Aurora Circuits Launches Collaborative Webinar Series With Focus on Ultra-Heavy Copper PCBs
July 31, 2020 | Aurora CircuitsEstimated reading time: 1 minute
Dr. Christopher Kalmus, president of Aurora Circuits, announced recently that Aurora Circuits is launching a new Collaborative Webinar Series with the first one being on ultra-heavy copper PCBs. The first webinar is live on August 12 from 12:00–2:45 p.m. CT.
Aurora Circuits, located in Aurora, Illinois, is one of the PCB industry’s leaders when it comes to producing heavy copper PCBs with capabilities to produce boards with over 20 ounces of copper. Ultra-heavy copper is the company's term for boards with anything over 15 ounces of copper.
The ultra-heavy copper webinar will cover: The advantages and uses for ultra-heavy copper in the PCB industry, and advancements in this technology; key uses cases and exactly how Aurora Circuits collaborates with designers and engineers across the world on this technology.
Presenters will be:
- Dr. Chris Kalmus: President, Aurora Circuits
- Thad Bartosz: Director of Business Development, Aurora Circuits
- John Holmquest: Director of Engineering, Aurora Circuits
- Brian Zirlin: Director of Sales and Marketing, Aurora Circuits
- And special guest: Steve Taylor of Thermal Substrate Solutions.
When making this announcement, Dr. Kalmus said, “Heavy copper is a technology whose time has come. With the onset of Electronic and Autonomous vehicles and the advances in all technologies especially LED lighting, we have seen a huge uptick in the demand for heavy copper PCBs. We have designers and engineers calling us every day looking for more information about heavy copper technology which is why as a service to our industry we decided to produce this webinar. We hope that everyone who is interested in heavy copper, especially our ultra-heavy copper, will join us on August 12.

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

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?
