  • Publication number: 20070295530
    Abstract: An electrical component includes a conductive substrate, a tin layer formed on the substrate, and a conformal coating formed on the tin layer to impede tin whisker growth. The conformal coating includes a polymer matrix, and particles that are dispersed about the matrix. The particles are either significantly harder than the polymer matrix, or are significantly softer than the polymer matrix.

  • Publication number: 20070284700
    Abstract: An electrical component includes a conductive substrate, a tin layer formed on the substrate, and a conformal coating formed on the tin layer to impede tin whisker growth. The conformal coating comprises a polymer matrix having gas-filled voids dispersed therethrough. In a method for impeding tin whisker growth from a tin plating or finish formed over an electrical component, a gas is infused into a liquid polymer. The tin plating or finish is then covered with a conformal coating comprising the liquid polymer. Then, one or more of the temperature and pressure of the conformal coating are adjusted to thereby create a dispersion of gas-filled voids comprising the gas in the conformal coating.

  • Publication number: 20070287023
    Abstract: An electrical component includes a conductive substrate, a tin layer formed on the substrate, and a multi-phase coating formed on the tin layer to impede tin whisker growth. The multi-phase coating comprises a polymer matrix having pores dispersed therethrough, with the pores constituting at least 30% by volume of the coating. To form the multi-phase coating, the tin plating or finish is covered with a coating comprising a polymer matrix having a second material mixed therein. The second material is subsequently removed from the polymer matrix to produce a coating having pores in the matrix where the second material was disposed before being removed.

  • Publication number: 20070287022
    Abstract: An electrical component includes a conductive substrate, a tin layer formed on the substrate, and a coating of a foam formed on the tin layer to impede tin whisker growth, the coating comprising a foam having voids dispersed therethrough. A method for impeding tin whisker growth from a tin plating or finish formed over an electrical component includes covering the tin plating or finish with a coating of intumescent paint, and thereafter expanding the intumescent paint into a foam having voids dispersed therethrough.

  • Publication number: 20070013099
    Abstract: A method and apparatus are provided for forming embossed simulated boards through a combination of extrusion molding process and separate embossing step. During embossing, the extrudate from the extruder is pressure formed forming a texturized surface on at least one face of the board with the board being captured on all sides of the board during the embossing step. After embossing, the extrudate is cooled to a temperature sufficient to rigidify the thus cooled extrudate. The cooled extrudate may then be cut into the appropriate lengths.

  • Patent number: 7065449
    Abstract: A method and system for evaluating geophysical survey data is provided. Two neighboring flight paths of a geophysical survey are likely to have geophysical characteristics in common because neighboring flight paths cover geographic areas in a close proximity to one another. As such, neighboring flight paths will likely have similar geophysical characteristics and similar recorded data. Therefore, errors in data can be estimated by comparing data recorded from neighboring flight paths. If data from a flight path differs significantly from data recorded from a neighboring flight path, then the data from one or both flight paths may be corrupted and at least one of the survey lines may need to be repeated. This auto evaluate method allows field personnel to judge data close to real time to determine whether to repeat a flight path while still out in the field.

  • Publication number: 20060004519
    Abstract: A method and system for synchronizing geophysical survey data is provided. Detection of geophysically significant subsurface anomalies potentially associated with ore bodies or hydrocarbon deposits can be made by vehicle mounted surface or airborne regional gravitational studies. Recorded geophysical survey data is processed to synchronize data collected by various sensors. Data from the various sensors is synchronized based on position coordinates corresponding to locations where the data was collected. In this manner, at one specific location on Earth, the electromagnetic reading, magnetometer reading, gravimeter reading, and altimeter reading can all be associated together so that many characteristics of the specific location can be identified.
