This 4-layer rigid PCB uses Rogers RT/duroid 5880 (glass microfiber reinforced PTFE composite) as the core substrate, laminated with TG170 FR-4 prepreg. Specifically designed for high-precision stripline and microstrip circuits, RT/duroid 5880 features uniform dielectric constant (panel-to-panel and wide frequency range) and low dissipation factor (applicable to Ku-band and above). With excellent dielectric properties and lead-free compatibility, it meets rigorous high-frequency transmission requirements, suitable for precision RF, microwave and millimeter wave applications.

Rogers RT/duroid 5880 Material Introduction
Rogers RT/duroid 5880 is a high-performance PTFE-based composite laminate, renowned for its excellent dielectric properties and stable electrical performance across a wide frequency range (8 GHz to 40 GHz). It exhibits ultra-low dielectric loss, low moisture absorption, and superior thermal stability, making it an ideal choice for high-frequency RF and microwave applications. The material is fully compatible with lead-free processes and meets UL 94 V-0 flammability requirements, ensuring reliable fabrication and long-term operational stability.
The combination of PTFE matrix and reinforcing fibers endows RT/duroid 5880 with excellent mechanical properties, including high tensile and compressive strength, as well as good copper peel strength. Its low thermal expansion coefficient and stable temperature coefficient of dielectric constant ensure consistent performance under extreme temperature conditions (-50℃ to 150℃), making it suitable for harsh environment applications such as aerospace and high-reliability communication systems.
