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.

Empowering the Future of Advanced Computing and Connectivity: DuPont Unveils Innovative Advanced Circuit Materials in Shanghai
March 24, 2025 | DuPontEstimated reading time: 2 minutes
DuPont will showcase how we are shaping the next generation of electronics at the International Electronic Circuits (Shanghai) Exhibition 2025. With a diverse portfolio of advanced circuit materials and solutions designed to push the limits of fine-line technology, signal integrity, and thermal management, DuPont will be exhibiting in Booth #8A31 at National Exhibition and Convention Center (NECC) from March 24-26.
"As artificial intelligence (AI), machine learning, and 5G technologies continue to advance, the demand for high-performance devices is propelling innovations in packaging substrates and high-end PCBs," said Yuan Yuan Zhou, Global Business Director, Advanced Circuit & Packaging, DuPont. "With our cutting-edge materials and integrated solutions, we are helping PCB manufacturers meet the increasing needs for miniaturization, integration, and performance, paving the way for the next generation of AI-driven substrates. Our advancement in interconnect materials plays a critical role in enabling AI infrastructure to optimize speed, efficiency, and reliability."
DuPont is leveraging decades of expertise in material science to address the evolving demands of the rapidly expanding IC substrate and high-end PCB market, fueled by the surge from AI servers and data centers, networking, autonomous vehicles, and 5G. The IC substrate offerings encompass a wide array of solutions, including dielectrics, metallization chemistries for electroless copper seed layer, redistribution layer, copper pillars, solder bumps, and dry film imaging photoresists. This comprehensive portfolio tackles critical challenges in performance, miniaturization, reliability, and cost efficiency.
At the show, DuPont experts will be available at the company's booth to share their in-depth knowledge on technological innovations and industry trends. Attendees can explore DuPont's comprehensive solutions for the PCB market, featuring the following product offerings:
DuPont™ Circuposit™ SAP8000 electroless copper is an innovative SAP metallization technology designed for AI server CPU or GPU chip applications. This ionic-based catalyst electroless copper process is optimized for advanced packaging. It meets the demands for low-roughness dielectrics as well as low dielectric constant (Dk) and low dissipation factor (Df) properties essential for fine-line and high-frequency designs.
DuPont™ Microfill™ SFP-II-M acid plating copper is a novel pattern plating solution specifically designed to optimize pattern distribution for large AI chips. It is engineered to deliver consistent pattern distribution across large unit sizes, making it ideal for high-performance computing applications.
DuPont™ Riston® DI1600 & DI1600M dry film photoresist is an advanced fine line direct imaging photoresist solution specifically designed for IC substrate applications. It boasts exceptional fine line adhesion and resolution, paired with high-yield performance.
DuPont™ Riston® DWB8100M dry film photoresist is a high-performance direct imaging solution tailored for fine copper pillar and thick copper mSAP applications. It offers excellent fine line and via resolution, with strong bottom adhesion to minimize underplating risks. It ensures stable yield performance while providing a straight dry film and copper trace profile with low trace voids, making it optimal for advanced IC substrate applications.
Testimonial

Nortech Systems Launches Power over Fiber Technology Platform for EMI-Sensitive Applications
04/08/2026 | Globe NewswireNortech Systems Incorporated, a leading provider of design and manufacturing solutions for complex electromedical devices and electromechanical systems, has announced the launch of its Power over Fiber technology platform.
Flexible Thinking: Designing Flex Circuits for Dynamic Reliability
04/09/2026 | Joe Fjelstad -- Column: Flexible ThinkingFlex circuits flex. No surprises there. However, they are also very commonly designed into products because they are thin and offer consistent thickness and dielectric properties, attributes highly prized by present-day product designers of personal electronics. This would include smartphones and, increasingly, wearable electronics for medical monitoring and even fashion.
Understanding Tolerances in Flexible Circuit Design
04/01/2026 | Chris Clark, Flexible Circuit TechnologiesThe challenge with cumulative tolerances is meeting the dimensional requirements for items dimensioned on a drawing or specification for a flexible or rigid-flex circuit. It is critical to understand the fabrication processes and how features are defined when creating your tolerance requirements.
Target Condition: An Exploration of Flooding PCB Layers
04/02/2026 | Kelly Dack -- Column: Target ConditionThe concept of flooding PCB layers with copper has been around for so long, you’d think we’d have it mastered. We haven’t. (Oh, and by “we,” I mean design engineers and the software tools we depend on.) Years ago, PCB artwork was created by hand using light tables, with tape applied to Mylar. Signals were slow, traces were relatively wide, and high-current paths were simply “beefed up” with wider copper. Signal integrity wasn’t yet a driving concern. Today, solid return paths are fundamental to robust design. We understand the importance of continuous reference planes for signal integrity and EMI control.
New, Greener Solutions for Etch: Novel Copper Extraction
03/30/2026 | Richard Nichols, GreenSource Engineering“Novel” is a typical marketing phrase that implies new and unique, but often “novel” actually means an established technology being applied to a new field or application. This, in turn, is often driven by newly relevant external motivation. GreenSource has been working on just such a solution: novel copper extraction, offering a better and greener alternative to traditional LLE control systems for cupric chloride etch.
