    The Return of Cleaning: Why Post-Reflow Cleaning Is Becoming Mainstream Again (Part 2) - Episode 194

    This is part two of a two-part series. In Part One, we explored how the electronics industry transitioned from a clean-everything approach to one where cleaning became optional. But what happens when the assumptions behind “no-clean” collide with modern electronics design? In this episode of Reliability Matters, Mike Konrad examines how the definition of cleanliness has fundamentally changed. As assemblies became smaller, denser, and increasingly deployed into harsh environments, the industry discovered that historical cleanliness standards were no longer sufficient to predict real-world reliability. Modern low stand-off components like QFNs, BGAs, and CSPs create tight geometries where residues can become trapped and difficult to remove, while thermal cycling and internal condensation can create localized harsh environments inside the product itself. This episode explores: • Why IPC moved away from fixed cleanliness limits • The growing importance of SIR and ROSE testing • Why “cleanliness” is now tied to risk, not a number • How internal condensation can trigger electrochemical migration • Why no-clean flux has become the most commonly cleaned flux type in the industry • The return of cleaning as a mainstream reliability process • Why modern assemblies require aggressive spray-in-air cleaning technologies instead of historical immersion-based vapor degreasing methods • How diffused spray patterns improve cleaning beneath low stand-off components Mike also explains how modern cleaning challenges are no longer just about chemistry. They are about physics, fluid delivery, and whether the cleaning process can physically reach contamination hidden beneath today’s densely packed components. As electronics continue to shrink and reliability expectations continue to rise, one question becomes increasingly important: Clean enough for what? If you work in electronics manufacturing, reliability engineering, process engineering, or quality assurance, this episode provides a detailed look at why post-reflow cleaning has once again become a critical part of modern electronics manufacturing.

    The Return of Cleaning: Why Post-Reflow Cleaning Is Becoming Mainstream Again - Episode 193

    This is the first of a two part series. For decades, cleaning circuit assemblies after soldering was not optional. It was standard practice across the electronics manufacturing industry. Then, almost overnight, that changed. In this episode of Reliability Matters, Mike Konrad takes you back to the origins of that shift. From the widespread use of CFC-based cleaning solvents to the global impact of the Montreal Protocol, this episode explains how environmental regulation led to the rapid adoption of no-clean flux and the removal of cleaning as a standard process step. But that decision came with assumptions. Assumptions based on larger components, wider spacing, and assemblies that were far more tolerant of residues than what we see today. As electronics evolved, so did the risk. Miniaturization, increased component density, and the expansion of electronics into harsh environments have dramatically reduced the tolerance for contamination. And when cleaning was removed, it wasn’t just flux that remained. It was the totality of residues introduced throughout the manufacturing process. This episode walks through how those residues, combined with moisture and electrical bias, can lead to electrochemical migration, including parasitic leakage and dendritic growth, often resulting in delayed or intermittent failures. This is the story of how we got here. In Part 2, we bring this discussion into the present. What does “clean” actually mean today? Why did the industry move away from fixed cleanliness limits? And why is cleaning once again becoming a critical part of modern electronics manufacturing? If you’ve ever asked the question, “Do I really need to clean?” Part 2 will challenge how you think about the answer.

    An Academic Look at Al in Electronics Manufacturing: Where It Works, Fails, & Why It Matters - # 187

    Artificial intelligence is being promoted as the next revolution in electronics manufacturing, but what happens when the people evaluating it aren’t traditional AI experts, aren’t software vendors, and aren’t selling anything?  Today’s conversation brings together engineers and professors who live at the intersection of education, reliability, and real-world manufacturing to separate meaningful progress from speculation. Each episode brings together engineers, researchers, and industry leaders to examine best practices, emerging technologies, and real-world lessons, always with a focus on data, physics, Best practices, and long-term performance. Today’s episode is a little different—and the setting couldn’t be better. I’m recording live from the Big Island of Hawaii, in Kona, at the SMTA Pan Pacific Strategic Electronics Symposium, better known as PanPac. At PanPac, academia meets industry in a way that’s truly unique. Leading international universities join forces with CEOs, inventors, senior engineers, and decision-makers from around the world.  This is where the brightest research collides with the most pressing industry challenges — and sparks solutions that drive the future of electronics. I’m honored to be the conference chair, especially on this 30th anniversary of PanPac. This episode is all about “AI in Action: Progress, Pitfalls, and the Future of Electronics.” Artificial intelligence is becoming a frequent topic in electronics manufacturing—from inspection and process optimization to predictive maintenance and reliability modeling.  But rather than approaching this conversation from the standpoint of AI evangelists or software developers, we’re taking a different path. My panelists are: Eva Hymes, Hayden Lee, Dr. Ron Lasky, Dr. John Evans, and Dr. Pradeep Lall.  None of today’s panelists claim to be AI experts. Instead, they are engineers and professors who sit at the intersection of education, engineering, and real-world manufacturing challenges. Their perspective is grounded in physics, data, reliability science, and decades of experience teaching the next generation of engineers—many of whom will be working alongside AI-driven tools whether they choose to or not. Because all of our panelists come from academia, this conversation intentionally steps back from hype and buzzwords. We’ll focus on how AI is actually being used, where it shows promise, where it introduces risk, and where critical gaps still exist—especially in high-reliability electronics manufacturing. And because PanPac serves the electronics manufacturing community, we’ll keep this discussion connected to the factory floor, workforce readiness, education, and long-term product reliability.  We’ll also touch on broader societal questions, including how AI is shaping engineering education and professional intuition. So if you’re looking for a grounded, thoughtful discussion on AI—one rooted in engineering reality rather than marketing claims—this episode is for you.

    Readiness Through Repair: How the U.S Military is Strengthening Capabilities with Right to Repair - Episode 186

    If a $26,000 drone repair can be done in the field—but policy says it has to be shipped back to the manufacturer, do you really have a reliability problem… or a repair access problem? Today on the show, I’m joined by William Santos, International Sales Manager at ABI Electronics and a global advocate for the Right to Repair movement. William recently wrote a compelling article titled “Readiness Through Repair: How the U.S. Military is Strengthening Capabilities with Right to Repair,” where he explores how repair access—or the lack of it—directly impacts mission readiness, lifecycle cost, and operational resilience within the U.S. military. For decades, highly trained military technicians have been prevented from repairing mission-critical equipment due to restricted access to diagnostic tools, software, and spare parts. That model is now being challenged.  In April 2024, the U.S. Army announced plans to embed Right-to-Repair provisions into both new and existing contracts—a major shift with enormous implications for reliability, sustainment, and cost control. Today, we’ll unpack what this policy change really means, why repair capability is inseparable from readiness, and what lessons commercial industry can learn from the military’s pivot toward repair empowerment.
