Abstract
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.
