1.Rogers RO4835 PCB Introduction
Engineered for high-frequency performance and cost-effective circuit fabrication, Rogers RO4835 2-Layer PCB leverages premium RO4835 laminate as its core base material. RO4835 advanced laminate delivers enhanced thermal stability at elevated temperatures and boasts superior oxidation resistance when compared to conventional hydrocarbon-based materials. Sharing closely matched electrical and mechanical characteristics with the renowned Rogers RO4350B laminates, Rogers RO4835 RF Circuit Board is optimized for reliable high-frequency operation while adhering to standard epoxy/glass (FR-4) manufacturing processes—enabling competitive pricing without compromising quality. As a low-loss material solution, it can be paired with Rogers’ proprietary LoPro Reverse treated copper foil, making it an ideal choice for applications that demand minimal insertion loss to ensure peak signal integrity.
