Abstract
In a dual stage actuated suspension, the conductive adhesive that forms the ground connection bridge from the ground electrode of the PZT microactuator to the grounded stainless steel layer of the flexure, extends from the ground electrode of the PZT around an edge of the stainless steel layer and to a side of the stainless steel layer that is opposite the side of the stainless steel layer to which the PZT is mounted. An aperture in the load beam allows a stream of hot air during the epoxy cure step to be directed directly onto the conductive epoxy ground connection bridge, thus allowing that conductive epoxy ground connection to be reliably and completely cured.
