Abstract:
A method of manufacturing an integrated lead head suspension flexure of the type having conductors on a spring metal layer capable of being etched by a first etching process. The method includes forming a patterned layer having gaps one or more flying lead regions of dielectric material on a major surface of the spring metal layer and forming one or more conductive leads on the flexure, including onto the dielectric material and over exposed spring metal at the gap at each flying lead region. At least the flying lead portion of the conductive lead is formed from conductive material resistant to the first etching process. The method also includes etching a flying lead region of the spring metal layer to remove a portion of the spring metal layer in the flying lead region and expose the flying lead portions of the conductive lead.
