High-Performance RO3003 HDI PCB 4-Layer 1.6mm Thick Circuit Boards for Advanced Applications
(Custom PCBs are tailored products; the images and specifications provided are for reference only.)
Introduction to RO3003
Rogers RO3003 high-frequency laminates are ceramic-filled PTFE composites designed for commercial microwave and RF applications. These laminates provide excellent stability of dielectric constant (Dk) across various temperatures and frequencies, eliminating the typical step change in Dk seen with PTFE glass materials. This makes RO3003 ideal for automotive radar (77 GHz), advanced driver assistance systems (ADAS), and 5G wireless infrastructure (mmWave).
