What is a Hybrid PCB?

A hybrid PCB (also known as a mixed-material PCB) is a specialized circuit board that integrates two or more distinct base materials in its stack-up, each selected to optimize specific performance attributes. Unlike single-material PCBs, which must compromise on certain properties, hybrid PCBs leverage the strengths of each material to address diverse design requirements.

Rogers RO4350B Material Overview

Rogers RO4350B is a proprietary laminate composed of woven glass reinforcement blended with hydrocarbon/ceramic compounds, striking a balance between PTFE/woven glass-like electrical performance and the manufacturing simplicity of epoxy/glass materials.

Tailored for high-frequency applications, RO4350B laminates offer tightly controlled dielectric constant (Dk) and maintain ultra-low signal loss—all while being processable using standard epoxy/glass manufacturing workflows. A cost-effective alternative to traditional microwave laminates, RO4350B eliminates the need for specialized through-hole treatments or handling procedures required by PTFE-based materials. It also holds a UL 94 V-0 flammability rating, making it suitable for active electronic devices and high-power RF designs.
