In this episode, we continue our conversation from last episode with Dave Wilcox, PCB CAM engineer at CircuitHub, to explore the intricacies of plugging and filling vias.
Topics Covered:
The differences between plugging and filling vias, and when to use each method.The common challenges faced during the reflow process, including the infamous "popcorn effect" caused by trapped flux.Practical advice on preventing manufacturing issues related to via plugging.Cost considerations between tenting, plugging, and filling vias.Insights into using various materials for via filling, including epoxy and solder.A fascinating case study on using solder to plug vias for gas sensors.The importance of thoughtful PCB design and silkscreen placement to avoid manufacturing headaches.Key Takeaways:
Plugging vias can prevent air and flux entrapment, but must be carefully specified in the design.There’s a delicate balance between cost and functionality when choosing how to handle vias.Thoughtful design and clear communication with manufacturers can lead to smoother production and better results.pickplacepodcast.com

In this episode, Chris and Melissa we are focused on the topic of tenting vias. Joined by our favorite PCB guru, Dave Wilcox, we dive into the thrilling question: is it "via" or "v-eye-a"? We discuss the technical details behind different types of vias, tenting methods, and the potential manufacturing challenges that arise from improper designs such as why covering one side of a via might just lead to a tiny PCB firework show. Make sure to look out for part 2 of this episode where we continue on to learn about plugging and filling vias.

In this episode we delve into the topic of RF (Radio Frequency) shields. . Chris explains the different types of RF shields—open top, closed top, and clip-based—detailing their applications, advantages, and challenges. We also explore the processes involved in placing these shields on circuit boards, emphasizing the importance of inspection and the complexities of manual versus automated methods, and discuss how to choose the best type of shields for your project. More importantly, Chris shares a detailed story about a poorly designed bathroom he recently experienced and realizes that one of his big pet peeves is thoughtlessness.

We like to talk to interesting people on this show so when Praxie reached out to us wondering if their CEO, Michael Lynch could come on the show we knew it would be a fun conversation.
Michael is the former head of Internet of Things at SAP software and now CEO of Praxie (and believe it or not, former lead in Les Miserables on Broadway prior to that!).
We talk about how Michael went from the acting/performance world to the internet of things and eventually wound up founding Praxie.
Praxie provides a platform that allows organizations to transform their workflows with AI-powered processes, dashboards, and applications, without spending an arm and a leg and taking months to complete. This is especially relevant for manufacturing businesses who are stuck using Excel spreadsheets and software from the 80s.pickplacepodcast.com

Why would we dedicate an entire episode to conveyers, you ask? Because it just so happens to be Chris' favorite topic! Chris has an addiction to progress and conveyers are one of the best ways in a factory setting to achieve that (both literally and figuratively). We get an overview of the different types of conveyers typically used in a factory setting and get into the technical aspects of how to set conveyers up before venting about the end of daylight saving time.

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.
