Rigid-flex: Designing in 3D
In this month’s issue, our expert contributors share their best tips, tricks and techniques for designing rigid-flex circuits. If you’re a rigid board designer considering moving into the 3D world of rigid-flex, this issue is just what the doctor ordered!
Simulation, Analysis, and AI
Getting today’s designs “right the first time” is critical, especially with costly advanced PCBs. Simulation and analysis software tools can help you in the fight to eliminate respins. They’re not magical, but they can predict the future of your design.
Advanced, Complex & Emerging Designs
This month, our contributors focus on designing PCBs with advanced, complex and emerging technologies. We investigate design strategies for boards that are on the cutting edge of technology, or crazily complex, or so new that designers are still writing the rules as they go.

A New Materials Paradigm
As you’ll see in this month’s issue of Design007 Magazine, slash sheets such as IPC-4101/126 were never meant to be used by designers when comparing PCB laminates. These documents were created to facilitate communication between purchasing and customer service departments. You could say that slash sheets are made for administrative purposes, not engineering.
As the captain said in 'Cool Hand Luke,' “What we’ve got here is a failure to communicate.” IPC does offer several design guidelines, created specifically for PCB designers, including one just for flexible circuits. But there isn’t such a guideline for high-speed designs.
Our expert contributors examined the development of IPC slash sheets and suggest that there is a need for new, robust material guidelines created specifically for PCB designers.
We also discuss the dangers of over-specifying materials, particularly for offshore manufacturing, as well as the many risks and trade-offs associated with laminate selection.
The practical question around CHIPS Act development and electronics assembly is, “Will this change how we do business?” Indium Corporation’s Dr. Andy Mackie sat down with Nolan Johnson to share what he sees as emerging answers to that question from his perspective as an expert in electronics assembly and packaging, and as a participant in standards development through IPC, JEDEC, and SEMI.
IPC continues to collaborate with the electronics manufacturing industry to meet their current and future workforce training needs.
Though product demand weakened this month with Orders and Backlog Indexes slipping, overall electronics industry operations remain healthy per IPC’s September 2023 Global Sentiment of the Electronics Supply Chain Report.
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.
