Assembly method for actuator head suspension assembly

摘要

Embodiments of the invention provide a method for easily and reliably neutralizing charge in an assembly process for an actuator head suspension assembly used in a magnetic disk device. In one embodiment, a head suspension assembly includes a wire trace that includes a laminated structure of a metal layer, a first dielectric layer, a conductor layer, and a second dielectric layer. The conductor layer includes an exposed portion exposed from the second dielectric layer. The suspension assembly also includes a head/slider supported by the metal layer. An actuator assembly includes an actuator arm and a flexible printed circuit board. The exposed portion of the conductor layer is immersed in a charge neutralizing solvent. The head suspension assembly is mounted to the actuator arm. A terminal of the wire trace is connected to a terminal of the flexible printed circuit board.
