Head stack assembly with a laminated flexure having a snap-through feature
Abstract:
A novel head stack assembly (HSA) includes a flex cable with a first side and an opposing second side, and having a hole therethrough. The HSA also includes a head gimbal assembly (HGA) having a load beam, a laminated flexure attached to the load beam, and a head attached to the laminated flexure. The laminated flexure includes a flexure tail with a snap-through feature. The snap-through feature has a plurality of windows in the flexure tail, a snap-through feature central portion that is centric to the plurality of windows, and a plurality of lobes. Each lobe extends out from the snap-through feature central portion radially into one of the plurality of windows. The laminated flexure overlies and contacts the flex cable on its first side, but the snap-through feature is disposed through the hole so that each of the plurality of lobes contacts the flex cable on its second side.
