Abstract
An integrated lead flexure comprising a base region, a gimbal extending from the base region and conductive traces. The gimbal includes spring arms and a slider mounting region extending from the spring arms. The conductive traces include one or more unsupported trace sections extending from head bond pads on the slider mounting region to the base region off of the spring arms. One or more metal islands on the unsupported trace sections enhance the impedance characteristics of traces. An insulating layer is located between the traces and the metal islands.
