Abstract
A gimbal and corresponding head suspension assembly including a planar flexure platform having integral static attitude compensation, nominal angle adjustment, and load point etched or etched-formed raised features. The head suspension assembly can also include a load point cover with etched or etched-formed load point features. The etched features are manufactured by masking a pivot point at about the intersection of the roll axis and the pitch axis, thus leaving a raised protuberance having either a pivot point or a load point feature. The process of manufacturing etched-formed features includes etching protuberances and slots. A punch press is then applied to the protuberances. The slots help control the formation of raised domes and provide additional static compensation and nominal angle adjustment pivoting clearance.
