Product Characteristics
1. Dielectric Properties
1.1 Ultra-low dissipation factor (Df≈0.001–0.002): Minimizes high-frequency signal loss (e.g., insertion loss <0.3dB/inch @80GHz).
1.2 Stable dielectric constant (Dk=2.0–2.2): Dk variation <±0.05 across temperature/frequency, ensuring impedance consistency.
2. High-Frequency Advantages
2.1 THz-ready: Ideal for 5G mmWave (24-100GHz), satellite comms (Ka/Q-band), terahertz imaging.
2.2 Phase stability: Group delay variation <1ps/m, critical for phased-array radar beamforming.
3. Reliability & Environmental Resistance
3.1 Wide temperature range (-200°C to +260°C): Suitable for spacecraft exteriors and cryogenic radars.
3.2 Chemical inertness: Resists strong acids/alkalies/solvents, ideal for medical sterilization or chemical industries.
4. Mechanical & Thermal Properties
4.1 Low CTE (≈100ppm/℃): Matches copper foil CTE, mitigating delamination during thermal cycling.
4.2 High-thermal-conductivity variants available (e.g., Rogers TC series >0.8W/mK) for power amplifier cooling.
5. Manufacturing Challenges
5.1 Surface activation required: Sodium-etching/plasma treatment ensures copper adhesion >1.0N/mm.
5.2 Precision drilling: Laser-drilled vias require wall roughness <10μm to suppress signal reflection.
