AI Overview
Rogers RT/duroid 5870 high-frequency laminates are PTFE (polytetrafluoroethylene) composites reinforced with glass microfibers, specifically designed for demanding stripline and microstrip circuit applications. They are widely used in high-frequency, high-speed applications such as aerospace, military radar, and communication systems due to their low dielectric constant (Dk) and low dielectric loss.
Key Material Properties
- Dielectric Constant (Dk): at 10 GHz (operating temperature), which remains stable across a wide range of frequencies.
- Dissipation Factor (Df): Extremely low, around 0.0012 at 10 GHz, reducing signal loss.
- Reinforcement: Randomly oriented glass microfibers provide consistent electrical properties and structural integrity.
- Thermal Stability: High thermal resistance () with a low Coefficient of Thermal Expansion (CTE), allowing for reliable operation in extreme environments.
- Moisture Absorption: Very low moisture absorption, which is critical for maintaining performance in humid conditions.
Advantages of RT/duroid 5870 PCBs
- Low Electrical Loss: Ideal for applications requiring minimal signal attenuation.
- Uniformity: The homogenous structure eliminates the inconsistency found in woven glass laminates.
- Easy Processing: Easily cut, sheared, and machined to shape, showing high resistance to solvents used in etching or plating.
- Versatile Applications: Suited for Ku-band and higher, including millimeter-wave applications.
Common Applications
- Commercial airline broadband antennas
- Military radar systems and missile guidance systems
- Point-to-point digital radio antennas
- Microstrip and stripline circuits
Fabrication Notes
- Surface Treatment: PTFE surface often requires chemical etching or plasma treatment to improve copper adhesion.
- Drilling: Requires specialized tools and controlled parameters to avoid debris and thermal damage.
- Available Thicknesses: Common substrate thicknesses include 10mil, 20mil, 31mil, and 62mil.
