Metalized Alumina Substrate DBC DPC Ceramic Substrate

Alumina ceramic metalized substrates are ceramic copper-clad plates with electrical conductivity, thermal conductivity, and high insulation properties, formed by metalizing alumina ceramic substrates with copper. The alumina metalized substrates can be processed through various techniques. When combined with the DBC (direct bond copper) process, they become DBC alumina ceramic copper-clad substrates. Similarly, when integrated with the DPC (direct plated copper) process, they transform into DPC alumina copper-clad substrates.
