CuClad 233 High Frequency PCB
Introduction
Rogers CuClad 233 laminates are cross plied, woven fiberglass and PTFE composite laminates that offer a low dielectric constant value of 2.33.
CuClad 233 laminates use a medium fiberglass/PTFE ratio to balance the lower dielectric constant (Dk) and improved dissipation factor without sacrificing mechanical properties. The CuClad 233 laminates have a cross plied construction that provides greater dimensional stability with balanced electrical and mechanical properties.
Features
CuClad 233 has a dielectric constant (Dk) of 2.33, indicating its ability to support efficient signal transmission and minimize signal loss. This feature is crucial for high-frequency applications where signal integrity is paramount.
It features a low dissipation factor (Df) of 0.0013 at 10 GHz, exhibiting minimal energy loss during signal transmission. This characteristic helps reduce circuit losses and maintain signal integrity, particularly in high-frequency scenarios.
CuClad 233 possesses low moisture absorption, preventing the ingress of water molecules that could affect the PCB's electrical properties.
It also exhibits low out-gassing, reducing the risk of trapped gases that could lead to performance issues or delamination.
CuClad 233 maintains a stable dielectric constant across a wide frequency range. This stability ensures consistent electrical performance throughout different frequencies, contributing to reliable signal transmission.
