With the rapid development of 5G communication, millimeter-wave radar, high-speed servers, satellite communication, and AI data processing systems, high-frequency and high-speed chips now require much higher PCB performance. Standard FR4 circuit boards often experience signal loss, unstable impedance, and electromagnetic interference under high-frequency conditions, making them insufficient for modern RF and high-speed systems. Rogers RO4350B hybrid high-frequency PCB boards combine high-performance RO4350B materials with FR4 hybrid stack-up structures, providing an excellent balance between high-frequency performance and manufacturing cost. With lower dielectric loss, stable impedance control, and superior high-frequency transmission capability, these hybrid high-frequency PCBs have become an important foundation for modern high-speed electronic devices.
