RO3206 2-Layer 25mil PCB – Ceramic-Filled Woven Glass RF Substrate with Immersion Gold for Automotive & Wireless Systems
1.Introduction of RO3206
Rogers' RO3206 high frequency circuit materials are ceramic-filled laminates reinforced with woven fiberglass. These materials are engineered to offer exceptional electrical performance and mechanical stability at competitive prices. The RO3206 high frequency materials were designed as an extension of the RO3000 series high frequency circuit materials with one distinguishing characteristic - improved mechanical stability.
