Abstract
The invention discloses an assembling method of mini hard disk head component, which comprises the following steps: proceeding the antistatic preparation; fixing the mini hard disk base through chuck; extracting the head component through head component extractor; releasing the soft circuit board; fixing the soft circuit board of head component on the hard disk base through torque screwdriver; cleaning the screw head; fixing the head driving bearing on the hard disk base; dividing the mini hard disk component extractor and head; making the head separator to turn the head at the ring road position into the track; detaching the mini hard disk base of head component. The invention can prevent the screw assemblage from physical damage of head, which protects the head component from antistatic damage, physical damage and dust.
Description
Technical field:
The present invention relates in a kind of mini-hard disk production run the installation method of small-sized hard disk magnetic head assembly.
Background technology:
Head stack is the main element of mini-hard disk, and it is made up of magnetic head, head arm, soft-circuit board, magnetic head driving bearing, and wherein magnetic head is one of main element of controlling disk read-write, but it is very easily impaired, comprises physical damnification, electrostatic discharge damage equivalent damage.Magnetic head in the past reads in the production run of series products; tool and method used when head stack is installed is often not enough to the protection of small-sized hard disk magnetic head assembly; cause easily the head stack static discharge damage (because of the magnetoresistive head operating power of mini-hard disk bigger; susceptibility to static discharge is also just bigger), also have the pressure of screwdriver furbuckles generation and the physical damnification that grit can cause soft-circuit board and magnetic head.The method that other series products head stack therefore was installed in the past is inapplicable to the installation of mini-hard disk magnetoresistive head, needs a kind of installation method at the type hard disk head component, improves existing field engineering.
Summary of the invention:
The objective of the invention is to, a kind of small-sized hard disk magnetic head assembly mounting method is provided.The protection head stack is not subjected to electrostatic discharge damage and physical damnification in the head stack installation process.
The present invention constitutes small-sized hard disk magnetic head assembly mounting method like this.This method comprises the steps;
A, operator wear electrostatic prevention conjoined clothes, gloves by standard, and wind is bathed then, has worn ESD-preventive wrist strap and has guaranteed that wrist strap ground connection is good;
B, usefulness mini-hard disk base clamp be the mini-hard disk pedestal fixedly;
C, open the vacuum equipment that connects head stack extraction apparatus vacuum suction interface 1 and 2, hold the soft-circuit board 6 of magnetic head driving bearing 7 and head stack, extract head stack with the head stack extraction apparatus;
D, elder generation clean the moment of torsion driver bit with moment of torsion driver bit clearer, close the vacuum equipment that links to each other with vacuum suction interface 2, discharge soft-circuit board, extract a screw with the moment of torsion screwdriver then head stack soft-circuit board 6 is fixed on the hard disk pedestal;
E, the screw terminal that fixes is cleaned with Hoover;
F, earlier with moment of torsion driver bit clearer to moment of torsion driver bit cleaning, a screw that extracts another specification with the moment of torsion screwdriver is fixed on head stack magnetic head driving bearing 7 on the small harddisk pedestal from the hard disk pedestal back side then;
G, the screw terminal that fixes is cleaned with Hoover;
H, close vacuum suction interface 1 separately, use the magnetic head separation vessel that magnetic head is forwarded to the ring road position and enters the ring road track small-sized hard disk magnetic head assembly extraction apparatus and head stack;
I, from the mini-hard disk base clamp, lay down the mini-hard disk pedestal that installs head stack, small-sized hard disk magnetic head assembly installs.
Owing to adopted such scheme; has only small-sized hard disk magnetic head assembly extraction apparatus contact small-sized hard disk magnetic head assembly in the whole process; the people does not directly contact small-sized hard disk magnetic head assembly; so guaranteed the safety of small-sized hard disk magnetic head assembly; played the effect of anti-electrostatic-discharge; the pressure that utilizes vacuum to produce holds soft-circuit board and magnetic head driving bearing; when preventing from screw is installed to the physical damnification of head stack; and use suction cleaner to remove issuable grit, so the present invention have the protection head stack and is not subjected to electrostatic discharge damage and physical damnification; remove the advantage of grit.
