Patent ID: 8665567

Claim:
A disk drive comprising: a spindle attached to a disk drive base; a disk mounted on the spindle; a coarse actuator attached to the disk drive base, the coarse actuator including an actuator arm; and a suspension assembly attached to the actuator arm, the suspension assembly including: 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, the microactuator to position a read head; a flexure attached to the bottom-side of the of mounting plate, the flexure including a metal layer, an insulator layer, a trace layer which 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; and a conductive epoxy bonded to the microactuator extending 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.
