Signal Integrity & Metallization
Signal integrity and additive manufacturing, particularly metallization, are hot topics in PCB design and fabrication. PCB layouts are carefully engineered to achieve specific electrical and power performance targets.
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.

Zhen Ding Highlights AI PCBs, IC Substrates at TPCA 2025
October 22, 2025 | Zhen DingEstimated reading time: 1 minute
The annual PCB industry event, TPCA Show 2025, kicked off on October 22 at the Nangang Exhibition Center. Zhen Ding Tech Group showcased a full range of high-end PCBs and IC substrates under the theme of artificial intelligence (AI).
Zhen Ding Tech Group showcased a full range of high-end PCBs and IC substrates under the theme of artificial intelligence (AI). Chairman Charles Shen pointed out that over the past 20 years, IC substrates have grown 20 times larger, increased in layer count by more than fourfold, and seen connection points surge by 300 times — resulting in overall complexity rising over 24,000 times.
This evolution signifies that PCBs have transformed from mere connectors into core enablers of AI computing performance. Facing this AI- and high-performance computing-driven revolution, Zhen Ding has strengthened its “One ZDT” strategic layout, pioneering a new ecosystem of “Semiconductor + Advanced Packaging + PCB” to fuel future growth momentum.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week
05/15/2026 | Nolan Johnson, I-Connect007When you work in the news business, even in trade media, you can never really get that far away from it. We never want to miss something important. Chances are, even the books we take on our “vacations” end up having to do with the business. For example, my colleague Michelle Te recommended “Creativity, Inc., by Ed Catmull, a business skills study wrapped up in stories about Pixar, which I brought with me on a trip through the stunning U.S. Mountain West. Now, I’m back, and here are my recommendations for the week.

Rethinking Stackup, Materials, and Tolerances in Modern Designs
05/14/2026 | Kristin Moyer, Global Electronics AssociationThe simple rectangular rigid PCB is becoming increasingly infrequent. This reality necessitates designing with concepts well outside traditional rigid PCB methodologies. For example, the designer of wearable electronics may need to implement conductive fibers integrated into the textile material. Heads-up displays, like those in VR/AR headsets and glasses, require transparent circuitry etched into the display glass. The process of designing without a rule book usually starts with something other than the traditional board design process.
Separating Fact from Fear on the FCC ‘China Lab Ban’
05/14/2026 | Jan Pedersen, NCAB GroupRecent news headlines have suggested that the U.S. Federal Communications Commission (FCC) has “banned all testing laboratories in China and Hong Kong.” Understandably, this has created concerns around PCB testing, material approvals, UL listings, and the continued use of established test laboratories in Asia. The good news is that for most PCB, PCB material, and PCBA testing, nothing has changed. Let’s separate fact from fear.
