摘要： A disk drive head suspension flexure having a gimbal region and a tail includes a metal base layer, an insulation layer over the base layer and two or more pairs of adjacent traces extending over the insulation layer from the gimbal region to the tail. Each trace includes terminals on the gimbal region and tail. Two or more conductive metal signal transmission planes are embedded within the insulation layer and extend from the gimbal region to the tail between the pairs of traces and metal base layer. Each of the embedded signal transmission planes has a width extending across a width of a pair of the traces. Terminals on the gimbal region and tail are coupled to the signal transmission planes by connection vias extending through the insulation layer.

摘要： 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.

摘要： An integrated lead head suspension component comprising a spring metal layer, a first conductor layer, a first dielectric layer between at least portions of the spring metal and the first conductor layers, a second conductor layer and a second dielectric layer between at least portions of the first and second conductor layers. The head suspension component includes stacked traces having first and second traces in the first and second conductor layers, respectively. The stacked traces comprise base sections having first widths and gimbal sections having second widths that are less than the first widths. The second dielectric layer can have a generally constant thickness on the base and gimbal sections or, alternatively, a gimbal section thickness that is less than a base section thickness.

摘要： A method for manufacturing an integrated lead suspension component. One or more first conductive ground planes are formed on a stainless steel base layer. One or more second conductive ground planes, including portions on the surface of the first conductive ground planes, are formed at void portions and backed portions of the stainless steel base layer. The material of the second conductive ground planes is non-reactive to a first etchant. An insulating layer is formed on the second ground planes on the side opposite the stainless steel base layer and on the stainless steel base layer. Traces are formed on the insulating layer. Voids are formed in void portions of the stainless steel base layer using the first etchant and the second conductive ground planes at the void portions as etch stops.
