    Abstract: An electronics module is assembled by demountably attaching integrated circuits to a module substrate. The module is then tested at a particular operating speed. If the module fails to operate correctly at the tested speed, the integrated circuit or circuits that caused the failure are removed and replaced with new integrated circuits, and the module is retested. Once it is determined that the module operates correctly at the tested speed, the module may be rated to operate at the tested speed and sold, or the module may be tested at a higher speed.

    Abstract: An interconnect assembly and methods for making and using the assembly. An exemplary embodiment of an aspect of the invention includes a contact element which includes a base portion adapted to be adhered to a substrate and a beam portion connected to and extending from the base portion. The beam portion is designed to have a geometry which substantially optimizes stress across the beam portion when deflected (e.g. it is triangular in shape) and is adapted to be freestanding. An exemplary embodiment of another aspect of the invention involves a method for forming a contact element. This method includes forming a base portion to adhere to a substrate of an electrical assembly and forming a beam portion connected to the base portion. The beam portion extends from the base portion and is designed to have a geometry which substantially evenly distributes stress across the beam portion when deflected and is adapted to be freestanding. It will be appreciated that in certain embodiments of the invention, a plurality of contact elements are used together to create an interconnect assembly. Various other assemblies and methods are also described below in conjunction with the following figures.

    Abstract: A main power source supplies current through path impedance to a power terminal of an integrated circuit device under test (DUT). The DUT's demand for current at the power input terminal temporarily increases following edges of a clock signal applied to the DUT during a test as transistors within the IC switch in response to the clock signal edges. To limit variation (noise) in voltage at the power input terminal, an auxiliary power supply supplies an additional current pulse to the power input terminal to meet the increased demand during each cycle of the clock signal. The magnitude of the current pulse is a function of a predicted increase in current demand during that clock cycle, and of the magnitude of an adaption signal controlled by a feedback circuit provided to limit variation in voltage developed at the DUT's power input terminal.
