DBA

Direct Bonded Aluminum

DBA (Direct Bonded Aluminum) substrates are electronic components in which aluminum is directly bonded to a ceramic substrate such as aluminum nitride (AlN) or alumina (Al₂O₃), and then forming an aluminum circuit. With excellent thermal shock resistance and electrical characteristics, it is an ideal material for high-voltage, large-current power devices.
Applications include Renewable energy, Electric trains, EVs, and more.
