Method of reclaiming a head suspension from a head gimbal assembly

摘要

A method of reclaiming a head suspension includes detaching a slider 225 from a tongue 221 of the head suspension and removing an adhesive 227 remaining on the tongue 221. Removing the adhesive 227 remaining on the tongue 221 includes feeding a solvent 243, which promotes the removal of the adhesive 227, to a part of the tongue 221 where the adhesive 227 remains and promoting the removal of the remaining adhesive 227 from the tongue 221 by applying physical energy to the adhesive remaining part on the tongue 221. The physical energy is produced by heating, supersonic vibration, and the like. The method easily removes the adhesive 227 from the tongue 221 without directly applying mechanical force to the tongue 221, thereby improving yields.

1. A method of reclaiming a head suspension from a head gimbal assembly, the head gimbal assembly including the head suspension and a slider, the slider including a read/write magnetic head and being attached with an adhesive to a tongue of the head suspension, the method comprising:
detaching the slider from the tongue of the head suspension wherein the adhesive remains on part of the tongue and is mainly formed of a thermosetting resin material that forms a network structure when heated; and removing the adhesive remaining on the tongue by:
feeding a solvent to a part of the tongue where the adhesive remains, the solvent being one that promotes the removal of the remaining adhesive from the tongue; promoting the removal of the remaining adhesive on the tongue to which the solvent has been fed by subsequently applying, in a single step, both physical energy and supersonic vibration to the adhesive remaining part on the tongue to which the solvent has been fed, the physical energy being produced by heating the adhesive remaining part on the tongue to which the solvent has been fed, and the supersonic vibration vibrating the tongue and the adhesive remaining part on the tongue to which the solvent has been fed at supersonic frequency such that the combined application of the physical energy produced by heating and the supersonic vibration combine in order to promote the removal of the adhesive remaining part on the tongue and thereby to remove the adhesive remaining on the tongue.
