METHOD OF MANUFACTURING LAMINATED STRUCTURE FOR DISK DRIVING SUSPENSION ASSEMBLY AND LAMINATED STRUCTURE FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of making manufacturing efficiency higher and a product cost lower than the conventional production process, etc., utilizing only the dry etching process represented by plasma etching in molding an intermediate second layer consisting of an electrically insulating material in a method of manufacturing a laminated structure for a disk driving suspension assembly using a multilayered lamination sheet having a first layer consisting of a metallic spring material, the second layer described above and a third layer consisting of a conductive material. SOLUTION: The method of manufacturing the laminated structure for the disk driving suspension assembly comprising using the multilayered lamination sheet having the first layer 50 consisting of the metallic spring material, the intermediate second layer 90 consisting of the electrical insulating material and the third layer 70 consisting of the conductive material and performing the dry etching process after wet etching as a process step of molding the second layer 90 and the laminated structure thereof are provided.
