The Companion Guide to... PCB Materials: The Backbone and Future of Electronics

PCB materials are critical to modern electronics, acting not just as structural supports but as active systems that influence performance, reliability, sustainability, and manufacturability. This companion guide expands on the 6-part podcast series, emphasizing that material selection must occur early and consider electrical, thermal, mechanical, and environmental factors to avoid failure and inefficiency. It highlights the importance of designing for long-term reliability, high-speed performance, and harsh environments while balancing sustainability and supply chain resilience. As technologies like AI, electrification, and advanced packaging evolve, materials are becoming strategic enablers of innovation, requiring integrated, system-level thinking across the entire electronics ecosystem.

Since returning to the U.S. from his role in Asia, he has worked closely with major industry OEMs to develop and qualify Isola materials for the next generation of technology. In his current position, Michael provides product application training, collaborative design support, and design reviews for selecting the right material across a wide range of applications, including high-speed digital, high energy/voltage, CAF resistance, and RF/MW.

Michael is active in various PCB industry organizations where he currently provides technical expertise to industry critical committees and projects.

He received his Bachelor of Science degree in Mechanical Engineering and Master of Business Administration from Portland State University.

Isola is a global leader in material sciences that began production of insulation materials in 1912 as Continentale Isola Werke AG in Düren, Germany. In 1956 Isola began production of copper clad phenolic phenolic-paper laminates. Since then, the company has acquired or merged with numerous laminate and prepreg manufacturers such as Allied Signal, Norplex, Westinghouse, and Polyclad to become one of the most recognized global brands in the industry.

Today, Isola designs, develops, manufactures and distributes copper-clad laminates and dielectric prepregs used to fabricate multilayer printed circuit boards. These materials span a range of applications from low cost, high performance FR-4 epoxy systems to ultra low loss dielectric materials.

Isola has seven manufacturing facilities, three R&D facilities, three state-of-the-art analytical services laboratories and numerous technical support and sales teams across Asia, Europe, and the North America. Our global presence enables Isola to service customers around the world.
