body Model.

Standards development and usage is a cooperative effort among all organizations and individuals affected by standards. There are several key ESD standards development organizations.

Military Standards

Traditionally, the U.S. military spearheaded the development of specific standards and specifications concerning ESD control in the U.S. Today, however, U.S. military agencies are relying on commercially developed standards rather than developing standards themselves. For example, the ESD Association completed the assignment from the Department of Defense (DoD) to convert MIL-STD-1686 into a commercial standard called ANSI/ESD S20.20 which was adopted by the DoD July 7, 2000.

ESD Association

The ESD Association has been a focal point for the development of ESD standards in recent years. An ANSI-accredited standards development organization, the ESD Association is charged with the development of ESD standards and test methods. The ESD Association also represents the US on the International Electrotechnical Commission (IEC) Technical Committee 101-Electrostatics.

The ESD Association has multiple standards documents and Technical Reports available. These voluntary standards cover the areas of material requirements, electrostatic sensitivity, and test methodology for evaluating ESD control materials and products. In addition to standards documents, the ESD Association also has published a number of informational advisories. Advisory documents may be changed to other document types in the future.

There are four types of ESD Association standards documents with specific clarity of definition. The four document categories are consistent with other standards development organizations. These four categories are defined below.

Standard: 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: 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 yields a reproducible test result.

Standard Practice: 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 between labs.

Technical Report: A collection of technical data or test results published as an informational reference on a specific material, product, system, or process.

As new documents are approved and issued, they will be designated into one of these four categories. Existing documents have been reviewed and have been reclassified as appropriate. Several Advisory Documents still exist and may be migrated to either Technical Reports or Standard Practices in the future.

The international community, led by the European-based International Electrotechnical Commission (IEC), also develops and publishes standards. IEC Technical Committee 101 has released a series of documents under the heading IEC 61340. The documents contain general information regarding electrostatics, standard test methods, general practices, and an ESD Control Program Development Standard IEC 61340-5-1 that is technically equivalent to ANSI/ESD S20.20. A Facility Certification Program is also available. Global companies can seek to become certified to both ANSI/ESD S20.20 and IEC 61340-5-1 if they so choose. Japan also has released its proposed version of a national electrostatic Standard, which also shares many aspects of the European and U.S. documents.

Perhaps one of the more intriguing changes in ESD standards has been the organizational cooperation developing between various groups. One cooperative effort was between the ESD Association and the U.S. Department of Defense, which resulted in the ESD Association preparing ANSI/ESD S20.20 as a successor to MIL-STD-1686. A second cooperative effort occurred between the ESD Association and JEDEC, which started with an MOU and resulted in the development of 2 documents: a joint Human Body Model document ANSI/ESDA/JEDEC JS-001 and a joint Charged Device Model document ANSI/ESDA/JEDEC JS-002 have been published.

Internationally, European standards development organizations and the ESD Association have developed working relationships that result in an expanded review of proposed documents, greater input, and closer harmonization of standards that impact the international electronics community.

For users of ESD standards, this increased cooperation will have a significant impact. First, we should see standards that are technically improved due to broader input. Second, we should see fewer conflicts between different standards. Finally, we should see less duplication of effort.

For the electronics community, the rapid propagation of ESD standards and continuing change in the standards environment mean greater availability of the technical references that will help improve ESD Control Programs. There will be recommendations to help set up effective programs. There will also be test methods and specifications to help users of ESD control materials evaluate and select ESD control products that are applicable to their specific needs. Additionally, there will be guidelines for suppliers of ESD control products and materials to help them develop products that meet the real needs of their customers.

Standards will continue to fuel change in the international ESD community.

One of these ESD models, Machine Model (MM), is an electrostatic simulation approximating the discharge event produced by machinery, furniture, or automated handling equipment. Present MM test methodology requires the application of three ESD pulses to a pin under test using several stressing configurations (referred to as pin combinations). Further requirements state that a one second delay between consecutive ESD pulses must be used.

This technical report will explore the considerations for handling extremely sensitive devices, particularly with automated equipment.

ESD TR13.0-01: EOS Safe Soldering Iron Requirements

Soldering iron requirements to prevent electrical overstress (EOS) vary throughout the world. EOS issues related to soldering irons have not been researched based on device physics or sound electrical engineering practice. In the United States the most prominent standard has been the MIL STD-2000 series documents that contain soldering specifications. (MIL STD-2000 is now cancelled without replacement as the Military is using civilian documents.) ESD documents often consider the soldering iron requirements part of electrostatic discharge (ESD) protection, but the soldering iron requirements are really intended to control one of the many forms of EOS, not ESD. An underlying, but misguided concern is the possibility of causing a latent defect that would become a latent failure. This issue has been addressed and it has been shown that a latent failure is highly improbable, therefore latency is not an issue, even with a faulty soldering iron.

ESD TR14.0-01: Calculation of Uncertainty Associated With Measurement of Electrostatic Discharge (ESD) Current

Uncertainty is the estimated bounds of the deviation of a measured quantity from its true value. A statement of uncertainty is used to reflect the quality/accuracy of a measured result as compared with the true value which is and usually will remain unknown. The statement of uncertainty is accompanied by a statement of confidence that can be placed in the value of uncertainty. A calculation of uncertainty should be performed for each measured parameter of a calibration. ESD simulator pulses are notoriously difficult to measure because of their fast rise time and shot-to-shot variations in waveform. It is necessary to consider all the possible error sources and calculate the uncertainty when measuring waveforms generated by ESD simulators. Without the statement of uncertainty and confidence, it is not clear if the simulator’s performance truly falls within acceptable limits.

This document will try to give an overview of fundamental electrostatic concepts and electrostatic effects and most importantly of electrostatic metrology, especially what can and what cannot be measured.

ESD TR50.0-02: High-Resistance Ohmmeters - Voltage Measurements

High Resistance Meters are one of the most commonly used meters for the measurement of materials used to control ESD. From work surfaces to floors, evaluators use these meters to qualify materials and audit workstations and ESD safe areas. There are a number of parameters that can cause different readings from these meters when improper instrumentation and techniques are used. These techniques and precautions will be discussed in this technical report in order that the measurement will be as accurate and repeatable as possible for high resistance measurement of materials. Several orders of magnitude differences in measured resistance values have been observed and reported to the ESD Technical Advisory and Services committee. Materials that may have a non-linear resistance for various levels of applied voltages. Also, measurement may vary because of materials used in the electrodes, but these issues are beyond the scope of the investigation conducted for this TR.
