DBC (Direct Bonding Copper) is the direct mating of two dissimilar electronic materials (Copper and Ceramic). The interface between the pure copper and the ceramic is very reliable.
1.Material:Alumina/ZTA/Si3N4.
2.Function:Insulation and heat dissipation ceramics.
3.Type:Metallized ceramic.
4.Can be customed:yes,please provide drawings for specific products.
DBC ceramic Substrate for power electronic
Product Description:
One of the main advantages of the DBC vs other power electronic substrates is their low coefficient of thermal expansion, which is close to that of silicon (compared to pure copper). This ensures good thermal cycling performances (up to 50,000 cycles).
