What is Thermal Management? – AlSiC is Thermal Management!

Integrated heat spreader flip chip lids require materials that have good thermal conductivity and a compatible thermal expansion for thermal management. Thermal management also requires shape capability and stiffness to maintain a thin TIM1 bond line during product life. A stiff material lid can control warping and bowing during assembly to improve solder attachment and reduces warping during cycling to maintain a thin TIM1 bond line for the best thermal dissipation and device performance. Lightweight lid materials provide an advantage by reducing weight per solder ball and orientation dependence. In addition light weight materials enable larger lids to be considered for improved thermal dissipation schemes. AlSiC flip chip lids provide all of these attributes!
