Lower clamp/# - (4% introduced the sanding tool d in this order.In order to sand, the lower clamper C clamps the sanding wire e, and no tension is applied. Then, it descends together with the lower crank z4-c of the sanding tool I, leads out the tip of the bonding wire e to the pad of the pellet f, and crimps it, and then performs all the sanding on the f side of the Benz f.

By the way, when gluing the pellet f and lead frame g, 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 19 is best for this tension.

However, the lower clamp i+-c, which applies tension, has conventionally used a solenoid to control the clamping force;
There is a problem in that it is very difficult to apply a tension of one leg to the bonding wire e by applying a clamping force of about 1/1, and the tension is unstable. In particular, the higher the bonding tool is, the greater the drawbacks become. For this reason, there are many problems such as loop curl, where the bond wire loop curls, and defects caused by variations in wire loop height, such as edge touch caused by shortening the loop length, and yields are significantly reduced. There is a need for something that can solve these problems.

That is, 11 in the figure is a tube body. This pipe body 1 is the third
As shown in detail in the figure, the sanding wire 2 has an inner diameter larger than the diameter of the sanding wire 2, and the roller body 1 is inserted into the lower part of the outer periphery.
2 is provided with a tube body 11m made of glass, for example. This tubular body 11 is connected to a dangling wire 10.
The roller body 12 is inserted in the lower part of the body so that it can be freely inserted into the body. In addition, an outlet portion 13 is provided within the peripheral wall of the tube body 11.
An air guide path 13 is formed in which a portion a opens toward the wire feeding portion 1 side with respect to the inner cavity of the tubular body 11, and an inlet portion 13b communicates with the above-mentioned roller body 12. and,
An air supply source 15 such as a fan is connected to the input roller body 12 via a wind speed controller 14'Jk, and air is supplied from the air supply source 15 to the wind speed controller 14, the input roller body 12, the air guide path 13, and the inside of the tube body 11. Air can be blown out around the winding wire 7 through the cavity. However, around the danding wire 7, a uniform tension can be applied to the danding 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 so that a stable tension of about 1 g can be applied. It has become. Note that both ends of the tubular body 11 are bent to form curved surfaces so that the bonding wire 7 will not be accidentally touched by the blown air.

With the sanding wire 7 fully clamped by the lower clamper 4 and with no tension applied, the canting tool 5 is lowered together with the lower clamper 4 to lead out the tip of the rf sanding wire 7 to the butt of the pellet 8. Crimp. As a result, the dangling wire 7 is joined to the pellet 8 by the frictional heat generated by the ultrasonic vibration on the binding tool 5 side. Then, the lower clamp '1'-4 is released, and the tensioning mechanism 2 applies tension to the binding wire 7. Here, the tension is determined by the wind speed,
This is done by operating the speed controller 14 and air supply source 15 when the air volume is set. That is, at the same time as the clamp is released, the air supply source 15 first passes the wind speed control roller 14 to the input roller body 1.
2 are blown out into the air guide path 13. Then, most of the air is blown out from the inlet 7Jb of the air guide path 13 into the inner cavity of the tube body 11, around the sanding wire 10, and toward the wire feeding section 1. At this time, a uniform tension is applied to the bonding wire 7. Note that a breeze is also blown out from the opening of the tubular body 11 on the side of the landing tool S to prevent the dangling wire 7 from adhering to the tubular body 11 due to static electricity.

After that, the work stage (not shown) is moved, and the leads of the lead frame 9 are moved to the canting tool 5.
If you guide the sanding wire 7 to the tip of the sanding wire 7 and apply tension at this position, press the sanding wire 7 with the descending motion of the 1c & bending tool 5 and the lower clamp or -4. is joined to the lead frame 9. And then, divide the total tension by % and lower the clamp? -4, yW The bonding tool 5 is raised and the bonding wire 1't- is cut, thereby making a connection between the pellet 8 and the lead frame 9.

In this way, the tension of the danding wire 7 can be controlled without variation because the air flow gives a uniform tension to the danding wire 7 without any contact with the danding wire 7, which would cause instability. This makes it possible to always give a stable tension to p1.

Therefore, the height of the wipe loop formed between the pellet 8 and the lead frame 9 can be a stable height that does not cause under-loops, loop curls, edge touches, etc., and a stable and good wipe loop can be obtained. can be formed, and can guarantee an assembly of excellent quality. It is particularly effective for increasing bonding speed. Moreover, since air flow is the main component, precision is not required, and there is an advantage in terms of cost.

This is effective for things that increase speed. Moreover, since air flow is the main component, precision is not required, and there is an advantage in terms of cost.
