ABOUT Heat Spreaders: Heat spreaders are made from Aluminum mixed with Silicon-Carbide particles (AlSiC). This combination results in a low CTE composite that is able to dissipate heat generated by the die on ceramic CCGA packages. AlSiC have high thermal conductivity and low thermal expansion compatible with semiconductor silcon chips and ceramic substrates enabling higher performance to prevent fatigue failure. The AlSiC heat spreader is attached directly to the top of the power chip using a thermal interface material (TIM) such as SE 4450 Adhesive. The thermal conductivity rate of AlSiC permits chip heat to be distributed evenly with higher performance for reliability and stability. AlSiC-8 material composition is 37% volume of Al and 63% volume of SiC. The heat sink is plated with electroless nickel (Ni) 4~8 um (157~315 micro-inch) thickness.
