Rigid-flex Design Guidelines
Rigid-flex circuits are unique structures; part rigid board and part flex, they’re increasingly working their way into many of the electronic devices we use every day. There have been many advances in rigid-flex lately as more companies find themselves exploring this technology. So, before I started writing this article about rigid-flex design, I double-checked a few things. Fortunately, there is plenty of rigid-flex information available on a variety of great websites that we all know and trust.
I-Connect007 Editor’s Choice: Five Must-Reads for the Week
This week has been chock full of news about upcoming trade shows and conferences. Clearly, the season is upon us. This week, I-Connect007 reported on PCB West in Santa Clara (often referred to as the show which kicks off trade show season) and the topic of artificial intelligence was everywhere. By the looks of it, not just at the conference, either. For months now, the mainstream media has been gobbling up all sorts of news about generative AI engines, painting the picture that we’ll all lose our jobs to these tools, while also reporting on situations where the results from AI have gotten progressively worse over time.
Rigid-flex Stackup: It’s a 3D World
Z-zero founder Bill Hargin has been studying stackup design techniques for years. He developed the company’s PCB stackup planning software, and he wrote an I-Connect007 eBook, The Printed Circuit Designer’s Guide to… Stackups: The Design within the Design. In this interview, Bill shares his thoughts on designing rigid-flex stackups, the challenges they bring, and what rigid board designers need to know about designing stackups in 3D. “Flexperts” Mark Finstad of Flexible Circuit Technologies and Nick Koop of TTM Technologies also offer insight into the many tradeoffs that rigid-flex designers face.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week
This week has been both speedy and newsy. Of course, those two characteristics often seem to travel as a pair, don’t they? A four-day week here in the United States, accompanied by a wave of high-impact news from a wide variety of sources, would suggest that readers could be expected to spread out all over the news map. Not so much, judging from readership numbers; folks all found their highest value in the same type of news coverage. This week's list of must-reads is dominated by market reports as a result of that focused readership. On our list, we have PCB fabrication and EMS book-to-bill reports, a 10-year market forecast report, and a supply chain sentiment report. In addition, readers flocked to the EWPTE show coverage. Finally, we saw significant reader interest in the most recent podcast on sustainability in our logistical operations.
Selecting Flex Materials: Do Your Homework
While the layout of the circuit gives us much of the electrical characteristics of the design, your choice of materials can affect the mechanical and electrical characteristics of the circuit. Material choices affect not only the design of the circuit for its environment, but also the manufacturing and assembly processes. While the layout of the circuit gives us much of the electrical characteristics of the design, your choice of materials can affect the mechanical and electrical characteristics of the circuit.
Challenges of DFM Analysis for Flex and Rigid-flex Design, Part 2
Everyday rigid FR-4 PCBs have a well-known layer stackup recipe: dielectrics, PCB conductor layers, plane layers, mask, and silkscreen (nomenclature or legend). More advanced layer types may include embedded or screened components or cavities with bonded bare die. Flex and rigid-flex stackups include those similar to rigid PCBs, such as dielectrics, conductor, mask, and silkscreen layers, but that is where the similarity ends. There are many additional layer types present for this genre of PCB. They include types like coverlay, adhesive, conductive film, conductive foil, conductive adhesive, bondply, and stiffener.

RF Antenna Design and Layout Tips for Your PCB
These days, it’s hard to think of a consumer product that doesn’t contain an antenna. Even my garage door opener can connect to my phone via Bluetooth or Wi-Fi. Each time a new RF antenna gets added to a PCB layout, it can create a new headache for RF designers, especially as analog design skills start to become critical again. With so many RF capabilities being added to new PCBs, how can designers ensure the signals in their system are not corrupted and signal integrity is preserved?
I-Connect007 Editor’s Choice: Five Must-Reads for the Week
How was your week? We’ve been pretty busy ourselves, bringing you coverage of the SMTA Expo & Tech Forum in Boise, Idaho. Tabletops shows like this offer a great value during the spring, in between the bigger shows like IPC APEX EXPO and SMTA International. In fact, SMTA schedules approximately 30 regional shows around the United States and abroad.
DFM Analysis for Flex and Rigid-flex Design, Part 1
Flex and rigid-flex PCB constructions are not new concepts. It has become commonplace as engineers look for alternative circuit packaging for ever-shrinking electronic products. A flat, one-sheet schematic for a straight ribbon cable is analogous to its physical flat substrate. A flat, multi-sheet schematic that details circuitry for a rigid-flex design bears little visual resemblance to its three-dimensional, variable material rigid-flex assembly. However, in both schematic examples, schematic-based analysis tools are applied equally. This same truth also applies to common FR-4-based two-layer or multilayer PCBs.

Don't Blink: The IPC APEX EXPO Time-lapse
It’s a tradition here at I-Connect007 to set up a time-lapse for IPC APEX EXPO. There’s something satisfying, mesmerizing even, to watch the show floor build out and see the moment when the doors open and visitors fill the exhibit hall. Based on what others have said over the years, I know I’m not the only one whose favorite part is when the carpet gets rolled out and the whole character of the exhibition changes. This time lapse starts on the Saturday prior and continues through the Thursday tear-down phase.
IPC APEX EXPO Wrap-up
IPC APEX EXPO 2023 is over, and I think it was a successful show no matter how you slice it. There was barely a break in traffic on the show floor on Tuesday and Wednesday, and even on Thursday I saw people sprinting to close one more deal. Some committee meetings had nearly 200 participants; the meetings I sat in on were anything but boring.
