Below the Surface: Why Thermal Failure Is Still the No. 1 Killer in Power Electronics

08/13/2026 | Chandra Gupta -- Column: Below the Surface
Why do power electronics fail? There’s a range of answers, from overvoltage and mechanical stress to poor assembly and environmental exposure. If you ask your favorite AI search engine for an answer, you’ll get a pretty simple response: excessive temperature leads to component degradation, material breakdown, and eventual failure. In a sense, that’s true, but it’s oversimplified and incomplete. The real issue is thermal management failure at the system level. Heat is still the number one killer, and most of the time, you don’t even realize it’s there.

Ventec’s Glass-Free Revolution: Smarter Material Data for Next-Gen PCB Designs

Advanced Electronic Packaging: The Industry's New Innovation Engine

08/13/2026 | Marcy LaRont, I-Connect007
Over the past several years, advanced packaging has moved from the back end of semiconductor manufacturing to becoming one of the electronics industry's most strategic technologies in the ecosystem. At many IEEE conferences, discussions that once centered almost exclusively on transistor scaling now devote equal attention to chiplets, heterogeneous integration, co-design, advanced substrates, thermal management, and system-level packaging.

A Practical Approach to Material Selection for High Power PCBs

08/13/2026 | Drew Delaney, Isola Group
With AI server architectures demanding high-power converter solutions to improve power efficiency and affordability, PCB design can challenge engineers who treat material selection as a single-variable problem. Pick a laminate for thermal conductivity, and you may experience a CTE mismatch that cracks vias after 50 thermal cycles. Optimize for dielectric loss, and you might sacrifice the isolation margin your certification depends on. High-power boards require consideration of multiple variables, including electrical, thermal, mechanical, reliability, and manufacturability, which cannot be optimized alone.

Understanding Design for Display Electronics

08/12/2026 | Marcy LaRont, I-Connect007 Magazine
For Kristin Moyer, designing display electronics is all about scale. As displays shrink in size and grow in resolution, every engineering decision becomes more demanding. In this interview, the Global Electronics Association design instructor explains the strengths and limitations of today’s dominant display technologies—LCD and LED—as well as the emerging role of AR/VR displays. Kristin also explores the PCB design, manufacturability, and reliability challenges that accompany each.
