Product Description

Innovacera Customized Copper Coated Alumina Ceramic Dbc Substrate

 

 
DBC substrate short for Direct Bonded Copper substrate is an advanced material composed of a ceramic substrate (typically Al2O3 or AlN) and copper, tightly joined together through a hypo-eutectic process. This unique combination of materials results in a substrate with exceptional thermal conductivity, low thermal expansion, high strength, and excellent wettability for soldering applications.
 
1. Thickness of substrate can be thin: 0.25mm,0.28mm,0.45mm,0.5mm,0.635mm,1.0mm,1.5mm, 1.8mm,2.0mm
2. Coating by Cu ,Mo/Mn,Ag, Plate with copper
3. Excellent thermal conductivity
4. High electrical insulation
