Devices including a substrate and a plurality of coil portions disposed on the substrate. The plurality of coil portions electrically coupled to form a coil structure.

High density coil design and process

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.

Partial curing of a microactuator mounting adhesive in a disk drive suspension

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

Apparatus and method for simultaneously adjusting the gram load and radius geometry height of a head suspension by scanning a spring region of the head suspension with a laser beam. The incremental height difference between left and right legs of a spring region of the suspension may also be concurrently corrected. Apparatus and method for measuring the radius geometry height are provided by two or more non-contacting optical probes. A nitrogen atmosphere may be maintained in the region scanned.
