Suspension assembly having a microactuator grounded to a flexure

具有接地到挠曲件的微致动器的悬浮组件

Abstract

本发明公开一种用于磁盘驱动器的悬浮组件,包括:安装板,其具有从安装板的顶部延伸到安装板的底部的贯穿孔;在安装板中形成的微致动器安装结构;安装在微致动器安装结构中的微致动器;以及挠曲件,附接到安装板的底部。挠曲件包括金属层、绝缘体层、包括接地轨迹的轨迹层、以及开口,其中开口延伸通过金属层和绝缘体层到镀金接地轨迹。导电环氧树脂结合到微致动器并且延伸通过贯穿孔以结合到挠曲件,其中环氧树脂延伸通过挠曲件的开口到挠曲件的镀金接地轨迹,使得微致动器接地到挠曲件。
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.
