DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer lead bonding apparatus and, more particularly, to an apparatus for neutralizing static electricity generated when an interlayer paper is separated from a film carrier, thereby preventing breakage of a chip due to the static electricity. It is.

[0002]

2. Description of the Related Art An electronic component manufacturing process known as a TAB method includes a process of forming a bump on an inner lead of a chip or a film carrier, an inner lead bonding process of bonding the chip and the inner lead, and a process of bonding the film carrier. After punching, an outer lead bonding step of bonding the outer leads of the film carrier to the substrate.

[0003] The inner lead bonding and the outer lead bonding are performed by separate devices.
Therefore, the film carrier for which the inner lead bonding has been completed is once wound around a supply reel together with the interlayer paper, and the supply reel is set in the outer lead bonding apparatus.

[0004] This outer lead bonding apparatus
While taking out the film carrier from the supply reel, the interlayer paper is separated from the film carrier, and the interlayer paper is taken up by the take-up reel, and at the same time, the taken-out film carrier is sent to the punching device by the pitch feeder. The pitch is sequentially fed.

[0005]

However, in the conventional apparatus, when separating the interlayer paper from the film carrier, there is a problem that static electricity is generated and the chip is easily broken.

Accordingly, an object of the present invention is to provide an outer lead bonding apparatus which solves the problems of the conventional means.

[0007]

For this purpose, the present invention provides a supply reel on which a film carrier to which a chip is bonded is wound together with an interlayer paper, a take-up reel for winding the interlayer paper, and a film carrier. Pitch feeding means for feeding pitches toward a punching device, an ion generator for generating ions, and an ion blower connected to the ion generator, wherein the film carrier supplies
Derivation start point to derivation end point to start derivation from reel
From the film carrier in the range of up to locations the interlayer sheet is separated, it is obtained by the blown out ions from the ion outlet portion.

[0008]

According to the above construction, the ions generated by the ion generator are blown out from the ion blower to the portion where the interlayer paper is separated from the film carrier, so that the static electricity generated when the interlayer paper is separated from the film carrier. To prevent chip destruction due to static electricity.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an overall front view of the outer lead bonding apparatus. Reference numeral 1 denotes a supply reel on which a film carrier 2 to which a chip P is adhered by inner lead bonding is wound together with an interlayer paper 3.

Reference numeral 4 denotes a take-up reel, which is rotatably disposed below the supply reel 1 and takes up the interlayer paper 3 wound between the film carriers 2.

Reference numeral 5 denotes a punching device for punching the film carrier 2 to obtain a device D. This punching device 5 is composed of an upper die 5a and a lower die 5b, and moves the upper die 5a up and down with respect to the lower die 5b while the chip P is stopped between the upper die 5a and the lower die 5b. The device D is obtained by punching out the film carrier 2.

Reference numeral 6 denotes a sprocket for feeding the film carrier 2 at a pitch from the supply reel 1 to the punching device 5, and a plurality of sprockets are provided on the transport path of the film carrier 2. 7 is a guide roller.
M is a motor. By driving the motor M, the sprocket 6 rotates at a pitch and the film carrier 2 is pitch-fed. The sprocket 6, the guide roller 7, and the motor M constitute a pitch feed unit for the film carrier 2.

Reference numeral 9 denotes an XY table. The XY table 9 is provided with a nozzle 10 for sucking and picking up the device D punched by the punching device 5.

Reference numeral 11 denotes a cutter for cutting the remaining film carrier 2 from which the device D has been punched into strips.

Reference numeral 12 denotes an ion generator for generating ions, and reference numeral 13 denotes an ion blower connected to the ion generator 12 via a flexible connecting pipe 14. The blowout section 13 is disposed between the supply reel 1 and the take-up reel 4, and the ion blowout section 13 has a portion E (E1, E1) where the interlayer paper 3 is separated from the film carrier 2.
Towards E2) has a trumpet-shaped air outlet 16 which opens is mounted, in a range from the derived start point E1 of the film carrier 2 starts to derive from the supply reel 1 derived to the end point E2 that always blows ions You can do it. The ions generated by the ion generator 12 are blown through the connection pipe 14 from the outlet 16 of the ion blower 13 to the location E where the interlayer paper 3 is separated from the film carrier 2.

The apparatus according to the present embodiment has the above-described configuration, and the operation will be described next. The motor M is driven to rotate the sprocket 6, and the film carrier 2 wound around the supply reel 1 is taken out. At the same time, the winding of the interlayer paper 3 by the winding reel 4 is performed. At this time, at the place E where the interlayer paper 3 is separated from the film carrier 2, static electricity is generated due to the separation of the interlayer paper 3.
By discharging ions from the ion blowing section 13 through the air outlet 16, static electricity generated when the interlayer paper 3 is separated from the film carrier 2 is neutralized, which is likely to occur when the interlayer paper 3 is separated. The chip P can be prevented from being damaged by static electricity.

The present invention is not limited to the above embodiment. For example, a swinging means such as a motor for swinging the ion blowout section is provided, and the film carrier starts to be drawn out from the supply reel from the lead-out starting point E1. End point E
Up to 2, the ions may be ejected while swinging the ion ejection section.

[0019]

As described above , according to the outer lead bonding apparatus of the present invention , a film carrier is provided.
The static electricity generated when the interlayer paper is separated from the film carrier while being taken out of the supply reel can be neutralized to prevent the chip from being easily broken when the interlayer paper is separated due to the static electricity.
