Plain substrates
Our aluminum nitride ceramic substrate has high heat dissipation. Our insulating heat dissipation substrates have thermal conductivities ranging from 170 to 250W/(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.
Features
- 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
