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.
