Abstract: Provided is an apparatus capable of easily splicing ACF tapes that are thin and are hard to handle. The tape splicing apparatus splices two ACF tapes (210) each having an ACF (212), and includes: a first holding unit that holds one of the ACF tapes (210); a second holding unit that holds the other one of the ACF tapes (210); a positioning unit (115) that positions the ACF tapes (210) to be overlapped in a thickness direction; and a pressing unit (116) that presses the overlapped ACF tapes (210) in the thickness direction.

Abstract: A pusher 13 has a leaf spring 12, a driving section 22, a direction changing section 23, and guides 24. The driving section 22 nips the leaf spring to longitudinally advance and retract it. Advancement of a fore end of the leaf spring 12 in a pushing direction causes the object facing the leaf spring to be pushed from a first position to a second position. A direction changing section 23 bends the tail end of the leaf spring relative to the fore end so as to change the direction of advancement and retraction. Guides 24 guide the fore and tail ends with respect to the direction changing section.

Abstract: A bump forming method comprising a first step of forming a ball (5) at a distal end of a wire (4) which protrudes from a lower end of a capillary (12); a second step of opening a damper (11) which securely holds the wire (4) above the capillary (12) and bringing down the capillary (12) as well as the damper (11), in which an amount of movement of the damper (11) is smaller than that of the capillary (12) by such an amount as to be equivalent to a length of the wire (4) being protruded from the lower end of the capillary (12) in the first step; a third step of forming a bump (21) from the ball (5) by bonding; and a fourth step of separating the wire (4) from the bump (21) by closing the damper (11) and lifting up the damper (11) and the capillary (21) to an initial position of the first step as well as causing a distal end of the wire (4) to protrude from the lower end of the capillary (12) by a predetermined length, whereby a step of drawing out a leading end of the wire (4) from the capillary (12) is elimina
