    摘要: A plurality of through-substrate holes is formed in each of at least one substrate. Each through-substrate hole extends from a top surface of the at least one substrate to the bottom surface of the at least one substrate. The at least one substrate is held by a stationary chuck or a rotating chuck. Vacuum suction is provided to a set of through-substrate holes among the plurality of through-substrate holes through a vacuum manifold attached to the bottom surface of the at least one substrate. An injection mold solder head located above the top surface of the at least one substrate injects a solder material into the set of through-substrate holes to form a plurality of through-substrate solders that extend from the top surface to the bottom surface of the at least one substrate. The vacuum suction prevents formation of air bubbles or incomplete filling in the plurality of through-substrate holes.

    摘要: A system and method are provided for injection molding conductive bonding material into a plurality of cavities in a mold within a vacuum chamber. A mold and a fill head are located within a vacuum chamber, wherein the mold includes a plurality of cavities. A vacuum is created within the vacuum chamber, thereby removing air from the chamber and from the cavities. Optionally, rotational motion is provided to at least one of the mold and the fill head while the fill head is in substantial contact with the mold. Conductive bonding material is forced out of the fill head toward the mold, and into at least one of the cavities, while a vacuum is maintained in the vacuum chamber.

    摘要: An injection molded soldering head includes a substrate that is flexible (compliant) and stable at high temperature. The substrate includes an aperture therethrough for holding and dispensing solder onto a mold and a low friction coating on the bottom side of the substrate to provide a lower friction surface for the head.

    摘要: Probes are directly patterned on a test substrate, thereby eliminating a need for an interposer. Probe contact structures are formed as a two-level structure having a greater lateral dimension for a lower level portion than for an upper level portion. First cavities are formed in a masking layer applied to a test substrate, filling the cavities with a conductive material, and planarizing the top surfaces of the conductive material portions to form lower level portions. Another masking layer is applied over the lower level portions and patterned to define second cavities having a smaller lateral dimension that the lower level portions. The second cavities are filled with at least one conductive material to form upper level portions of the probe contact structures. The upper level portion of each probe contact structure can be employed to penetrate a surface oxide of solder balls.

    摘要: Briefly, a novel material process is disclosed wherein one or more nucleation modifiers are added, in trace amounts, to a lead-free tin-rich solder alloy to produce a solder composition with reduce or suppressed undercooling temperature characteristics. The modifier being a substance which facilitates the reduction of extreme anisotropic properties associated with body-centered-tetragonal tin based lead-free solder. The addition of the nucleation modifiers to the solder alloy does not materially effect the solder composition's melting point. As such, balls of solder with the nucleated composition freeze while other solder balls within the array remain in the melt. This effectively enables one substrate to be pinned to another substrate by one or more predetermined solder balls to secure the package while the remaining solder joints are in the liquid state. Further, the addition of a trace amount of nucleation sites within the composition facilitates control over the number, size, and orientations of primary intermetallic compounds in tin rich crystallite grains. Moreover, trace amounts of one or more solid and/or insoluble nucleating modifiers within a given volume of solder reduces the size of average crystallites within the composition.
