Abstract

A soldering device which form the electrical weld in the disk driving unit, including a bond head, a laser unit, a compressive gas supply, a welding bead supply. The bond head consists of a main channel and two sub-channel shells which connect with the main channel; the laser unit can emit the laser beam to pass through the main channel; the compressive gas supply provides the compressed gas to pass through one sub-channel and enter the main channel; the welding bead supply sends a single welding bead to pass through another sub-channel and enter the main channel; there is a cone structure in the main channel, which maintains the welding bead in the main channel and allow the laser beam from the laser unit to affect the welding bead before the welding bead releases from the bond head by the compressing gas.

Description

technical field [0001] The invention relates to a disk drive unit, in particular to a welding device and a method for forming electrical welding in the disk drive unit. Background technique [0002] A magnetic disk drive is a common information storage device that uses a magnetic medium to store data and a movable head assembly placed over the magnetic medium for selectively reading data from the magnetic medium or writing data to the magnetic medium. medium. [0003] Figure 1-2 A typical disk drive unit 10 including a motor base assembly 12 , cover 14 and printed circuit board assembly 16 is depicted. As mentioned above, the motor base assembly 12 includes a magnetic head 20 (see image 3 ), a magnetic head suspension assembly (head stack assembly) 18, a magnetic disk 22 mounted on a spindle motor 24 for rotating the magnetic disk, and a motor base 26 for accommodating the above-mentioned components. The magnetic head 20 runs at high speed on the surface of the magnetic...
