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.

April Issue of I-Connect007 Magazine: Beyond the Rulebook
04/14/2026 | I-Connect007 Editorial TeamIn this month’s I-Connect007 Magazine, we asked PCB designers, fabricators, and suppliers what it really means to operate without a rulebook. Their perspectives vary, especially between seasoned designers and experienced fabricators, but a common thread emerges: progress depends on pushing boundaries and finding a way forward, even when the path isn’t clear. In many ways, this mindset has always been part of what we do, whether we’ve called it that or not.
Marcy’s Musings: Operating Without a Rulebook
04/15/2026 | Marcy LaRont -- Column: Marcy's MusingsWhat happens when the rulebook is no longer useful, or worse, has not yet been written? With electronics innovation happening at warp speed, we’re increasingly asked to design and build what has no precedent, proven path, or tidy checklist to follow. “Design for invention” begins at the edge of known capability, where traditional DFM gives way to something far less certain, and far more exciting. It’s not about breaking rules for the sake of it; it’s about recognizing when the rules no longer apply and having the insight, collaboration, and courage to move forward anyway.
Connect the Dots: Designing for the Future of Manufacturing Reality—Solder Mask and Legend
04/09/2026 | Matt Stevenson -- Column: Connect the DotsPCBs seem to be getting more complex by the day, so it is important for designers to keep educating themselves about the realities of manufacturing increasingly intricate boards. Last month’s column highlighted design considerations for the strip-etch-strip process and how manufacturers approach that phase of production. Now that we have a functioning board, we must protect the PCB from environmental hazards and document the circuit components. This article will detail the solder mask and legend process and offer best practices for designers to ensure a high-quality result.
