The Standards of Design
Our expert contributors discuss how PCB designers can utilize standards to save time and money, not to mention frustration. We also spotlight the newly updated version of the IPC Checklist, a handy guide that illustrates which standards cover which topics, from front-end design through assembly.

Changes on the Horizon: Is Resistance Futile?February 10, 2022 | Stephen V. Chavez, PCEA

For printed circuit engineers, especially those of us who have been in the industry for some time now, change is inevitable. From customer requirements that lead to design changes and deadlines being pulled in, to decreasing budgets and resource reallocations, change is one area where we must be adaptable if we want to survive and be successful in today’s industry.
Engineering change orders (ECOs), schematic/drawing redlines, component placement adjustments, and mechanical features modifications are among the changes that most of us usually deal with at one point or another during a project’s design cycle.
In my experience working for both small engineering firms and large OEMs, change typically translates into more time, which translates into more money. The big questions: Is the change billable or not? Who pays for this, or eats the cost of this change?
It all depends on how a contract was written, and how the purchase order (PO) was awarded. Potential changes are risk factors that are added into each quote, with a caveat that each change will be evaluated. This evaluation leads to a potential “out of scope” response to this change, adding an additional cost to the already agreed-upon PO, extension to the project schedule, or reset to the original project task duration. Every company handles purchase orders differently.
As I mentioned, change is inevitable in PCB design, and designers have become accustomed to it. But what about those other changes that may come at some point in our careers? Perhaps you’ve experienced a change in EDA tools, or a change in company culture, or both.
If so, you may have a special understanding of the famous motto of “The Collective” in Star Trek: Generations. “Resistance is futile.”
I feel your pain. Usually, this sort of change happens if you switch jobs, your company is acquired by another company, or your department is reorganized. It happens, and if it hasn’t happened to you yet, it probably will, if you remain in the industry long enough.

Cadence Signoff Solutions Empower Samsung Foundry’s Breakthrough Success on 5G Networking SoC Design12/01/2023 | Cadence Design Systems, Inc.
Cadence Design Systems, Inc. announced that Samsung Foundry successfully taped out a 5G networking SoC design on the Samsung 5LPE technology using the Cadence® Quantus™ Extraction Solution and Tempus™ Timing Solution.
There are many ways, dozens to be sure, and most likely many more, to streamline a PCB design. My goal here is to pick a single-digit number of rules to abide by, that can be reasonably adhered to, and provide some bang for the buck. These rules are meant to reduce design scope creep, avoid PCB respins, and improve production yields.
Hirose has expanded its low-profile DF51K wire-to-board connector series to include a surface mount technology (SMT) version. Compatible with automated assembly processes, including pick-and-place machines, the DF51K SMT Series simplifies the assembly process and saves significant manufacturing time and cost.
Siemens Digital Industries Software set the benchmark for innovation in the field of engineering simulation with the launch of two groundbreaking solutions - HEEDS™ AI Simulation Predictor software and Simcenter™ Reduced Order Modeling software.
I am, at heart, a die-hard “Star Trek” fan. When I was a kid, I was all about phasers, warp drive, and cool stuff like that. However, these days, I tend to put a higher value on production and storytelling. But like any fan (I’m avoiding “Trekkie” because, frankly, it’s kind of embarrassing), I have certain moments from the hundreds (if not thousands) of hours filmed for the various TV shows and movies that are among my favorites. One of those moments is in “Star Trek III, The Search for Spock,” when our heroes steal the Starship Enterprise from space dock.
