Thermal Interface Materials come in many types, options, and thermal conductivities. Because of this, Boyd Genie simplifies the user input for thermal interface material (TIM) as interface resistance. Boyd Genie also allows you to define the TIM for each heat source. Since the Genie supports up to 10 individual heat sources, it means you have up to 10 different inputs for interface resistance. When a heat source is selected in the positioning diagram graphic user interface (GUI), the heat source should highlight in yellow. You should also see the geometric dimensions on the right above the heat source GUI update to the heat source you’ve selected.
On the side of the GUI, the heat source section for that selected source will also update with the dimensions and other specifications applied to this heat source. On the bottom of this section, Boyd Genie has an input to account for interface resistance from using a thermal interface material on that source. If you need help determining what TIM you need or what your interface resistance is, please contact Boyd Design Engineers.
