Road to Reliability: The Foundational Technologies of Materials in EV Reliability

06/04/2026 | Stanton Rak, SF Rak Company
EV reliability is often discussed at the vehicle or system level, but many of the most persistent failures begin at the materials level. Semiconductor devices, ceramic substrates, die attach materials, wire bonds, clips, thermal interface materials, laminates, coatings, seals, and coolants define the electrical, thermal, and mechanical limits of the hardware. Once EV architectures move toward higher voltages, switching speeds, and power density, and longer service life, those materials are pushed harder, and small weaknesses can turn into large field problems

Beyond Design: How Signals Survive the Hostile PCB Environment

06/03/2026 | Barry Olney -- Column: Beyond Design
Modern digital signals exhibit behavior more characteristic of RF waveforms than the slow logic transitions of the past. With fast rise times, a PCB is no longer a collection of copper traces, but a distributed electromagnetic system. Successful design isn’t about routing signals anymore; it’s about engineering transmission lines, preserving uninterrupted return‑current paths, and controlling the resonant structures that naturally form within the multilayer PCB.

Don’t Call It Ground, Call It Return

04/09/2026 | Kristin Moyer, Global Electronics Association
If you’ve studied electrical or computer engineering, or have just read an electronics schematic, circuit diagram, or other application notes, you've likely seen the term “Ground,” often abbreviated GND. This is used in school and during the teaching of electronics circuit analysis to indicate a reference or zero-voltage node for circuit analysis. It is also taught that there is no current in GND since the voltage is zero. These are assumptions made for the purpose of simplifying the introduction to circuit analysis.

Beyond Design: Demystifying Common‑Mode Radiation

02/24/2026 | Barry Olney -- Column: Beyond Design
Common-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.

Proper Plane Design Techniques

02/12/2026 | I-Connect007 Editorial Team
Continuing our discussion from the November issue of Design007 Magazine on proper plane design, Kris Moyer, an instructor for the Global Electronics Association, shares techniques he teaches his PCB design students to use. When it comes to plane design, there are several challenges with modern high-speed designs. Planes, or more specifically, mirror/return paths, are critical to proper controlled impedance transmission line design. Additionally, to mitigate high-speed switching “noise,” the use of planar capacitance is now necessary and critical.
