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.

Aismalibar to Exhibit at APEC 2023
March 7, 2023 | AismalibarEstimated reading time: 1 minute
Aismalibar will be attending the APEC, the leading conference for practicing power electronics professionals, in Orlando, Florida from March 19-23. Aismalibar will be presenting new cooling technologies for power electronics, specifically Thermal Interface Materials (TIMs) and Insulated Mental Substrates (IMS).
Aismalibar Thermal Interface Materials have been designed to improve dielectric isolation and fast thermal transmission in battery assemblies, taking into consideration cost reduction, lifetime performance, safety, and reliability.
Our Thermal Interface Materials are divided into two main areas, differentiated based on whether they need dielectric capacity. Dielectric requirement is determined by the electronic device, its operating voltage, and the applicable regulations regarding ground insulation. Additionally, Aismalibar has developed a series of applicable surfaces on the TIMs, differentiated by whether they need to be self-adhesive. Both surfaces serve, in turn, to reduce the air cavities that exist between the surfaces of the TIMs and the heatsinks or electronic components.
COPPERFILLER and BOND SHEET CURED offer a high-performance alternative solution to current thermal pastes or pads. The new COBRITHERM ALP is made from an aluminum base that is dielectrically insulated, designed to build structures, covers, partitions or radiators, among other solutions. It is completely insulated and guarantees excellent contact between the battery and dissipation elements.
IMS METAL CLAD Is a thick aluminum-based substrate, cladded in ED copper foil, designed for an effective thermal dissipation and high electrical insulation. Our proprietary formulated polymer-ceramic ensures high thermal conductivity, dielectric strength, and thermal endurance. AISMALIBAR’s Insulated Metal Substrates allow processing by standard PCBs procedures, integrating heat dissipation with no need for extra components and SMD assembly process.
Visit us at booth 136 to learn more about our products. We look forward to speaking with you.

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.
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.
