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.
Looking Forward to APEX EXPO 2026
I-Connect007 Magazine previews APEX EXPO 2026, covering everything from the show floor to the technical conference. For PCB designers, we move past the dreaded auto-router and spotlight AI design tools that actually matter.

MacDermid Alpha to Exhibit, Present at TPCA and IMPACT
December 14, 2021 | MacDermid Alpha Electronics SolutionsEstimated reading time: 1 minute
MacDermid Alpha Electronics Solutions, a global supplier of integrated solutions from our Circuitry, Assembly and Semiconductor divisions that provides unmatched capabilities in electronics design and manufacturing, will be exhibiting at the Taiwan Printed Circuit Association (TPCA) exhibition and will present at the IMPACT Conference, co-located with TPCA at the Nangang Exhibition Center Taipei, Taiwan, December 21-23, 2021.
Maddux Sy, Applications Manager for the Metallization group, will be presenting “ RDL and Pillar Fabrication from a Versatile Copper Plating Process“. The paper discusses the challenges fabricators face not only in meeting the copper plating performance requirements but also in reducing manufacturing process costs.
Interested participants can stop by booth K606 in Hall 1 to talk to our industry experts about the latest offerings from MacDermid Alpha. Featured in the booth will be the MacDermid Enthone brand of product offerings that enable the most complex printed circuit board and IC Substrate designs. Highlighted will be the entire Systek family of high performance build-up processes for IC Substrate RDL that provide multiple process flows for differet materials, Affinity 2.0, the new Affinity Gold 3.0 and the soon to be released Affinity Select, the OSP compatible selective ENIG process. Also featured will be the full portfolio of MacuSpec acid copper products that meet all applications, from ultra-aspect ratio conformal plating down to filling the smallest blind microvias.

Driving Innovation: Selecting the Right Laser Source
04/28/2026 | Simon Khesin -- Column: Driving InnovationWhen I first joined Schmoll Maschinen, I brought experience from almost every PCB process, except for laser. As I immersed myself in laser processing, I realized why it can seem so daunting to a newcomer. The complexity arises from three intersecting factors: A vast variety of laser sources: CO2, UV-nano, green-pico, UV-pico, IR-pico, and others; a diverse range of applications: Drilling, cutting, ablation, and more; and an extensive list of materials: These have vastly different absorption rates. Choosing the right machine or laser source is rarely trivial. Even for experienced engineers, answering "Which source is best?" requires examining the business's specific goals.
Institute of Circuit Technology Spring Seminar 2026: A Bright Future in Europe
04/23/2026 | Pete Starkey, I-Connect007Through the leafy lanes and spring flowers of Warwickshire and back to Meridan, the traditional centre of England, and now officially part of the Metropolitan Borough of Solihull in the county of the West Midlands, I attended the Annual General Meeting and Spring Seminar of the Institute of Circuit Technology (ICT) on April 14. Out of the AGM came notable changes in leadership at the top of the Institute: the retirement of Mat Beadel as chair and Emma Hudson as technical director. Effective May 1, Steve Driver is the new chair, and Alun Morgan is the new technical director.
ACCM Unveils Negative and Near-zero CTE Materials for Large-Format AI Chips
04/21/2026 | Advanced Chip and Circuit MaterialsAdvanced Chip and Circuit Materials, Inc. (ACCM) has launched two new materials: Celeritas HM50, with a negative coefficient of thermal expansion (CTE) of -8 ppm/°C to offset the positive CTE and expansion of copper with temperature on circuit boards, and Celeritas HM001, with near-zero CTE and the low-loss performance needed for high-speed signal layers to 224 Gb/s and faster in artificial intelligence (AI) circuits.
Fresh PCB Concepts: Designing PCBs for Harsh Environments—Reliability Is Engineered Upstream
04/23/2026 | Team NCAB -- Column: Fresh PCB ConceptsWhen engineers hear the phrase “harsh environment,” they usually think of the extreme temperature swings, vibration and shock, pressure changes, or radiation in aerospace. However, aerospace is not the only harsh environment where electronic assemblies must survive. Automotive power electronics, downhole oil and gas tools, marine controls, rail systems, defense platforms, and industrial automation equipment all expose PCBs to environments that are equally unforgiving. The stress mechanisms may differ, but the physics does not.
