Abstract

PURPOSE:To remove the foreign matter such as dust by providing static electricity removing parts between a tape sending part and a punching part and between the punching part and a tape winding part, respectively. CONSTITUTION:The tape 1 carried from a tape sending part 2 is punched in a specified shape with the specified die at a punching part 3, after removing foreign matter such as adhering dust by blowing antielectrostatic ion shower with a static electricity removing part 5a beforehand, and the residue, etc. after extraction of the tape 1, which have adhered at this time, are removed by blowing antielectrostatic ion shower with an static electricity removing part 5b again, and the cleaned tape 1 is wound on a reel with a tape winder 4. By doing it this way, foreign matter such as dust do not adhere to the punched tape 1, so inferiority reduced, and yield rate improves sharply.

Description

[Detailed description of the invention] [Industrial application field] The present invention is directed to T A B (Ta1)e AIIqOIOt
(ed Bonding) tape press equipment.

Prior Art 1 FIG. 3 shows a conventional example of press equipment for TAB tape. As shown in the figure, TAB tape prepress equipment 'A8 tape (hereinafter referred to as tape) 1
The tape is conveyed to a punching and punching section 3 by a tape feeding section 2, and a predetermined shape is punched out using a die, and the tape 1 is wound up at a tape winding section 4.

[Problems to be Solved by the Invention J TAB tape is made of an organic insulating film material such as polyimide, and such insulating materials themselves tend to have static electricity, and they also tend to pick up static electricity in the surrounding environment or during the transportation process. It's easy to do. For this reason, in the above-mentioned conventional technology, foreign matter such as dust that has adhered to the TAB tape in advance cannot be removed as it is due to the presence of static electricity, so it adversely affects the pattern formation on the tape in the etching process in the post-process, etc. This causes serious defects such as lead connections, disconnections, protrusions, and pinholes, leading to a decrease in yield. In addition, when a predetermined shape is punched with a mold, the residue and surrounding dust also adhere between the punching part and the tape winding part, resulting in defects and lower yields. .

The present invention has been made in view of the above points, and it is an object of the present invention to provide prepress equipment for TAB tape that enables a significant improvement in yield. .

[Means for Solving the Problems] The above object is achieved by providing static electricity removal sections between the tape feeding section and the punching section and between the punching section and the tape winding section.

[Operation] Since the above means is provided, foreign matter such as dust is removed, and defects are reduced.

[Example] The present invention will be described below based on the illustrated example. FIG. 1 shows an embodiment of the invention. It should be noted that the same parts as in the prior art have been given the same reference numerals, so their explanation will be omitted.

In this embodiment, static electricity removing sections 5a and 5b are provided between the tape feeding section 2 and the punching section 3 and between the punching section 3 and the tape winding section 4, respectively. By doing this, foreign matter such as dust is removed, and defects are reduced, making it possible to significantly improve the yield of TAB.
Can be pre-press equipment for tape.

That is, the tape 1 conveyed from the tape feeder 2 is sprayed with an anti-static ion shower in the static electricity removal section 5a to remove foreign matter such as dust that has adhered in advance, and then punched into a predetermined shape with a die in the punching section 3. The tape 1 is removed, and the adhering scraps of the tape 1 are removed by spraying an antistatic ion shower again in the static electricity removal section 5b, and the cleaned tape 1 is wound onto a reel in the tape winding section 4. By doing so, the punched tape 1 is free from foreign matter such as dust, thereby reducing the number of defects and greatly improving the yield.

In this way, according to this embodiment, it is possible to completely prevent the adhesion of foreign matter such as dust on the tape and dust from the surrounding area, which greatly increases reliability by reducing the defective rate and greatly improving the yield. Not only can this be achieved, but it can also appropriately accommodate high-density packaging of tapes.

Therefore, this embodiment has great industrial significance.

Another embodiment of the invention is shown in FIG.

In this embodiment, the entire equipment is covered with an antistatic cover 6 having a high performance filter 7 attached to the center of the antistatic cover 6. By doing so, the effect of clearing can be improved more than in the case described above.

That is, the front and rear configurations of the die for punching out the tape 1 are the same as in the previous case, but the entire equipment is covered with a cover 6 having a high performance filter 7 attached to the center of the antistatic cover 6.

In this way, by blowing clean air into the tape transport section and preventing the adhesion of surrounding dust, the equipment of this example can be used in a general room, and the yield is higher than in the case described above. do.

[Effects of the Invention] As described above, the present invention provides static electricity removal sections between the tape feeding section and the punching section and between the punching section and the tape winding section, so that foreign substances such as dust are removed. As a result, the number of defects is reduced, and prepress equipment for TAB tapes can be created that enables a significant improvement in yield.
