Asquare 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[infinity] = 15°c. from reliability considerations, the chip temperature must not exceed t = 85°c. f the coolant is air and the corresponding convection 200 w/m2 k, what is the maximum coefficient is h allowable chip power? if the coolant is a dielectric liquid for which h 3000 w/m2 k, what is the maxi- mum allowable power?
