A method of making a component includes applying a clamping force to the component, the component coupled to a carrier strip of a panel via a polymeric tab and separating a portion of the polymeric tab from a substrate of the component, thereby causing the component to be detached from the panel.

Removable tabs and methods of making and using the same

Various embodiments concern a method of attaching a microactuator to a flexure, depositing a wet mass of structural adhesive on the flexure, mounting the microactuator on the wet mass of structural adhesive, partially curing the mass of structural adhesive through a first application of curing energy, and depositing a mass of conductive adhesive on the flexure. The mass of conductive adhesive is deposited in contact with the mass of structural adhesive. The state of partial curing of the structural adhesive prevents the conductive adhesive from wicking between the flexure and the underside of the microactuator and displacing the structural adhesive which may otherwise result in shorting to a stainless steel layer of the flexure. The method further comprises fully curing the mass of structural adhesive and the conductive adhesive through a second application of curing energy.

The present disclosure relates to methods and a related systems and tools for dispensing an adhesive piece having damping qualities onto a component of a hard disk drive suspension. The adhesive piece can be commercially available layered strip sold as an adhesive layer having a first and a second liner adhered to each side. An exemplary method can cut an adhesive piece, separate the adhesive piece from a secondary liner, adhere the adhesive piece onto a component of a hard disk drive suspension, separate a primary liner from the adhesive piece, and dispose of the primary liner using a conventional gantry system. The method can be performed using a two-step operation of the gantry system.

Visco pad placement in disk drives

Methods and apparatus concern testing a disk drive suspension. Testing includes moving a first portion of a suspension relative to a second portion. A pair of motors is mounted on the suspension. The testing further includes measuring an electrical signal that is intrinsically produced by the motors, combined in a circuit, in response to the relative movement. The testing further includes identifying a characteristic of the electrical signal and determining whether an orientation of one or both of the motors is reversed relative to an intended motor orientation based on the characteristic of the electrical signal. The testing can determine whether the orientation of both motors matches the intended motor orientation, whether the orientation of one motor is reversed in a same polarity condition, whether the orientations of both motors are reversed in a mutual reverse polarity condition, or whether the suspension has a mechanical or electrical defect.
