になつている。 Conventionally, as shown in FIG. 1, this type of wire bonding apparatus has a wire feeding section a, an upper clamp b as a tension mechanism, a lower clamper c as a clamper mechanism, and a bonding tool d arranged in this order from the upper side. The tip of a bonding wire e fed out from a wire feeding part a is introduced into an upper clamper, a lower clamper c, and a bonding tool d in this order. When bonding, the bonding wire e is clamped by the lower clamper c, and with no tension applied, the bonding tool d is lowered together with the lower clamper c to clamp the tip of the bonding wire e onto the pellet f. The pellet is led out to a pad and crimped, and here bonding is first performed on the pellet f side. Next, the lower clamper c is released from the clamp, and the upper clamper applies tension to the bonding wire e to release the pellet f.
The work stage (not shown) on which the lead frame g is mounted is moved, and the lead (not shown) of the lead frame g on the work stage is guided to the tip of the bonding tool d, and while applying tension at this position, the lead of the bonding tool d is moved in the same way. and lower clamper c
If the bonding wire e is crimped by the operation of , and then the bonding wire e is pulled off by the clamping and lifting of the lower clamper c, the connection between the pellet f and the lead frame g is made through the wire loop. ing. However, it is possible to bond between the pellet f and the lead frame g based on the vertical movement of the bonding tool d, the clamping movement of the lower clamper c, and the tension applied by the upper clamper.

When bonding, it is important for quality to always form a good wire loop. For this purpose, it is necessary to always apply a constant tension to the bonding wire e. In particular, it is said that a force of about 1 g is best for this tension.

いる。 However, the lower clamper c that applies tension has conventionally used a solenoid to control the clamping force, but such a solenoid is used to constantly apply a clamping force of about 1 g to maintain a constant tension on the bonding wire. There is a problem that it is very difficult to give a tension e, and that the tension is unstable. In particular, the higher the bonding speed, the greater the drawbacks. For this reason, when bonding, it is important to avoid such problems as under-loops and loop curls, where the wire loop hangs down due to the long loop length, and edge-touching, which occurs when the loop length becomes short. There is a need for something that can solve these problems, which tend to cause many defects due to variations in the height of the wire loops, resulting in a significant drop in yield.

ことができるようになつている。[Embodiment of the Invention] The present invention will be described below based on an embodiment shown in FIGS. 2 and 3. Figure 2 shows a wire bonding device, in which 1 is a wire feeding section;
2 is a tension mechanism, 3 is a guide plate, 4 is a lower clamper constituting a clamper mechanism, and 5 is a bonding tool equipped with an ultrasonic vibrator (not shown). Each of these devices is attached to the bonding head main body 6 in order from the upper side. The lower clamper 4 and the bonding tool 5 are attached via a lifting mechanism (not shown), so that they can be moved up and down in synchronization with each other. The tip of the bonding wire 7 such as gold wire or aluminum wire fed out from the wire feeding section 1 is connected to the tension mechanism 2, the guide plate 3, the lower clamper 4, and the bonding tool 5.
Based on the vertical movement of the bonding tool 5, the clamping movement of the lower clamper 4, and the tension of the tension mechanism 2, the parts of the pellet 8 mounted on the work stage (not shown) and the leads of the lead frame 9 are can be bonded using the bonding wire 7 using frictional heat.

It is as follows.

成している。 That is, 11 in the figure is a tube body. This tube 1
As shown in detail in FIG. 3, the tube body 1 is made of, for example, a glass tube body 11a having an inner diameter larger than the diameter of the bonding wire 7 and having an inlet port 12 on the lower side of the outer periphery. This tubular body 11 is inserted into the bonding wire 10 so that it can be freely inserted into the bonding wire 10, with the inlet mouth body 12 disposed below the bonding wire 10. Further, within the circumferential wall of the tube body 11, an annular outlet portion 13a extending in the circumferential direction of the tube body 11 opens toward the wire feeding portion 1 side with respect to the inner cavity of the tube body 11, and an inlet portion 13b opens toward the wire feeding portion 1 side. An air guide path 13 communicating with the inlet port body 12 is formed. An air supply source 15 such as a fan is connected to the inlet port body 12 via a wind speed controller 14 .
Air (gas) can be blown out in an annular manner around the bonding wire 7 through the inlet port body 12, the air guide path 13, and the inner cavity of the tube body 11. However, around the bonding wire 7, a uniform tension can be applied to the bonding wire 7 by the flow of air introduced toward the wire feeding portion 1 side.
That is, the air guide path 13, the wind speed controller 14, and the air supply source 15 constitute an air introduction means, and the wind speed controller 14 and the air supply source 15 control the wind speed and air volume to provide a stable tension of about 1 g. It is now possible to do so. Note that both ends of the tubular body 11 are bent to form curved surfaces so that the bonding wire 7 is not inadvertently damaged by the blown air.
つぎにこのように構成されたワイヤボンデイン
グ装置の作用について説明する。 Next, the operation of the wire bonding apparatus configured as described above will be explained.

11に対する付着を防止している。 When the bonding wire 7 is clamped by the lower clamper 4 and when no tension is applied,
The bonding tool 5 is lowered together with the lower clamper 4 to crush the tip of the bonding wire 7 into a pellet 8.
Lead it out to the part and crimp it. As a result, the bonding wire 7 is bonded to the pellet 8 by the frictional heat generated by the ultrasonic vibration on the bonding tool 5 side. Next, release the clamp of lower clamper 4,
Further, the tension mechanism 2 applies tension to the bonding wire 7. Here, the tension is determined by the wind speed controller 14 in which the wind speed and air volume are set in advance.
This is done by activating the air supply source 15. That is, at the same time as the clamp is released, the air is first blown from the air supply source 15 through the air speed controller 14 and into the air guide path 13 from the inlet port body 12. Then, the wind flows through the entrance section 1 of the air guide path 13.
Bonding wire 1 from 3b to the inner cavity of tube body 11
Most of the wire is blown out toward the wire feeding section 1 around the wire 0. At this time, bonding wire 7
A uniform tension is applied to the Note that a breeze is also blown out from the opening of the tube 11 on the bonding tool 5 side to prevent the bonding wire 7 from adhering to the tube 11 due to static electricity.

なわれる。 After that, the work stage (not shown) is moved, and the lead of the lead frame 9 is guided to the tip of the bonding tool 5, and while tension is applied at this position, the bonding is performed by lowering the bonding tool 5 and the lower clamper 4 in the same manner. When the wire 7 is crimped, the bonding wire 7 is bonded to the lead frame 9 by frictional heat caused by ultrasonic vibration. Thereafter, the tension is released, the lower clamper 4 and the bonding tool 5 are raised, and the bonding wire 7 is cut off, thereby establishing a connection between the pellet 8 and the lead frame 9.

定した張力を与えることができるのである。 In this way, the tension of the bonding wire 7 can be controlled without variation because a uniform tension is applied to the bonding wire 7 by the air flow without any contact with the bonding wire 7, which would be an unstable element. It is possible to always provide stable tension.

It is possible to form a stable and good wipe loop, and it is possible to guarantee an assembly with excellent quality. It is particularly effective for increasing bonding speed. Moreover, since air flow is the main
Precision is not required, and it has the advantage of being superior in terms of cost. Moreover, bonding wire 7
Since air is blown out in an annular shape around the tube body 11, the bonding wire 7 is prevented from adhering to and rubbing against the tube body 11 due to static electricity, and the bonding wire 7 is prevented from being affected by the tension caused by the adhesion and further due to the friction.

防ぐことができる。 Therefore, it is possible to stably control the tension of the bonding wire, which is difficult, and to form a stable and good wire loop at all times. It is particularly effective for increasing bonding speed. Moreover, since the main component is gas flow, precision is not required, and it has the advantage of being superior in terms of cost. Furthermore, the annular air flow blown out around the bonding wire prevents the wire from adhering to and rubbing against the pipe body due to static electricity, and prevents the wire from being cut due to the effects of tension due to adhesion and furthermore due to friction. can be prevented.
