Abstract
A head gimbal assembly includes a slider, a flexure, and a plurality of solder receptacles. The slider has an air-bearing surface and a metallized backside opposite the air bearing surface. The flexure includes a flexure tongue layer at least partially formed of stainless steel. The flexure further includes at least one additional layer over the flexure tongue layer. The plurality of solder receptacles extend through the at least one additional layer to the flexure tongue layer. Solder fills at least one of the solder receptacles and contacts the stainless steel of the flexure tongue layer.
