  • Publication number: 20170205224
    Abstract: Conventionally, the volume of a product has been measured by using a method called a light section method only from a single direction. When the inclination of its surface is steep with respect to an incident light ray, the precision is low. The present invention includes a processing step that processes a component, an examination step that measures and calculates the volume of the component discharged from the processing step by using an optical method, an evaluation step that compares the volume value of the component obtained at the examination step with a previously set reference value to determine the quality of the component, a branching step that sorts and branches the component based on the evaluation result of the evaluation step, and a conveyance step that conveys the component branched at the branching step. This provides a method for manufacturing a high-precision component.

  • Publication number: 20100080915
    Abstract: When a position of a film formation mask is recognized by irradiating the film formation mask with light, an image having a high contrast cannot be obtained, which unstabilizes reproducibility of measurement accuracy for an alignment mark position, leading to an alignment error between a substrate and a mask. Provided is a film formation mask including a mask sheet having a positioning opening and a mask frame, in which a reflective member having a reflectance higher than that of the mask sheet is provided to the positioning opening. When light is irradiated onto the positioning opening of the film formation mask, an intensity difference between light reflected by the mask sheet and light reflected by the reflective member becomes stable. Therefore, the position of the film formation mask may be determined with high reproducibility.
