TC600 High-Thermal-Conductivity PCB with Immersion Gold Finish

1.Product Overview

Rogers TC600 is a premium PTFE-based composite laminate engineered with thermally conductive ceramic fillers and woven glass reinforcement. Designed for high-power RF applications, this material delivers best-in-class thermal conductivity (1.1 W/mK) while maintaining excellent dielectric stability (Dk=6.15). The 2-layer construction features 1oz copper layers and immersion gold finish, making it ideal for compact power amplifiers, microwave combiners, and avionics systems.
