Effect of Silicon Carbide Addition on Soft Charge of High Alumina Silicon Carbide Brick

Effect of Silicon Carbide Addition on Soft Charge of High Alumina Silicon Carbide Brick

Adding too much will lead to an increase in the coefficient of thermal expansion, adding too little will lead to insufficient relative content of silicon carbide, adding the right amount of silicon carbide can improve the thermal shock resistance and wear resistance of high aluminum carbide bricks.

What is the aluminum silicon carbide substrate and the advantages and disadvantages of the aluminum silicon carbide substrate

What is the aluminum silicon carbide substrate and the advantages and disadvantages of the aluminum silicon carbide substrate

1. AlSiC has high thermal conductivity (170~200W/mK), which is ten times that of general packaging materials. It can dissipate the heat generated by the chip in time and improve the reliability and stability of the entire component 2. The thermal expansion coefficient of AlSiC is well matched with the semiconductor chip and the ceramic substrate, and the adjustable thermal expansion coefficient (6.5~9.5 × 10-6/K) can prevent fatigue failure, and even the power chip can be directly mounted on the AlSiC substrate.
