Insulated Substrates with Aluminum Circuit for Power Modules
Features
DBA (Abbreviation of "Direct Bonded Aluminum") is a registered trademark of Mitsubishi Materials Corporation.
DBA Substrate is made by high purity aluminum plates bonded to both sides of a ceramic substrate.
DBA Substrate have a dual function of electric insulation and heat dissipation from the mounted silicon dies.
DBA substrate have high reliability in severe thermal cycle test. DBA substrates are used in the power modules of
Electric Vehicles (xEVs) and the other applications requiring high reliability and heat dissipation.
Application Examples
Hybrid car, EV, fuel-cell car, electric train, power-conditioner for solar power / wind power generator, invertor, power module, isolated board, radiation board
