Problems solved by technology

Therefore, it is required to perform a peeling process of removing the thermosetting adhesive on the flexible frame 202. However, in the peeling process, since the thermosetting adhesive is forcibly removed using a solvent or the like, there is a concern that secondary damage may occur. what we don't want

Embodiment Construction

[0024] figure 1 It is a plan view showing an example of a magnetic head assembly (completed state) for a hard disk drive to which the slider peeling method of the present invention is applied. The magnetic head assembly 1 includes: a slider 11 incorporating an electromagnetic transducing element (magnetic head) 13, and a first thermosetting adhesive 15 and a second thermosetting adhesive 16 ( figure 2 , Figure 4 ~ Figure 6 ) to bond the flexible frame 21 on the back side of the slider 11.

[0025] The first thermosetting adhesive 15 has a resin material formed into a network structure by heating as a main material, and the main resin may be, for example, epoxy resins, phenols, urethanes, or the like. This first thermosetting adhesive 15 may have both properties of thermosetting and UV (ultraviolet) curing. Adhesives that have both thermosetting and UV-curing properties, are photopolymerizable, and are based on prepolymers or oligomers that have the property of being heat...

Abstract

The present invention provides a slider stripping method. In a magnetic head assembly including: a slider 11 having an electric / magnetic converting element 13 integrated with the slider; and a flexible flexure 21 to which the slider is adhered by thermosetting adhesive 15, 16, when a property of the slider 11 is defective, the thermosetting adhesive 15, 16 are heated from the flexure 21 side while cooled from the slider 11 side in advance, then the slider 11 is stripped from the flexure 21. Thereby, adhesion of the thermosetting adhesive 15, 16 and the flexure 21 is released, and the thermosetting adhesive 15, 16 are stripped from the flexure together with the slider 11. Thereby, the slider stripping method can be stripped easily from a flexure in a state in which thermosetting an adhesive is adhered to a slider side.

Description

technical field [0001] The present invention relates to a method of peeling off a slider for reusing parts when the characteristics of the slider are defective in a magnetic head assembly. Background technique [0002] Hard Disk Drives (HDD) use so-called magnetic head assemblies such as Figure 7 As shown, there is provided a flexible frame 202 made of a flexible metal sheet fixed on the load beam 203 by, for example, spot welding, and a slider 201 integrally formed with a magnetoresistive effect element is connected to the front end of the flexible frame 202. The space between the ABS (Air Bearing Surface) surface of the slider 201 and the hard disk is maintained by the balance of the elastic force of the load beam 203 and the fluid force generated between the slider 201 and the rotating hard disk drive. On the surface of the flexible frame 202, the flexible wiring substrate 204 ( Figure 8 ). [0003] This magnetic head assembly undergoes a dynamic characteristic check ...
