ASME Santa Clara Valley Presents:
A talk by Dr. Audrey Fasching and Dr. Daniel Donahoe of Exponent
The Restriction of Hazardous Substances (RoHS) Directive
Thursday, April 20th, 2006
The European Directive titled Restriction of the Use of Hazardous Substances (RoHS) goes into effect on July 1st. This Directive bans cadmium, lead, mercury, hexavalent chromium and two fire retardants. This topic is of special interest to ASME members, because, as is often the case in electronics technology, issues straddle traditional disciples. As part of compliance with RoHS, many electronic companies are in the process of switching from the traditional lead-tin solder to the newer lead-free solders. During this transition, many difficulties relating to the manufacture and service life of these parts are in question. This talk will include a discussion of possible lead-free replacement alloys and the effect on manufacturing; as well as, processing a mixed (lead and lead-free) part, and the expected reliability.
Location: Exponent, 149 Commonwealth Drive, Menlo Park, CA 94025
6:30pm registration, light dinner, 7pm talk
Cost: No charge – Exponent is sponsoring a light dinner. (Please RSVP so we will have enough food) Questions? Contact firstname.lastname@example.org or 408-360-0669
Speaker: Audrey Fasching, Ph.D., P.E.
Dr. Audrey Fasching is a Senior Engineer in Exponent Failure Analysis Associates’ Mechanics and Materials practice. Dr. Fasching specializes in welding, brazing and soldering metal alloys, materials science, and failure analysis. Dr. Fasching has specific experience within medical device, consumer electronics, automotive, and aerospace industries specifically for aluminum and other non-ferrous alloys. Dr. Fasching’s research includes, welding, brazing and soldering, microstructural morphology/evolution, heat treatment, and materials selection. Dr. Fasching is an Adjunct Professor in the Mechanical Engineering Department at Santa Clara University, where she teaches undergraduate-level materials science, and graduate-level materials science and welding and joining of engineering materials. Prior to joining Exponent, Dr. Fasching was employed as a Senior Research Engineer, at Kaiser Aluminum’s Center for Technology.
Speaker: Daniel N. Donahoe, Ph.D., P.E.
Dr. Daniel N. Donahoe is a Managing Engineer in Exponent’s Mechanical Engineering and Materials/Metallurgy practice. Dr. Donahoe has over twenty-five years of experience. Prior to joining Exponent, he has been employed at Lockheed, Motorola, Ford Aerospace, Teledyne, Compaq Computer and Iomega, and the University of Maryland’s industry and government sponsored CALCE, Electronic Products, and Systems Center. His functional assignments include work as a design engineer, reliability engineer, thermal engineer, manager, technologist, and scientist. In military electronics he worked on electronics exposed to extreme environments ranging from the high acceleration loads of gun launch to thermal challenges faced in life support, and the design of radar systems. In addition to electronic products exposed to exotic environments, he has worked on cost-driven commercial electronics products such as cooling of computer components. He has worked on integrating rack and stacked electronics into facilities, especially focusing on the design of Heating, Ventilation and Air Conditioning (HVAC)). His electronic packaging analysis skills include thermal analysis, stress and dynamics analysis, and failure analysis. His Ph.D. dissertation on ceramic capacitors included failure analysis work using modern tools of failure analysis including the environmental scanning electron microscope (ESEM™), electron backscatter diffraction (EBSD), and focused ion beam (FIB). Dr. Donahoe worked on several industry standards related to electronics. He has served as an Associate Editor of the IEEE Transactions on Components and Packaging Technologies for seven years. Upon return to California, he is beginning service on the Silicon Valley Administrative Committee for the IEEE Components and Packaging Technologies Society. He has served as a teaching assistant for an intermediate heat transfer course (University of Illinois), an instructor for high school physics (Judge Memorial Catholic High School), for junior college courses in basic electronics and in statistics (Maricopa County Junior Colleges), and for a graduate course on sensors (University of Maryland).
