Plain substrates
Toshiba Materials' silicon nitride ceramic substrates have both heat dissipation and strength.
They are used in electronics fields such as power semiconductor modules, inverters and converters, replacing other insulating materials to increase production output and reduce size and weight.
Their extremely high strength also makes them a key material that increases the life and reliability of the products they are used in.
Features
- Among the best in the world for heat dissipation and strength
- Enables designs involving drilling and screwing or pressure welding, methods that are usually difficult
