4.1 RO3210 High Frequency Circuit Laminate Overview

Rogers RO3210 laminate belongs to the professional RO3200 series high-frequency circuit laminates developed by Rogers, a upgraded extension of the classic RO3000® series high-frequency substrate materials. This high-performance CCL is a ceramic-filled laminate reinforced with woven glass fiber, precisely engineered to deliver outstanding electrical performance and superior mechanical stability at a cost-effective price point. Differentiated from conventional high-frequency substrates, Rogers RO3200 series integrates dual core advantages: the ultra-smooth surface of non-woven PTFE laminates and the structural rigidity of woven-glass PTFE laminates. This unique composite structure enables finer line etching tolerance and stable overall board performance. Compliant with standard PTFE PCB fabrication procedures specified in official RO3000 series processing guidelines, RO3210 PCB substrate features a fixed dielectric constant of 10.2 and an ultra-low dissipation factor of 0.0027, delivering consistent low-loss performance for microwave and RF circuit applications. All RO3200 series laminates are produced under strict ISO 9002 certified quality management systems to ensure standardized and reliable product quality.
