PCB Chat

Today we’re diving into a critical yet sometimes overlooked component that powers so many of the devices we rely on: batteries. Batteries are the heartbeat of countless electronic products, from medical devices and electric vehicles to consumer gadgets and industrial systems.  Choosing the right battery is not a one-size-fits-all decision. It requires a keen understanding of the application, performance needs, and environmental demands. The right selection can make the difference between a product that excels in reliability and one that, quite literally, fails to deliver.  But there’s more to batteries than just selecting the right chemistry or capacity. Safety is paramount. Poor battery selection, design, or management can lead to performance issues, overheating, or catastrophic failures. As we’ve all seen in headlines, battery malfunctions can result in recalls, damage to brand reputation, or, worse, safety hazards for users.   To shed light on this vital topic, we’re joined by an expert in the field of battery technology. Alex Norman is a Battery Management System Designer at Pro Technologies, a well-established and trusted custom battery pack manufacturer, providing engineering capabilities from concept through production. Their leading-edge manufacturing facility and headquarters is based in Pilot Mountain, North Carolina.   Alex has deep experience in Printed Circuit Board Design, Product Development, Battery Management Systems and more. Alex is also a content creator, focusing mostly on electronics, battery, and BMS content available on his LinkedIn page and YouTube channel. Today, we’re going to explore how to choose the right battery for your assembly, best practices for integration, and how to mitigate potential safety risks.   So, if you care about keeping your products powered, reliable, and safe, don’t bolt just yet – this podcast on batteries is positively charged with insights! Stick around and top off your battery knowledge!

Today’s guest intersects two key areas for electronics manufacturers: circularity and inventory management. "The cost of a component isn't just the cost of a component. It's the cost to the planet."   That's what Kenny McGee, chief executive of Component Sense, says. Component Sense is an Edinburgh, Scotland-based company that leads electronic manufacturers toward zero waste. It takes brand-new, perfectly good excess components and redistributes them to other manufacturers for use.  We talk about the market for recycled electronics, how major OEMs are circumventing European Union reuse and recycling laws, what companies can do with excess stock, and the horrific conditions at a reclaim dump in Agbogbloshie, Ghana, that inspired him to make a documentary. 

Today, we’re exploring a transformative topic: AI-based inspection technologies.    Artificial intelligence is revolutionizing how we detect, analyze, and address defects in the electronics assembly process, combining precision with unparalleled speed to unlock new possibilities for efficiency and reliability.

Supply chain issues are rearing their ugly heads -- again -- with the latest blow the decision by Nippon Denkai to close and liquidate its copper foil manufacturing plant in Georgia, the last such factory in the United States.  In Part 1 of a two part podcast, Geoffrey Leeds of Leeds AI joins Matt Leary (Newgrange Design), Geoffrey Hazelett (FreedomCAD) and Mike Buetow (PCEA) to discuss the supply chain situation and how the industry can adapt. Part 2 covers the semiconductor/packaging/PCB technology stack.  

Today, we’re diving into one of the most transformative innovations of our time: electric vehicles and the vast infrastructure needed to support their growth.  Joining host Mike Konrad is Brian O’Leary, global head of of e-Mobility & Infrastructure at Indium Corporation, a leading expert with deep insights into the electronic assembly industry and its critical role in the EV revolution. As electric vehicles continue to redefine the future of transportation, the reliability and scalability of the infrastructure that powers them—particularly public EV charging stations—have become pivotal challenges.  The electronics assembly industry is at the heart of these systems, from the semiconductors enabling fast charging to the sensors ensuring safe and efficient operation. However, with nearly 26% of public EV charging stations estimated to be nonfunctional at any given time, reliability remains a significant hurdle. This episode will explore the major reliability issues plaguing public EV charging stations, including power instability, component failures, and environmental challenges. How innovations in electronics design and assembly can address these challenges, from improving thermal management to leveraging advanced materials like those developed by soldering materials manufacturers. The exciting opportunities for the electronics industry to lead the charge in building a more resilient, reliable, and efficient EV infrastructure. Brian O’Leary brings a wealth of knowledge on how advanced materials, smart assembly techniques, and innovative designs can solve these pressing issues and accelerate the adoption of electric vehicles.  Together, we’ll review the technical challenges, explore solutions, and look ahead to the bright future of electric mobility.
