A square isothermal chip is of width w = 5 mm on a side and is mounted in a substrate such that its side and back surfaces are well insulated, while the front surface is exposed to the flow of a coolant at T= 15°C . From reliability considerations, the chip temperature must not exceed T = 85°C .
If the coolant is air and the corresponding convection coefficient is h = 200 W/m2K, what is the maximum allowable chip power?
If the coolant is a dielectric liquid for which h = 3000 W/m2K, what is the maximum allowable chip power?
