Direct Bond Copper DBC Ceramic Substrate for PCB

Given the properities of good heat transfer properties, vacuum tightness and minimum electric resistance, alumina Metallized ceramics are an ideal components for high vacuum ,high voltage and high pressure applications.

By applying a thin metallic coating(general Mo/Mn), by then following covered with plating, like Nickel/Copper/Gold...to the surface of the ceramic,, the welding between ceramic and metal can be achieved, which is also known as Ceramic metallization. Since tungsten and moly-Manganese metallizations have higher adhesion to the substrate than Thick-film metallization, sometimes, it's a prferred option.

DBC (Direct bonded copper) , has excellent electrical insulation, high thermal conductivity, good solderability and high strength.It's widely used for connecting high-power semiconductor electronic circuits.

Typical application:

High-Density Hybrid Circuits, Microwave Power Devices,  Power Semiconductor Devices, Power Electronic Devices, Optoelectronic Components,

Semiconductor Refrigeration Products
