OM DENNE EPISODE
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.

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 Reli…
Tomachie has quite a few tricks up its sleeve. Its eponymous platform provides AI-assisted analysis of PCB schematic data. It optimizes DfT and identifies the ideal locations for physical test point insertion. And it generates a 0-100 layout-readiness score, providing design teams with an objective…
What if passing the test is not enough?
In reliability engineering, we often place a great deal of confidence in laboratory validation. We test, measure, analyze, and document. And when the product passes, we naturally assume it is ready for the field.
But what happens when a product passes the l…
Today, we’re going to explore a topic that seems to be touching nearly every industry, every workplace, and increasingly every part of our daily lives: artificial intelligence.
But this conversation is not just about what AI can do. It’s about what AI assumes, what it values, what it misses, and w…
