In this issue, we discuss some of the challenges, pitfalls and mitigations to consider when designing non-standard board geometries. We share strategies for designing odd-shaped PCBs, including manufacturing trade-offs and considerations required for different segments and perspectives.

The Battle of the BoardsJanuary 12, 2023 | Patrick Crawford, IPC
Estimated reading time: 3 minutes
Last year, IPC held its first-ever design competition at IPC APEX EXPO in San Diego. PCB designers from around the world competed in a series of heats during the months before the show, culminating in a showdown on the show floor between the top three finalists. Rafal Przeslawski, now with AMD, took home the top prize last year.
This year, the competition is back for its sophomore year. I asked Patrick Crawford, manager of design standards and related programs for IPC, to “layout” the details on the design contest, including lessons learned in 2022 and what’s new for the 2023 competition.
Andy Shaughnessy: Patrick, I see that the IPC Design Competition is returning for its second year. Give us the run down on this exciting event.
Patrick Crawford: It is indeed, and we’re happy that it’s coming back. As with last year, the IPC Design Competition is a venue for PCB design engineers to test their mettle. We have two heats of challenge, with the first heat occurring in Fall 2022, and the final heat onsite in San Diego in January. The first heat involves a full board buildup, where designers receive an electrical schematic, a BOM, and a scope of work. They then must input the schematic into their respective design tools and, after they work their magic, output a Gerber file package, assembly, and fabrication drawing. We choose the best three designs and designers, then invite them to compete in the finals heat.
The finals heat is a bit different from the earlier stages: We provide a nearly complete Altium Designer file, so the designers will only be responsible for placement and routing. We gave them exactly four hours in 2022, but for 2023, they get a little bit more wiggle room at five hours total, as we expect this year’s final challenge will require denser and more difficult routing. This isn’t a trivial ask; last year, while nobody took the full four hours, there was a lot of visible head-scratching and “Ah, yes, of course” facial expressions. We also had cast contestants’ design tools live via a screen share, so the audience was able to see what they were doing in ECAD in real time, which led to some fun commentary on the floor.
That brings me to a key change for this year’s finals. Instead of having the finals competition on the show floor like we did last year, we’re moving it out into the conference area—the same place where we have the standards development committee meetings. This will give us a bit more space to play around and do some fun things, like live-stream the event to Twitch.io and YouTube without the need for a sound-cancelling mic setup, etc. This way, we can reach a much wider audience through the power of the internet. However, it will be exciting to be where the action is and accessing that space will be easier this year because it’s free to attend our committee meetings.
Shaughnessy: That’s a great idea. What sort of PCBs will the competitors be laying out this time?
Crawford: For the preliminary heat, we provided a schematic for a gamepad—basically a controller for a hypothetical video game console. There’s some funky geometry to route around, and we’ve prescribed placement for some critical components, so they’ll have some constraints to work with. It’s a 10-layer board this year, and I think most people will go with a more traditional copper buildup, but we’ve given them the opportunity to use a 1+8+1 sequential buildup for microvias if they want. That’s something we didn’t do last year. The finals heat will also involve a game peripheral, but that’s all I’ll say for now. It’s top secret.

After working for a capital equipment supplier for almost 50 years, I’ve found that the most important part of getting to know your vendor is good communication among all parties. While contact between fabricators of a constantly changing product line and the designers of those products may occur daily or weekly, conversations between you and your equipment supplier may be years apart. That lengthy gap often means that previous contacts may have been promoted, retired, or moved on to other opportunities. You may have also migrated to a new supplier with whom you have little or no history. In either case, you will be interacting with someone you are unfamiliar with (as they are with you). Therefore, it is essential for both sides to communicate clearly so expectations will align.
The opening session of the second day’s conference proceedings focused on global PCB trends and was introduced and moderated by Dr. Michele Stampanoni, vice president of strategic sales and business development at Cicor Group in Switzerland. He opened the session with Dr. Hayao Nakahara’s knowledgeable and enlightening video presentation on the IC substrates industry.
The 2024 Winter Conference of the EIPC took place January 30 and 31 at the IHK Academie in Villingen-Schwenningen, Germany. The keynote session will be reported separately. Here is my review of the first day’s conference proceedings.
Electrodeposition comes down to fundamentals. In the early days of plating, many users considered the nuances of metallization as black magic. Those days are long gone. Having a thorough understanding of the critical parameters that influence electrodeposition will determine success.
