Unlike standard FR-4 boards, Rogers materials offer tailored dielectric properties, resulting in lower signal loss, improved impedance control, and enhanced thermal management, which are crucial for demanding applications. This section will delve into the distinct attributes of several popular Rogers materials and their influence on the overall PCB cost.

The dielectric constant (εr) determines the speed of signal propagation and impedance, while the dissipation factor (tan δ) indicates signal loss. Lower values of tan δ translate to better signal integrity. As illustrated in the table, RO3003 and 5880 have the lowest dissipation factors which explains their application in extremely high-frequency applications. The unique combination of these electrical properties, thermal stability, and mechanical robustness of each material impact their manufacturability, supply chain dynamics, and ultimately, the cost of the PCB.
