Abstract

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.
