    Abstract: A disk drive suspension assembly including an elongated polymeric base member having a plurality of traces formed directly on a first surface thereof and a reference voltage layer formed on a second surface thereof. A support member is formed directly on at least a portion of the reference voltage layer. The plurality of traces overlay at least a portion of the reference voltage layer. The reference voltage layer is formed from a first electrically conductive material and the support member is formed from a second electrically conductive material. The first electrically conductive material providing substantially greater electrical conductivity and substantially less tensile strength than the second electrically conductive material. The support member includes a head gimbal portion having a first thickness and a load beam portion having a second thickness. The second thickness is substantially greater than the first thickness.

    Abstract: A dielectric film for use as a substrate for a flexible circuit comprises a polymer selected from the group consisting of liquid crystal polymers and polyimide copolymers including carboxylic ester structural units in the polymeric backbone. The dielectric film has a thickness from about 25 μm to about 60 μm including at least one thinned, recessed region wherein the thickness is reduced to less than 15 μm, as required for use of the dielectric film in e.g. ink jet print head, hard disk drive head gimbal assembly and touch sensor applications.
