Optimization has become an important goal within the electronics assembly industry. While modern electronics assembly techniques utilize a variety of equipment, one specific type of equipment often consumes a disproportionate percentage of the overall equipment budget, that is the place machine. The cost of the machine, associated conveyors and feeders, require that the machine is running as often as possible.
The airline industry refers to this as “wheels up” time. Airlines make money when the aircraft is in the air “wheels up.” On the other hand, anytime the wheels are down, the aircraft is not making money for the airline.
I listened to an interview a few years ago with the CEO of Southwest Airlines, a US discount carrier. Unlike most other airlines, Southwest does not charge its customers to check bags. The CEO was asked by the reporter why they have not joined the rest of the industry in charging for checked bags. The CEO's answer was genius. If Southwest Airlines began charging for check bags, it would actually slow the boarding process as more and more passengers would drag their bags onto the aircraft, most likely resulting in a number of those bags having to be checked at the gate.
Southwest Airlines is famous for having the fastest aircraft gate turns in the industry, frequently under 30 minutes. Yet, if Southwest Airlines charged for checked baggage, it would require more time at the gate before the next flight would be ready to depart. That would result in fewer flight segments per aircraft per day. In other words, allowing customers to check bags for free equates to more “wheels up” time and, subsequently, more profit for the airline.
The same principal can apply to pick-and place machines. When pick-and-place machines are running product, they are making presumably making money. When they sit idle, they are arguably costing money. What can assemblers do to improve the optimization or “wheels up” time on their pick-and-place machines?
Mike Konrad's guest, Larry Welk, believes he has an answer. Welk, a.k.a. Professor Splice, is coowner of Smart Splice, a manufacturer of tape splicing tools.
Welk reviews tape splicing best practices and explain how tape splicing, when performed correctly, can lead to higher pick-and-place machine optimization.
So, buckle your seatbelt: this podcast episode is officially wheels up!

Today, we delve into an increasingly critical aspect of technology and electronics manufacturing - the pursuit of environmentally responsible electronics manufacturing. Our industry has witnessed many environmental revolutions.
The elimination of popular cleaning solvents brought on by the Montreal Protocol in 1989, soon followed by strict VOC regulations pertaining to cleaning chemicals.
The switch from lead-based solders to lead-free alloys, led by the Restriction of Hazardous Substances Directive, known as RoHS, implemented within the EU in 2003 and adopted nearly worldwide, regulations regarding the disposal of electronic waste (e-waste) resulting in many countries mandating regulations and programs for the safe recycling and disposal of electronic products, and more.
These regulations and others have inspired some companies to seek eco-friendly alternatives to traditional printed circuit board (PCB) fabrication.
The combination of numerous environmental regulations has resulted in many companies’ implementation of sustainability programs.
As our world becomes more connected, the demand for electronic devices continues to rise, and with it, the importance of mitigating the environmental impact of their production.
On this episode of The Reliability Matters Podcast, Mike Konrad speaks with Mark S. Edwards. Mark wrote an article entitled “Environmentally Responsible Alternatives to Traditional PCB Fabrication.”
He works as a strategic account manager within MacDermid Alpha Electronics Solutions, on the global Business Development team for Circuitry Solutions. Mark has been involved in electronics manufacturing since the late 1980s and brings a passion for process automation, circuit assembly, solders/fluxes, adhesives, coatings and PCB fabrication – all with a focus on repeatability and reliability.
Edwards holds a B.S. degree in mechanical engineering technology from Oklahoma State University and began his career at a defense electronics company in Dallas, Texas, that was later acquired by Raytheon.
He has uncovered trends and synthesized customer needs for electronic hardware in the telecommunications, defense, automotive, industrial controls segments in the Americas, and now globally, in his newest role.

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.

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.
