Aluminum nitride ceramics:
Our aluminum nitride ceramic substrates are among the world's best for heat dissipation. Our insulating heat dissipation substrates have thermal conductivities ranging from 160 to a maximum of 255W/(m K), making them ideal for areas requiring high heat dissipation or those requiring a somewhat thick substrate that can withstand high voltages.
They are also ideal for use as semiconductor substrates as they have a similar thermal expansion rate to silicon, silicon carbide, gallium nitride and gallium arsenide chips.
- A lineup with high heat dissipation and a wide variety of thermal conductivity
- We also have a range of substrates with thin metallized film.Link
