96 Al2O3 Alumina Ceramic Substrates
- MSJ/CS-001
- 96% alumina ceramic
- customized
- 100 pcs per type
- electronic circuits or modules
96% Alumina substrates are the most cost-effective and commonly used ceramic substrate for thick film electronics or power powdules, they are made of electrically insulated 96% alumina (al2o3) ceramic. Alumina substrates have advantages of good electrical insulation, low dielectric properties, good heat resistance and wear resistance. The good thermal conductivity will help electronic modules to dissipate heat efficiently. The shape is stable because of the high strength and good durability, the surface is smooth and flatness is as good as 2‰ of dimensions.
