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

07/23/2026 | Marcy LaRont, I-Connect007
In this week’s top five must-reads, I chose articles that go from big business questions (to diversify or not), to important technical issues such as DFM errors made in creating HDI designs using ELIC and design for test, to a discussion around some of the power and thermal considerations in advanced packaging, and the fact that they are now, firmly, performance enablers, not after-the-fact elements to be managed in fabrication.

Fresh PCB Concepts: IPC-6012 Class 3 and High-reliability PCB Manufacturing

07/23/2026 | Team NCAB -- Column: Fresh PCB Concepts
IPC-6012 Class 3 is widely recognized as the benchmark for high-reliability manufacturing. Compared to Class 2, it establishes tighter requirements for plated holes, annular rings, copper wrap, conductor integrity, and inspection criteria. Those requirements reduce manufacturing defects and improve overall product quality. A common misconception is that a Class 3 PCB is inherently reliable. It isn't. IPC-6012 is fundamentally a workmanship and performance specification that defines manufacturing acceptability after the design is complete.

Power and Thermal Constraints in AI Accelerator Packages

07/17/2026 | Chetan Arvind Patil, Marvell Technology
For more than five decades, semiconductor progress was driven primarily by transistor scaling. Moore's Law provided a predictable path for increasing transistor density, while process technology advancements consistently improved performance, power efficiency, and manufacturing cost. During this period, package development evolved alongside silicon, supporting higher pin counts, faster interfaces, and improved thermal performance, but it rarely dictated overall system capability.

Below the Surface: Ceramic vs PCB—When ‘Good Enough’ Becomes System Failure

07/15/2026 | Chandra Gupta -- Column: Below the Surface
Let’s start with the question engineers are increasingly asking themselves: “When should I use ceramic instead of FR-4?” It’s a fair question. FR-4 has been the backbone of electronics for decades. It’s affordable, widely available, and for many applications, it works just fine. Until it doesn’t.

Fresh PCB Concepts: Engineering Copper Coin and Copper Pedestal Technology With IPC Design Interpretation

06/25/2026 | Team NCAB -- Column: Fresh PCB Concepts
Copper coin and copper pedestal technologies have become increasingly important in modern PCB design as thermal demands rise in power electronics, automotive systems, RF applications, aerospace electronics, and high-density computing environments. As component power density increases and board sizes shrink, traditional thermal management techniques often become insufficient to maintain acceptable operating temperatures and long-term reliability.
