RF-10 High Frequency PCB
Introduction
RF-10 laminates are a composite material consisting of ceramic
filled PTFE and woven fiberglass. These laminates offer several
advantages, including a high dielectric constant and low
dissipation factor. The incorporation of thin woven fiberglass
reinforcement provides a dual benefit of low dielectric loss and
improved rigidity, making the material easier to handle and
enhancing its dimensional stability for multilayer circuits.
RF-10 laminates demonstrate low coefficients of expansion in the X,
Y, and Z directions. This characteristic ensures exceptional
reliability for plated through hole connections and reduces the
scaling factors required for artwork compensation.
Features and Benefits
RF-10 has a dielectric constant of 10.2 ± 0.3 and a dissipation
factor of 0.0025 at 10 GHz. This high dielectric constant enables
the reduction of RF circuit size, while the low loss tangent
minimizes signal loss and maintains excellent signal quality.
RF-10 exhibits a thermal conductivity of 0.85 W/M*K when unclad.
This property allows for efficient dissipation of heat generated by
the circuit, ensuring optimal performance even in demanding thermal
conditions, and preventing overheating.
RF-10 laminates demonstrate exceptional adhesion to smooth copper
surfaces, ensuring strong and reliable bonding between the laminate
and the copper.
RF-10 has a coefficient of thermal expansion (CTE) of 16 ppm/°C in
the X-axis, 20 ppm/°C in the Y-axis, and 25 ppm/°C in the Z-axis.
These low coefficients of expansion in all three directions
contribute to stable and reliable plated through hole connections,
enhancing the overall reliability of the PCB.
