Patent attributes
A hard disk drive head slider housing a read-write transducer includes electrical pads for bonding with a suspension flexure, electrically conductive bonding studs each extending into the slider body from a corresponding bonding pad, electrical pads for testing where each is positioned proximate to and at a distance from a corresponding bonding pad, electrically conductive testing studs each extending into the slider body from a corresponding testing pad, and a conductive layer within the slider body for electrically connecting a bonding pad with a corresponding testing pad via respective bonding and testing studs. This arrangement accomplishes the effects of a commonly-employed anti-wetting overlay separating the testing pad from the bonding pad, without the added cost, capital expenditure, process and yield difficulties associated with the anti-wetting overlay.
