Abstract

PURPOSE:To prevent entwinement and entanglement of a fine wire and to enable the smooth feed of a fine wire, by a method wherein a bobbin around which the fine wire is wound is immersed in liquid, and by pulling the fine wire in the direction of the axis of the bobbin, the fine wire is unwound. CONSTITUTION:When a metallic wire 2 is pulled upward, the metallic wire 2 wound around a bobbin 1 is unwound as it is disentangled. In this case, since the metallic wire 2 is braked by means of viscosity of pure water 12 and is kept in a state where proper tension is normally applied, entangling of the metallic wire 2, equivalent to some full rounds around the bobbin, at one time or drop of the metallic wire from the bobbin 1 is prevented from occurring. Thus, since entwinement and entanglement are difficult to occur the metallic wire 2 and besides so high tension is not exerted on the metallic wire 2 even if the unwinding speed of the metallic wire 2 is increased, the smooth feed of the metallic wire is practicable at any unwinding speed throughout a range of from a low speed to a high speed.

``Prior art'' When feeding gold wire wound around a bobbin to an IC wire bonding device, etc., the bobbin 1 is held upright as shown in Figure 2, and the gold wire 2 is pulled upward and fed out. A new method is adopted, but if left as is, the gold wire 2 will become slack.
To prevent the wound gold wire 2 from slipping off, conventionally, as shown in Fig. 3, short resin threads 3 are attached radially around one end of the bobbin L, and the elasticity of the threads 3 causes the gold wire 2 to be properly Alternatively, as shown in Fig. 4, the bobbin 1 may be placed on a rotary table (as shown in the diagram) and rotated according to the processing speed of the wire bonding machine.
I try to bring out the .

[Problems to be Solved by the Invention] However, in the method shown in Fig. 3, the gold wire 2 hits the resin threads 3 one after another under tension, so that a slight amount is left on the surface of the gold wire 2. It is inevitable that scratches will occur, and such scratches may cause wire breakage in the wire bonding process. Further, since the gold wire 2 is fed out along the circumferential surface of the bobbin 1, the wound gold wire 2 may be lifted and tangled. Furthermore, when the feeding speed of the gold wire 2 changes, the resin thread 3
Since the tension applied by the wire changes, the thickness of the resin thread 3 must be changed each time.
On the other hand, in the method shown in FIG. 4, an accurate control device is required to match the feeding speed of the gold wire 2 and the rotational speed of the rotary table. The disadvantage was that the equipment cost was high.

Reference numeral 10 denotes a cylindrical liquid tank with a bottom, and in the center of the liquid tank 10, a bobbin 1 around which a gold wire 2 is wound is arranged upright. A disk-shaped bobbin cover 11 is attached to the upper surface of this bobbin cover. This bobbin cover 11
The edges are rounded so that even if the gold wire touches it, it will not get scratched. Then, pure water 1 is poured into the liquid tank 1θ until the bobbin cover 11 is sufficiently submerged.

A circular II)7 opening 14 is formed in the center of the lid 13, and the gold wire is guided through this opening 14 to a wire bonding device (not shown). Note that the periphery of the opening 14 of this lid 13 is rounded, and the gold wire 2
Even if it touches the lid 13, it will not be damaged.

Next, the action will be explained. When the wire bonding device is operated and the gold wire 2 is pulled upward, the gold wire 2 wound around the bobbin 1 is unraveled one after another and is fed out. At this time, the gold wire 2 is braked by the viscosity of water and is always kept under a moderate tension, so that several rounds of the gold wire 2 on the bobbin may unravel at once or fall off the bobbin L. Never.

Therefore, according to this method of supplying the gold wire, the gold wire 2 does not become tangled or tangled (in addition, even when the feeding speed of the gold wire 2 increases, very large tension is not applied to the gold tQ2, so Gold wire can be fed smoothly at any feeding speed from low to high.

Further, since the gold wire 2 is fed out underwater and rarely comes into contact with solid objects, the surface is not scratched, and the risk of wire breakage etc. in the wire bonding process can be reduced.

Furthermore, since the gold wire 2 is fed out through pure water 12, dirt and dust attached to the gold wire can be removed.

In addition, although pure water was used in the above example, in addition to the amount of water,

In addition, by adding a highly viscous liquid such as glycerin or oil, or by using a solution containing an appropriate substance as necessary, the viscosity of the liquid can be adjusted according to the feeding speed and the thickness of the gold wire. The position of the bobbin l is not limited to the upright position, but may also be arranged in an inclined position in the liquid.

さらに、本発明が適用される細線は、金線に限らない。Furthermore, the thin wire to which the present invention is applied is not limited to gold wire.
