1. Rogers DiClad 870 PCB Introduction
Rogers DiClad 870 PCB utilizes woven fiberglass reinforced PTFE composites with optimized material composition to achieve lower dielectric constant values. By incorporating fewer woven fiberglass plies and higher PTFE content, these laminates deliver reduced dielectric constant and dissipation factors while maintaining mechanical integrity at standard thickness levels, providing enhanced high-frequency performance for advanced RF applications.
