Abstract: A flexure of a disk drive suspension includes a metal base, and a wiring portion provided along the metal base. The wiring portion includes a base insulating layer, a conductor layer overlapping with the base insulating layer, and a cover insulating layer overlapping with the conductor layer, and the metal base includes a pair of first portions having side surfaces opposed to each other. At least one of the base insulating layer and the cover insulating layer is in contact with the side surfaces between the pair of first portions, and the conductor layer does not overlap with the metal base in a direction of stacking the wiring portion.

Abstract: A circuit member includes a metal base, an insulating layer, a conductor, and a cover layer. A terminal portion includes a thick portion formed on a side part of the insulating layer, and an extension portion, which is a part of the conductor, overlapping the thick portion. The extension portion includes a side pad portion along a side surface of the thick portion. A side surface of the side pad portion constitutes a side pad extending in a thickness direction of the conductor. A length of the side pad in a thickness direction is greater than a thickness of the conductor. A side pad insulating portion, which is formed of a part of the thick portion, is formed between a distal end of the metal base and the side pad portion.

Abstract: A first terminal provided on a tail pad portion includes a base portion, a bent portion and an overlapping portion. The base portion includes a first surface fixed to a base insulating layer and a second surface on an opposite side to the first surface. The bent portion is reversed in a thickness direction of the base portion from an end of the base portion towards the second surface. The overlapping portion extends from the bent portion in a direction along the second surface. An anisotropic conductive film (ACF) is disposed between the overlapping portion and the second terminal. The overlapping portion and the second terminal are connected to each other via the ACF.

Abstract: A flexure includes a metal base, a base insulation layer formed on the metal base, a terminal formed on the base insulation layer, a conductor portion electrically conductive to the terminal and an detouring extending portion formed on the conductor portion. The conductor portion includes a conductor and a cover layer covering the conductor. A conductive adhesive is supplied to the terminal. The detouring extending portion is formed in a longitudinal middle of the conductor portion and extends from the side surface of the conductor portion in a direction intersecting the length direction of the conductor portion along the base insulation layer.

Abstract: A circuit member includes a metal base, an insulating layer, a conductor, and a cover layer. A termial portion of the circuit member includes a thick portion formed at a part of the insulating layer, a conductor convex portion which is a part of the conductor, and overlaps the thick portion, and a conductor extending portion. By the conductor convex portion and the conductor extending portion, a stepped side pad is formed. The stepped side gad includes a first surface along the conductor extending portion, and a second surface which rises in a thickness direction of the conductor extending portion. The stepped side pad and an element are connected by a conductive member.

Abstract: A flexure chain blank sheet includes a plurality of frame units. Each of the frame units includes a frame portion, and a plurality of flexure elements arranged within the frame portion. The frame portion includes lengthwise frames extending in a longitudinal direction of the flexure elements, and lateral frames extending in a width direction of the flexure elements. A slit that extends along the lateral frames, a connection portion, and recesses are formed between adjacent frame units. An opening width of the recesses is greater than an opening width of the slit. The connection portion includes a portion-to-be-cut which is to be cut by a cutter. The recesses allow insertion of the cutter.
