Rogers RO4350B Material Introduction

Rogers RO4350B materials are proprietary woven glass reinforced hydrocarbon/ceramics that combine electrical performance close to PTFE/woven glass with the manufacturability of epoxy/glass. These laminates offer tight control over dielectric constant (Dk) and maintain low loss while utilizing the same processing methods as standard epoxy/glass materials. Available at a fraction of the cost of conventional microwave laminates, RO4350B does not require the special through-hole treatments or handling procedures needed for PTFE-based materials. Additionally, RO4350B laminates are UL 94 V-0 rated, making them suitable for active devices and high-power RF designs.

Key Material Features

Benefits
