Patent ID: 8062450

Claim:
An Anisotropic Conductive Film (ACF) attaching method for attaching an ACF on a board by supplying, above the board, an ACF tape having a base tape and the ACF on one side of the base tape except at a terminal end and a beginning end of the base tape, wherein the beginning end is located downstream of the terminal end, cutting the ACF to a predetermined length, and pressing the ACF tape to the board, said attaching method in the case where one of the ends of the ACF tape that is being used is detected, said attaching method comprising: holding, by a first holding unit, the terminal end of the base tape included in the ACF tape that is being used such that the ACF tape that is being used is held under tension; cutting, at a cutting location of the base tape, the terminal end of the base tape upstream from the first holding unit so as to leave a remainder terminal end part of the base tape downstream of the cutting location; holding, by a second holding unit separate from the first holding unit, a beginning end of an additional base tape included in an additional ACF tape such that the additional base tape is held under tension; positioning the remainder terminal end part of the base tape that is being used and the beginning end of the additional base tape to be mutually overlapped in a thickness direction between the first holding unit and the second holding unit, such that the remainder terminal end part of the base tape that is being used is precisely aligned in a width direction with the beginning end of the additional base tape; pressing the overlapped ends of the ACF tapes in the thickness direction to cause splicing of the ACF tapes to thereby form a spliced ACF tape having a spliced portion constituted by the remainder terminal end part and the beginning end that are mutually overlapped; and cutting the beginning end of the additional base tape between the spliced portion of the spliced ACF tape and the second holding unit, wherein said attaching method is repeated using additional ACF tapes.
