As the demand for high-performance printed circuit boards (PCBs) continues to rise, driven by advancements in technology and increasing complexity of electronic devices, the introduction of the Rogers RO3003 High-Frequency PCB marks a significant milestone in the industry. Designed specifically for commercial microwave and RF applications, this innovative PCB offers exceptional performance characteristics that make it ideal for a variety of advanced uses, including automotive radar, advanced driver assistance systems (ADAS), and 5G wireless infrastructure.
Understanding Rogers RO3003: The Material Advantage
The Rogers RO3003 PCB is constructed from ceramic-filled PTFE composites, which provide numerous advantages over traditional PCB materials. One of the standout features of the RO3003 laminate is its excellent stability of dielectric constant (Dk) across varying temperatures and frequencies. This stability eliminates the step change in Dk that often occurs near room temperature with PTFE glass materials, ensuring reliable performance in critical applications.
Key Features and Specifications
1. Dielectric Constant: The RO3003 PCB has a Dk of 3 ± 0.04 at 10 GHz and 23°C. This low and stable Dk is essential for maintaining signal integrity in high-frequency applications.
2. Dissipation Factor: With a dissipation factor of 0.001 at 10 GHz and 23°C, the RO3003 minimizes signal loss, making it suitable for applications that require high efficiency and low power consumption.
3. Thermal Stability: The RO3003 laminate boasts a thermal degradation temperature (Td) greater than 500°C, ensuring reliable performance even under extreme thermal conditions.
4. Thermal Conductivity: At 0.5 W/mK, the thermal conductivity of the RO3003 allows for effective heat dissipation, which is crucial in high-power applications where overheating can lead to component failure.
5. Absorption: With a moisture absorption rate of only 0.04%, the RO3003 PCB maintains its properties in various environmental conditions, further enhancing its reliability.
6. Coefficient of Thermal Expansion (CTE): The low CTE values (X-axis: 17 ppm/°C, Y-axis: 16 ppm/°C, Z-axis: 25 ppm/°C) ensure that the PCB maintains its dimensional stability across a wide temperature range, which is critical for multi-layer board designs.
