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.

Powering the Future: Performance Is Won in Assembly

08/05/2026 | Brian Buyea -- Column: Powering the Future
There’s a moment in every design cycle when the conversation shifts from the elements of a substrate—material selection, thermal conductivity, circuit density, layout, and performance on paper—to how it performs in assembly. No matter how good your substrate is, if the assembly isn’t right, none of it matters. Engineers are coming to terms with the fact that performance is more than the circuit. It’s now about the system, and that’s where assembly stops being an afterthought and becomes the whole game.

Learning With Leo: Where Reliability Actually Hides

08/05/2026 | Leo Lambert -- Column: Learning With Leo
In my many years of training, it’s funny to see what still surprises people. For example, they’re surprised that by the time the solder melts, most of what decides whether that joint survives has already happened before the iron and even before inspection. In fact, it’s even earlier than that. In my column last month, I argued that most soldering problems are really problems of interpretation, which leads to the materials themselves, and where reliability is won or lost. So, let’s talk about what we’re actually soldering today.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

07/31/2026 | Michelle Te, I-Connect007
When I first came to the electronics industry, I was coming from the outside. Over time, I learned that this is not an industry that can be understood from just one angle. What happens in design affects manufacturing. Material choices affect reliability. Supply chain decisions influence business strategy, and advances in technology create new challenges and opportunities throughout the entire ecosystem. That complexity is one of the things I appreciate most about covering this industry. Each week, I’m reminded that there is always another layer to explore.

Henniker Plasma Targets Throughput and Process Stability with Stratus Manufacturing Solution

07/20/2026 | Henniker Plasma
Manufacturers scaling a bonding, coating or printing process to full production rarely struggle with the science of surface treatment; they struggle with holding it steady, line after line, shift after shift.
