In the series wrap-up, Marcy LaRont discusses with CTO Kirk Thompson the turning point facing the PCB industry as innovation speeds up. With increasing data rates, power density, AI infrastructure, flexible electronics, photonics, and chiplet integration, traditional material assumptions are no longer enough. Kirk explains how advanced materials now enable higher speeds, better thermal management, and more precise dimensional control, while balancing manufacturability. The merging of PCBs and advanced packaging is both exciting and challenging, requiring substrate-like precision at scale. In the end, early collaboration across the ecosystem and smarter, more integrated materials will shape the next generation of cutting-edge PCBs.
