  • Publication number: 20080025813
    Abstract: An assembly for mounting electronic components includes a face plate comprising a thermoplastic material. The face plate includes a retaining element for securing a captive screw and spring assembly for mounting an electronic printed circuit board. The retaining element includes one or more slots adapted to expand the element to permit insertion of the screw and deformation of the hole upon insertion of the screw, while locking the screw to retain the screw in place. This arrangement permits the elimination of the metal standoff frequently used in similar devices. Methods for preparing the assembly and mounting the printed circuit boards are also described.

  • Publication number: 20080020565
    Abstract: A method for creating a dual damascene structure while using only one lithography and masking step. Conventional dual damascene structures utilize two lithography steps: one to mask and expose the via, and a second step to mask and expose the trench interconnection. The novel method for creating a dual damascene structure allows for a smaller number of processing steps, thus reducing the processing time needed to complete the dual damascene structure. In addition, a lower number of masks may be needed. The exemplary mask or reticle used within the process incorporates different regions possessing different transmission rates. During the exposing step, light from an exposing source passes through the mask to expose a portion of the photoresist layer on top of the wafer.

  • Publication number: 20050249332
    Abstract: A test set includes at least one signal input port, a test circuitry, a processor, a user-input device, and a display. The test circuitry couples to and receives signals from the at least one signal input port. The test circuitry then generates test data corresponding to the received signals. The processor couples to and receives test data from the test circuitry and generates test results. The processor also couples to and receives commands from the user-input device. The processor further operatively couples to the graphical display that receives and displays the test results from the processor. In one embodiment, the test set is capable of performing line qualification and connectivity testing. A modem module can be used to facilitate connectivity testing. The modem module can be a plug-in module with a common interface to the test set.
