The Signal Integrity Issue: Design007 Magazine September 2025
September 9, 2025 | I-Connect007 Editorial TeamEstimated reading time: Less than a minute
During the dotcom boom, SI seemed a lot like black magic. Until then, PCBs ran at such low speeds, and rise and fall times were so long, that designers didn’t have to worry about “analogish” behavior. You could ballpark it and get away with it.
Today’s PCB designers have far more weapons to wield in their fight for SI than they did in 1999. That’s a good thing, because almost everything on a board is faster, smaller, and more complex than a few decades ago. As the saying goes, “If you don’t have signal integrity problems now, you will eventually.”
This month in the September issue of Design007 Magazine, our experts share a variety of design techniques that can help PCB designers and design engineers achieve signal integrity.

The Shaughnessy Report: A Plan for Floor Planning
08/11/2025 | Andy Shaughnessy -- Column: The Shaughnessy ReportMost of the time, we cover topics that designers say are giving them trouble. But designers don’t usually cite floor planning as one of their bigger challenges. No, it’s the fabricators who say that floor planning is an ongoing problem for their designer brethren, usually after having to put yet another job on hold.
Elementary Mr. Watson: Closing the Gap Between Design and Manufacturing
07/23/2025 | John Watson -- Column: Elementary, Mr. WatsonModern PCB designers are not merely engineers or technicians. I believe that PCB design, at its core, is an art form, and modern PCB designers should be considered artists. Beyond the technical calculations and engineering rules lies a creative process that involves vision, balance, and a passion for what we do. Like any artist who works with brush and canvas or chisel and stone, a PCB designer shapes invisible pathways that bring ideas to life. Each trace, layer, and component placement reflects thoughtful decisions that blend form, fit, and function.
