Abstract
A heating and cooling apparatus is provided which employs a series of thermally conductive plates thermally coupled to heating and cooling devices to heat or cool a mounting plate loaded with semiconductor devices. The mounting plate is assembled on a heating plate, which is then assembled on a cooling plate. The heating plate includes upper and lower plates with a heater therebetween which can heat the heating plate to a desired temperature, which in turn heats the mounting plate and the semiconductor devices. The cooling plate has 'S' shaped flow grooves formed throughout. When cooling fluid is flowed through the flow grooves, the cooling plate is cooled, which cools the heating plate, which in turn cools the mounting plate and the semiconductor devices.
