DCB

Direct Copper Bonding

DCB (Direct Copper Bonding) substrates are electronic components in which copper plates are directly bonded to a ceramic substrate such as alumina (Al₂O₃) or alumina zirconia (Al₂O₃/ZrO₂), and then forming a copper circuit. They are widely used in power devices that require both electrical insulation and efficient heat dissipation.
Applications include industrial equipments, power supplies, home appliances, automotive components, and more.
