Abstract: An apparatus for thermal control of a device under test (DUT) includes a cooling structure operable to provide cooling, the cooling structure operable to inlet cooling material via an inlet port thereof and operable to outlet. cooling material via an outlet port thereof, a variable thermal conductance material (VTCM) layer disposed on a surface of the cooling structure, and a heater layer operable to generate heat based on an electronic control, and wherein the VTCM layer is operable to transfer cooling from the cooling structure to the heater layer. A thermal interface material layer is disposed on the heater layer. The thermal interface material layer is operable to provide thermal coupling and mechanical compliance with respect to the DUT. The apparatus includes a compression a a mechanism for providing compression to the VTCM layer to vary a thermal conductance of the VTCM layer. The compression mechanism is also for decoupling the VTCM layer from the heater layer.

Abstract: A high volume system level testing of devices with POP structures such as POP memories includes a POP array that includes floating nests that can adjust in the XY direction in order to align individually with respective pads found on the DUTs. The floating nests also include a mechanically fixed PCB that is fixed to the nest and can either mate to a memory contactor array that can accept an unattached POP device such as a memory or can include an attached memory in order to accommodate different POP requirements. In a method, the POP array includes a number of floating nests with memory loaded are aligned and presented to their respective DUTs just prior to testing the combined DUT and POP memory assemblies.

Abstract: A robotically assisted flexible test and inspection system that is portable and adaptable to test and/or inspect products is described. The test and inspection system is a compact system that can be moved easily to different locations and includes a robotic arm which is used for testing and inspection of a unit-under-test (UUT). The robotic arm can be used to activate different controls in the UUT or cause different functionality of the UUT to be tested. The robotic arm can use different tools such as a switch activator tool, to accomplish its tasks. The test and inspection system in one embodiment is a movable test cart, wherein the robotic arm is located in one of the shelves of the test rack and the UUT is located in another shelf of the test rack which has an aperture that presents portions of the UUT to the robotic arm. Another shelf or shelves of the moveable test rack can accommodate a test system controller, testing and inspection components/instruments, etc.
