Introduction to RO3210 Material

Rogers RO3210 laminates are ceramic-filled PTFE materials reinforced with woven fiberglass, designed for high-frequency circuits requiring rigidity and excellent electrical performance. These laminates combine the smoothness of non-woven PTFE materials with the mechanical stability of woven-glass laminates, enabling consistent performance in complex high-frequency designs.

Key characteristics include:

• High dielectric constant (Dk): Provides precise signal control for RF applications.
• Low dissipation factor (Df): Ensures minimal signal loss and phase shift.
• Dimensional stability: Allows for high production yields and fine-line etching tolerances.

Features of RO3210

• Dielectric Constant (Dk): 10.2 ± 0.5 at 10GHz
• Dissipation Factor (Df): 0.0027 at 10GHz
• CTE (Coefficient of Thermal Expansion): X-axis: 13 ppm/°C, Y-axis: 13 ppm/°C, Z-axis: 34 ppm/°C
• Decomposition Temperature (Td): 500°C
• Thermal Conductivity: 0.81 W/mK
• Flammability Rating: UL-94 V0
