Learn how to prepare for the “Perfect ESD Storm” that is brewing in the electronics industry. The trend towards extensive use of ultra-sensitive components (Class 0) and the widespread lack of charged device model (CDM) understanding are brewing the “Perfect ESD Storm.” It is no longer business as usual, and it can take up to two years to prepare. This tutorial is intended for professionals who have a basic understanding of ESD but are not fully aware of CDM control techniques or the industry trend toward extremely sensitive devices and the counter measures that are necessary. Learn the answers to your questions as well as these examples: Are you skeptical about this news of a Class 0 trend? Is it really happening? Is it likely to be a problem in your factory? How big a problem is CDM in manufacturing? What is different about CDM controls? How do I tailor ANSI/ESD S20.20 for CDM and Class 0? Join us for this highly interactive tutorial and learn why this is inevitable and how to prepare for it.

The complexity of properly installing workstations is often underestimated. On the ‘surface’ it appears to be a simple installation of an ESD static dissipative mat or ESD hard laminate. However, there are important issues learned from years of experience that impact cost, durability, ESD performance, maintenance, and compliance verification. A good ESD control workstation is the cornerstone of ESD program management (EPM). Workstations used in processing ESD susceptible items are intended to maintain a near zero potential by providing ground paths for basic components of the workstation and a connection point for personnel grounding apparatus. The workstation should provide protection from charged device model (CDM) ESD as well as human body model (HBM). This practical tutorial will teach you how to set-up an effective ESD controlled workstation that accomplishes these goals. It will cover selection and qualification of the required materials and how to install them correctly. Other workstation issues will be discussed including: application of ionization, garment grounding, ESD chairs, handling containers, tools, and compliance verification consistent with ESD TR53.

September 10 39th Annual EOS/ESD Symposium DD/FC130: System Level ESD/EMI: Testing to IEC & Other Standards

This tutorial is intended to help those tasked with testing products to system level ESD standards by providing first an overview of how real-world system ESD events are simulated in different standards and testers in general, and then provide detailed information on IEC 61000-4-2, the most widely used standard. This introduction will highlight the similarities and differences between IEC, ANSI, Telcordia, and some automotive ESD standards. We will answer common questions regarding test setups, test points, and procedures, and address key issues, including: 1) differences between “verification” and “calibration” and when is each required; 2) test equipment requirements, the test environment, ground connections, return paths, and ground plane effects. 3) Testing procedures with demonstration on actual products, how the tester and procedure affects test results, and problems with test result variations due to simulator influences; 4) definitions of testing failure criteria for the product; 4) what points need to be tested and why, guidance on determining “operator accessible” points and ports, exempted points and ports, and what to do around connectors and connector pins. 5) ANSI and other ESD standards, the drive toward harmonization with IEC, the scope of different standards, and why they are unlikely to converge. This system level ESD tutorial will cover different perspectives on ESD as applied to electronic systems from the user’s, the designer’s, and even the designer’s competitor’s points of view.

September 10 39th Annual EOS/ESD Symposium, FC164: Costly Controversial ESD Myths

Location: Westin La Paloma Tucson, AZ, USA

There are a number of common misunderstandings and controversies about electrostatic discharge (ESD) program management that can have significant impact on the implementation and maintenance of the ESD program. These misunderstandings or “myths” result in unnecessary expenditures and/or result in a compromise of the program integrity. These myths and controversies, such as latency, are often cited by skeptics not wanting to adhere to certain standard ESD procedures. As a consequence, it is important to identify and dispel the myths as well as to understand the potential impact of latent failures.

This tutorial highlights 10 common myths and supporting success studies as well as a success study in latency. The myths and success studies presented here were chosen to provide real-world examples of how an ESD program can be strengthened by understanding the fallacy in each of the myths. This understanding will result in more reliable products that are also more cost competitive. Although not a myth, latency is a significant reliability consideration that is surrounded with controversy. Some experts will argue that latency is virtually non-existent and others will claim that it is the dominant failure mode. Reality lies somewhere in between. The latency study cites irrefutable evidence of latent failures in alarming proportions that must be factored into ESD programs and product design.

Advanced ESD controls and auditing measurements for CDM & Class 0 (ultra-sensitive) devices and circuit boards are not well known and there are many technical and strategic pitfalls that must be avoided. Industry definitions (threshold levels) for Class 0 will be described and the history of their use will be reviewed. The Class 0 category is broken down into sub-categories of increasing risk. Students will learn how to make valid measurements, avoid common pitfalls, and how to use this data to successfully handle Class 0 sensitivities. Advanced measurements will be described including event detection and high speed current measurements. Students will learn when each measurement type is useful. Compelling case studies will illustrate these techniques and the success they produce.

ESD Control procedures for Class 0 manufacturing require customization, attention to detail and a full understanding of the technology. Thus, each company will need to develop a Class 0 ESD subject matter expert (SME) to ensure the correct and cost effective counter measures are taken. SOPs (special operating procedures) developed by SMEs will be discussed that have proven to virtually eliminate Class 0 failures.

This tutorial will be highly interactive with live demonstrations, in-plant photographs, and video clips. Students will be encouraged to ask questions and actively participate in the discussions. References to technical literature on ultra-sensitive devices will be included.

Electrical overstress (EOS) is a major cause of device failure in manufacturing and in the field. Despite this, there is relatively little information on the sources of EOS and on prevention practices, particularly for the factory. In this tutorial, the fundamentals of device overstress are reviewed. Relationships among device EOS stressing models, such as the Wunsch-Bell curve, are discussed. The causes of EOS and EOS-like events in manufacturing are described and categorized by source and by stress-type. The difficulties in distinguishing between power-induced EOS and high current ESD events such as charged-board events (CBE) and cable discharge events (CDE) are discussed. Case histories, including failure analysis and root cause determination, are presented and the few relevant industry specifications are reviewed.

Accurate data is the foundation of effective ESD program management. This hands-on tutorial will explain and demonstrate the proper use of ESD test equipment such as static locators, resistance meters, charge plate monitors, and event detectors. We will examine pitfalls of using these common instruments that can result in an incorrect representation of the ESD risk. For example, static locators can give misleading readings if the effects of voltage suppression are not taken into account. We will also discuss the effective use of ionization since ionizers that are not measured, maintained, and located correctly may contribute ESD hazards to the work area. Each student will participate in class exercises to perform these tests. The hands-on experience is the best way to understand the seriousness of the pitfalls and the benefits to taking the proper precautions. What you learn will help you avoid frequent auditing problems and improve your compliance verification program.

    • This program reviews the evaluation and periodic verification (audit) measurement procedures for the technical requirements specified in the ANSI/ESD S20.20 ESD program development standard. Detailed explanation of instruments, fixtures, and accessories function and usage are provided. Then, the details of “How to” measure are explained and demonstrated. Measurements include those listed in Table 1: Grounding/Equipotential Bonding Requirements; Table 2: Personnel Grounding Requirements; and Table 3: EPA/ESD Control Items. These recommended measurement procedures confirm the proper operation and use of ESD control products and materials selected as part of a facility’s S20.20 ESD control program.
  • [MAY 21, 2015, 8:30 a.m. - 12:00 p.m.] ESD Models and Test Methods
    • The familiar Human-Body Model (HBM) and Charged-Device Model (CDM) are commonly used simplifications of ESD events which have been employed in the electronics industry to characterize the vulnerability of devices to ESD events in production. Standard test methods have been adopted by the electronics industry based on these models. In many cases, HBM withstand thresholds are available on device data sheets. However, IC suppliers generally fail to put CDM withstand voltages on datasheets. These data can be used to set requirements on suppliers, classify components and manage levels of ESD control in production. However, the limits and applicability of these models are not widely understood. Some aspects of the models are arbitrary and in a given failure scenario may not be the best representation of a damaging event. Also other models (or events) are also gaining use and acceptance in the industry such as the Charged-Board Event (CBE) and Cable Discharge Event (CDE). Other models such as the so-called Machine Model (MM) are being phased out. Finally, system designers have been attempting to apply system ESD models such as IEC 61000-4-2 at the device level in ways that do not produce useful results and can be counter-productive. In this webinar, we review the basis for all these models and relationships among them. We will discuss the use of device classifications in designing production control programs and when and how to use (and not use) the various models.

Class 0 Devices & Boards - ESD Controls and Auditing Measurements

Time: 8:30 a.m. - 4:30 p.m.

Location: Teradyne Conference Center 600 Riverpark Drive • North Reading, MA

Speakers: Ted Dangelmayer & Terry Welsher, Dangelmayer Associates LLC

Tutorial Co-Sponsors: ESDA and ESDA Northeast Chapter

Information and registration: ESDA Northeast Chapter or download the RTP Flyer: PDF Flyer

Advanced ESD Controls and Auditing Measurements for CDM & Class 0 (ultra–sensitive) devices and Circuit Boards are not well known and there are many technical and strategic pitfalls that must be avoided. Industry definitions (threshold levels) for Class 0 will be described and the history of their use will be reviewed. The Class 0 category is broken down into sub–categories of increasing risk. Students will learn how to make valid measurements, avoid common pitfalls and how to use this data to successfully handle Class 0 sensitivities. Advanced measurements will be described including event detection and high speed current measurements. Students will learn when each measurement type is useful. Compelling case studies will illustrate these techniques and the success they produce.

ESD Control procedures for Class 0 manufacturing require customization, attention to detail and a full understanding of the technology. Thus, each company will need to develop a Class 0 ESD subject matter expert (SME) to ensure the correct and cost effective counter measures are taken. SOPs (Special Operating Procedures) developed by SME’s will be discussed that have proven to virtually eliminate Class 0 failures.

Class Exercises will allow each student to make advanced measurements necessary for Class 0. They will also experience common measurement the pitfalls and how to avoid them.

This tutorial will be highly interactive with live demonstrations, in-plant photographs, and video clips. Students will be encouraged to ask questions and actively participate in the discussions. References to technical literature on ultrasensitive devices will be included.

Next Generation ESD Scanning Techniques for Protection Circuit Analysis and Debug - General Meeting NE Chapter ESDA

Time:5:30 PM

Location: MIT, Lexington

Speaker: Jeff Dunnihoo, Dangelmayer Associates & Pragma Design

Sponsors: Meeting of ESDA Northeast Chapter & IEEE Reliability

While there are numerous solutions for characterizing and qualifying ESD transient robustness levels and hard–failures, there are extremely limited options for soft-failure, or “ESD upset” root-cause identification and analysis.

Pulse simulator systems have been developed by the industry with reasonable repeatability for product characterization and qualification. However, these techniques were never intended for use by the system design engineer as root–cause analysis and debug tools.

We will discuss in detail a new solution to this problem that has adapted EMI/EMC 3D scanning systems in conjunction with injected pulse generator simulators in both “current reconstruction” and transient susceptibility scanning modes. These systems attempt to identify which individual components and nodes actually “feel” the residual and induced transient pulses, how much, and to what effect.

We will also present some reconstructed animations of measured ESD charge distribution during a strike on an actual system board, along with some case studies and take a look toward the future of ESD scanning/reconstruction technology, including Embedded ESD Scanning as described in this recent EDN article.

ESD Class 0 – Who’s at Risk and How to Avoid High Failure Rates

Time:5:30 p.m.

Location: MIT Lincoln Laboratory, 244 Wood Street, Lexington, MA 02420

Speaker: Ted Dangelmayer, Dangelmayer Associates L.L.C.

Sponsors: Joint Meeting of ESDA Northeast Chapter and IEEE Reliability Chapter

While most companies are acutely aware of the hazards of ESD (electrostatic discharge), few are aware of how to handle the extreme sensitivities of ESD Class 0 devices or if they are at risk of quality or reliability failures. Others are unaware of device trends towards these ultra-sensitive components and the resulting reductions in IC device design target levels.

Join us for this highly interactive presentation and learn if you are at risk and also about the complexity, customization and attention to detail required to successfully produce products utilizing Class 0 devices. You will also learn how to classify Circuit Board Assemblies that contain Class 0 components. ESD Class 0 Case Studies will be presented such as when 100% failure rates brought production to a standstill during ramp up of a one Billion dollar product line. Another Case Study documents 22% failures rates with a good S20.20 program in place.

If you are waiting for a Class 0 industry standard, it is unlikely that any standards body will be able to develop a "Class 0 Standard Process" in the foreseeable future. The variables and complexity are far too great.

Location: Teradyne Conference, North Reading, MA

Speaker: Terry Welsher, Dangelmayer Associates L.L.C.

Sponsors: Northeast Regional Tutorial Program. Cosponsored by the Northeast Chapter ESD Association

Electrical overstress (EOS) is a major cause of device failure in manufacturing and in the field. Despite this, there is relatively little information on the sources of EOS and on prevention practices, particularly for the factory. In this tutorial, the fundamentals of device overstress are reviewed. Relationships among device EOS stressing models, such as the Wunsch-Bell curve, are discussed. The causes of EOS and EOS-like events in manufacturing are described and categorized by source and by stresstype. The difficulties in distinguishing between power-induced EOS and high current ESD events such as charged-board events (CBE) and cable discharge events (CDE) are discussed. Case histories, including failure analysis and root cause determination, are presented and the few relevant industry specifications are reviewed.

Abstract: Joint IEEE & ESDA Northeast Chapter

Electrical Overstress (EOS), the Sources and Solutions by Dr. Terry Welsher

The class of device failures typically called Electrical Overstress (EOS) has been getting increased attention in the last two years. Historically, the effects of ESD on integrated circuits, particularly handling in the factory, have received much attention in technical literature, standards bodies and educational workshops and tutorials. This has been a largely successful endeavor by the industry. As a result, in many companies EOS has become the next layer of the onion to pursue. Common device design practices have not been developed to nearly the same extent; system level approaches tend to be ad hoc, and responsibility for controlling potential sources in manufacturing tends to be diffused or non-existent.

In this presentation will be description and discussion of the differences and similarities between ESD and EOS caused by other sources (excessive voltage, current or power). The current state of EOS prevention will be reviewed and examples and case histories given. Also covered will be ESD events that can be misdiagnosed as power-induced EOS (Charged-Board and Cable Discharge Events). Recent work in standards organizations and other industry groups will be reviewed and some mitigation techniques are presented.

Instructor: Ted Dangelmayer, Dangelmayer Associates

More Info: Nov15_2012CommonESDMyths.pdf

Course Description
Join us for this interactive webinar presented by Ted Dangelmayer to learn more about the most Common ESD Myths, the misplaced confidence, and unnecessary costs they create.

There are a number of common misunderstandings that can have significant impact on costs, quality and reliability of the ESD program. Some of these misunderstandings or "myths" result in costly unnecessary expenditures; others result in a compromise of the program integrity. These same myths are often cited by skeptics not wanting to adhere to standard ESD procedures. As a consequence, it is important to identify and dispel these myths.

Join us for this highly interactive discussion and learn about common myths such as:

Myth: Circuit Boards are Less Sensitive to ESD than Devices
Myth: HBM Data Are Sufficient for Determining Device Sensitivity Levels
Myth: MM Is A Valid Simulation Related To Machines
Myth: Air Flow Causes Charging
Myth: Metalized or Highly Conductive Shielding Layers Are Essential
Myth: Humidity Control is Essential for ESD

Ultra-Sensitivity Trends and CDM

Time: 11:00 a.m. Eastern Time

Location: Online Training – Webinar

Instructor: Ted Dangelmayer, Dangelmayer Associates

More Info: http://esda.org/onlinecourses.html

Course Description
Learn how to prepare for the inevitable trend toward ultra-sensitive components (Class 0) that is sweeping the electronics industry and the wide spread lack of understanding about CDM (Charged Device Model) that is making it more difficult. Case studies will illustrate how CDM failures can persist even with a robust HBM program in place. A series of photographs of common CDM issues in manufacturing will enable students to visualize how to implement CDM controls. A brief summary of the work by the Industry Council on ESD Target Levels will be included. It is no longer business as usual and it can take up to two years to prepare (example - equipment retooling etc.). Are you skeptical about this news of a Class 0 trend? Is it really happening this time? Is it likely to be a problem in your factory? How big a problem is CDM in manufacturing? What is different about CDM controls? Join us for this highly interactive tutorial and get the answers to your questions.

Webinar – How to Know if Your ESD Program is Doing Anything

Time: 2 PM Eastern Time

Location: Online Training – Webinar

Instructor: Arnie Steinman, Dangelmayer Associates

More Info: Methods for Determining the Impact (PDF)

Course Description
Many ESD Association standards test a property of a static control method, rather than showing the effect of using the method on production problems. This webinar discusses how to determine if using a static control method has any impact on static problems. It starts by examining static problems, ESD damage to ICs, contamination affecting semiconductor yields, and ESD-related EMI affecting equipment performance. Common test methods and equipment used to identify these problems will be discussed to show their applicability in determining the impact of a static control method on the problem.

Focusing on production equipment, this webinar will consider examples of test methods applied to the final test of ICs, particle testing for contamination of semiconductor wafers, and equipment uptime studies. The webinar will note the importance of statistical analysis of the test results, giving an example of how it was applied in a contamination control study of semiconductor production equipment. The goal of the webinar is to demonstrate that normal production test methods are a consistent source of information about the effects of a static control program.

IEW 2012 Discsussion Group Topic - ESD thresholds and actual risk of failure

Time: TBA

Location: Priory Corsendonk, Oud Turnhout, Belgium

Moderator: Terry Welsher, Dangelmayer Associates

More Info: http://www.esda.org/iew.htm

How can we change the current way of working to include statistics of ESD events and product failure? HBM and CDM ESD thresholds have been useful as “figures of merit” to drive improvements in protection circuits. However, the relationship of these thresholds to actual quality or reliability risks is not well-understood. Many users believe that the risk of failure rises dramatically when the threshold falls even a small amount below the usual threshold requirements. This discussion group will explore better ways of communicating the risk of failure to users, better measures of ESD robustness than the simple threshold value and whether it is possible to characterize an ESD manufacturing process based on measurements (auditing).

Class 0 Advanced ESD Measurements on Automated Equipment

Time: 2:00 to 3:30 pm Eastern

Location: Internet - Webinar

Moderators: by Donn Bellmore, Advanced ESD Services +, and by Terry Welsher and Ted Dangelmayer, Dangelmayer Associates

More Info: http://www.dangelmayer.com/Class_0_Advanced_ESD_Measurements_on_Automated_Equipment.html

Join us for this interactive joint webinar and learn how to effectively deal with measuring ESD in automated equipment.

The ESD analysis of automation equipment is complex, not well understood and often not done correctly. The escalating use of Class 0 (ultra-sensitive) devices and high failure rates has made this analysis critically important. During this webinar you will learn about today's advanced test equipment, how to more readily identify sources of ESD damage and how to rectify or prevent ESD damage including Class 0.

This webinar will be highly interactive with in-plant photographs and compelling Class 0 case studies. The photographs illustrate the details of appropriate measurements and how to avoid the numerous pitfalls. Students will be encouraged to ask questions and able to participate verbally in the discussions.

You will learn how to make valid measurements, avoid common pitfalls and how to use this data to successfully handle Class 0 sensitivities in highly automated equipment.

The Webinar format offers VoIP and phone line connections. You will be able to talk directly with our team of experts and see our cursor pointing to discussion topics and photos in the slides.
