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.

Infinitum Acquires Circuit Connect, Inc.
April 20, 2023 | Business WireEstimated reading time: 2 minutes
Infinitum, creator of the sustainable, breakthrough air core motor, today announced the acquisition of Circuit Connect, Inc. a printed circuit board (PCB) fabricator based in Nashua, New Hampshire that has consistently served the OEM and electronic manufacturing industry for 30 years.
The acquisition of Circuit Connect, Inc. supports Infinitum’s efforts to become more vertical and immediately allows for a substantially higher production capacity of PCB stators. The acquisition also provides a framework for continuous volume growth, which is critical to meeting the high demand for Infinitum’s innovative electric motor technology.
Infinitum’s unique air core motor motors replace heavy iron found in traditional electric motors with a lightweight, printed circuit board (PCB) stator that is 10x more reliable. Infinitum motors are 50 percent smaller and lighter, use 66 percent less copper and consume 10 percent less energy than standard iron core stator motors. The motor’s modular design allows the housing, rotors, and stators to be reused multiple times, giving parts a second and third life to serve future generations.
Circuit Connect, Inc has supplied Infinitum with PCB stators for more than 5 years, and has been closely involved in developing the manufacturing process and quality product that is at the heart of Infinitum’s award winning motors. The company has 21 employees who will join the Infinitum family, while continuing to service existing customers via the operation from Nashua, New Hampshire.
“Our PCB stator is the heart of our sustainable electric motors and what allows us to deliver the efficiency and energy savings that is so important to our customers and the planet,” said Ben Schuler, founder and CEO of Infinitum. “Circuit Connect has worked side by side with us advancing and improving how PCB stators are made. Their acquisition will help us ensure consistent delivery of quality stator components as we execute on our hypergrowth phase and scale up manufacturing to meet demand for our motors that can power the world with less energy and waste.”
“As a leader in PCB fabrication in the US for more than three decades, Circuit Connect’s dedication to customer success aligns well with Infinitum’s mission to build motors with reliability and extended life,” said Rick Clutz, founder, Circuit Connect. “We look forward to continuing to serve our customers and are excited about the next chapter as we ramp up production to help create motors that can have such a lasting and positive impact on the environment.”

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.
