A head gimbal assembly for a hard disk drive comprises a flexure having a planar surface and a standoff structure extending from the planar surface, where the standoff structure includes a monolithic element. A head slider in which a read-write head is housed is adhered to the flexure with an adhesive, such that the adhesive surrounds the monolithic element so that the monolithic element may absorb strain energy caused by curing of the adhesive.

Approaches to a flexure gimbal assembly for a hard-disk drive (HDD), having a feature for reducing the risk of electrical shorts, include a flexure having an electrically conductive layer and an insulating layer having a flexure tongue with which one or more microactuator piezo actuating device is coupled, where the flexure tongue comprises a gap positioned to inhibit contact between the conductive adhesive and the conductive layer of the flexure which may otherwise cause an electrical short.

Dual stage microactuator flexure feature for minimizing electrical shorts

A head-gimbal assembly. The head-gimbal assembly includes a suspension, a microactuator disposed on the suspension, and a head-slider bonded to the microactuator. The head-gimbal assembly further includes a connection pad disposed on the suspension, a connection pad disposed on the microactuator and formed over an edge between a side surface and a top surface of the microactuator to have a bend portion with an obtuse angle, and a metallic interconnection joint for interconnecting the connection pad of the suspension with the connection pad of the microactuator.

Head-gimbal assembly, microactuator, and manufacturing method of the microactuator

A method for manufacturing a head-gimbal assembly. The head-gimbal assembly includes a head-slider bonded to a suspension. The method includes placing the head-slider and the suspension in a superposed manner with a photo-thermosetting adhesive applied between the head-slider and the suspension. The method also includes heating the suspension from a side of the suspension opposite to a side of the suspension in contact with the photo-thermosetting adhesive with a heated gas-stream. In addition, the method includes irradiating the photo-thermosetting adhesive with light at least partly in a time period during which the suspension is heated by the gas-stream.

Method and apparatus for manufacturing a head-gimbal assembly

Approaches for helping to decrease the amount of inactive gas necessary for reflow to interconnect connection terminals of a head slider and a suspension. Inactive gas is blown from a nozzle of a reflow apparatus toward interconnection joints of a head slider and a suspension. The head slider is bonded onto a gimbal tongue. The nozzle comprises a duct through which the inactive gas passes and a porous member fitted in an ejection outlet of the tube. Placing the porous member close to the head slider achieves effective reduction of oxygen concentration around solder balls.
