  • Patent number: 11963307
    Abstract: A ball-grid-array component of a ball-grid array assembly is analyzed prior to reflow. A predicted warping pattern of the ball-grid-array component that is likely to occur during reflow is predicted based on the analyzing. A solder ball ball-grid-array defect that could be caused by the predicted warping pattern is predicted. An initial via suction pattern to mitigate the ball-grid-array defect is assigned. A vacuum head is applied to a via in the ball-grid-array assembly. The solder ball is located at the opposite end of the via from the vacuum head. Suction is applied to the via based on the via suction pattern. The suction draws a portion of the solder ball into the via during reflow.

  • Patent number: 11948807
    Abstract: A set of features for a product is identified. It is determined that preventing an electrical connection at a ball-grid-array location on a ball-grid-array assembly of the product would result in the set of features. The ball-grid-array location is established as a target BGA location based on that determination. Suction is applied to a via at the target BGA location during reflow of the ball-grid-array assembly. With that application of suction, a solder ball at the target BGA location is drawn into the via.

  • Publication number: 20240097292
    Abstract: A voltage source watchdog comprising a passive device is placed in series between a voltage source and a load. The passive device includes an electromigration (EM) joint of known materials that will create an electromigration void after a specified amount of current passes through the EM joint. After a known amount of current as passed through, a void is created and a voltage will no longer be sensed, thus providing a sure safety mode situation. When the voltage source is a battery, the battery life may be extended by selectively enabling voltage measurement operations for the proposed watchdog.

  • Patent number: 11809155
    Abstract: A manufacturing control system for an additive, subtractive, or hybrid machining system implements a morphic manufacturing approach that integrates in situ inspection and related decision-making into the manufacturing process. After execution of a machining or deposition operation, the system performs a sensor scan to collect sensor measurement data for the resulting part while the part remains in the manufacturing work cell. The measurement data is compared with an as-designed digital model of the part to determine whether further machining or deposition is necessary to bring the finished part into tolerance with the model. If necessary, the system performs another additive and/or subtractive manufacturing operation on the part based on analysis of the measurement data to bring the part into tolerance. The measured inspection data can be stored in association with each manufactured part for auditing purposes or for creation of part-specific digital twins.

  • Publication number: 20230288920
    Abstract: A manufacturing control system for an additive, subtractive, or hybrid machining system implements in situ part inspection to collect as-built metrology data for a manufactured part while the part remains in the work envelop, and uses the resulting measured inspection data to generate an as-built digital twin that accurately models the finished part. After execution of a subtractive and/or additive tooling operation, the system performs a sensor scan to collect three-dimensional imaging measurement data for the resulting manufactured part while the part remains in the work cell. The measurement data is then integrated with as-designed part metadata for the idealized part to yield the as-built digital twin. Since metrology measurements are integrated into the manufacturing process, customized as-built digital twins can be generated for each manufactured part without requiring manual inspections to be performed on each part.

  • Publication number: 20230170641
    Abstract: An approach for connecting electrical wiring between two chambers of varying temperatures is disclosed. One approach includes a first end of a wiring bundle comprising a first plurality of metal conductors; a second end of the wiring bundle comprising of equal number of metal conductors as the first end of the wiring bundle; the first end of the wiring bundle is separated by an air gap from the second end of the wiring bundle at a first temperature; and an insulator surrounding the wire bundle. Another approach includes the use of one or more SMA (shape-memory alloy) pins connecting the first end of the wiring bundle to the second end of the wiring bundle and that is separated by an air gap and a boundary plate.

  • Publication number: 20230105433
    Abstract: Electrical current flow in a ball grid array (BGA) package can be measured by an apparatus including an integrated circuit (IC) electrically connected to the BGA package. Solder balls connect the BGA package to a printed circuit board (PCB) and are arranged to provide a contiguous channel for a current sense wire. A subset of solder balls is electrically connected to supply current from the PCB through the BGA package to the IC. The current sense wire is attached to the upper surface of the PCB, within the contiguous channel, and surrounds the subset of solder balls. An amplifier is electrically connected to the current sense wire ends to amplify a voltage induced on the current sense wire by current flow into the BGA package. A sensing analog-to-digital converter (ADC) is electrically connected to convert a voltage at the output of the amplifier into digital output signals.

  • Publication number: 20230052436
    Abstract: A system and method for slowing a vehicle. Road conditions around the vehicle are monitored, and determined if those road conditions are hazardous. An engine control unit is informed of the hazardous road conditions and alters the operation of the engine control unit in response to the hazardous road conditions. When an operator of the vehicle desires to slow the vehicle down, an indication is received indicating the intent to slow the vehicle down. The vehicle is then slowed based upon the altered operation of the engine control unit by applying a vacuum to increase a manifold vacuum of the engine.

  • Patent number: 11538638
    Abstract: A grid array capacitor can be used to physically and electrically couple an integrated circuit (IC) package to a printed circuit board (PCB). The grid array capacitor includes an inner conductor and an inner dielectric coaxially surrounding the inner conductor. A secondary conductor can be located to surround, in a coaxial orientation, the inner dielectric. Both the inner conductor and the secondary conductor can be electrically connected to the IC package and to the PCB. In certain applications, the structure of the inner conductor, inner dielectric, and secondary conductor can provide capacitance used to decouple electronic circuits.

  • Patent number: 11488571
    Abstract: A system and method to prevent eavesdropping by a device. An anti-eavesdrop component is installed on the device. The anti-eavesdrop component is configured to actively prevent the device from capturing audio from the environment. In response to installing the anti-eavesdrop component, the device recognizes the anti-eavesdrop component as a primary audio input for the device. The anti-eavesdrop component then proceeds to block the device from capturing outside audio by injecting noise or otherwise interfering with the primary audio input.
