Electrical Ceramic DBC Substrate For Power Electronics

The description of DBC Ceramic Substrate:

1.Material: 96% alumina, aluminum oxide

2.Base layer:Molybdenum-Mananese(Mo/Mn) and Tungsten (W) optional

3. Thickness of metallization: from 10 to 40 micrometers (µm)

4. Thickness of metallic plating: nickle with 2~6 µm, copper with customized thickness

5.These Metallized ceramics are ideal for high voltage, high vacuum and high pressure applicationos.
 So far the most widely-used and effective method for creating a leak-tight, robust joint between ceramic and metal is by brazing. A thin layer of metal deposited on a ceramic part enables brazing between ceramic and metal part that h as a different coefficient of thermal expansion.

A layer of Molybdenum-Manganese is deposited with a typical thickness of 8 to 30 µm after sintering.The metallized surface receives a secondary coating of nickel to seal and improve wettability for later brazing.

Typical application:

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

Semiconductor Refrigeration Products
