Introduction of Rogers RO3210 Substrate

RO3210 is a high-performance woven glass-reinforced ceramic-filled PTFE laminate categorized under Rogers RO3200™ high-frequency material series. As an upgraded iteration of the classic RO3000® series, it boasts drastically improved mechanical stability while retaining premium electrical properties. This advanced dielectric material combines the ultra-smooth surface of non-woven PTFE for fine-line etching precision and the rigid structural strength of woven glass composites, perfectly catering to sophisticated multilayer RF PCB designs.

Produced under ISO 9002 certified quality management systems, RO3210 is fully compatible with conventional PTFE fabrication workflows. It features a fixed dielectric constant of 10.2 and a low dissipation factor of 0.0027, maintaining ultra-stable low-loss characteristics across microwave frequency bands. With copper-matched thermal expansion coefficient and superior dimensional stability, this substrate is highly suitable for epoxy hybrid lamination and high-yield mass commercial production.
