Scheme to avoid electrostatic discharge damage to MR/GMR head gimbal/stack assembly in hard disk applications

摘要

A flexible circuit board which can be assembled into a head gimbal assembly of a hard disk drive. The flexible circuit board may have a conductive tab that is electrically connected to a pre-amp pad and a head pad of the circuit board. The head pad may be connected to a head. The conductive tab may be grounded during handling of the flexible circuit board. Any electrostatic discharge on the head may be grounded through the conductive tab.
