LAMINATE FOR HDD SUSPENSION AND PROCESS FOR PRODUCING THE SAME

摘要

The subject of the present invention is to provide a laminate for an HDD suspension which has a thin conductive layer and is free from warpage (camber) or deformation and that in compliance with demands on an HDD suspension for realization of a high density and superfine wiring, ensures high reliability and high precision; and a production process for the same. There is provided a laminate for an HDD suspension containing a stainless layer, polyimide resin layer and conductive layer, wherein a thickness of the conductive layer is 10 mum or less, and in the production process, a laminate containing a stainless layer/polyimide resin layer/conductive layer is produced using the conductive layer having a thickness of larger than 10 mum, and then only the conductive layer is subjected to chemical etching to thereby reduce a thickness of the conductive layer to 10 mum or less.
