Patent ID: 7986494

Claim:
An integrated lead flexure for a disk drive head suspension, the integrated lead flexure comprising: a spring metal base layer; an insulating layer over the spring metal base layer; a plurality of terminal connector pads; a plurality of head connector pads; a first integrated transmission line array including a first plurality of spaced-apart traces electrically insulated from one another by the insulating layer and extending together along a first transmission pathway between the terminal connector pads and the head connector pads and including a first transmission line array segment and a second transmission line array segment, the first transmission line array segment having a taper in trace spacing to define substantially continuously decreasing trace spacing and the second transmission line array segment having a taper in trace spacing to define substantially continuously decreasing trace spacing, the first and second transmission line array segments having different tapers in trace spacing such that multiple different impedance tapers are exhibited along the transmission line array and the first integrated transmission line array exhibits a different characteristic impedance at the terminal connector pads than at the head connector pads.
