[Object of the Invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film carrier tape having a tape body provided with a large number of film carrier parts.

[0003]

2. Description of the Related Art In recent years, a film carrier component (generally called TAB) in which a semiconductor chip such as an IC or an LSI is incorporated in a film has been put into practical use. This film carrier component is manufactured by punching one by one from a film carrier tape provided in a large number in series by a punching device. The film carrier component manufactured in this way is mounted on a printed circuit board or a liquid crystal board.

[0004]

By the way, in the case where the film carrier component is punched from the film carrier tape as described above, the structure of the device for punching the film carrier component is complicated, and It was necessary to manufacture a dedicated mold according to the type of film carrier parts.

Therefore, an object of the present invention is to provide a film carrier tape which allows the film carrier parts to be separated by a simple device and which does not necessarily require a dedicated mold according to the type of the film carrier parts. It is in.

[Constitution of Invention]

[0007]

A film carrier tape of the present invention is characterized in that a film carrier component is provided on a tape body so as to be separable by suction.

[0008]

According to the above means, the film carrier component can be separated from the tape body by suction, so that the device for separating the film carrier component is simpler than the case where the film carrier component is punched and separated. You can Further, since the film carrier component is adsorbed and separated, unlike the case of punching, a dedicated mold according to the type of the film carrier component is not necessarily required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. First, the film carrier tape 1 is composed of a tape body 2 and a large number of film carrier parts 3, and is set so as to be fed in the direction of arrow A in FIG. 1 by a feeding device (not shown).

As shown in FIG. 2, the tape body 2 has a two-layer structure including a front sheet 4 and a back sheet 5, both of which are adhered with an adhesive. Then, on the front sheet 4, the film carrier component 3 is attached to the film carrier tape 1.
A large number of the film carrier parts 3 are arranged at a predetermined interval in the extending direction, and each film carrier component 3 is attached to the upper surface of the back sheet 5 with an adhesive. Therefore, each film carrier component 3 is provided so as to be separable from the tape body 2.

The separating device 6 comprises a suction base 7 having a guide groove 7a for guiding the film carrier tape 1 formed on the upper surface thereof, and a suction head 8 provided above the suction base 7 so as to be vertically movable. ing. The suction base 7 and the suction head 8 are connected to a suction device 9, respectively.

In the above structure, when the film carrier component 3 of the film carrier tape 1 is fed to a predetermined position on the suction base 7, the feeding is stopped and the suction head 8 is lowered. Then, the suction base 7 sucks the back sheet 5 of the film carrier tape 1 downward, and the suction head 8 moves upward while sucking the film carrier component 3 portion upward.

Then, the film carrier component 3 adsorbed by the adsorption head 8 is peeled off from the back sheet 5 of the tape body 2, whereby the film carrier component 3 is separated from the tape body 2. In addition, 3a in FIG. 1 has shown the hole after the film carrier component 3 was isolate | separated from the tape main body 2.

The film carrier component 3 thus separated is then transferred to the next step, and finally mounted on a printed circuit board or a liquid crystal substrate (not shown).

According to the above-described embodiment, the film carrier component 3 can be separated from the tape main body 2 by suction by the separating device 6, so that the separating device 6 for separating the film carrier component 3 is a film carrier component. The structure can be simplified as compared with the punching device for punching. Further, since the film carrier component 3 is separated by suction, there is an advantage that the separating device 6 does not necessarily require a dedicated mold corresponding to the type of the film carrier component 3, unlike the case of punching.

Furthermore, when separating the film carrier component 3, vibrations which would occur when punching is not generated,
There is also an advantage that the vibration does not adversely affect others.

3 and 4 show a second embodiment of the present invention. In the second embodiment, the film carrier tape 10 has a structure in which each film carrier component 12 is connected to a single tape body 11 via a plurality of small connecting portions 13 by so-called micro joints.

In this case, therefore, in the separating device 6, the tape base 11 excluding the film carrier component 12 is adsorbed from below by the adsorption base 7, and only the film carrier component 12 is adsorbed from above by the adsorption head 8. The film carrier component 12 is separated from the tape main body 11 by sucking and thereby breaking each connecting portion 13. Even in such a second embodiment, it is possible to obtain the same effects as those of the first embodiment.

[0019]

As is apparent from the above description, according to the present invention, since the film carrier component can be separated from the tape body by suction, unlike the case where the film carrier component is separated by punching, It has an excellent effect that it can be separated by a simple device, and that a dedicated mold corresponding to the type of the film carrier component is not necessarily required.
