Product Description
Electrical-insulating aluminum nitride heat spreaders for power, laser and electronic thermal-management assemblies.
Aluminum nitride heat spreaders provide a ceramic path for moving heat while maintaining electrical isolation in compact assemblies.
AlN conducts heat through an electrically insulating body, helping spread concentrated heat from a device toward the cooling interface.
Product Features
- Thermal Management
- Electrical Insulation
- Precision Surface Options
- Drawing-Based Customization
Typical Applications
- Power Electronics — Power modules and insulated heat-spreading interfaces: Supports heat-transfer and electrical-isolation review in one component.
- Laser and Optoelectronics — Laser diode and optical module carriers: Supports compact thermal-path and mounting requirements.
