ABSTRACT:
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.
