description A suspension includes a flexure including a conductive substrate, and a dielectric layer formed on the conductive substrate, and the conductive substrate being grounded; and a plurality of electrical traces formed on the dielectric layer and extending from a leading portion to a trailing portion of the flexure, and the electrical traces at least having a pair of read traces. At least one via is formed at certain position on the read traces to connect the read traces with the conductive substrate that is etched partially. It can minimize ESD damage during various stages of manufacturing process of the disk drive unit, reduce manufacturing cost, and also improve electrical performance of the suspension interconnection.
