ABSTRACT:
A head gimbal assembly includes a suspension of the type supporting a slider and a flex circuit. The suspension is formed of a load beam that supports the flex circuit, and a resilient flexure which is secured to the load beam and which supports the slider. The flex circuit is comprised of conductive traces formed on a compliant, dielectric substrate. The substrate includes a body portion and a head portion for supporting the conductive traces. The substrate head portion is patterned such that selected portions of the head portion are removed to leave bare conductive trace sections, and to achieve reduced pitch and roll stiffness of the flex circuit. The flex circuit can optionally include a thin seed layer formed on the underside of the substrate to reduce static charge buildup.
