The RO4003C Low Profile PCB leverages Rogers’ proprietary technology, which combines reverse treated foil with standard RO4003C dielectric. This unique construction results in a laminate that not only reduces conductor loss but also enhances signal integrity, making it ideal for high-frequency applications.
The integration of hydrocarbon ceramic materials allows for superior performance at high frequencies while maintaining cost-effectiveness in manufacturing. This PCB can be fabricated using standard epoxy/glass (FR-4) processes, eliminating the need for specialized via preparation techniques, thus reducing overall production costs.
Key Features
The RO4003C Low Profile PCB boasts several impressive specifications that cater to the needs of modern electronic designs:
Dielectric Constant: With a dielectric constant of 3.38 ± 0.05 at 10 GHz, this PCB ensures stable signal transmission and minimal signal degradation.
Dissipation Factor: A low dissipation factor of 0.0027 at 10 GHz indicates reduced energy loss, enhancing overall efficiency.
Thermal Stability: The PCB has a thermal decomposition temperature (Td) greater than 425°C and a high glass transition temperature (Tg) exceeding 280°C, ensuring reliability under high-temperature conditions.
Thermal Conductivity: With a thermal conductivity of 0.64 W/mK, it effectively dissipates heat, which is crucial for maintaining performance in high-power applications.
Low Coefficient of Thermal Expansion (CTE): The Z-axis CTE is 46 ppm/°C, closely matched to copper, which minimizes stress and potential failures during thermal cycling.
