摘要： A computing system includes an automatic optical inspection (AOI) and a database that stores images of a plurality of visual inspection (VI) training boards. Each of the visual inspection (VI) training boards includes at least one intended defect. The AOI system includes an artificial intelligence (AI) algorithm implemented in an automatic optical inspection (AOI) system. The AOI system trains the AI algorithm to learn at least one target defect based on the at least one intended defect including in the plurality of VI training boards, analyzes a production printed circuit board (PCB), and determines either a non-defective PCB in response to the AI algorithm determining the production PCB excludes the at least one target defect, or a defective PCB in response to the AI algorithm determining the production PCB includes at least one target defect.

摘要： System and methods for solder void analysis with an optical inspection component are described, including a plurality of optical fibers longitudinally disposed through a glass tube such that ends of the optical fibers are exposed from corresponding ends of the glass tube. A solderable fill encompassing each of the optical fibers by filling spaces between each of the optical fibers and between the optical fibers and the glass tube such that the ends of the glass tube include the ends of the optical fibers surrounded by the solderable fill to form an interface around the optical fibers for soldering one of the ends of the glass tube to a solder pad.

摘要： A method for cleaving a fiber comprises rotating an actuator to apply a positioning force to a blade in a scoring assembly. The positioning force produces a score in the surface of a fiber, and the method further comprise applying a cleaving force to the fiber to cleave the fiber. The method can further include measuring the magnitude of the positioning force and rotating the actuator until the magnitude corresponds to a pre-determined magnitude. A cleaver comprises a scoring assembly, drive assembly, and a cleaving assembly. The scoring assembly includes a holder having one or more blades, and an actuator. The cleaving assembly secures a fiber in the scoring assembly. The drive assembly rotates the actuator to position one or more blades to score the surface of the fiber. The cleaving assembly applies a cleaving force to the fiber to cleave the fiber at the location of the score.

摘要： Embodiments of the present invention provide a computer-implemented method for identifying a specified object. The method includes collecting attributes of a physical object within a physical space, in which the attributes include an object temperature obtained via an (IR) sensor and an object shape obtained via an image sensor. A machine learning algorithm is executed to allocate a coordinate to the object based on the attributes. In response to a request from a user to locate the object, the physical space is scanned via the IR sensor and the image sensor to identify the object and to detect a present location. An indication of a location of the object is then displayed to the user, in which the indication is at least one of the present location of the object or a predicted location of the object.
