Product Description

High Thermal Conductivity Hot-pressed Sintered Silicon Nitride Sheet for Electronic Components

High thermal conductivity hot-pressed sintered silicon nitride sheets are advanced materials that have gained widespread attention in recent years due to their excellent performance and potential applications in various industries. These substrates are produced by mixing silicon nitride powder with a binder, followed by sintering to obtain a dense and highly thermally conductive material. Silicon nitride substrates are widely used as substrates for electronic components such as microprocessors,power electronics, and RF modules due to their high thermal conductivity and electrical insulation properties. They help dissipatethe heat generated by electronic components, ensuring their reliable and efficient operation.

 

Advantages of high thermal conductivity hot-pressed sintered silicon nitride sheets:
