Compare Laminates Side by Side
Compare laminate classes side by side on the parameters that decide a high-speed channel — dielectric loss, dielectric constant, the interfaces they serve, and relative cost. Pick 2 or 3 to compare.
- DkSets trace geometry for impedance
- DfDrives loss on a digital channel
- $Relative cost, directional only
High-Speed Laminate Comparison
Pick 2 or 3 laminate classes — the lowest Df (loss) per row is highlighted.
High-Tg FR-4
Mid-loss
Low-loss (Megtron-class)
Ultra-low-loss
Lowest Df (loss) per row is highlighted. Select 2–3 classes.

Dk/Df ranges are representative published values from manufacturer datasheets, measured at GHz frequencies; exact figures vary by glass style, resin content, and test frequency. Relative cost is directional, not a quote. Df (dissipation factor) drives loss on a digital channel; Dk mainly sets the trace geometry for a target impedance.
