Words of Advice: Flex Design Challenges


Reading time ( words)

In a recent survey, we asked the following question: What are your biggest problems related to flex design? Here are just a few of the answers, edited slightly for clarity.

1. The signal integrity of signal paths through both flex and rigid parts of rigid-flex PCBs.

2. Understanding how to design a flexible PCB that is easily manufacturable and robust. 

3. None. We design them correctly!

4. Mechanical dimensioning and sizing to fit the required application.

5. Our designers need to learn more about the FPC fab process.

Why We Simulate

04/29/2021 | Bill Hargin, Z-zero
When Bill Hargin was cutting his teeth in high-speed PCB design some 25 years ago, speeds were slow, layer counts were low, dielectric constants and loss tangents were high, design margins were wide, copper roughness didn’t matter, and glass-weave styles didn’t matter. Dielectrics were called “FR-4” and their properties didn’t matter much. A fast PCI bus operated at just 66 MHz. Times have certainly changed.

Bridging the Simulation Tool Divide

04/12/2021 | I-Connect007 Editorial Team
Todd Westerhoff of Siemens EDA recently spoke with the I-Connect007 Editorial Team about the divide between users of high-powered enterprise simulation tools and those who need a more practical tool for everyday use, and how Siemens is working to bridge the gap. Todd also shared his views on why so many engineers do not use simulation, as well as advice for engineers just getting started with simulation tools.

Barry Olney’s High-Speed Simulation Primer

04/09/2021 | I-Connect007 Editorial Team
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.
