RO4003C PCB

Core Advantages of Rogers RO4003C Low-Loss PCB

• Ultra-Low Signal Loss: RO4003C substrate features an industry-leading low dissipation factor (Df = 0.0027 @ 10GHz), minimizing insertion loss and signal attenuation even at millimeter-wave frequencies up to 40GHz+.
• Exceptional Dielectric Stability: Tightly controlled dielectric constant (Dk = 3.38 ± 0.05 @ 10GHz), with an ultra-low thermal coefficient of dielectric constant (40ppm/℃) across -50℃ to 150℃ temperature range, ensuring consistent RF performance in fluctuating operating environments.
• Superior Thermal & Mechanical Reliability: Matched Z-axis coefficient of thermal expansion (CTE 46ppm/℃) to copper foil, reducing thermal stress during reflow soldering and temperature cycling; with a Tg >280℃, it maintains stable mechanical properties through high-temperature processing and operation, improving long-term reliability for high-reliability applications.
• Easy Manufacturability: Unlike PTFE-based high-frequency materials, RO4003C uses standard FR-4 PCB fabrication processes, no special through-hole treatment or plasma etching required, reducing production costs and lead times while ensuring consistent batch quality.
• Global Compliance: Fully RoHS and REACH compliant, supporting seamless market access for commercial, industrial, aerospace, and automotive products worldwide.
