Abstract

PURPOSE:To simplify a device and improve productivity by forming a stage so as to be smaller than the window of a clamper. CONSTITUTION:A stage 6 which positions and mounts a semiconductor pellet 5 is loaded on an XY table, and formed so as to be smaller than the window 4a of a clamper 4. That is, since the stage 6 is smaller than the window 4a of the clamper, it can be opened and shut without making the stage 6 ascend and descend. By making the interval between a bond guide 3 and the stage 6 keep a specified size, suitable stress can be applied to a lead 1 only by pressing pressure of the lead 1 as the result of descending of a tool 7, without making the bonding guide 3 and the clamper 4 ascend, and thus the forming is enabled. Thereby the device can be simplified and the productivity can be improved.

[Prior Art] A conventional tape bonding device is disclosed in, for example, Japanese Patent Application Laid-open No. 1983-
As shown in Japanese Patent No. 15433, with the tab tape clamped by the bond guide and clamper, the tool is lowered and the stage storing the semiconductor pellet is raised, and the lead of the tab tape is pressed against the semiconductor pellet by the tool to bond. Further, as described above, when the tool presses the lead against the semiconductor pellet, both the bond guide and the clamper are moved upward to form the lead.

[Problems to be Solved by the Invention] In the above-mentioned prior art, lead forming is performed by moving both the bond guide and the clamper upward, and therefore a vertical movement mechanism is required for this purpose, making the device expensive. Another problem is that productivity is poor because it is necessary to raise the bond guide and clamper after pressing the lead onto the semiconductor pellet with a tool, and it is necessary to open the clamper after the stage is lowered. was there.

[Example] An example of the present invention will be described below with reference to FIGS. 1 to 3. A bond guide 3 that guides the tab tape 2 provided with the lead 1 to the bonding position is formed with a window 3a having almost the same shape as the opening 2a of the tab tape 2.
The lower surface of the bond guide 3 in the vicinity of the bonding position has a flat part 3b. The clamper 4, which is moved up and down (opened and closed) by an opening/closing means (not shown), has a flat part 3b that has a shape that is almost the same as the opening 2a of the tab tape 2, and has a flat part 3b. A window 4a is formed which is the same as or larger than the opening 2a, and a clamper 4a is formed.
is made of a material with a small coefficient of thermal expansion, such as Invar material. The stage 6 on which the semiconductor pellet 5 is positioned and mounted is mounted on an xY table (not shown), and is formed smaller than the window 4a of the clamper 4. Further, the height of the upper surface of the stage 6 is adjusted to be kept at a constant distance from the lower surface of the bond guide 3 in order to form the leads 1. In addition, in the figure, 7 indicates a tool.

Next, the effect will be explained. As shown in FIG. 1, with the clamper 4 in an open state, the tab tape 2 is fed by a feeding mechanism (not shown), and the leads 1 provided on the tab tape 2 are positioned at the bonding position. Thereafter, the clamper 4 is closed as shown in FIG. On the other hand, the semiconductor pellet 5 positioned on the stage 6 is waiting at the bonding position. Then, a positional deviation between the lead 1 and the semiconductor pellet 5 is detected by a detection means (not shown), and the stage 6 is moved in the XY force direction, and the lead 1 and the semiconductor pellet 5 are moved.
electrodes are aligned.

Next, as shown in FIG. 3, the tool 7 is lowered to
is pressed down to press the lead 1 to the electrode of the semiconductor pellet 5 for bonding. In this case, the tab tape 2 is held between the bond guide 3 and the clamper 4, and in this state, the lead 1 is pushed down, so the tool 7 rises to form the lead 1, and the clamper 4 opens, and the tab tape 2 is fed one pitch so that the next device part (lead 1 part) is located at the bonding position. Thereafter, the series of operations described above are repeated in sequence.

In this way, since the bond guide 3 is formed flat, the tab tape 2 can be fed horizontally, the leads 1 are not bent, and the bonding position of the leads 1 is stable.

Further, since the window 4a of the clamper 4 is larger than the opening 2a of the tab tape 2, when the lead l is pushed down by the tool 7, the lead 1 does not come into contact with the edge of the window 4a of the clamper 4. The lead 1 is not damaged, and the window 4a of the clamper 4 and the window 3a of the bond guide 3 are formed in almost the same shape as the opening 2a of the tab tape 2.
The tab tape 2 portions for all the leads 1 are clamped evenly, and bonding is performed in a stable state.

Also, since the stage 6 is smaller than the window 4a of the clamper 4,
The clamper 4 can be opened and closed without moving the stage 6 up and down. In addition, by keeping the distance between the bond guide 3 and the stage 6 at a predetermined dimension, the lead 1 can be properly pressed by only pressing the lead 1 by lowering the tool 7, without raising the bond guide 3 and the clamper 4. Stress is added and 7 ohms are applied.

[Effects of the Invention] As is clear from the above description, according to the present invention, since the stage is smaller than the window of the clamper, the clamper can be opened and closed without moving the stage up and down. In addition, by keeping the gap between the bond guide and the stage at a predetermined dimension, the lead can be formed by applying appropriate stress just by pressing the lead by lowering the tool, without raising the bond guide or clamper.
