David Griesel, CEO of Sunrise Group, has been in the PCB industry for nearly 50 years. “I didn’t even have a desk when I started,” says David, who, as a fresh college graduate, got his start at Norplex, a company in Wisconsin that made plastic. “At that time, I had no idea what plastic was even about.” But it gave him an opportunity to learn the business from the ground up. He worked in customer service, followed by technical sales and marketing through several iterations of the company, including as Isola. I hope you’ll enjoy this interview with David as much as I did.

In recent years, there has been a notable shift in the electronics manufacturing supply chain landscape. However, the global supply chain for the domestic PCB industry has been steadily shifting since the 1980s, when the United States began offshoring PCB manufacturing to other countries. But because of the quality control issues, rising international tariffs, and unclear intellectual property protection involved in offshoring, reshoring has become a particularly hot topic.

In the world of PCB design, miniaturization can be achieved by using low dielectric constant (Dk) materials. Low Dk materials can allow for a reduction in thickness while maintaining a given trace width, leading to lower transmission loss and higher density circuitry.

I had the great pleasure of recently attending the National Institute of Standards and Technology’s (NIST) CHIPS R&D Chiplets Interfaces Technical Standards Workshop. The purpose was to bring together technical experts across industry and academia to deliberate one of the most pressing technological matters of 2024: chip packaging standards.

On May 11, 2023, Reps. Blake Moore (R-UT) and Anna Eshoo (D-CA) introduced the Protecting Circuit Boards and Substrates (PCB) Act to Congress. In October, I had the great pleasure of discussing the bipartisan Protecting Circuit Boards and Substrates Act with Congressman Moore, who represents Utah’s First Congressional District. He shared his thoughts on how supporting and investing in the domestic PCB industry can help bolster American security.

Printed circuit board (PCB) reliability testing is generally performed by exposing the board to various mechanical, electrical, and/or thermal stimuli delineated by IPC standards, and then evaluating any resulting failure modes. Thermal shock testing is one type of reliability test that involves repeatedly exposing the PCB test board to a 288°C pot of molten solder for a specific time (typically 10 seconds) and measuring the number of cycles it takes for a board’s copper layer to separate from the organic dielectric layer. If there is no delamination, fabricators can rest assured that the board will perform within expected temperature tolerances in the real world.

From resplendent silks to ornate architectural marvels, India is perhaps best known for her rich cultural heritage. Until the late 1980s, it remained a relatively closed economy. But in 1991, former Prime Minister Rao passed a series of radical economic reforms that opened its doors to foreign trade and investment. Since then, India has been steadily developing into a major economic powerhouse on the global landscape.

Harken back to the start of the millennium, which rung in several historically defining events: Ramifications of Y2K were dispelled (to global relief), George Bush defeated Al Gore in the 54th U.S. presidential election, and AOL combined with Time Warner in a $165 billion merger, signaling the convergence of old and new media. This significant moment in history also marked the onset of decay for PCB fabrication in America.

Although I fell into the PCB world somewhat accidentally, I remember the exact moment I knew I wanted to become a material scientist. At an undergraduate engineering information fair, I saw the breadth of research possible within the materials science discipline. Superconductors. Synthesizing gold nanoparticles for cancer cell detection. Organic photovoltaics. It was all endlessly fascinating, and my curiosity drove me to ask, What’s possible? And more importantly, what’s next? I didn’t know the answers. But I knew deep down that I needed to be a part of it.
