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; the front surface is exposed to the flow of a coolant at T = 15C. From reliability considerations, the chip temperature must not exceed T 85C. Coolant 88 Too, h Chip W If the coolant is air and the corresponding convection coefficient is h = 200 W/m K, what is the maximum allowable chip power? If the coolant is a dielectric liq- uid for which h=3000 W/m K, what is the maximum allowable power?
