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.

EMC, Arlon Industry Leading PWB Laminates at DesignCon 2024
January 29, 2024 | EMCEstimated reading time: 1 minute
At the DesignCon 2024 Expo, drop by EMC/ Arlon booth #1260 and learn from the experts with the results from a wide range of performance testing that some of our key OEM customers in almost all market segments of technology, have completed. Our EM-892K products continue to gain wide acceptance within the AI Server and 800G switch market spaces. We are on track to also introduce our EM-896K3 which will offer even higher speed/low loss solutions including for the 224 Gbps PAM4 product requirements.
EMC has also added another high-speed/low loss solution for Automotive Sector laminate needs. We have introduced the EM-A56 for next generation ADAS implementations designed with 3.2 Dk/0.004 Df along with its enhanced very low Z axis CTE of 1.8% with material samples currently available for testing. Additionally, we are introducing EM-A30 with a low Z-axis CTE of 1.7% that will also have a UL Comparative Tracking Index of ‘1’, that will be ideal for very high voltage electronics for automotive and industrial applications.
For Automotive and 5G/Antenna applications, we are introducing EM-A70/EM-A70K which is a lower cost non-PTFE based system that provides more cost-effective solutions for antenna applications.
For dedicated mission critical PWB’s for military, aerospace, down hole oil and gas drilling, burn-in and automatic test equipment, Arlon has introduced 86HP as the revolutionary addition to Arlon’s best-in-class high performance polyimide laminate systems engineered to meet high temperature, electrical and mechanical performance not found with any other polyimide resin system. 86HP also meets IPC-4101 slash sheets 40 and 41.
86HP is designed for dense circuit configurations due to the Anti-CAF performance of over 1,000 hours at 85% RH/85⁰C/ 100V DC, low-Z-axis expansion of <1% between 50⁰C to 260⁰C for high layer count MLB’s, very high decomposition temperatures of 430⁰C, high thermal conductivity of 0.6 W/mK, low moisture uptake of 0.12% for sensitive climate applications and is ideal for sequential lamination designs requiring up to seven additional lamination steps.

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.
Powering the Future: Why Thermal Management Defines the Future of Electronics
04/15/2026 | Brian Buyea -- Column: Powering the FutureEvery leap forward in electronics comes with a familiar consequence: heat. Whether it’s a power module driving an electric vehicle, a laser diode used in surgery, or a 5G amplifier operating in orbit, higher performance inevitably means higher temperatures. While engineers celebrate breakthroughs in speed, density, and power, none of those specifications matter if the system can’t keep cool long enough to perform reliably.

SMT Perspectives & Prospects: Artificial Intelligence, Part 7—Data Module 2
04/08/2026 | Dr. Jennie Hwang -- Column: SMT Perspectives and ProspectsWhen I last wrote about data, I focused on data quality and size, data infrastructure, the boundaries of data training, data preparation, and the general challenges and concerns of data. This month, I will focus on alternative approaches, data governance, retrieval-augmented generation (RAG), and agentic RAG.
