Detailed Description of the Invention

[0001]

The present invention relates to TCP (Tape Car).
The present invention relates to a carrier tape slide carrier for holding a carrier tape of a tier package) type.

[0002]

2. Description of the Related Art In recent years, with the high density mounting of IC and LSI packages on a substrate, miniaturization of packages, narrowing of pitch, and increase in the number of pins have been rapidly advanced.

For this reason, attention has been paid to the TAB TCP, which can be expected to make the package compact and have a narrow pitch. This general structure is a small and thin IC package in which an IC chip is built in a carrier tape and transfer molded with a resin.

As the pitch becomes narrower and the number of pins increases as described above, it becomes difficult to keep the thin lead terminals with accuracy until just before mounting on the substrate. Therefore, a slide carrier is provided as a guard ring, which is cut and formed immediately before mounting on a substrate.
The structure of this slide carrier for tape carrier is generally such that a square hole for bonding an IC chip is provided in the center and a bottom is surrounded to protect the carrier tape. It has a formed frame and a tape holding member for holding a carrier tape on the bottom of the frame, and a conventional slide carrier will be described below.

FIG. 5 is a schematic plan view of an example of a conventional slide carrier as described in US Pat. No. 4,069,496 showing a state in which a carrier tape is fitted. FIG. 6 is a cross-sectional view of the slide carrier shown in FIG. 5, taken along the line AA.

As shown in FIGS. 5 and 6, this slide carrier has a plurality of hook-shaped tape holding members 5 corresponding to the sprocket holes 53 of the carrier tape 52.
5 is integrally provided on the slide carrier main body 54, and a carrier tape 52 connected to the IC chip 51.
Is held by the slide carrier body 54 by engaging the sprocket hole 53 with the tape holding member 55.

Further, as shown in FIGS. 7 and 8, different structures for holding the carrier tape 52 are also known.

FIG. 7 is a schematic plan view of another example of a conventional slide carrier as described in US Pat. No. 4,937,655 showing a state in which a carrier tape is fitted.
FIG. 8 shows the relationship between the tape holding member and the jig.
FIG. 8 is a schematic enlarged view of the vicinity of a tape holding member of the slide carrier shown in FIG. 7. As shown in FIGS. 7 and 8, elastic tape holding members 66 provided at the four corners of the slide carrier body 63 are integrally provided. On the other hand, in the automatic machine that mounts the carrier tape 62 on the slide carrier body 63, each tape holding member 66 has a pin-like shape as an engaging member that can move linearly toward the outside of the slide carrier body 63. A jig 68 is provided. In this slide carrier, first, jigs 68 are engaged with the tape holding members 66, and the tape holding members 66 are simultaneously pulled outward by the jigs 68 (in the horizontal direction in the drawing) to slide the slide carrier body 6
The tape alignment pin 64 of No. 3 is inserted into the sprocket hole 6 of the carrier tape 62. As a result, the carrier tape 62 is arranged at a predetermined position. Then, when the jigs 68 are returned to their original positions, the tape holding member 66 is restored to its original state due to its elasticity, and the tape holding members 66 are engaged with the four corners of the carrier tape 62. Held at 63.

[0009]

However, among the slide carriers according to the prior art described above, FIGS.
In the case shown in FIG. 3, when the sprocket hole 53 of the carrier tape 52 is passed through the head of the tape holding member 55, the sprocket hole 53 is forcibly pushed and expanded, and the periphery of the sprocket hole 53 may be deformed so as to turn up. is there. Also, in some cases, the carrier tape 52 may be cracked. When such a situation occurs, the slide carrier main body 54 with the carrier tape 52 mounted thereon.
During transport, carrier tape 52 sprocket hole 5
3 may come off the tape holding member 55, and the carrier tape 52 may fall off the slide carrier body 54. Therefore, there is a problem that the holding of the carrier tape 52 on the slide carrier body 54 becomes unstable.

On the other hand, in the slide carrier shown in FIGS. 7 and 8, when the tape holding members 66 are simultaneously pushed outward at four positions (horizontal direction in the drawing) by the jigs 68 which can move oppositely on a straight line, Since the tape holding member 66 has a cantilever structure with respect to the slide carrier main body 63, the tape holding member 66 is deformed around the joint 67 with the slide carrier main body 63 as a fulcrum. Moves in an arc.

As shown in FIG. 8, the jig 68 is pressure-contacted from the first contact point 69 that contacts before the tape holding member 66a deforms to the second contact point 70 that contacts when the tape holding member 66a deforms. It moves on a straight line in the moving direction 71. With the movement of the jig, the tape holding member 66 and the jig 68 slide, and sliding powder is generated. If the sliding powder adheres between the electrode terminals having a narrow pitch or on the bonding surface, the mounted IC chip may be short-circuited.
Therefore, there is a problem that the carrier tape becomes a defective product.

The present invention has been made in view of the above problems of the prior art. A carrier tape can be mounted by a device having a simple structure, and when the carrier tape is mounted, sliding powder is not generated, Moreover, it is an object of the present invention to provide a slide carrier that can reliably hold a carrier tape.

[0013]

The carrier tape is mounted by pushing and spreading the holding member, and the tape holding member is configured to cover at least a pair of inner side surfaces of the inner surface of the frame so as to relate to the upper surface of the carrier tape mounted to the bottom portion. It is characterized in that both ends are fixed to each of the side surfaces.

The tape holding member may have a recess formed therein, or the recess may be formed in the central portion of the tape holding portion.

[0015]

In the slide carrier for carrier tape according to the present invention constructed as described above, the tape holding members fixed to at least a pair of inner side surfaces facing each other of the inner side surfaces of the frame of the slide carrier are pushed outward. By being expanded, a space into which the carrier tape can be inserted is opened. The carrier tape is inserted into this space, and then the tape holding member is returned again to hold the carrier tape by the tape holding member.

Further, when the carrier tape is inserted into the slide carrier in the automatic machine, the concave portion of the tape holding member formed so as to hang on the engaging member provided in the automatic machine is pushed outward by the engaging member. By being expanded,
A convex portion formed continuously across the concave portion is expanded along the concave portion. Due to this deformation of the tape holding member, the convex portion formed at the position related to the upper surface of the carrier tape shifts to the outside, and the space into which the carrier tape can be inserted is opened. Then, as described above, the carrier tape is inserted into this space, and then the jig is separated from the concave portion of the tape holding member, whereby the tape holding member is returned again. Therefore, the carrier tape is held by the tape holding member.
