US Patent:

6773543, Aug 10, 2004

Filed:

May 6, 2003

Appl. No.:

10/430621

Inventors:

Michael A. Summers - Santa Cruz CA

Assignee:

Delaware Capital Formation, Inc. - Wilmington DE

International Classification:

B32B 3500

US Classification:

156344, 156584, 294263, 294266, 438464

Abstract:

A method for the co-processing of bare die removal from a semiconductor wafer for the improved throughput of the extraction of die from a wafer for subsequent placement onto a substrate. The apparatus includes a pick head containing a nozzle having a suction port within that secures the bare die as it is removed from the wafer. The intermediate holding station has a plurality of nozzles, each having a vacuum port to secure and buffer a multitude of flipped die that are transferred from the pick nozzle. Vacuum flow valves enable the release and transfer of the bare die. Having a multiple of nozzles provides a buffer for the die as they are subsequently transitioned from the pick nozzle, queued within the intermediate transfer station and loaded in tandem onto a die shuttle.

International Classification:

B65H001/00
B65H029/00

US Classification:

414/225010, 414/788000, 414/222010

Abstract:

The present invention is a method and apparatus for automatically storing and replenishing expandable wafers used in component feeders used in automated printed circuit board assembly systems, for example the Hover-Davis Direct Die Feeder (DDF). In the mass production of printed circuit boards automated pick-and-place equipment accepts die from “chip feeders” and then mounts them at a predetermined location on the circuit board. The present invention includes a wafer or tape reel storage bay and a gripping assembly that is moved by a gantry robot to retrieve a wafer or reel from the storage bay and automatically deposit it into a component feeder.

International Classification:

G01N 33/487
C12Q 1/6869
G01N 27/447

Abstract:

Two-pore devices and method for sequencing are described. A two-pore device can include first chamber, a second chamber, and a third chamber, wherein the first chamber is in communication with the second chamber through a first nanopore, and wherein the second chamber is in communication with the third chamber through a second nanopore. The device can also include sensing circuitry for measuring electrical signals associated with a target at a nanopore, and a control circuitry for controlling motion of the target at a nanopore. The device can include and/or switch between sensing and control modes for each of the first nanopore and the second nanopore. Sequencing methods can implement a two-pore device in relation to translocation of a target through one or more nanopores, switching between sensing and control modes as appropriate, and measuring aspects of the target using in sensing modes.

Abstract:

An ultrasonic system operable at high drive frequencies and/or in pulsed operation is disclosed. The system may be used in a procedure to treat an occluded blood vessel. The system can be used to transmit ultrasonic energy from an ultrasonic transducer to a distal end of an ultrasonic transmission device. The ultrasonic device may operate at a resonant frequency. The resonant frequency can be determined prior to using the device and/or during use. The ultrasonic device may operate in a range of frequencies at or near resonance. Operational parameters including, for example, reflected vibrations, temperature, and/or user input can be used by the system to adjust the driving waveform.
