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.

HSIO Circuit Technologies Acquires former HEI Circuit Fabrication Operation in Tempe, AZ
January 11, 2016 | HSIO Circuit TechnologiesEstimated reading time: 1 minute
HSIO Technologies, LLC headquartered in Maple Grove MN announces that on December 14, 2015 a wholly owned subsidiary HSIO Circuit Technologies, LLC acquired the former HEI Circuit Fabrication operation Cochlear Tempe, LLC in Tempe AZ. The Tempe operation was considered a leading domestic supplier of Rigid Flex, Flex Circuit and Rigid PCB substrate products and was acquired by Cochlear LTD of Sydney Australia early 2015 as part of bankruptcy proceedings of the parent HEI, Inc. of Victoria MN. The operation will continue production as an ongoing concern and introduce new enhanced and expanded capability in 2016 under the HSIO Circuit Technologies, LLC operating unit. The goal of the operation is to provide industry leading domestic supply of very fine line and space circuit fabrication focused on small form factor high performance Flex Circuit, Rigid Flex, Rigid PCB, and Semiconductor Package Substrate applications. In addition to conventional circuit applications, the operation will implement production of HSIO’s next generation Liquid Crystal Polymer (LCP) high performance high density circuit fabrication capability which enables extreme impedance tuning with high aspect ratio circuits and full metal copper vias capable of 12 micron geometries in an implantable material set.
This acquisition complements the 2012 asset acquisition of R&D Interconnect Solutions to provide the industry leading combination of high performance Printed Circuit, Semiconductor Test Socket, Wafer Probe and Connector products available with over 60 US and International patents issued, granted, licensed and pending with tuned performance beyond 40 GHz.

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.
Advanced Packaging for AI: Reliability Starts at the Cu/Cu/Cu Microvia Junction
04/20/2026 | Kuldip Johal, MKS' AtotechThe rapid growth of AI computing, from training clusters to inference at scale, is reshaping demand across the entire electronics supply chain. Advances in technology requirements, such as higher bandwidth, lower latency, and greater compute density, are driving the development of advanced packaging technologies and transforming the PCB industry across design, manufacturing, testing, and even architecture.
Volatile Metals Market Creates PCB Pricing Headache
04/20/2026 | Nolan Johnson, I-Connect007Market volatility for precious metals is very real. Financial organizations have reported elevated volatility, with record highs and steep corrections; in 2025 alone, gold has increased by over 60%, silver over 120%, and copper over 35%. Each is a critical raw material used in electronics manufacturing, where pricing is already fraught for business owners and their customers due to tariff uncertainty and a critical supply chain that resides mostly in China. The volatility of precious metals markets adds yet another layer of complexity for manufacturers, pushing up raw material costs.
