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.

Call-for-Participation Webinar Board-Level Optical Interconnect Performance in Immersion-Cooled Environments
April 24, 2023 | iNEMIEstimated reading time: 1 minute
Join us April 25 to learn about iNEMI’s new Board-Level Optical Interconnect Performance in Immersion-Cooled Environments project. Immersion cooling is gaining traction as a means of disruptive thermal management in high-performance computing and data centers; however, there is insufficient understanding of how optical interconnect components will perform in immersion-cooled environments. This issue affects OEMs and companies involved with photonics integration, mid-board optics and co-packaged optics.
The objectives of this new project are to:
Investigate and evaluate different on-board optical components and interconnect solutions in different immersion-cooled environments including single phase and dual phase.
Understand how design factors of interconnect components affect performance in an immersion environment.
Registration
These sessions are open to industry; advance registration is required, visit iNEMI's website.

Knocking Down the Bone Pile: Precision Milling of Underfilled SMT Components
05/13/2026 | Nash Bell -- Column: Knocking Down the Bone PileUnderfill is a polymeric material used to fill the gap between a printed circuit board and the underside of surface-mount area-array packages such as BGA, QFP, and QFN devices, thereby surrounding and protecting the solder interconnections. This material increases the component's reliability when subjected to mechanical impacts and shocks by distributing forces.
Connect the Dots: Designing for the Future of Manufacturing Reality—Surface Finish
05/07/2026 | Matt Stevenson -- Column: Connect the DotsWhen designing the complex boards that many electronic devices require to operate, designers should consider manufacturability at every step. This is my last article focused on designing for the always-evolving manufacturing reality. Choosing the right surface finish has always been important. If you are creating intricate designs with a wide variety of components, like for an ultra-high density interconnect (UHDI) board, surface finish is a critical last step.
Strong AI Demand vs. Weak Consumer Segment Creates Pricing Divergence Among MLCC Suppliers
04/28/2026 | TrendForceTrendForce’s latest research shows that the MLCC market in 2Q26 is showing a clear split between robust AI-driven demand and soft consumer demand.
Cleaning Is Critical
04/28/2026 | Nolan Johnson, SMT007 MagazineMike Bixenman, president of Magnalytix, and his colleagues Vladimir Sitko, founder of PBT Works, and Adam Klett, PhD, director of science at KYZEN, discussed how cleaning can affect reliability, in a Professional Development Course at APEX EXPO 2026. We spoke to Mike after the session to better understand the context for the current activity in cleaning technology.
