| 1. Alumina ( Al2O3 substrate ) |
|
Al2O3 substrate is the most popular ceramic substrate, with excellent heat
resistance, high mechnical strength , abrasion resistance and small dielectric
loss .The surface of alumina substrate is quite smooth and low porosity ,
99.6%
alumina substrate is suitable for thin film device , 96% alumina
substrate is
suitable for thick film device application .
|
|
| |
|
2. Aluminium Nitride ( AlN substrate )
|
|
Aluminium Nitride has higher thermal conductivity , compared to alumina
substrate It is about 7 to 8 times high . AlN substrate is an excellent electronic
package material .
|
|
| |
|
3. Zirconia ( ZrO2 substrate )
|
|
Compared to alumina substrate , ZrO2 substrate has higher mechanical
strength and fracture toughness it's about three times higher for bending
strength, two times for fracture toughness than alumina substrate . ZrO2
( zirconia ) also provides good abrasion resistance. It features a thermal
expansion rate close to metals .
