摘要： A head suspension or head suspension component article configured for solder ball bonding of a head slider to electrical traces on article. The article including electrical traces formed from electrically conductive material with the electrical traces having a bonding region adapted for electrical bonding to a head slider. Also included is a support structure providing support for at least portions of the electrical traces and including a head slider mounting region adapted to receive the head slider. This structure is configured to mechanically and thermally isolate the bonding region of the electrical traces from the head slider mounting region to reduce mechanical and thermal effects of a solder ball bonding process on the article during solder ball bonding of the head slider to the electrical traces. The support structure may be reduced at or around the bonding region, or the conductive material may be increased to dissipate more heat.

摘要： A magnetic disk drive system that has a suspension assembly that includes a slider having a heating element and a suspension configured with a protective structure that protects the heating element. The heating element of the slider can extend through the suspension to extend from the suspension assembly from a side that is opposite the slider. The protective structure is configured to protect the heating element and to prevent the heating element from contacting the heating element of an adjacent suspension during an event such as a physical shock to the disk drive system.

摘要： An interleaved conductor structure for electrically connecting the read/write electronics to a read/write head in a hard disk drive is provided. The interleaved conductor structure may allow for an increased characteristic-impedance range, greater interference shielding and a reduction of signal loss that is contributed by a lossy conductive substrate. The electrical traces may have different widths, be offset, or even wrap around each other at the via connections.

摘要： A head suspension for a head/gimbal assembly comprises a flexure attached to a load beam. The load beam includes a lifter tab configured to engage a lifting surface of a load/unload ramp. The flexure includes a limiter tab, extending from a trailing edge thereof, that is configured to engage with a gimbal-limiting surface of the load/unload ramp. The limiter tab comprises a metallic base layer, a metallic stiffening layer, and a non-metallic intermediate layer disposed between the base and stiffening layers. The stiffening layer can include both conductive traces that terminate with a set of bonding pads and an appendage that extends along a length of the limiter tab. The appendage portion of the stiffening layer serves to increase the thickness of the limiter tab to increase the stiffness of the limiter tab.

摘要： Approaches for integrated lead suspension that provides many benefits, such as enabling a dual stage actuator (DSA) to be used with a single layer flex with a reduced amount of crosstalk. An integrated lead suspension comprises a tail end having a plurality of conductive pads positioned thereat. The plurality of conductive pads includes a first and second dual stage actuator (DSA) pad. The first and second DSA pads are electrically coupled to a conductive member by way of conductive vias. The conductive member may be a stainless steel island. The first DSA pad conducts a signal to a first terminal at each of a plurality of dual stage actuators, while a second terminal at each of the plurality of dual stage actuators is connected to ground.
