RM 130: Human-Centered Approaches to Innovation with Dr. Alexis Abramson

Baby Boomers are entering retirement in greater numbers. From now until 2030, 10,000 Boomers each day will hit retirement age. Millions will begin to officially retire. This is creating a terrific opportunity for young college graduates to enter our industry.

Several years ago, I was a speaker at the SMTA, Pan Pacific Strategic Electronics Symposium in Hawaii. I shared my breakfast table with a longtime colleague, Dr. Ron Lasky, a professor at Dartmouth College. Over the course of breakfast, he asked me how I got into this industry and, more specifically, how I started my company. Dr. Lasky is an engineering professor at Dartmouth’s Thayer School of Engineering. He also teaches entrepreneurship to his soon to be engineers. Dr. Lasky invited me to come speak to his students. I was more than happy to take him up on his offer, and I have spoken to his students on the subject of entrepreneurship every year for the past several years.

I have been impressed by the emphasis on entrepreneurship within the Thayer School of Engineering. We live in a time of marvelous evolution within the electronics space. So many new and innovative electronic products are being introduced, fueled by IoT (Internet of Things), the electrification of automobiles, advances in communication, and so much more.

Education is the bedrock of our industry. It is the foundation for which much of our industry and the products we make are built upon. I’ve had Dr. Lasky on my show several times, and I thought it would be a great idea to invite his boss, the dean of Dartmouth’s Thayer School of Engineering, onto the program.

Dr. Alexis Abramson is the 13th dean of the Thayer School. Prior to joining Dartmouth, she was the Milton and Tamar Maltz Professor of Energy Innovation at Case Western Reserve University and served as a director of the university’s Great Lakes Energy Institute focused on creating sustainable energy technology solutions. During the Obama administration, Dr. Abramson served as chief scientist and manager of the Emerging Technologies Division at the US Department of Energy’s Building Technologies Program. In 2018, she served as technical adviser for Breakthrough Energy Ventures, a $1 billion effort launched by Bill Gates to combat human-driven climate change.

Dr. Abramson’s research has focused on novel techniques for thermal characterization of nanostructures, the design and synthesis of unique nanomaterials for use in alternative energy applications, virtual energy audits for building energy efficiency, and strategies to accelerate technology commercialization at universities and research institutions.

Dr. Abramson earned a bachelor's and master's in mechanical engineering from Tufts University and a Ph.D. in mechanical engineering at the University of California, Berkeley.

RM 129: Network Reliability - Avoiding Cyber-Security Threats

The Reliability Matters podcast is almost exclusively about reliability. Specifically, reliability of circuit assemblies. We discuss production best practices, design for manufacturing and reliability. Failure analysis, and more. We’ve reviewed the latest trends in industry 4.0, the connectivity of machine to machine and machine to management. We discussed big data and how to make all of our newly acquired data relevant and actionable. For all this to occur, our computers must function properly. They must perform the assigned tasks and communicate large sums of data.

What happens to our production line if the computers stop functioning? What would happen if our network ceases to operate? We’ve all witnessed the airline industry grind to a halt recently due to computer failures and connectivity issues. The fact is, very few industries can function properly or even at all if the computer systems fail. I’m not referring to quality issues within the computer or network’s internal circuit assemblies. I’m referring to malware, ransomware, and other nefarious actions brought on hackers with the intent to disrupt companies, industries, and governments, frequently with the goal of returning (or promising to return) your own data in exchange for an exorbitant payment.

Our industry, like many others is completely dependent on computers and connectivity. Without ether, most production lines will simply sit idle. How can we avoid this terrifying scenario? How do hackers gain access to our computers and networks? How can we add reliability to our computer and network policies and procedures?

To answer these and other related questions, we talked with network security expert Adrian Francoz, cofounder and CEO of Zeta Sky, a managed IT support and cybersecurity services company lives in the world of cyber security. He and his company protect their customer’s networks through the implementation of security best practices and constant training, both for his customers, and for his own staff. After all, hackers and other bad actors are hard at work searching for the next scam, vulnerability, and the opportunity to score a huge payday, all at our expense.

RM 127: Phil Zarrow and Jim Hall

In recent episodes, we’ve covered high-level issues, such as hiring best practices, novel, training, methods, design for manufacturing, highly accelerated, life, testing, and more. On this episode, we’re going to go back to the basics. What common problems are assemblers experiencing today? What are the basics of assembly best practices? Which problems seem to live in perpetuity?

To answer these and other questions, I’ve invited two of my favorite experts on to the show. If you’ve been in the electronics assembly industry for some amount of time, there’s little doubt you’ve heard of Phil Zarrow and Jim Hall. Phil has been involved with PCB fabrication and assembly for more than 36 years.

He is president and principal consultant of ITM Consulting. Jim Hall has been involved in the electronics assembly industry for the past 27 years. He’s a principal consultant and resident Lean Six Sigma Master Black Belt with ITM Consulting. He’s also an instructor in the Lean Six Sigma programs offered at Dartmouth College. Together with Dr. Ron Lasky, Phil and Jim designed the SMTA’s SMT Processes Certification Course. A couple of years ago, Phil and Jim published a book titled “Troubleshooting Electronic Assemblies, Tales from the Board-Talk Crypt.”

Mike Konrad talks to them more about that book later in this broadcast. Phil and Jim host the popular audio series “Board Talk,” a question-and-answer show hosted on the Circuit-Insight website. On their show, you’ll hear serious questions, and often comical but real answers.

 

RM 126: Moisture Mitigation Strategies with Dan Jenkins and Rob Lowery

Moisture. The industrial world has been fighting moisture since the beginning of the industrial world. From a general point of view, moisture leads to issues such as

• Mold and mildew
• Rust
• Wood rot
• Damage to building materials
• Microbial growth
• And so much more.

In the electronics world, moisture creates a host of reliability problems including:

• Popcorning
• Delamination of conformal coating
• Corrosion
• Electrochemical migration
• Adhesion degradation (such as on labels and glues)
• And more.

We wanted to dive into moisture mitigation, so Mike Konrad invited two guests to discuss this very topic. Dan Jenkins is sales manager and partner of the Steel Camel, an industrial solutions company specializing in corrosion and water intrusion control for fuel systems and industrial equipment. Prior to Steel Camel, Dan worked as consultant and instructor in the crane accident prevention industry. He has consulted to large organizations such as Shell Oil, and the United States Department of Interior. Dan earned an MBA from the University of South Florida and earned his BA in Industrial Arts / Technology from Cal St. University Chico and his Post-Secondary Teaching Credential from San Francisco State University.

 

Bob Lowry has bachelor's and master's degrees in chemistry. His experience includes 31 years as sr. scientist and lab manager for three integrated circuit manufacturing companies, where measurement of moisture and moisture control activities were a major part of services he provided. He has 20 years of experience consulting to the microelectronics industry on a wide variety of topics including materials analysis and measurements and methods of moisture control for electronic components.

RM 125: DFM Best Practices with Pride Industries’ Engineering Manager Andrew Williams

As all of you are well aware, Reliability Matters 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, no doubt you’ve had the experience of being asked to build a product that seems unbuildable. One example that rings true was the introduction of bottom terminated components or BTCs. BTC’s are marvelous components.

Because all the lead terminations are below the part, they permit 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.

Today Andrew Williams helps us understand what exactly DFM is. He is 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. He 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.
