  • Free piston stirling cooler temperature control system for semiconductor test
    Patent number: 10126359
    Abstract: A portable cooling system and apparatus for semiconductor device testing includes a free piston Stirling cooler. This eliminates the need for cumbersome remotely located equipment, such as a chillers, compressors, coolant storage equipment, hoses and hose connections. An electrical power line and an air supply line are routed from a head control unit to a portable system control unit. The head control unit is positioned by an adjustable frame structure to locate the Stirling cooler vertically directly over a semiconductor device under test. The head control unit includes a thermal adapter system, which is configured between the free piston Stirling cooler and the semiconductor device under test.
