  • Patent number: 10388624
    Abstract: An anisotropic conductive film includes an insulating adhesive layer and conductive particles disposed thereon. Arrangement axes of the conductive particles having a particle pitch extend in a widthwise direction of the film, and the axes are sequentially arranged with an axis pitch in a lengthwise direction of the film. The particle pitch, axis pitch of the axes, and an angle ? of the axes relative the widthwise direction of the film are determined according to external shapes of terminals so 3 to 40 conductive particles are present on each terminal when a terminal arrangement region of an electronic component is superimposed on the film so a lengthwise direction of each terminal is aligned with the widthwise direction of the film. By using the film, stable connection reliability is obtained and an excessive increase in the density of the conductive particles is suppressed even in the connection of fine pitches.

  • Publication number: 20190243804
    Abstract: A method for deleting obsolete files from a file system is provided. The method includes receiving a request to delete a reference to a first target file of a plurality of target files stored in a file system, the first target file having a first target file name. A first reference file whose file name includes the first target file name is identified. The first reference file is deleted from the file system. The method further includes determining whether the file system includes at least one reference file, distinct from the first reference file, whose file name includes the first target file name. In accordance with a determination that the file system does not include the at least one reference file, the first target file is deleted from the file system.
