3M launched its comprehensive 3M Static Management Program, designed to improve product quality and production yields for customers requiring high reliability in the electronics manufacturing industry. This unique program offers a full complement of product, software and service solutions, powered by the technical expertise of 3M staff and the company’s proprietary technologies.

The electronics industry is continually shifting. Device density and technology is more complex. Electronics manufacturing is more heavily reliant on out‑sourcing. The ESD industry seems to have jumped into this swirling eddy headfirst. ESD control programs have mushroomed. Black has been replaced by green, blue and gold. Shielding bags dominate the warehouse. Ionizers exist along side wrist straps and ground cords. An early history of “smoke and mirrors,” magic and lofty claims of performance is rapidly and safely being relegated to the past.

Anyone who has worked in Quality or Reliability in a large corporation knows that developing and presenting credible failure cost information can be difficult. This is particularly true for ESD, where the events are invisible and not nearly as well understood as other more obvious classes of failure, such as mechanical or contamination. The “real” cost of ESD can be a hot topic of discussion each year when program budgets are being developed for manufacturing and R&D programs. The challenge is that every year there are new high-level people in the financial and planning organizations who are not technical experts and who are asking hard questions about the justification for the ESD investment. In years when revenue is down, the questions become more difficult and better evidence is often demanded. The author was directly involved in this process for 15 years, starting in 1986. At the time the following quote was a part of many ESD funding discussions; “… in the electronics industry, losses associated with ESD are estimated at between a half billion and five billion dollars annually.” The exact original reference for this assertion has been lost, at least to this author. Nonetheless it was used many times over the next few years in presentations to the corporate check writers. Furthermore, during research for background information for this article, the exact same quote appeared (unattributed) in an article from 1992 [1] and in a book published in 2006 [2]. Needless to say, a well-stated assertion of value can go a long way – at least in trade literature. However, this author can also report that the usefulness of this, inside the corporation, eroded much faster. By 1990, a well-known director in Bell Labs said; “… that was then… I think this problem has been solved!” Many of us would scoff at such a declaration, knowing full well that ESD problems were continuing to occur. However, the directors’ challenge was an appropriate one. His experience came from the semiconductor process world where he had seen significant ESD sources eliminated and device thresholds (albeit HBM only) steadily increase. Corporations would like their investments to be justified by more timely and relevant data and observations.  They ask, “What is the “real” cost?”
