Reliability Matters

Episode 35: A conversation with Dr. Darren Williams of Sam Houston State University about cleaning processes and materials.

Dr. Williams has been at SHSU since 2004 teaching Physical Chemistry, Forensic Chemistry, and graduate courses in Spectroscopy and Thermodynamics. He came to Huntsville from the US-DOE Pantex Plant in Amarillo. He taught at West Texas A&M University for four years after obtaining his Ph.D. from Oregon State University in 1997. He is originally from Fort Worth, and obtained his B.S. in chemistry from the University of Texas at Austin in 1992.

He is the author of over two dozen research articles and book chapters covering a broad range of topics, such as cleaning process changes to reduce environmental impacts, contact angle methods for cleanliness verification, prediction of the spectroscopy of aged explosives, and chemical education improvements in Physical Chemistry.

Dr. Williams leads the Cleaning Research Group at Sam Houston State University that studies all aspects of finishing and cleaning of high-value and mission-critical parts in the aerospace, medical, electronics, and manufacturing sectors. His lab has dry vapor spray, ultrasonic, vapor degreasing, and vacuum cycle cavitation cleaning equipment. The CRG formulates and tests azeotropic solvent blends, and measures flashpoint, viscosity, surface tension, and specific gravity. Much of the research is performed and published openly, but the CRG also performs contracted work under non-disclosure for external clients.

Dr. Williams created the Product Quality Cleaning Workshop in 2018 to address the growing need for education on cleaning processes in industry. The next workshop is May 13-14th, 2020 at Sam Houston State University in Huntsville, TX. Registration is now open at https://tinyurl.com/wcnjjw5

Episode 34: A Conversation with "The Cleaning Lady and the Rocket Scientist" Barbara and Ed Kanegsberg about all things cleaning. Barbara and Ed are the authors of Handbook for Critical Cleaning available here:

Episode 33: Altium's Judy Warner (a fellow podcaster) interviews Reliability Matter's host Mike Konrad on the subject of Cleaning for Reliability. Judy is the host of Altium's On-Track podcast . More podcasts from Judy are available here: https://resources.altium.com/altium-podcast

Episode 32: A Conversation with Greg Smith and Tony Lentz About Stencil Design and Void Reduction

Greg and Tony talk to me about stencil design and how to reduce voiding. Voiding is a key concern in specific electronic applications including automotive and LED electronic manufacturing. Greg and Tony published a paper entitled "Root Cause Stencil Design for SMT Component Thermal Lands"

Episode 31: A Conversation with Scoop's Phil Stoten recorded at SMTAI in Chicago. Phil discusses Industry 4.0 and other industry-related topics.

Episode 30: A Conversation About Reflow Technology with Heller Industries' CEO David Heller. David joined the family business in 1987, twenty seventy years after its founding. David shares what reflow ovens were like at the beginning stages of surface mount technology and the numerous technological changes required along the way.

Episode 29: Recorded at SMTAI in Chicago - A Return Conversation with Foresite's Lead Investigator Eric Camden. Eric discusses his experiences in field failure analysis including the failures and causes.

Episode 26: My guest today is Alun Morgan, he is a Technology Ambassador at Ventec International Group.

Our conversation today is all about cars, and the increased reliability expectations associated with their electrical systems. The electronics in modern vehicles provide an unpresented level of safety, not just for the driver, but for those people and objects around the vehicle. Because our cars go in and out of harsh environments, the circuit assemblies within the car are subjected to heat, humidity (and other sources of moisture), which contribute to reliability and therefore safety.

We’ll discuss one of the primary failure mechanisms of circuit assemblies, an issue that can affect the operation of the safety systems within the automobile, it’s a real issue that for many is not well known.

I spoke with Alun from his office in Scotland.
