Silicon Nitride（Si3N4）Ceramics Standard size substrate
 |
Silicon nitride(Si3N4) ceramic substrates are made using the sheet-forming method. In order to popularize electric vehicles, clean energy, etc., power semiconductors have excellent characteristics for smaller size, lighter weight, and higher output, and silicon nitride substrates are attracting attention as alternatives to Alumina and AlN substrates.
Specification
- High Electric Insulation Performance.
- High thermal Conductivity (80W/mK)
 Size □75×0.32 |
 Size 138×190×0.32 |
| Size | Thickness |
| □75 | 0.32 ±0.03 |
| 138×190 | 0.32 ±0.03 |
