Thermal analysis software picks optimum heat sink design

Though seemingly simple, heat sinks are complex designs that balance at least eight variables to achieve optimum performance. This balancing act is especially important in designs for digital applications where shrinking packaging size makes it increasingly difficult to remove heat. For best results, the heat sink should be designed specifically to fit the application. An optimum design significantly lowers final product cost: increases reliability, and shortens product time-to-market. It can even enhance electrical performance, such as with computer chips where clock speed is related to junction temperature
