Manufacturing Advantages
- Hybrid Stack-up Design: Combines an RO4350B RF layer (for high performance) with FR4 inner layers (to reduce costs), offering an excellent price-to-performance ratio.
- Low Loss (Df 0.0037): Minimizes RF signal attenuation; ideal for power amplifiers and antennas.
- Stable Dk (±0.05): Ensures consistent impedance and low signal reflection.
- Low Moisture Absorption: Provides dimensional stability and strong environmental adaptability.
- Fiber-Weave Effect Control: Utilizes spread-glass or homogenized-glass technology to ensure superior phase consistency.
- Optional HVLP Copper Foil: Reduces conductor loss—a critical factor for millimeter-wave (mmWave) applications.
- Mature Manufacturing Process: Highly compatible with standard FR4 fabrication, ensuring ease of processing and cost-effectiveness.
