Abstract
An integrated lead head suspension flexure includes a mounting region, a gimbal extending distally from the mounting region and having bond pads, and a tail extending proximally from the mounting region and having terminal pads. First trace sections having a first structural configuration, such as interleaved traces, are electrically connected to the terminal pads and extend across the tail and mounting region. Second trace sections having a second structural configuration different than the first structural configuration, such as ground plane traces, are electrically connected to the bond pads and extend across the gimbal. Transition structures electrically connect the first trace sections to the second trace sections. The first and second trace sections impedance match the different impedances at the bond pads and terminal pads.
