    摘要： A method for shorting, unshorting, and reshorting an electronic component such as an MR sensor provides a repeatable ESD protection scheme. A conductive line of an electrically conductive first shorting material is created between electrical leads operatively coupled to an electronic component for creating a short therebetween. The short is severed using a laser. The short is recreated by applying a second shorting material, which may or may not be the same as the first shorting material.

    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.

    摘要： A disk drive has an improved electrical interconnect assembly for coupling one or more conductive paths leading from a read/write head with the conductive terminals of a flexible cable. The improved interconnect assembly includes an interconnect tab with a plurality of interconnect pads attached thereto. The interconnect tab is connected to a suspension assembly containing a planar suspension member which is located and secured on the actuator arm such that the interconnect tab extends beyond the peripheral edge of the actuator arm. The interconnect tab is inclined toward the side of the actuator arm opposite the side on which the suspension assembly is mounted. The end of the inclined interconnect tab extends to a distance from the planar suspension member approximately equal to half the thickness of the actuator arm. The flexible conductive cable has conductive paths connected to an array of terminals which is oriented at an incline wherein each terminal is aligned with a corresponding interconnect pad. Each flexible cable terminal and corresponding interconnect pad defines an L-shaped joint that is electrically coupled by an electrically conductive fillet, thereby electrically interconnecting the read/write head to the flexible conductive cable. More than one suspension assembly utilizing this improved electrical interconnect assembly can be secured to a single actuator arm and multiple actuator arms can be used in a single disk drive. The interconnect assembly allows the disks to be spaced closer together by better utilization of the vertical space occupied by the actuator arms and disks.
