Aluminum nitride ceramics: Thin metallized film substrates

Our aluminum nitride ceramic substrates with thin metallized film are among the world's best for heat dissipation. Our range includes thin titanium, platinum and gold film, gold tin soldering of patterns and sub-mounting with gold bumps. These substrates are used in a wide range of fields from laser diodes to LEDs for general lighting, high-power LEDs for headlights and deep UV LEDs that are currently in demand for purposes such as sterilization lamps and resin hardening lamps due to their high heat dissipation.
