The Signal Integrity Issue: Design007 Magazine September 2025
September 9, 2025 | I-Connect007 Editorial TeamEstimated reading time: 1 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.

Target Condition: When Design Outpaces Manufacturing
04/23/2026 | Kelly Dack -- Column: Target ConditionMost PCB designers already understand why design for manufacturing (DFM) matters. If a product can’t be built reliably, repeatedly, and at a price anyone will actually pay, it’s dead on arrival. You may have the most elegant schematic and layout ever drawn in a CAD tool, but if the PCB suppliers can’t make it, or the EMS sources refuse to quote it, you may well be considered more of a Nutty Professor or well-meaning inventor than a PCB designer.
Single Pair Ethernet (SPE): A Valuable Option for Modern Designs
04/20/2026 | Marcy LaRont, I-Connect007When it comes to designing PCBs and full systems for increasingly complex electronics hardware, who doesn’t want to reduce complexity and cost? Single-Pair Ethernet (SPE) has emerged as a solution and is gaining rapid attention across industrial electronics and PCB design because it enables Ethernet communication over a single twisted pair, replacing the traditional two- or four-pair cabling used in standard Ethernet networks. This seemingly simple shift has significant implications for designers: smaller connectors, reduced cable weight, longer reach, and the ability to carry both data and power over a single pair.
