Problems solved by technology

However, the etching process and the use of chemical solvents to clean the fixture will damage the adhesion performance of the fixture surface, thereby reducing the adhesion strength of the dry film layer on the fixture surface, thereby reducing its heat transfer efficiency
Therefore, the low adhesion performance between the dry film layer and the fixture and the low heat transfer efficiency will cause the strips to be burned during the etching process, thereby damaging the strips and reducing their yield

Abstract

The invention discloses a long bar processing method, which comprises the following steps: (1) providing a fixture, wherein the fixture is provided with an upper surface matched with the long bar; (2) forming a heat conduction layer on the upper surface; (3) forming a dry film layer on the heat conduction layer; (4) splicing the long bar to the fixture, and causing one surface of the long bar to be fit with the dry film layer; and (5) etching the long bar. The method has the advantage of high heat conduction efficiency, the long bar can be prevented from being burnt in an etching process. The invention also discloses a long bar processing device.

Description

technical field [0001] The invention relates to the field of information recording disk drives, in particular to a method and device for processing elongated bars in the manufacturing process of magnetic heads. Background technique [0002] A magnetic disk drive is a common information storage device and generally includes a plurality of rotating magnetic disks mounted on a spindle motor for storing data and magnetic heads for reading data from or writing data to the magnetic disks. People have higher and higher requirements on the capacity of the magnetic disk drive. Although increasing the magnetic track recording density of the magnetic disk can increase the capacity of the magnetic disk drive, the performance of the magnetic head needs to be improved accordingly so that it can be positioned on the magnetic track more precisely. The magnetic head is the core component of the magnetic disk drive, and its flight characteristics largely determine the read and write performan...
