Advantages:
- Low thermal resistance.
- Excellent insulation properties
- Reduce solder layers, lower thermal resistance, reduce cavities, increase the rate of finished products.
- The super-thin 0.25mm DBC substrate can be substituted for BeO eliminating the problems of environmental pretection and toxicity.
- Avoid withstand the stress caused by the impact of temperature changes, thus greatly extend the life of semiconductor products.
- The new packaging and assembly methods can be realized with DBC substrates, it makes the products a higher degrees of integration and volume reduction.
- The thermal expansion coefficient close to silicon in the semiconductor chip, it can directly solder on the DBC substrate, saving the interface layer Mo plate and then decrease the cost.
