PCB Chat

This episode is a little different in two ways. First, host Mike Konrad recorded it not in his studio but at the SMTA Pan Pacific Strategic Electronics Symposium, affectionately known as PanPac, in beautiful Maui, Hawaii. Each year, Mike records a Reliability Matters podcast at PanPac. Normally, the format of the show is to ask questions and the guests provide answers. On this episode however, the guests do all the talking. The theme of this episode is Electronics: Down Memory Lane and a Vision for the Future. The guests on this episode share their view of the history of electronics from three different perspectives: Dr. Ron Lasky, Dartmouth College Dr. John Evans, Auburn University Dr. Tom Duval, Auburn University. They share their perspectives on the history of the electronics industry in presentation format. This episode contains three short PowerPoint presentations, which can be viewed in the video version of this podcast: https://www.youtube.com/watch?v=HlDYgZ6Hv6w

Supply chain management looms over everything we do, but it has been more pronounced than ever over the past five years as the Covid pandemic steered so much attention to how we procure and inventory parts.  About a month ago, DigiKey, one of the largest distributors of electronic components in the world, and EMA Design Automation announced the integration of DigiKey's myLists tool with EMA UItra Librarian's UltraBOM bill of materials management software. The benefit, they say, is that designers and engineers will have access to DigiKey's parts within their OrCAD Capture environment and can then seamlessly send a bill of materials to DigiKey. Gopu Achath, vice president of technology at EMA Design Automation, and Cody Walseth, digital product owner at DigiKey, join Mike Buetow to discuss the new collaboration.

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.
