Key Properties of High-Speed Rogers PCB Materials: High Speed PCB Material Rogers

Dielectric Constant (Dk) and Signal Integrity

The dielectric constant (Dk) is one of the most critical properties of high-speed PCB materials as it affects the speed at which signals propagate through the substrate. For high-speed applications, maintaining a low and stable Dk is essential to preserve signal integrity, minimize distortion, and ensure controlled impedance. High speed PCB material Rogers provides a range of laminates with low and consistent Dk values, such as RO4003C (Dk = 3.38), RO4350B (Dk = 3.48), and RT/duroid 5880 LZ (Dk = 1.96), ensuring minimal signal delay and improved signal performance.

Another important consideration is the consistency of the dielectric constant with temperature changes, commonly referred to as the thermal coefficient of dielectric constant (TCDk). High speed PCB material Rogers maintains stable Dk values across a wide temperature range, minimizing signal drift in high-frequency environments. For instance, RO3003 and RO3006 exhibit exceptional TCDk stability, making them ideal for applications where temperature fluctuations can impact signal integrity. Consistent Dk values enable reliable impedance control and predictable performance across varying operating conditions.

Dissipation Factor (Df) and Loss Tangent

Dissipation factor (Df), also known as the loss tangent, determines how much signal energy is lost as heat as signals propagate through the PCB material. A low Df is crucial in high-speed designs because it reduces signal attenuation and maintains signal strength over longer distances. High speed PCB material Rogers offers laminates with exceptionally low Df values, ensuring minimal energy loss and optimal signal integrity.

For example:
