Abstract:
A method for manufacturing an integrated lead suspension for a hard disk drive, comprising:(a) providing a metal support layer, at least one dielectric layer, and at least one conductor layer; (b) forming a void in the support layer at a selected location; then (c) laminating the dielectric layer between the support and conductor layers to form a laminate; and then (d) etching the laminate of step (c) to form a lead suspension, wherein said void intentionally weakens a selected high strain area in the suspension to form a constraint damping layer; and wherein step (c) comprises laminating a second dielectric layer on a side of the support layer opposite said first mentioned dielectric layer, and a second conductor layer on said second dielectric layer to form a five layer laminate with the first and second conductor layers being on a top and a bottom of the five layer laminate.
