What's been going on at the factory while we've been away? Chris catches up Melissa and all of you listeners on all of the new people, machines, and processes that have been introduced during our break.
Ep.63:ESD Flooring w/ SelecTech CEO Tom Ricciardelli
After a LONG hiatus, we're back! Our break was for a very good reason though. Listen to find out why!
In this episode, we welcome SelecTech CEO and co-founder Tom Ricciardelli. Tom is a technical flooring expert on static control or ESD flooring. He is also chairman of the committee formed by the ESD Association (www.esda.org). His company, SelecTech, is a leader in the manufacture of innovative flooring products and has a very interesting story on how it came to be.
Tom gives us a quick recap on what ESD is (we also have a full overview episode on ESD) and discusses the importance of having an ESD-protected floor. We also talk about what the ESDA is, LEED certification and sustainability, as well as a very meta pet peeve.

Ep.62:Soft Skills of Engineering w/ Being an Engineer Host, Aaron Moncur
This week we're joined by fellow podcast host Aaron Moncur who runs the Being an Engineer Podcast and is also the founder of Pipeline Design and Engineering.
We had a fun discussion on the soft skills of engineering, including how to have systems in place that align with/support your goals, time management, and productivity hacks you might find useful for managing yourself and your team.
Pipeline partners with medical & other device engineering teams who need turnkey equipment such as cycle test machines, custom test fixtures, automation equipment, assembly jigs, inspection stations, and more.
Ep.61:How Small Manufacturers Manage Large Volume Orders
How do smaller manufacturers like Worthington and CircuitHub manage larger volume orders? Recently we've seen a big increase in these types of orders so it only seemed fitting to have a discussion about it. We briefly touch on the financial and negotiation side of things before getting to the logistics of how we handle large-volume orders. This includes how we decide if we're going to build and/or ship in batches, how large orders change how we buy parts, and why building this can be a very successful way of producing boards.
Ep.60:What Happens After the CHIPS Act w/ the Printed Circuit Board Association of America
We're back after a bit of a break! In this episode, we're excited to welcome David Shield from the Printed Circuit Board Associated of America (PCBAA) to talk about how their work is influencing the US Congress to bring electronics manufacturing back to America.
The Printed Circuit Board Association of America is the sole association of U.S. domestic printed circuit board manufacturers and suppliers. PCBAA was established in 2021 by PCB manufacturers and other industry stakeholders amid rising geopolitical challenges.
PCBAA seeks to promote an environment in which U.S.-based printed circuit board (PCB) manufacturers can thrive.
The PCBAA was formed to respond to the misunderstandings in the Chips Act. David explains to us what exactly the CHIPS Act is, what sort of impact might the efforts of the PCBAA have on people within the United States hiring a company like Worthington to order their circuit boards, and more.

Ep.59: Even Cleaner Cleaning With Cleaning Expert Mike “Mr. Clean” Konrad
We're very excited to have Mike Konrad, founder of Aqueous Technologies as well as host of his own podcast, Reliability Matters, back on the show.
We first had Mike on the show to discuss the history of board cleaning, the electronics the industry's transition to primarily using no-clean flux, and why more and more companies are reintroducing board cleaning back into their assembly process.
Mike recently reached out to us and offered to talk about the 2018 changes to the IPC cleanliness standards and why adoption of the new standard has been slow at best due to the lack of understanding of the standard's details. We of course jumped at the opportunity...
We hope you enjoy this episode that is most definitely more entertaining than watching grass grow.

Ep.58: The Benefits of Asynchronous Design Review for Engineers & Manufacturers w/ AllSpice.io
This week we are joined by Valentina Ratner and Kyle Dumont, co-founders of AllSpice.io. Valentina and Kyle met while doing an MBA program at Harvard and realized they both shared a common frustration - the lack of asynchronous design review tools available for electrical engineers despite such tools being readily available for other engineering fields like mechanical and software. Thus they joined forces to create AllSpice.
AllSpice is a git platform for hardware engineers that helps them to accelerate their time to market by enabling modern revision control and collaboration for native electronic designs.
We had a great time having them on the show to learn more about AllSpice as well as Valentina's hatred of sharp-edged rectangles.

Ep.57:Outer Layer Imaging w/ CAM Engineer Dave Wilcox
CircuitHub CAM engineer, Dave Wilcox is back on the show to teach us more about the PCB fabrication process. In our last episode with Dave, we went into the fine details of drilling a PCB. Today we move on to the next step Outer Layer Imaging.
Ep.56:Understanding Controlled Impedance w/ NCAB Group Field Application Engineer, Ryan Miller
We apologize for our extended break! Chris has been hard at work from morning til late at night every day setting up Worthington's two new Fuji pick and place machines. Now that some of the dust has settled we hope to get back on a more regular recording schedule.
We've had several requests from our listeners to have an episode on on impedance control, which is unfortunately a topic Chris and Melissa have little expertise on. Fortunately we were able to connect with Ryan Miller from NCAB group who specializes in the subject and kindly agreed to come on the show to give us a lesson on what impedance control is, in what situations is it necessary, and more.
Ep.55:How PCB panelization methods inform depanelization
In episode 19, we focused on the different types of depanelization methods that can be used during assembly. In this episode, we take a deeper dive into panelization, how we decide what panelization methods and sizes to use, and how this informs depanelization.
Ep.54:A Conversation with The Awkward Engineer
In this episode, which might just be our nerdiest one yet, we are joined by Sam Feller, aka The Awkward Engineer. First and foremost he would like everyone to know that he is the awkward one, the engineering is top notch.
Sam is a long time Worthington/CircuitHub customer, product manager at Tulip, former engineer at Amazon, and founder of the Awkward Engineer where he works on quirky hardware project and now does consulting!
It was a pleasure to have Sam on the show. Some of the topics we touch on include:
Why having common stock parts set up on reels is not actually the simplest idea to execute.
Interesting sourcing stories.
Soldering techniques for building prototypes
The importance of having structured processes in place for your hardware of software development team .
Sam's vickrey auction for his Voltmeter Clocks
If you want to get in touch with Sam you can email him at questions@awkwardengineer.com
Ep.53:The nitty gritty details on solder
We're back! In this episode we talk about what we were busy doing on our "break", the different types and formats that solder comes in, and some unfortunate consequences that sometimes occur while eating chips.
Ep.52: All the Tricks and Gotchas in Surface Mount Assembly (Repost from the Coriolis Effect)
Last week Chris was a guest on the Coriolis Effect, a podcast hosted by Bil Herd and Ben Jordan. Since we are still on hiatus (and because the episode was so great) we decided to repost the conversation.
Don't worry, we expect to be back next episode with some new, fun and content and plenty of pet peeves!
Ep.51: Custom tooling to the rescue
Sometimes things are difficult to build....enter the help of custom tooling! In this episode, we highlight some of the applications for which we might order custom tooling, how they can help us assemble boards more efficiently and accurately, and some things you might want to do if you'd like to avoid custom tooling becoming necesesary.

Ep.50: Benefits of intrusive soldering
Intrusive soldering, also known as pin-in-paste, is a method that uses solder paste to solder the thru-hole leads instead of hand soldering, wave soldering, or selective soldering. If designed properly, it's a great way to save time and money during pcb assembly. In this episode, we discuss how intrusive soldering is done, challenges associated with this process, and design recommendations.

Ep.49: The role of flux in PCB assembly
Flux is friend. Not foe.
To create a solder joint, you have a lot working against you. Boards, parts, the air...it’s all very cold compared to the melting point of solder. Those are easily overcome with a good heat source in the way of a soldering iron, wave solder, or selective solder. However, none of this will do you a lick of good without flux because metal oxide is the biggest challenge you have to combat.
In this episode, we go over flux's role in fighting the oxide layer that forms during PCB assembly, the basic chemistry of flux, what cold solder joints are, and more.
Ep.48: Debugging PCB Assemblies
It's a fact of life that defects and failed boards will sometimes occur, which is why it's so important to have a debugging procedure prepared to help your CM know how to move forward. In this episode, we talk about best practices on how to work with your CM when these problems arise.
Ep.47:Advanced Drilling w/ CAM Engineer, Dave Wilcox
We've finally managed to convince CircuitHub CAM Engineer, Dave Wilcox, to come back on the show to continue our series about the intricacies of PCB fabrication. If you're just tuning in, we recommend you listen to our episodes about Inner Layer Production and PCB Drilling Basics before this one.
In this episode, we cover some of the finer details of PCB drilling including what the drilling setup physically looks like and tips you can implement to save your PCB fab time. We also learn that Melissa really needs to work on her email management setup.
