  • RM 138: Hand Soldering and Rework Best Practices

    Today we're diving deep into the world of precision and craftsmanship—two crucial elements in the realm of hand soldering and rework of circuit assemblies.


    Whether you're a seasoned electronics enthusiast, a hobbyist, or just someone with a curious mind, this episode promises to demystify the art and science behind hand soldering and rework. We'll be exploring the latest tools, techniques, and trends that define this intricate process, shedding light on the unsung heroes who meticulously bring circuit assemblies to life, or in the case of rework, back to life.

    There is archaeological evidence that soldering was employed as early as 5,000 years ago in Mesopotamia. Soldering and brazing are thought to have originated very early in the history of metal-working, before 4,000 BC. Sumerian swords from 3,000 BC were assembled using hard soldering techniques.

    While soldering applications have morphed and expanded over the centuries, the basic “rules” of soldering have not. On this episode, we’re going to talk about an obvious soldering application, at least to my audience, and that’s soldering of electronic assemblies.

    From the evolution of hand soldering with numerous technological advancements to the challenges faced by DIYers and professionals alike, we've got it all covered, thanks to Mike Konrad's subject matter expert guest, Debbie Wade. 

    Wade is managing director of ART A-R-T, Advanced Rework Technology, a fully independent training organization, which has been presenting various training courses for over 30 years. She has been in the electronics industry for over 20 years with the last 15 of those years at Advanced Rework Technology. 

    Wade comes to us well-credentialed. She chairs the IPC-A-620 Training Committee and IPC European Training Committee, and with her Master IPC Trainer status for IPC-A 600, 610, 620, 7711/21 and J-STD 001 is an expert in the field of fabrication, assembly, process and acceptance of board and cable assemblies. 

    She has been presented with numerous awards from IPC in recognition of her contribution to IPC standards and training courses.

    So, grab your soldering iron (metaphorically speaking), get ready to dive into the flux, and join us as we unravel the secrets of successful hand soldering and rework. Stick around for valuable insights, practical tips, and maybe even a few stories from the trenches of hand soldering and re-work.

  • PCB Chat 126: Andrew Scheuermann on AI in Electronics

    Artificial intelligence is perhaps the most discussed – and least understood – topic in technology today.

    We in electronics design and manufacturing know, of course, that automation is part and parcel of what we do. But while the landscape has changed, be it the transition from mechanical drawings to CAD tools with their autorouters, or from manual and semi-automatic printers and placement machines to lights-out factories where cobots have replaced operators, the industry still has a long, long way to go in terms of widespread implementation of AI, or even understanding what it all means.

    Andrew Scheuermann joins Mike Buetow to share some perspective on this emerging technology. Scheuermann, along with his business partner Tim Burke, is cofounder and CEO of Arch Systems, a Silicon Valley-based developer of software tools that collect raw machine data and use predictive analytics to calculate manufacturing key performance indicators, or KPIs.

    Scheuermann has published numerous scientific papers in the areas of semiconductors, electronics manufacturing, and renewable energy. He has a Ph.D. in Materials Science from Stanford, and is also part of StartX, a startup accelerator for company founders who are affiliated with Stanford that has invested over $200 million across various companies, including 13 now valued over $1 billion.

  • RM 133: Novel Wireless / Wearable ESD Monitoring

    We are all aware of the damage electrostatic discharge can wreak on components and electronic products. We mitigate ESD damage through various forms of monitoring. We wear wrist and heel straps, stand on ESD-safe flooring, utilize ESD workstations, and more. We even have ESD testing locations that will test a human standing on a specialized testing station. But what happens the moment that person steps off the tester?


    My guests today are Dr. Daan Stevenson and Dr. Jonathan Tapson of IONA Tech, a manufacturer of a novel wearable ESD monitoring device that provides constant real-time ESD monitoring.

    Normally, we don’t talk about specific products on the show. We usually limit our conversations to best practices. This is a bit of an exception to rule. From time to time, a product is introduced that is so novel, it's worthy of a conversation. And that’s the case here. 

    Dr. Daan Stevenson is chief executive officer of IONA Tech. Dr. Stevenson has a background in mechanical and aerospace engineering. During his doctoral research, he studied the high voltage charging of spacecraft, which are electrical capacitors in the same way that the human body is. While working to design an automated ground station for UAVs, he frequently damaged electrical components from electrostatic shocks. This motivated the creation of IONA Tech, with the goal of advancing technology in ESD mitigation.

    Our other guest is Dr. Jonathan Tapson, chief technology officer of IONA Tech. Dr. Tapson was professor of electrical engineering at Western Sydney University before moving to Colorado in 2016. He spent his early career conducting sensor and instrumentation research, with a strong industrial focus. During this time he spun out three companies from his research, all of which are successful today. His specialties include low-noise circuits and systems design, mechatronic design and the integration of machine learning into real-time systems.
