The Shaughnessy Report: The PCB Design Supply Chain


Reading time ( words)

It’s not a simple task providing you all with information you can use. Most of you are really good at your job, and you could design just about any type of board that your boss throws at you. And you should be good; most of you are—ahem—seasoned veterans of the PCB design world. At this point in your career, you have this stuff down to a science.

You’re probably not going to discover a brand-new way to design boards, but you know that there’s always something to learn in this job: new design tips and tricks, changes in PCB technology, market trends, and much more.  As the ol’ saying goes, “You learn something new every day.” We certainly do!

So, we occasionally look at other design topics that are not directly related to PCB design and layout techniques—markets, legislation, materials, education, etc. Is there designer interest in this topic? This is what happened when we surveyed our readers a few months ago.

We asked readers of The PCB Design Magazine if their supply chain was a problem for them. Almost two thirds of respondents said no, but a solid 37% said yes. And surprisingly, for many it was an emphatic “yes.” Navigating the supply chain is a huge challenge for some of our leading companies.

What sort of bugaboos were designers referring to? Long lead times, parts obsolescence, multiple component changes and ECOs…you name it. Some designers said the parts selection process on the front end is the worst part of the design cycle, and their companies have had to stock more and more hard-to-find parts. Redesigning boards with obsolete parts ranked high too.

Even worse, some respondents said that the supply chain was the one thing they could not influence, much less control. Comments such as “We’re dealing with idiots” were typical. How would you like to work in a situation like that? Maybe you are right now. You have my sympathy.

Barry Olney’s High-Speed Simulation Primer

04/09/2021 | Barry Olney, In-Circuit Design Pty Ltd
The I-Connect007 editorial team recently spoke with Barry Olney of iCD about simulation. Barry, a columnist for Design007 Magazine, explains why simulation tools can have such a steep learning curve, and why many design engineers are still not using simulation on complex high-speed designs.

Eliminating ‘Garbage In, Garbage Out’ With Checks and Balances

03/26/2021 | Nick Barbin, Optimum Design Associates
The proverbial saying “garbage in, garbage out” holds true in the electronic product development world. PCB designers stand squarely in the middle of a busy information intersection flowing with inputs and outputs. Missing or bad information at the beginning of a design project will undoubtedly lead to board re-spins, increased costs, and most importantly, a delayed product release. The same can be said about the PCB designer who doesn’t provide a fully checked and comprehensive data package to the downstream manufacturers, i.e., “throwing it over the fence.”

Turning ‘Garbage In, Garbage Out' into ‘Good In, Good Out’

03/23/2021 | Tamara Jovanovic, Happiest Baby
In the PCB design cycle, it is so easy to unintentionally introduce “garbage” into your system. Unless you have time to extensively check everything you bring in from an external source, it is very likely that something will not match up with your design data. In the end, this means you’ll have to put more work into your design and basically reverse-engineer a part that was supposed to save you time and effort.
