  • Patent number: 6139661
    Abstract: A method for temporarily attaching an electrical component to a pad, testing the component, removing and replacing the component if necessary, and making a final attachment of the component to the pad. The method provides for attachment and removal of components, to and from pads located on the substrate of a printed circuit board, wherein the method enables components to be easily removed prior to final assembly without damaging the circuit board or components mounted thereon. The method utilizes a layer of conductive, radiation-curable adhesive placed between the component's lead and the pad. Radiation is then directed through a mask onto a portion of the adhesive layer, which cures the portion while leaving a remaining area of the adhesive layer uncured. Because the portion of the adhesive layer that receives the radiation, and is consequently cured by the radiation, is only a limited portion of the whole adhesive layer, the component may be easily removed from the pad by applying a small mechanical force.

  • Patent number: 6027593
    Abstract: The present invention relates to a rapid and low cost procedure for joining webs and films containing dissimilar polymers. It is especially applicable but not limited to the construction and assembly of disposable products such as infant and adult incontinent products, feminine hygiene products, and other low-cost, high volume disposable products. The process involves producing a high rate of heat flux through the dissimilar materials where the material with the higher plastic point is at the influx point and the lower plastic point material is adjacent and further from the heat source. In addition to this constraint and as a necessary component the application of the high rate of heat flux must be accompanied by a pressure of appropriate to the difference in plastic points and to the relative thickness of the dissimilar materials to be joined.
