Ceramic PCB boards offer excellent thermal conductivity and insulation, making them ideal for heat dissipation applications in industries like LED lighting and high-power modules. Compared to regular PCB boards, ceramic PCB boards are made of different materials and have different applications, while a combination of ceramic and high-frequency boards may be necessary in certain scenarios. When selecting ceramic substrates, it is important to consider quality parameters, craftsmanship, conduct trials, and research information from reputable manufacturers.
