    Abstract: In a data recording disk file a slider (16) is mechanically attached to the suspension (40) by means of reflowed solder balls (80). A pattern of solder contact pads (70) is formed on the back side of the slider and a similar pattern of solder-wettable regions (60,61,63) is formed on the suspension. Solder balls are formed on either the solder contact pads or the solder-wettable regions, the slider is located on the suspension so that the solder balls are in registration between the solder contact pads and solder-wettable regions, and the solder is heated to reflow, thereby forming solder joints (80,86) as a mechanical connection between the slider and suspension. When a thin film transducer (11,13) is formed on the slider trailing edge (26) and the suspension is a laminated type with patterned conductors (46,55), solder balls are also formed on the transducer lead terminations (19,21; 27,29) on the trailing edge and on a row of solder-wettable regions (61,63) on the suspension near the location where the trailing edge of the slider is to be located. In this embodiment, when the slider with thin film transducer, with solder balls on the lead terminations, is located over the suspension then all of the solder balls are heated. The solder balls for providing mechanical connection collapse during reflow, thereby causing the solder balls on the transducer lead terminations to come in contact with and flow together with the solder balls formed on the row of solder-wettable regions on the suspension. Thus the mechanical attachment of the slider is made simultaneously with the electrical connection of the transducer leads to the disk file read/write electronics.

    Abstract: A thin film magnetic read/write head/arm assembly and method of manufacturing the same is disclosed herein. Contact soldering (37) of the opposite to disk side of the read/write head (35) to a cable (33) in laminate relationship to the suspension arm (31), or a polyimide strip with conductors deposited thereon provides both electrical interconnection and mechanical support. Semiconductor devices (40) can also be intermediately soldered between the head and cable for maximum noise suppression.
