Abstract
A heat spreader includes a plurality of sensors that indicate that the heat spreader is flat against and in thermal contact with a plurality of chips when the heat spreader is loaded upon a chip stack. One or more nodes within the sensors are connected by electric conductors. The resistances of the conductors may be compared to determine if the nodes within the sensors are relatively flat. Sensor flatness may be indicated to a higher level electronic device such as a visual display. The display may ultimately be viewed by a user to determine whether the heat spreader is flat and in thermal contact with the plurality of chips when the heat spreader is loaded upon the chip stack.
