Abstract:
1. A disk drive suspension comprising: a stainless steel mount plate, the mount plate being electrically grounded, the mount plate having a first and flat portion thereof that has been chemically activated; a gold bond pad plated onto the chemically activated portion of the mount plate, and gold not being plated so as to substantially cover any swage hub of the mount plate; and a piezoelectric microactuator, the piezoelectric microactuator having first and second metallized surfaces thereof; wherein: the first metallized surface of the microactuator is electrically connected to a microactuator driving voltage; the second metallized surface of the microactuator is electrically and mechanically bonded to the gold bond pad on the stainless steel mount plate via conductive adhesive; and the microactuator is electrically grounded through the conductive adhesive, the gold bond pad plated onto the chemically activated portion of the mount plate, and the mount plate.
