Super Heat Dissipation Substrate AtsuDo™

PHOTO: Super Heat Dissipation Substrate AtsuDo™

Excellent endothermic performance, utilizing copper's 386W/m·K thermal conductivity

- Thick copper (more than 1mm thickness) bonded on
  top of strong ceramic substrate
- Excellent transient heat dissipation, with high heat
  capacity of thick copper
- High electrical insulation as well as heat dissipation
  by using silicon nitride as substrate
- Substrate can also be made from other ceramic
  materials. Please contact us for possibility.
