  • Publication number: 20210146365
    Abstract: Techniques include a substrate having a microchannel, first and second microchannel branches, and a fork joining the microchannel upstream and the branches downstream. The microchannel passes a continuous stream of droplets, having a first fluid with magnetic particles, separated by a spacer fluid. A picoinjector, disposed along the microchannel, includes both: a supply channel connected to the microchannel by an aperture on a first side of the microchannel; and, a pair of electrodes on an opposite side. The picoinjector injects a volume of a second fluid into a first droplet when the pair of electrodes carries a certain voltage difference. A first magnet introduces a magnetic field into the microchannel between the picoinjector and the fork to move magnetic particles in the first droplet toward the first side of the microchannel before the droplet is split at the fork to produce output droplets of the second fluid with magnetic particles.

  • Patent number: 6995026
    Abstract: A method and apparatus for supporting a microelectronic substrate. The apparatus can include a microelectronic substrate and a support member carrying the microelectronic substrate. The apparatus can further include a first connection structure carried by the support member. The first connection structure can have a first bond site configured to receive a flowable conductive material, and can further have at least two first elongated members connected and extending outwardly from the first bond site. Each first elongated member can be configured to receive at least a portion of the flowable conductive material from the first bond site, with none of the first elongated members being electrically coupled to the microelectronic substrate. The assembly can further include a second connection structure that is electrically coupled to the microelectronic substrate and that can include second elongated members extending away from a second bond site.

  • Publication number: 20050087337
    Abstract: An apparatus and method for forming or repairing a wellbore casing, a pipeline, or a structural support. An expandable tubular member is radially expanded and plastically deformed by an expansion cone that is displaced by hydraulic pressure. Before or after the radial expansion of the expandable tubular member, a sliding sleeve valve within the apparatus permit a hardenable fluidic sealing material to be injected into an annulus between the expandable tubular member and a preexisting structure.

  • Publication number: 20050029554
    Abstract: A BGA and a system implementing a BGA. Specifically, a BGA package is encapsulated after the balls are attached to the package. The backside of the package having the balls disposed thereon may be completely covered by the encapsulant. The encapsulant is disposed in direct contact about a portion of the balls. A liner is provided to facilitate the formation of an unencapsulated portion of each ball. The unencapsulated portion may be used to couple the package to a system.
