Product Description :    
Alumina (AL2o3) DBC substrates can directly bonds copper foil to the surfaces of Alumina ceramic DBC substrates under high temperature using DBC OR DCB (Direct Bond Copper) Technology.
 
Product Feature :  
The composite made by it possesses good electric insulation capacity, high heat conductivity, superior soft solderability and high adhesion. Additionally, it can also etch different graphs just like PCB plate, and a large current carrying capacity. Therefore, DBC substrate has been used as the basic material in electric & electronic industry at home and abroad.
