Claim Text:
1. A flexure assembly for a hard disk drive, comprising: a flexure comprising: a microactuator comprising one or more piezo actuating devices coupled to said flexure tongue with electrically conductive adhesive and configured to provide a moment force for rotating a head slider in response to a negative bias driving voltage provided by said voltage source trace; and in response to said one or more piezo actuating devices receiving said negative bias driving voltage provided by said voltage source trace, which provides for a negative root mean square (RMS) AC voltage to said one or more piezo actuating devices across at least a majority of a corresponding AC waveform, (a) ions or atoms or (b) ions and atoms of said electrically conductive adhesive are inhibited from migrating to said electrically conductive spring layer of said flexure.
