    摘要： Apertures are formed in the portion of a flexure adjacent to the soldered portions between the bonding pads of the slider and the lead pads of lead end portions. With this, an adhesive agent for bonding the slider to a flexure tongue is moved downward from the apertures so there is no fear that the adhesive agent will contact the lead pads and the bonding pads. This design prevents the protrusion of an adhesive agent from short-circuiting the flexure, and absorbs a warp produced by shrinkage of a soldered portion by decreasing rigidity of the flexure. When both the bonding pad formed on the slider and the lead pad of a lead fixed to the platform of the flexure are disposed and soldered, the quality of the soldered portion is improved by locating the pads as close to each other as possible.

    摘要翻译： 在与滑块的接合焊盘和引线端部的引线焊盘之间的焊接部分相邻的挠曲部分中形成有孔。 由此，用于将滑块结合到挠曲舌的粘合剂从孔向下移动，因此不用担心粘合剂将接触引线焊盘和焊盘。 这种设计防止了粘合剂的突起使挠曲变短，并且通过降低挠曲的刚度来吸收由焊接部分的收缩产生的翘曲。 当形成在滑块上的接合焊盘和固定到弯曲部的平台的引线的引线焊盘都被布置和焊接时，通过将焊盘尽可能靠近地定位来改善焊接部分的质量。

    摘要： A capillary tube for a solder ball connection device connects a first connection surface of a pad to a second connection surface of a pad with a solder ball. The first connection surface is formed at a slider held by a slider holder in a disk unit. The second connection surface is formed at an end of a lead wired to the slider holder. The capillary tube has a ball regulator with a substantially conic, hollow portion. The solder ball regulator has an opening at its top that opens to the tip of the hollow portion. The center axes of the hollow portion and the opening are common. The solder ball regulator also has a pair of projections along the center axis around the opening, where the projections face each other with the center axis therebetween. The projections regulate the movement of the solder ball. The tip of the hollow portion is tapered when viewed from a line connecting the pair of projections and the extreme tips of the tapered tip portions.

    摘要： A method for forming a head gimbal assembly in which the head gimbal assembly and a frame are formed from a continuous piece of laminated material comprised of a first layer, a second layer and a third layer. A plurality of electrical lines are formed in the third layer of the head gimbal assembly and a plurality of electrical line extensions are formed in the third layer of the frame. The slider is positioned at an angle to the frame and a plurality of termination pads on the slider are bonded to the electrical lines. The frame is partially separated from the head gimbal assembly and the relative position of the slider to the head gimbal assembly is changed by an amount sufficient to separate the plurality of electrical lines from the plurality of electrical line extensions.

    摘要： A method of making a solder connection between a slider pad and a suspension pad is provided by forming a solder bump on the solder pad at the slider level, affixing the slider to the suspension so that solder can be reflowed between the slider pad and the suspension pad and then employing a laser beam to reflow at least the solder bump to form a solder connection between the slider pad and the suspension pad. Various embodiments of the method are employed for forming the solder connection. Geometric features are also optionally incorporated in the suspension pad region of the integrated suspension that can be employed to bias the suspension pads against the solder bumps in the pre-reflow state.

    摘要： Disclosed is an improved slider-suspension electrical interconnect assembly and a method of manufacturing the same. The novel integrated suspension may be assembled from separate pieces, including a load beam, a flexure and a mounting plate. The load beam provides rigid structural support of the flexure. The flexure includes a flexible member and conductive leads integrally formed thereon. The flexible member has a gimbal area to which a slider is attached. At least one transducer is attached to the slider for reading data from and writing data to a disk surface. Each of the conductive leads terminates at one end on contact pads on the end face of the slider for electrical connection to the transducer. At the slider termination end, the conductive leads comprise an altered and an unaltered section. The altered section of the conductor has a lower yield strength than the conductor surrounding the altered section, and has a more uniform grain structure than the unaltered section. The altered, stress relieved section of the conductor is formed by treating the lead at the slider termination end with localized infrared radiation.
