The companion guide to On the Line With…American Standard Circuits: Ultra High Density Interconnect (UHDI) explores how UHDI is reshaping PCB design and manufacturing. As trace widths shrink from 25 microns toward 5 microns, UHDI enables finer geometries, tighter impedance control, improved RF performance, and reduced layer counts.
In this resource, the authors outline the key differences between HDI and UHDI, covering advanced via structures, copper-filled microvias, material innovations, and solder mask considerations. The guide explains how UHDI gives designers greater routing freedom while requiring stricter process discipline and earlier collaboration with fabricators. It goes on to explain why UHDI is ideal for RF, high-speed, aerospace, and miniaturized applications, delivering meaningful improvements in size, weight, power, reliability, and overall electronic performance.

From Backbone to Breakthroughs: I-Connect007 Wraps PCB Materials Series with Focus on Innovation
04/30/2026 | I-Connect007I-Connect007 wraps up its six-part podcast series, PCB Materials: The Backbone and Future of Electronics, with Episode 6 and a discussion focusing on innovation. In Episode 6, Marcy LaRont speaks with Isola CTO Kirk Thompson about a critical turning point for the PCB industry as innovation accelerates. As data rates climb and demands from AI infrastructure, power density, flexible electronics, photonics, and chiplet integration intensify, traditional material assumptions are no longer sufficient.
ASC’s John Johnson Bullish on the U.S. and High-tech PCBs
04/28/2026 | Marcy LaRont, I-Connect007It was a good couple of days at the SMTA UHDI Symposium in Avondale, Arizona, in early April, where John Johnson, head of technology at American Standard Circuits (ASC) and resident PCB expert on UHDI in the real-world of manufacturing, was a presenter. As the symposium ended, I visited with John, who reflected on what he considered most important and what had made the greatest impression on him.
SMTA Ultra HDI Symposium, Day 2: Fragile Supply Chains, Fierce Innovation
04/14/2026 | Marcy LaRont, I-Connect007The Arizona weather yielded another beautiful day as we gathered for the second day of SMTA’s annual UHDI symposium. After the first full day discussing the role of AI in business and the how-tos of implementation, Avondale Mayor Mike Pineda kicked off day two, proud to showcase his city and to declare its important place in the continued development of the West Valley, an increasingly important area for tech and manufacturing.
SMTA Ultra HDI Symposium, Day 1: AI at the Core or Out of the Game
04/13/2026 | Marcy LaRont, I-Connect007It was a beautiful 81°F morning in Arizona last Wednesday as I headed to the third annual SMTA Ultra HDI Symposium, focused on AI and ultra high density interconnect technology. Strategically held as part of Arizona’s Tech Week, this year’s conference took place in Avondale in Phoenix's West Valley. The event moved from the cozy offices of the Peoria Sports Complex (which paid homage to baseball’s spring training world) to the larger Avondale Conference Center, highlighting the importance of this area for electronics manufacturing investment.
Sustainability Takes Center Stage in ‘On the Line With… Isola’ Podcast, Episode 3
