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.

Listen Up! The Intricacies of PCB Drilling Detailed in New Podcast Episode
April 25, 2024 | I-Connect007Estimated reading time: 1 minute
In episode 5 of the podcast series, On the Line With: Designing for Reality, Nolan Johnson and Matt Stevenson continue down the manufacturing process, this time focusing on the post-lamination drilling process for PCBs. Matt and Nolan delve into the intricacies of the PCB drilling process, highlighting the importance of hole quality, drill parameters, and design optimization to ensure smooth manufacturing. The conversation covers topics such as drill bit sizes, aspect ratios, vias, challenges in drilling, and ways to enhance efficiency in the drilling department. Listeners will also learn about the critical relationship between design choices and manufacturing capabilities, as well as subsequent steps of metalizing the drilled holes through an electrolysis process.
This series is all about the specifics that can affect your circuit board during the manufacturing process and includes tips and tricks for optimizing design, fabrication, yields, and cost.

Driving Innovation: Size Matters—Navigating the Challenges of XXL PCB Production
03/02/2026 | Kurt Palmer -- Column: Driving InnovationIn high-end electronics, complexity is often measured in microns. However, when those microns are spread across a massive surface area, the engineering challenge fundamentally changes. Imagine two panels: Both are highly complex, featuring 4-stage build-ups, 2-mil line and space patterns, 2-mil microvias, and through-holes with a demanding 1:30 aspect ratio.

Connect the Dots: Designing for the Reality of UHDI PCBs—Drilling
11/04/2025 | Matt Stevenson -- Column: Connect the DotsUltra high density interconnect (UHDI) PCBs are changing the game in designing for the reality of manufacturing. With both consumer and industrial electronic devices becoming more advanced, the demand for UHDI PCBs will grow. That means we’re all likely to be designing more UHDI boards. UHDI advanced miniaturization technology challenges designers with regard to both board thickness and footprint. Designers will face more variables in every aspect of design creation. This is certainly the case with drilling.
Driving Innovation: Mastering Panel Warpage
09/23/2025 | Simon Khesin -- Column: Driving InnovationDuring the complex and multi-step process of PCB fabrication, a panel's flatness is constantly at risk. A host of factors can introduce warpage, bending, and unevenness, presenting a fundamental challenge to achieving high-precision results. This deformation (sometimes referred to as “bow and twist”), even on a microscopic scale, can lead to critical defects during subsequent stages, such as component surface mounting (e.g., tombstoning, solder opens) and the PCB's long-term functional reliability.
