1. Microstructure: High-frequency PCBs feature relatively uniform grain size and distinct grain boundaries, providing superior hysteresis loss performance compared to ordinary metal sheets.
2. Material Properties: High-frequency PCBs exhibit exceptional material properties, including high magnetic permeability, high-temperature stability, high corrosion resistance, and high additivity.
3. Manufacturing Process: The manufacturing process for high-frequency PCBs is unique, requiring a variety of processes including electromagnetic induction heating, rolling, and cooling.
