Insulation type Cu-AlN-Cu submounts – TECNISCO LTD.
This is a heat sink for high-power LD (Laser diode) modules.
Three-layer composition achieves both high thermal conductivity and insulation quality. Control of Cu plating thickness makes the heat sink match with the LD, resulting in higher power and longer life of the LD module. Because pullback is not required on the critical edge area, it has a high degree of freedom in designing. Moreover, it can be applied to a variety of application by this freedom in design.

Features
- AlN + Cu composite material to achieve higher thermal conductivity and insulation quality
- CTE (coefficient of thermal expansion) matching with the LD (Laser diode)
・Adjusting Cu and AlN thickness makes it possible to control CTE - Ideal for multi-emitting type LD
- Pullback is not required on the critical edge area
・Ideal for P side down type LD - AuSn/AuGe solder vapor deposition
- Easy alignment with LD on the sharp edge
・Edge radius less than 20 μm
