Although various embodiments of the method and apparatus of the present invention have been illustrated in the accompanying Drawings and described in the foregoing Detailed Description, it will be understood that the invention is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the spirit of the invention as set forth herein.

Self contained, liquid to air cooled, memory test engineering workstation

A fixture assembly is presented. The fixture assembly includes a device interface assembly for mating with a device under test and a tester interface assembly for mating with the device interface assembly on one side and a tester on a second side. In the method and apparatus of the present invention, the device interface assembly includes a probe field specific to a device under test and may be changed to accommodate a different device, without changing the tester interface assembly. The tester interface assembly includes a custom electronic module and a standardized electronic module, which are both coupled to a PCB interface in the tester interface assembly. As such, both standardized and specialized test may be modified and changed without redesigning the tester interface assembly.

Adapter method and apparatus for interfacing a tester with a device under test

A fixture assembly is presented. The fixture assembly includes a device assembly for mating with a device under test and a tester interface assembly for mating with the device assembly on one side and a tester on a second side. In the method and apparatus of the present invention, the device assembly includes a probe field specific to a device under test and may be changed to accommodate a different device, without changing the tester interface assembly. The tester interface assembly includes a frame used for alignment and structural support. The frame interfaces with a probe plate on one side and a load plate on the other side. The probe plate holds a plurality of probes in place while the load plate provides a plurality of holes for the probes to extend downward through the load plate. A printed circuit board (PCB) is positioned below the load plate and makes contact with the ends of the probes. The entire tester interface assembly is positioned on top of an electronic tester and maps points of contact in the tester with the probe field of the device assembly.
