摘要: A bonding system for bonding a semiconductor element to a substrate is provided. The bonding system includes a substrate oxide reduction chamber configured to receive a substrate. The substrate includes a plurality of first electrically conductive structures. The substrate oxide reduction chamber is configured to receive a reducing gas to contact each of the plurality of first electrically conductive structures. The bonding system also includes a substrate oxide prevention chamber for receiving the substrate after the reducing gas contacts the plurality of first electrically conductive structures. The substrate oxide prevention chamber has an inert environment when receiving the substrate. The bonding system also includes a reducing gas delivery system for providing a reducing gas environment during bonding of a semiconductor element to the substrate.

摘要: A pipe processing tool that is configured to deform the end of a pipe so that the circumferential shape of the end of the pipe generally matches the circumferential shape of an adjacent pipe end. Matching the circumferential shapes of the pipe ends is advantageous during a pipe attachment process. The pipe processing tool can include a deformation ring with a plurality of pipe deformation members. Each pipe deformation member faces radially inward and is actuatable in a radial direction toward and away from the center of the deformation ring in order to permit engagement with the pipe. Each pipe deformation member is individually and separately actuatable from the other pipe deformation members so that the circumferential shapes of the pipes can be altered by controlling suitable ones of the pipe deformation members.

摘要: Gerber data for a substrate includes coordinates for physical features on the substrate. The coordinates are relative to a substrate origin point on the substrate. The gerber data allows a user to specify any of the physical features as soldering targets of a soldering apparatus that includes a motor for moving a soldering iron according to coordinates relative to a system origin point of the soldering apparatus. When the substrate is placed on the soldering apparatus, its substrate origin point differs from the system origin point of the soldering apparatus. The user may input coordinates for the substrate origin point, which are used by the soldering apparatus to derive coordinates, usable by soldering apparatus, from coordinates in the gerber data. In this way, it is possible to reduce the workload of the user when programming the soldering apparatus to perform a soldering process.

摘要: The invention relates to a method for repairing a damaged blade tip of a turbine blade which is armor-plated and provided with a blade coating, of a thermal gas turbine. The method according to the invention comprises the steps of removing a blade tip armor plating of the turbine blade at least in the region of the damaged blade tip and producing a repair surface (12), removing only a part of the blade coating of the turbine blade in the region of the repair surface while preserving a part of the blade coating separated from the repair surface (14), restoring the blade tip reinforcement (20), and restoring the blade coating in the region of the repaired blade tip (22). The invention furthermore relates to a device for carrying out such a method.

摘要: A bead appearance inspection device includes an acquisition unit that acquires input data related to a welding bead, a storage unit that stores a first determination standard and a second determination standard used for an inspection of a defect of the welding bead, a first determination unit that executes a first inspection determination on the welding bead, and k second determination units, where k is an integer of 1 or more, that execute a second inspection determination on the welding bead. An appearance inspection result of the welding bead is created and output by using a determination result indicating whether a first inspection result acquired by the first inspection determination satisfies the first determination standard and a determination result indicating whether a second inspection result satisfies the second determination standard.

摘要: The beam rotation device described herein has a base support with a first vertical jaw arm, a second vertical jaw arm, and a support arm. The second vertical jaw arm may be pivotally coupled to the device so as to go from a first, closed position to a second, opened position to receive a steel beam (e.g., I-beam). Once the steel beam is placed within the device, the support arm may hold the beam stationary to allow a worker to weld or perform other tasks. It will be appreciated that multiple beam rotation devices may be coupled together and work in tandem to receive and rotate a beam. The beam rotation device creates a safer working environment than the rotators found in the art by having a pivotable second vertical jaw arm that may open to receive a beam and a support arm to hold the beam during fabrication.

摘要: A BGA structure having larger solder balls in high stress regions of the array is disclosed. The larger solder balls have higher solder joint reliability (SJR) and as such may be designated critical to function (CTF), whereby the larger solder balls in high stress regions carry input/output signals between a circuit board and a package mounted thereon. The larger solder balls are accommodated by recessing each ball in the package substrate, the circuit board, or both the package substrate and the circuit board. Additionally, a ball attach method for mounting a plurality of solder balls having different average diameters is disclosed.
