摘要： A portion of compliant material includes four walls defining a slot. The slot has a relatively large cross-section end in fluid communication with a solder reservoir, and also has a relatively small cross-section end opposed to the relatively large cross-section end. The slot has a generally elongate rectangular shape when viewed in plan, with a length perpendicular to a scan direction, a width, parallel to the scan direction, associated with the relatively large cross section end, and a width, parallel to the scan direction, associated with the relatively small cross section end. The slot is configured in the portion of compliant material such that the relatively small cross-section end of the slot normally remains substantially closed, but locally opens sufficiently to dispense solder from the reservoir when under fluid pressure and locally unsupported by a workpiece. Methods of operation and fabrication are also disclosed.

摘要： A process for aligning at least two layers in an abutting relationship with each other comprises forming a plurality of sprocket openings in each of the layers for receiving a sprocket of diminishing diameters as the sprocket extends outwardly from a base, with the center axes of the sprocket openings in each layer being substantially alignable with one another, the diameter of the sprocket openings in an abutting layer for first receiving the sprocket being greater than the diameter of the sprocket openings in an abutted layer. This is followed by forming a plurality of reservoir openings in each of at least two of the layers and positioning the sprocket openings in the layers to correspond with one another and the reservoir openings in the layers to correspond with one another so that substantial alignment of the center axes of the corresponding sprocket openings in the layers effects substantial alignment of the center axes of the corresponding reservoir openings in the layers. Engaging the sprocket openings with the sprocket by inserting the end of the sprocket having the smallest diameter into the sprocket openings having the largest diameter in the layers and continuing through to the sprocket opening having the smallest diameter in the layers effects substantial alignment of the center axes of the corresponding sprocket openings and substantial alignment of the center axes of the corresponding reservoir openings in the layers. The invention also comprises apparatus for performing this process.

摘要： An interconnection structure suitable for flip-chip attachment of microelectronic device chips to packages, comprising a two, three or four layer ball-limiting metallurgy including an adhesion/reaction barrier layer, and having a solder wettable layer reactive with components of a tin-containing lead free solder, so that the solderable layer can be totally consumed during soldering, but a barrier layer remains after being placed in contact with the lead free solder during soldering. One or more lead-free solder balls is selectively situated on the solder wetting layer, the lead-free solder balls comprising tin as a predominant component and one or more alloying components.

摘要： A process is disclosed for producing a metal-organic polymer combination by contacting the polymer with a plasma followed by an aqueous solution of a metal salt. In one embodiment a water or nitrous oxide plasma is used to treat a polyimide or a fluorinated polymer. The polymer is combined with a metal cation, the metal being a catalyst for a conventional electroless coating after which it is contacted with an electroless metal plating bath for the formation of electrical circuits and especially for plating high aspect ratio vias in microcircuits. Unlike the conventional electroless process, the cationic catalytic metal is not reduced to a zero valent metal catalyst prior to the application of the electroless metal coating solution.The process also improves the wettability of the polymer, especially the fluorinated polymer and is especially useful in improving the wettability of high aspect ratio vias.
