Ceramic substrates, such as alumina (Al2O3) and aluminum nitride (AlN), offer superior thermal conductivity (30-180 W/mK) and insulation properties compared to metal-based substrates (under 5 W). Al2O3 is cost-effective but has lower thermal conductivity, while AlN performs better thermally. Ceramic substrates enable direct component mounting, offering better heat dissipation and potential for multi-layer designs.
