The Al diamond composite consists of an Aluminium matrix which contains finely dispersed diamond particles. The light-weight compound material exhibits enhanced thermal conductivity and the thermal expansion is adapted to commonly used semiconductor materials.
Advantages of Al diamond composites:
- Excellent thermal conductivity (440-530 W/mK at 20°C)
- Low coefficient of thermal expansion (7.0-9.0 ppm/K at 20°C)
- Well adapted to semiconductors and ceramics
Typical thermal management applications of Al diamond composites:
- Base plates for power electronic modules (e.g. IGBT)
- Heat sinks and base plates in the power, micro and optoelectronics
