Episode 125: DFM Best Practices with Pride Industries' Engineering Manager Andrew Williams

As all of you are well aware, this show is all about reliability, specifically reliability of circuit assemblies. One challenge that seems to be persistent within our space is design for manufacturability or DFM. If you’re a contract manufacturer, I have no doubt that you’ve had the experience of being asked to build a product that seems unbuildable. One example that rings true in my world was the introduction of bottom terminated components or BTC’s. BTC’s are marvelous components.Because all the lead terminations are below the part, they allow for highly dense component placement and highly miniaturized assemblies. They also presented a number of unique challenges in reflow, in many cases voiding, cleaning, and inspection. Like many other industries, we are not immune to the introduction of new technologies that may lack implementation knowledge. We then spend the next several years at technical conferences and symposiums learning us how to implement these new technologies. There are many acronyms in our industry that begin with DF… Design for testability, mechanical assembly, serviceability, reliability, and so many more. So many in fact, that there is a placeholder acronym for all of the various design fours refer to as DFx. Perhaps the holy grail of DFx is DFM, Design for Manufacturability as it encompasses so many aspects of assembly.To help us understand what exactly is DFM, I invited Andrew Williams to be my guest on this episode. Andrew Williams is the Engineering Manager for Electronics Manufacturing at PRIDE Industries. He has more than 30 years of experience in manufacturing and design and holds an SMT Process Engineer certification from SMTA and an IPC Certified Electronics Program Manager. Andrew is a guest lecturer at UC Davis and Cal State University Sacramento for Supply Chain Management, Operations, and TQM courses, and speaks frequently on DFM, DFS, and other DFX topics and today, he’s my guest on the Reliability Matters Podcast.Andrew's Contact Information: Pride Industrieshttps://www.prideindustries.comandrew.williams@prideindustries.com

Reliability Matters is a podcast on the subject of reliability of circuit assemblies. Reliability "best practices" and success stories are discussed. This podcast features interviews with experts in the electronic assembly industry.All electronic production segments which effect product reliability are on the table. This includes contamination, coating, cleanliness assessment, inspection, building for harsh environments, reflow, printing, failure analysis, board fabrication, and much more.Your Host:Mike Konrad began his career in the electronic assembly equipment industry in 1985. Mike founded Aqueous Technologies in 1992 in response to the Montreal Protocol and the resulting international treaty banning most popular cleaning/defluxing solvents. Mike is an internationally known speaker on the subject of increasing reliability through contamination removal and cleanliness quantification techniques and procedures. Mike was awarded “Distinguish Speaker Status” with SMTA in 2018 and received the “Rich Freiberger Best of Conference Award” in 2019.Mike is a member of the SMTA Global Board of Directors where he is Vice President of Communications. Mike is also Vice President of Technical Programs for the Los Angeles / Orange County SMTA Chapter.Visit the Reliability Matters Podcast Website:https://www.reliabilitymatterspodcast.com
