RO3210 2-Layer 30mil ENIG PCB for High-Frequency Wireless and Automotive Applications
1.Introduction
Rogers' RO3210 high-frequency circuit materials are ceramic-filled laminates reinforced with woven fiberglass. These materials are engineered to deliver outstanding electrical performance and mechanical stability, with a unique combination of surface smoothness and rigidity. RO3210 laminates merge the fine-line etching tolerances of non-woven PTFE with the structural strength of woven-glass PTFE, making them suitable for standard PTFE PCB processing techniques.
