Ted Dangelmayer has held leadership positions such as Chairman of the Lucent Global ESD Leadership Team, President of the International ESD Association, Chairman of the ANSI/ESDA Standards Committee, and General Chairman of the EOS/ESD Symposium. Under Ted’s leadership, Lucent Technologies ­ North Andover, MA, was the first site in the USA to become S20.20 certified. At the time, the Lucent site had 2,000,000 square feet of floor space and 12,000 employees. The lead DNV auditor was quoted as saying "I've audited literally hundreds of ESD programs and, without a doubt, the Lucent program is the best I have ever seen. It’s a world class benchmark, and you can quote me on that!"

He has published numerous magazine articles, technical papers and two books, ESD PROGRAM MANAGEMENT.

Ted holds three patents, is NARTE Certified, and has successfully completed the ESD Association ANSI/ESDA S20.20 Course for Program Managers and Consultants. He is currently President of the Northeast Chapter of the ESD Association and a member of the ESD Association International Council of Education and 2003 Technical Program Committee.

Dr. Terry L. Welsher retired from Lucent Technologies-Bell Laboratories Engineering Research Center in 2001 as the Director of the Quality, Test & Reliability department. He began his career in Bell Labs in 1978 where he worked on electrical conduction mechanisms in insulating polymers and electrolytic corrosion failure mechanisms in electrical interconnection materials. In 1984 he was appointed Distinguished Member of Technical Staff for his work in these fields. In 1986 he was promoted to Technical Manager to re-constitute the Bell Laboratories core expertise in electrostatic discharge (ESD). The newly formed group proceeded to produce a string of ground-breaking contributions to the field and played a key role in advancing industry standards. In 1994, he broadened his group's activities to all aspects of hardware reliability for Lucent Technologies with special emphasis in environmental stress testing (EST) and product reliability prediction and planning. In 1998 he was promoted to Director of the Quality, Test & Reliability Center of Excellence where he directed the development and deployment of product quality, test and reliability assurance practices for Lucent Technologies business units. This work included design for testability of integrated circuits, board and system level test and diagnosis and special techniques for testing of RF and optoelectronic systems and components. Dr. Welsher was


Senior Vice President



Chairman of the ESD Association Standards Committee 1988-1989. He was Technical Program Chair in 1991, Vice General Chair in 1992 and General Chair in 1993 of the EOS/ESD Symposium. He served as member of the Symposium Board of Directors 1993-1995. He has also been active in quality standards and roadmapping activities with Sematech, the ESD Association and the JEDEC 14 Quality and Reliability Committee. He has also served on the Board of Directors of JEDEC. He holds a B.S. in Chemistry from Florida State University and Ph.D. in chemical physics from the University of Texas at Austin. He is author or co-author of thirty-five papers in solid state physics, applied mathematics, organic chemistry, electronics reliability and electrostatic discharge.



Dr. Louis F. DeChiaro received the B.S., M.S., and Ph.D. Degrees in Physics from The Stevens Institute of Technology in 1970, 1972, and 1979, respectively. Between 1972 and 1976, he served as an Electronic Systems Officer with the USAF (SAC) command. Dr. DeChiaro spent five years at AT&T Bell Laboratories in Allentown, PA, specializing in the design and reliability of silicon ICs and device-level ESD effects. Upon leaving Bell Labs in 1985 to join the staff at Telcordia Technologies (then known as Bellcore) in Red Bank, NJ, Dr. DeChiaro specialized in semiconductor laser reliability and system-level ESD effects. From 1995 through the Fall, 2002, he was with Lucent Technologies / Bell Laboratories in Princeton and Holmdel, NJ, specializing in device and system-level ESD effects. Dr. DeChiaro retired from Bell Labs as a Distinguished Member of the Technical Staff (DMTS) in 2002 and has since been pursuing an academic career at The Richard Stockton College of NJ, where he serves as an Associate Professor of Computational Science. Dr. DeChiaro is a member of Tau Beta Pi.

Ginger Hansel joined Motorola's Semiconductor Products Sector in 1981 as a Test Process/Equipment Engineer to analyze and improve manufacturing operations. She founded and led the manufacturing ESD control team that trained, audited, qualified materials, and established innovative solutions throughout the semiconductor sector. Under her leadership, the team reduced a 40% failure rate in one test operation to almost zero through the targeted introduction of specific ESD control materials and ESD Awareness training. Ginger brought ESD awareness to her other roles as Engineering Section Leader, Technical Training Manager, QA Engineer, Business Metrics Engineer, Data and Document Control Manager, Program Manager and Technical Product Marketing Manager. Ginger retired from Motorola/Freescale in 2004.

She has published numerous magazine articles and technical papers on effective ESD control programs and awareness training; examples include "The Production Operator: Weak Link or Warrior in the ESD Battle" and "Cost Effective Failure Analysis Method for Detecting Failure Site Associated with Extremely Small Leakage". She has taught seminars and workshops around the country and abroad. For over 20 years, Ginger has held leadership positions in the International ESD Association such as President, Board of Directors, Chairman of the Association Council on Education and has served on the Steering, Technical Program, Standards, and other committees.
