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 transducer suspension system has a transducer head, laminated member, and a load beam. The laminated member is comprised of a support layer, an electrically insulating layer, and an electrically conducting layer. The electrical lines are formed directly into the laminated member. A first end of the support layer has an aperture into which a tongue section protrudes. The transducer head is attached to the tongue section. A platform section is formed between the aperture and the end of the support layer. The electrical lines run to the transducer head along the platform section. The load beam is attached to the laminated member and provides rigid support. The load beam has an aperture located directly above the platform section and provides access to allow clamping of the electrical lines and the platform section during electrical attachment of the lines to the transducer head. Precise electrical attachment is achieved without unwanted bending of the delicate flexure section of the suspension.

摘要： MR heads having MR sensors are protected against damage caused by electrostatic discharge or the presence of electrostatically charged fields. A shunt is provided across the adjacent conductive leads or traces to the MR sensor at a point that is immediately adjacent their termination on the MR head. A solder bridge may be used for the shunt. The solder shunt is removed prior to putting the integrated suspension on which the MR head is mounted into operation in a magnetic disk drive system. The solder shunt is removed by reflowing the solder and drawing the reflowed solder away from the leads to break electrical connection of the shunt across the adjacent leads to the MR sensor. To facilitate removing the shunt by reflowing the solder, at least one solder lobe of a chosen geometry is placed adjacent a lead. This lobe includes a confining lobe which serves to confine the solder in the shunt region when the shunt is formed, and a designated portion which serves to draw the solder to a designated location away from the shunt region upon subsequent solder reflow, thereby causing a physical break in the shunt. Physical removal of the solder material would not be required. The shunt may also be in the form of an integral bridge of conductive material interconnecting the adjacent leads, which is removed by using a laser to melt the material.

摘要： An integrated suspension for a slider in a magnetic storage system has a simplified structure that is relatively easy to manufacture. 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 leads integrally formed thereon. A section of the flexible member is fixedly attached to the load member, and another section having the slider mounted thereon presses against a pivot projection in the load beam for gimbal motions. An interlocking structure is provided to limit the extent of gimbal motions of the flexible member, comprising a tab extending from the flexible member into an aperture in the load beam. Alternatively, a tang is formed in the flexible member which is used to form a clip which serves to limit gimbal motions as it interacts with the load beam.

摘要： An integrated lead suspension is formed from a laminate of three materials in a variety of configurations having from three to five layers. The materials are stainless steel, polyimide and copper. Each layer is essentially homogeneous, but may be formed with one or more holes or voids prior to the formation of the laminate. The voids allow dielectric material to be removed from the area beneath the conductors to simplify processing and reduce the cost of the suspensions. The voids can also form a window through which conductors can be shorted to other conductive layers to form an electrostatic discharge shunt. Alternatively, the shorting of conductors can be used as a cross-over for various conductors.

摘要： An integrated lead suspension is formed from a laminate of three materials in a variety of configurations having from three to five layers. The materials are stainless steel, polyimide and copper. Each layer is essentially homogeneous, but may be formed with one or more holes or voids prior to the formation of the laminate. After the copper layer is etched to form a tab which overhangs the steel layer, the suspension is welded to a load beam. The load beam prevents the downward motion of the suspension. The tab acts as a flexure motion limiter for upward motion of the suspension. The voids allow a precise amount of polyimide undercut between the steel and copper layers which otherwise could not be achieved.

摘要： The present invention is an integral magnetic head suspension and method for making the same. The integral suspension, with or without the head, contains integrated conductive circuits that have multiple cross overs for noise reduction. The suspension is fabricated completely on silicon (Si) wafers using semiconductor processes. A N+ silicon layer is disposed over a P- silicon wafer. The N+ silicon layer and the P- silicon water are thermally oxidized to generate a bottom silicon oxide layer opposite the N+ layer side of the wafer and a top silicon oxide layer on the N+ side of the wafer, and to drive the N+ silicon into the P- silicon wafer. A layer of polysilicon is disposed over the silicon oxide layer on top of the N+ silicon layer. One or more pairs of conductive traces having multiple cross-overs are fabricated on the layer of polysilicon. Optimally, a magnetic head is simultaneously fabricated on the suspension. The polysilicon layer is then patterned to define the head structure and suspension structure as one piece. Finally, the magnetic head and suspension are separated from the wafer by removing the first silicon oxide layer by a chemical etchant and the P- silicon wafer by selective etching. The head and suspension are released from the silicon wafer as a single structure using the above-described semiconductor processes. Accordingly, no grinding or cutting is used to define the dimensions of the head. Further, no processes are required to attach the head to the suspension and the suspension can be made from low mass materials such as silicon (Si) or Al.sub.2 O.sub.3.
