  • Publication number: 20230146315
    Abstract: There is provided an Al bonding wire which can achieve a sufficient bonding reliability of bonded parts of the bonding wire under a high temperature state where a semiconductor device using the Al bonding wire is operated. The Al bonding wire contains 0.01 to 1% of Sc, and further contains 0.01 to 0.1% in total of at least one or more of Y, La, Ce, Pr and Nd. With regard to the Al bonding wire, a recrystallization temperature thereof is increased, so that the proceeding of recrystallization of the bonding wire can be suppressed, and strength of the wire can be prevented from being decreased even when the semiconductor device is continuously used under a high temperature environment. Accordingly, the Al bonding wire can sufficiently secure the reliability of the bonded parts after a high-temperature long-term hysteresis.

  • Patent number: 11571771
    Abstract: If a flux contains an amount of thixotropic agent necessary for obtaining the effect of suppressing a heating sagging, the amount of flux residue increases, and, if applied for uses that do not involve washing, a large amount of flux residue derived from the thixotropic agent remains around the soldered portions, thereby affecting chemical and electrical reliability; and that washing performance is poor in uses involving washing of the flux residue. Accordingly, this soldering flux contains nanofibers of one or more kinds from among polysaccharides, modified polysaccharides, and incompletely modified polysaccharides being modified from polysaccharides into modified polysaccharides, by an amount of 50 wt ppm or more and 3000 wt ppm or less with respect to a total amount of flux.

  • Publication number: 20220407600
    Abstract: A computation unit uses an assumed chromatic dispersion amount to compensate for dispersion of a coherently received optical signal and performs arithmetic of a signal power of the optical signal that is dispersion compensated. The computation unit performs computation of an evaluation function when a signal power and a delayed signal power obtained by applying a predetermined delay to the signal power satisfy a threshold condition. The evaluation function is a function for evaluating whether the assumed chromatic dispersion amount is a chromatic dispersion amount of the optical signal using the difference between the signal power and the delayed signal power. The chromatic dispersion amount calculation unit calculates a chromatic dispersion amount of the optical signal based on the computation result of the evaluation function by the computation unit when each of a plurality of different assumed chromatic dispersion amounts is used.

  • Patent number: 11500353
    Abstract: In a robot system, a data amount of operation information (log) to be transferred or recorded is reduced, thereby enabling the operation information (log) to be transferred or recorded with a low load. The system has a control unit for controlling the operation of a robot of a robot device and transfers a log regarding the robot operation to a managing terminal. While making the robot operative, the control unit generates log data regarding the robot operation and stores into a short-term storage log recording unit (temporary storage device) (log data generating step). When log transfer timing comes, a part of the log data stored in the recording unit (temporary storage device) is extracted and transferred as a log to a log storage device in accordance with the robot operation (log transferring step).
