A hard disk drive head slider housing a read-write transducer includes a plurality of electrical connection pads, where each electrical pad includes an interconnection portion configured for electrically connecting to an interconnected component, such as a lead suspension, a probe contact portion configured for electrical testing the head slider, and at least one slit positioned between the interconnection portion and the probe contact portion, thereby physically distinguishing and separating the two portions of a multiple-portion pad to inhibit undesirable solder flow to the wider probe contact portion on the slider side of each pad. A more controlled solder joint is provided, while the probe contact portion can remain relatively wide for probe contact and the interconnection portion can remain relatively narrow to reduce solder bridges among the pads.
