Rogers high-frequency PCB materials, particularly the RT/duroid 5880 series, are high-performance circuit board materials specifically designed for high-frequency applications. Below are some of their key features:
- Low Dielectric Constant (Dk): The dielectric constant of RT/duroid 5880 is extremely low, measuring 2.20±0.02 at 10GHz, helping to reduce signal delay and dispersion during transmission.
- Low Dielectric Loss: The material’s dissipation factor (Df) is only 0.0009 at 10GHz, meaning minimal signal loss during transmission.
- Low Moisture Absorption: With a water absorption rate of just 0.02%, it maintains stable electrical performance even in high-humidity environments.
- Excellent Machinability: The material is easy to cut, drill, and process, accommodating various complex shapes and designs in circuit boards.
- Chemical Resistance: Resistant to chemicals used in processing, including etching and plating solutions.
- Consistent Electrical Properties Across a Wide Frequency Range: Maintains stable dielectric constant and loss over a broad frequency range, making it ideal for high-frequency applications.
- Low Coefficient of Thermal Expansion (CTE): Features a low Z-axis CTE, enhancing dimensional stability.
- Lightweight Material: Certain models, such as RT/duroid 5880LZ, have low density, making them suitable for weight-sensitive applications.
- Good Mechanical Properties: High strength and rigidity allow it to withstand mechanical stress.
- High Reliability: Suitable for applications with stringent reliability requirements, such as aerospace and military fields.
- Compliance with Lead-Free Processing Standards: Meets environmental and industrial standards.
Typical Applications of Rogers High-Frequency PCB Materials Include:
- Commercial Avionics: Used in aircraft communication and navigation systems.
