Abstract
Disclosed is a suspension assembly for a disk drive that includes: a mounting plate having a through-hole extending from a top-side of the mounting plate to a bottom-side of the mounting plate; a microactuator mounting structure formed in the mounting plate; a microactuator mounted in the microactuator mounting structure; and a flexure attached to the bottom-side of the of mounting plate. The flexure includes: a metal layer; an insulator layer; a trace layer that includes a ground trace; and an opening, wherein the opening extends through the metal layer and the insulator layer to a gold-plated ground trace. A conductive epoxy is bonded to the microactuator and extends through the through-hole to bond to the flexure, wherein the epoxy extends through the opening of the flexure to the gold-plated ground trace of the flexure such that the microactuator is grounded to the flexure.
