Abstract: A tool is equipped with a torque sensor, suited for a tightening task of a fastening component of a device such as a fluid control system that requires a large number of fastening components for assembly and has a narrow space for access to the fastening components, and capable of automatically detecting a tightening torque. The tool includes a torque sensor capable of detecting a tightening torque for tightening a fastening component acting on a bit. The torque sensor initiates measurement of the tightening torque when the tightening torque detected exceeds a set threshold value, completes measurement when the tightening torque detected falls below the set threshold value and a set time elapses, and outputs torque-related data formed on the basis of measurement data from measurement initiation to measurement completion and including a measurement time. The torque-related data includes a peak value of the measurement data.

Abstract: A head that moves across a surface of a mask, which includes a plurality of apertures for disposing conductive balls on a substrate, whereby, while the head is rotating about an axis that is perpendicular to the mask, the axis moves across the surface of the mask. The head includes a gatherer that gathers the conductive balls into a circular area that is smaller than the surface of the mask and disposed around a center of rotation of the head, the conductive balls being gathered from an area around the circular area when the head rotates.

Abstract: A method of mounting conductive balls comprises a step of setting, on a substrate, a mask that includes a plurality of apertures for disposing conductive balls on the substrate and a filling step. The filling step includes using a head that moves along a surface of the mask, holding a group of conductive balls in an area that is part of the surface of the mask, and moving the area so that parts of a path taken by the area overlap. By limiting the area where filling is carried out and moving the conductive balls while gathering the conductive balls in this area, it is possible to prevent losses for the conductive balls, to increase the filling efficiency, and to suppress the number of unfilled apertures.
