Aluminum nitride ceramics:
White tile (plain substrates)

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.

Aluminum Nitride Ceramics: White Tile (Plain Substrates)


  • Extensive range with among the best heat dissipation in the world
  • We also have a range of substrates with thin metallized film.Link
