Apparatuses and methods are described herein for processing polynucleotides in a sealed path environment. The apparatuses include optical sensors to monitor operations and to track material usage for good manufacturing practice.

Microfluidic apparatus and methods of use thereof

Filling systems and related container assemblies and methods are disclosed. In an implementation, a container assembly includes a container array, covers, a framework, and a fluidic network. The container array includes containers having distal ends and the covers are coupled to the respective distal ends of the containers. The framework is integral with: 1) the containers, 2) the covers and couples the containers together, or 3) both. The fluidic network includes fluidic channels that are defined by the framework and enable the containers to be filled in series or in parallel.

Filling systems and related container assemblies and methods

The application relates to microfluidic apparatus and methods of use thereof. Provided in one example is a microfluidic device comprising: a first fluidic input and a second fluidic input; and a fluidic intersection channel to receive fluid from the first fluidic input and the second fluidic input, wherein the fluidic intersection channel opens into a first mixing chamber on an upper region of a first side of the first mixing chamber, wherein the first mixing chamber has a length, a width, and a depth, wherein the depth is greater than about 1.5 times a depth of the fluidic intersection channel; an outlet channel on an upper region of a second side of the first mixing chamber, wherein the outlet channel has a depth that is less than the depth of the first mixing chamber, and wherein an opening of the outlet channel is offset along a width of the second side of the first mixing chamber relative to the fluidic intersection.

Improved electrically conductive guide plates for vertical probe arrays are provided by patterning a thin metal layer disposed on an insulating substrate. Holes passing through the guide plate for guiding probes can be electrically connected or isolated from each other in any pattern according to the deposition of the metal. Such structures can include several distinct ground and/or voltage planes. Furthermore, passive electrical components can be included in the guide plate, by patterning of the deposited metal and/or by integration of passive electrical components with the deposited metal traces.

Direct metalized guide plate

Crosstalk between probes in a vertical probe array is reduced by providing a grounded metal carrier disposed between the guide plates of the probe array. The metal carrier includes pockets that are laterally separated from each other by the metal carrier. Probes in different pockets are thereby electrically shielded from each other.

Shielding for vertical probe heads

Vertical probe heads having a space transformer laterally tiled into several sections are provided. This change relative to conventional approaches improves manufacturing yield. These probe heads can include metal ground planes, and in embodiments where the ground planes are provided as separate metal plates parallel to the guide plates, the metal plates can also be laterally tiled into several sections. Such tiling of metal plates improves manufacturing yield and alleviates thermal mismatch issues. Probes are not mechanically connected to the space transformer, which facilitates replacement of individual probes of an array.

Vertical probe array having a tiled membrane space transformer

Improved impedance matching is provided in vertical probe arrays having conductive guide plates by providing ground pins connecting the guide plates that do not mechanically touch the device under test or the input test apparatus. Such ground pins can be disposed in predetermined patterns around corresponding signal probes to improve an impedance match between the probes and the test apparatus and/or the device under test. Preferably all impedances are matched to 50&#x3a9; as is customary for high frequency work.

Probe head with inductance reducing structure

Electrically conductive columns of intertwined carbon nanotubes embedded in a mass of material flexible, resilient electrically insulating material can be used as electrically conductive contact probes. The columns can extend between opposing sides of the mass of material. Terminals of a wiring substrate can extend into the columns and be electrically connected to an electrical interface to a tester that controls testing of a device under test. A pair of physically interlocked structures can coupling the mass of material to the wiring substrate. The pair can include a receptacle and a protrusion.

A multiple conduction path probe can provide an electrically conductive signal path from a first contact end to a second contact end. The probe can also include an electrically conductive secondary path and an electrically insulated gap between the signal path and the secondary path. A probe assembly can comprise multiple such probes disposed in passages in substantially parallel electrically conductive guide plates. In some configurations, the probe assembly can include one or more secondary probes disposed in passages of the conductive guide plates and electrically connected to one or both of the guide plates. Some of the probes can be electrically insulated from the guide plates and thus provide signal paths, and others of the probes can be electrically connected to the guide plates and thus provide secondary paths.

Multipath electrical probe and probe assemblies with signal paths through secondary paths between electrically conductive guide plates

A test socket for facilitating testing of a device under test (DUT) includes a holder comprising a mounting structure for attaching the holder to other components of the socket and a floating nest structure in which the DUT can be disposed. The floating nest structure can have a seat cavity sized and shaped to receive and hold the DUT such that at least some of the DUT terminals are in contact with corresponding contacts of a test board while the test socket is attached to the test board. A flexure located laterally between the mounting structure and the floating nest structure and can allow the nest structure to move relative to the mounting structure and thus float.
