  • Publication number: 20230092478
    Abstract: A device and method for weld root hardening determination compensated for variations in distance between sensor and sample are disclosed. A sensor is used to determine hardness of a weld for weld fabrication quality control. Because of irregular weld protrusion geometry, there may be variations in the tip of the sensor and the surface, resulting in inconsistent measurements. To compensate, one or both of a positional compensation or a software compensation are performed. Positional compensation mechanically moves the tip of the sensor to within a predetermined range of the surface. Software compensation may at least partly compensate for the variation by using one part of the generated sensor data (such as the 1st harmonic signal) in order to modify another part of the generated sensor data (such as the 3rd harmonic signal). In this way, the sensor determination of hardness of the weld may be less dependent on the variations.

  • Patent number: 9972509
    Abstract: An anti-plasma adhesive tape utilized for manufacturing a semiconductor package includes a substrate; and an adhesive layer formed on the substrate, wherein the adhesive layer is selected from a group composed of acrylic adhesive, light-curable resin and photoinitiator. The anti-plasma adhesive tape is attached to a backside of a lead frame of the semiconductor package before a plasma-cleaning process and removed from the lead frame after a molding process. After the anti-plasma adhesive tape is cured by irradiating an energy ray and removed from the lead frame, there is no residual adhesive left on a molding compound of the semiconductor package.

  • Patent number: 9762059
    Abstract: A voltage stabilizing module for multi power source input is compatible with multiple input power sources including DC power source and/or AC power source and comprises a plurality of receiving ends, a power source selection unit and a voltage conversion unit. The receiving ends receive the input power sources. The power source selection unit is coupled with the receiving ends to receive the input power sources and sets at least one of the input power sources as a working power source. The voltage conversion unit receives the working power source and keeps the working power source at a working voltage level to act as a voltage signal outputted to a loading.

  • Patent number: 8164290
    Abstract: A fan includes a motor control device which is electrically connected with a motor and an alternating current power source. The motor control device includes a converting circuit, a power factor correction circuit and a motor controlling circuit. The voltage of the alternating current power source is converted to be direct current voltage by the converting circuit and the power factor correction circuit, and then the direct current voltage is outputted to the motor control circuit. The motor controlling circuit generates a driving signal in accordance with the direct current voltage for driving the motor to operate.
