Current IssueThe Hole Truth: Via Integrity in an HDI World
From the drilled hole to registration across multiple sequential lamination cycles, to the quality of your copper plating, via reliability in an HDI world is becoming an ever-greater challenge. This month we look at “The Hole Truth,” from creating the “perfect” via to how you can assure via quality and reliability, the first time, every time.
In Pursuit of Perfection: Defect Reduction
For bare PCB board fabrication, defect reduction is a critical aspect of a company's bottom line profitability. In this issue, we examine how imaging, etching, and plating processes can provide information and insight into reducing defects and increasing yields.
Voices of the Industry
We take the pulse of the PCB industry by sharing insights from leading fabricators and suppliers in this month's issue. We've gathered their thoughts on the new U.S. administration, spending, the war in Ukraine, and their most pressing needs. It’s an eye-opening and enlightening look behind the curtain.

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.”

Digital Twin Concept in Copper Electroplating Process Performance
07/11/2025 | Aga Franczak, Robrecht Belis, Elsyca N.V.PCB manufacturing involves transforming a design into a physical board while meeting specific requirements. Understanding these design specifications is crucial, as they directly impact the PCB's fabrication process, performance, and yield rate. One key design specification is copper thieving—the addition of “dummy” pads across the surface that are plated along with the features designed on the outer layers. The purpose of the process is to provide a uniform distribution of copper across the outer layers to make the plating current density and plating in the holes more uniform.
Trump Copper Tariffs Spark Concern
07/10/2025 | I-Connect007 Editorial TeamPresident Donald Trump stated on July 8 that he plans to impose a 50% tariff on copper imports, sparking concern in a global industry whose output is critical to electric vehicles, military hardware, semiconductors, and a wide range of consumer goods. According to Yahoo Finance, copper futures climbed over 2% following tariff confirmation.
Happy’s Tech Talk #40: Factors in PTH Reliability—Hole Voids
07/09/2025 | Happy Holden -- Column: Happy’s Tech TalkWhen we consider via reliability, the major contributing factors are typically processing deviations. These can be subtle and not always visible. One particularly insightful column was by Mike Carano, “Causes of Plating Voids, Pre-electroless Copper,” where he outlined some of the possible causes of hole defects for both plated through-hole (PTH) and blind vias.
Trouble in Your Tank: Can You Drill the Perfect Hole?
07/07/2025 | Michael Carano -- Column: Trouble in Your TankIn the movie “Friday Night Lights,” the head football coach (played by Billy Bob Thornton) addresses his high school football team on a hot day in August in West Texas. He asks his players one question: “Can you be perfect?” That is an interesting question, in football and the printed circuit board fabrication world, where being perfect is somewhat elusive. When it comes to mechanical drilling and via formation, can you drill the perfect hole time after time?
