Abstract
Abstract A means and method for cooling enhancement of microelectric devices tested at high power levels in a liquid bath by gas jet impingement, the means including a substrate means for positioning a microelectric device within a liquid cooling bath and means for supplying testing power from a power source to the microelectric devices, and a gas jet means for impinging a gaseous flow upon the microelectric device while positioned on said substrate means. The method includes securing the microelectric devices upon the substrate means, which is in turn submersed in the liquid coolant bath. a gas jet is impinged upon the microelectric devices and testing power supplied thereto.
