Abstract
A disk drive head suspension including a load beam having a load beam load point region and a flexure, attached to the load beam, having a flexure load point region. A mass of viscoelastic material is fixedly attached to both load beam load point region and flexure load point region to form a pinned load point. A method for manufacturing a disk drive head suspension of the type having a flexure with a flexure load point region on a load beam with a load beam load point region. The flexure load point region is spaced apart from the load beam load point region. A load point is formed by applying a mass of viscoelastic material to the load point region of at least one of the flexure and the load beam.
