Product Overview

Double-sided DBC (Direct Bonded Copper) ceramic substrates are advanced circuit carriers designed for high-power electronic applications. By bonding copper layers directly onto both sides of a ceramic substrate (typically alumina, aluminum nitride, or silicon nitride), these substrates provide excellent thermal conductivity, high current carrying capacity, and strong mechanical integrity.

The double-sided copper structure enables efficient heat dissipation and flexible circuit design, making DBC substrates ideal for power modules and high-reliability systems.
