Embodiment Construction

[0011] figure 1 Is a perspective view of an example hard disk drive HDD system 20, which includes a magnetic storage disk 22 rotating about an axis 24, an actuator motor 26 (such as a voice coil motor), an actuator arm 28, a suspension assembly 30, and a transducer head carrying The slider 32 (such as figure 2 shown). Slider 32 is supported by suspension assembly 30 , which is in turn supported by actuator arm 28 . The actuator motor 26 is configured to pivot the actuator arm 28 about the axis 34 so as to cause the suspension assembly 30 and the slider 32 to sweep in an arc across the surface of the rotating disk 22 while the slider rides on a cushion of air. "Slide over" or "fly over" the disk 22. A transducing head carried by slider 32 is positionable relative to selected concentric data tracks 36 of disc 22 for reading and writing from disc 22 . It should be noted that stacks of co-rotating disks 22 may be provided, with additional actuator arms 28, suspension assembli...

Abstract

A slider includes a slider body and a bond pad. The bond pad is positioned on the slider body and has a bonding surface with a recessed channel for directing solder flow.

Description

Background technique [0001] HDDs typically include one or more disks. A transducing head carried by a slider is used to read and write data tracks on the disc. The slider is carried by an arm assembly comprising an actuator arm and a suspension assembly which may comprise a separate gimbal mechanism or may integrally form the gimbal. The slider typically includes bond pads where the slider is connected to suspension bond pads on the suspension assembly by a thermal interconnect process (TIC). During the TIC process, molten solder is applied between the slider bond pad and the suspension bond pad and cooled to form the connection. [0002] The form factor (size and shape) of sliders has steadily decreased since the advent of HDDs. There has also been a trend to increase the number of bonding pads for additional electrical connections to the slider. Therefore, the size of the bonding pads, as well as the space between the bonding pads is also reduced. As these dimensions ge...
