      DBC Ceramic Substrate(Nickle Plating)

      Time:2015-09-17

      Direct Bonding Copper Ceramics substrate:
      DBC is a new high performance substrate materials that according to customer requirements of the circuit diagram directly bond copper (99.99%) and alumina ceramic substrate together , and the materials meet the ROHS requirements.

      Characteristics of DBC:
      DBC has excellent electrical insulation (anti voltage of 3KV ~ 14kV) and thermal conductivity, high temperature resistance, moisture resistance, corrosion resistance, dielectric performance and stability, good heat dissipation, (heat conduction coefficient 26 ~ 180w/m.K). Excellent thermal cycling performance, high reliability, Mechanical stress, and has high strength binding.

      Application of DBC:
      As a new and high capability substrate, DBC substrates have been used widely in electric power and electronic industry. The high thermal conductivity of Al2O3 combined with the high thermal capability of thick high purity copper make DBC the most popular material choice for power chip on board assemblies.

      Nickle Plating DBC Ceramic Substrate:
      Ceramic metallized: nickel(Ni)
      Ni layer thickness of 2-10um, phosphorus and nickel, can effectively prevent the diffusion of copper ions.
