Why Is Low Dielectric Loss Critical for Ceramic PCB?
Low dielectric loss is a critical attribute of ceramic PCB, particularly for high-frequency applications like 5G communication, aerospace navigation, and radar systems. Dielectric loss refers to the energy dissipated as heat when an electric field is applied to the PCB substrate. Ceramic PCB board with low dielectric loss minimizes signal attenuation, ensuring reliable data transmission at high frequencies. A professional ceramic PCB manufacturer selects materials with low dielectric constants (such as alumina and aluminum nitride) and optimizes ceramic PCB manufacturing processes to reduce dielectric loss. This is essential for applications requiring high signal integrity, such as satellite communication and military radar systems, where even minor signal loss can compromise performance. Ceramic PCB fabrication techniques like DBC and AMB ensure a smooth, uniform substrate surface, further reducing dielectric loss. When requesting ceramic PCB quotes for high-frequency applica...
