Beyond the Rulebook
What happens when the rule book is no longer useful, or worse, was never written in the first place? In today’s fast-moving electronics landscape, we’re increasingly asked to design and build what has no precedent, no proven path, and no tidy checklist to follow. This is where “Design for Invention” begins.
March Madness
From the growing role of AI in design tools to the challenge of managing cumulative tolerances, these articles in this issue examine the technical details, design choices, and manufacturing considerations that determine whether a board works as intended.
Looking Forward to APEX EXPO 2026
I-Connect007 Magazine previews APEX EXPO 2026, covering everything from the show floor to the technical conference. For PCB designers, we move past the dreaded auto-router and spotlight AI design tools that actually matter.

Beyond Design: Demystifying Common‑Mode Radiation
02/24/2026 | Barry Olney -- Column: Beyond DesignCommon-mode radiation is a major contributor to unwanted electromagnetic interference (EMI). It arises when equal-phase currents flow on conductors without an opposing return current to cancel their fields. The resulting imbalance causes those conductors, especially attached cables, to behave as unintended antennas. Grasping how common-mode radiation is generated, the problems it creates, and the methods available to control it is essential for designing reliable electronic systems that meet regulatory requirements.
Beyond Design: Micro-ohm Power Delivery Network for AI-driven GPUs
11/18/2025 | Barry Olney -- Column: Beyond DesignThe evolution of modern processors, marked by faster edge transitions, reduced output impedance, and increasingly complex bus architectures, has significantly augmented the demands on PCB infrastructure. These challenges are compounded by AI-driven graphics processing units (GPUs), which require exceptionally high-power delivery at ultra-low operating voltages, placing greater stress on power integrity and layout design.
The Shaughnessy Report: Zee Plane! Zee Plane!
11/11/2025 | Andy Shaughnessy -- Column: The Shaughnessy ReportPlanes aren’t magic, but they are big time-savers. Without planes, designers would have to create thousands of traces to accomplish the same objectives. You can imagine the first time a designer thought about using a sheet of copper, asking, “Hey, why am I killing myself laying out all these traces? Can’t I just use this sheet of copper instead?”
November 2025 Design007 Magazine: Proper Plane Design
11/10/2025 | I-Connect007 Editorial TeamWithout planes, designers would have to create thousands of traces to accomplish the same objectives. Power planes provide low impedance and stable power to every component on the board, much like a large power bus. Ground planes stabilize reference voltage, improve thermal performance, and help preclude EMI issues. Power and ground plane design is often a battle of tradeoffs.
Everyone’s Talking About Power
11/06/2025 | Heidi Barnes, Keysight TechnologiesDelivering power to a digital load is an AC function, not DC. That simple statement may be obvious, but the implications of how electricity travels to an electronic load are complicated. Dynamic loads with rapidly changing currents create electric and magnetic fields that adhere to Maxwell’s equations. Ground can be misleading and is probably better used for describing where one grows potatoes and carrots. Electrical currents have “return paths,” and the energy is traveling in the fields between the power rail and the return path.
