Rogers RO4835 Material Introduction

Rogers' RO4835 laminate offers enhanced stability at high temperatures and is more resistant to oxidation than other hydrocarbon materials. RO4835 laminates share similar electrical and mechanical properties with RO4350B laminates and are designed for high frequency performance and cost-effective circuit fabrication. It uses standard epoxy/glass (FR-4) processes and is competitively priced.

RO4835 laminates are a low loss material that offer low cost circuit fabrication. These laminates are available with Rogers proprietary LoPro Reverse treated copper foil, ideal for applications requiring low insertion loss.
