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： Multiple injections of molten solder are employed to form double solder bumps having outer layers that melt at lower temperatures than the inner portions thereof. During a flip chip assembly process, the reflow temperature is above the melting temperature of the outer layers and below the melting temperature of the inner portions of the solder bumps. As the inner portions of the solder bumps do not collapse during reflow, a flip chip assembly can be made at relatively low temperatures and have a high stand-off height. A structure having double solder bumps facilitates flip chip assembly.

摘要： Solder bumps are provided on round wafers through the use of injection molded solder. Copper pillars or ball limiting metallurgy are formed over I/O pads within the channels of a patterned mask layer. Solder is injected over the pillars or BLM, filling the channels. Molten solder can be injected in cavities formed in round wafers without leakage using a carrier assembly that accommodates wafers that have been previously subjected to mask layer deposition and patterning. One such carrier assembly includes an elastomeric body portion having a round recess, the walls of the recess forming a tight seal with the round wafer. Other carrier assemblies employ adhesives applied around the peripheral edges of the wafers to ensure sealing between the carrier assemblies and wafers.

摘要： A flexible unitary mask has a plurality of through holes. A substrate has a plurality of wettable pads in recessed regions defining volumes. The through holes are aligned with the wettable pads. Molten solder is directly injected through the through holes of the flexible unitary mask into the volumes with the wettable pads, such that the through holes and the volumes with the wettable pads are filled with solder. The solder is allowed to solidify, forming a plurality of solder structures adhered to the wettable pads. The flexible unitary mask is peeled from the substrate after the solder has solidified.

摘要： An assembly is obtained; it includes a substrate; a plurality of wet-able pads formed on a surface of the substrate; and a solder resist layer deposited on the surface of the substrate and having an outer surface. At least the solder resist layer is formed with recessed regions defining volumes adjacent the wet-able pads. Molten solder is directly injected into the volumes adjacent the wet-able pads, such that the volumes adjacent the wet-able pads are filled with solder. The solder is allowed to solidify. It forms a plurality of solder structures adhered to the wet-able pads. The substrate and the solder are re-heated after the solidification, to re-flow the solder into generally spherical balls extending above the outer surface of the solder resist layer. The volumes adjacent the wet-able pads are configured and dimensioned to receive sufficient solder in the injecting step such that the generally spherical balls extend above the outer surface of the solder resist layer as a result of the re-heating step. In an alternative approach, solder injection and solidification are carried out in a nitrogen environment or a forming gas environment, and the reflow step may be omitted.
