The chip and substrate are each 10 mm on a side, and their exposed surfaces are cooled by air, which is at a temperature of 25 C and provides a convection heat transfer coefficient of 100 W/m K. if the chip dissipates 10* W/ m? under normal operating conditions, will it operate below a maximum allowable temperature of 85 C For aluminum k = 239 W/m K, for epoxy k = 0.22 W/m K T- 25C h = 100 W/m2-K Air Insulation Silicon chip oint (0.02 mm) L=8 mm Aluminum- substrate T= 25C h = 100 W/m2-K Air
