Introduction of Rogers RO3003 Substrate

RO3003 is a premium ceramic-filled PTFE composite laminate belonging to Rogers’ reputable RO3000 high-frequency material series. Developed for commercial microwave and radio frequency applications, this substrate delivers consistent electrical performance and superior mechanical durability at an economical price point. Distinct from conventional high-frequency dielectrics, the RO3000 series maintains uniform mechanical properties regardless of dielectric constant variation, enabling reliable multi-material hybrid stacking without warpage or structural defects.

RO3003 features copper-matched thermal expansion characteristics for exceptional dimensional stability under temperature cycling. Its X/Y-axis CTE is 17 ppm/°C, while the Z-axis CTE measures 24 ppm/°C, greatly enhancing plated through-hole robustness in extreme thermal environments. Boasting ultra-low dielectric loss and frequency-immune Dk stability, this material supports dependable signal transmission up to 77 GHz. Compatible with standard PTFE fabrication workflows, it serves as a cost-efficient solution for high-volume RF circuit manufacturing.
