Abstract
A disk drive suspension circuit has copper signal conductors connected by vias through an insulative layer to respective stainless steel flying leads. The stainless steel flying leads are activated and plated with one or more metals, with a final layer over the flying lead being a layer such as gold, suitable for bonding to form bond pads. The gold bond pads may be attached using thermosonic welding, solder ball bonding, or other suitable methods to an electrical component such as wires or a the disk drive's pre-amp circuit.
