Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a series of electronic components for transporting electronic components using a carrier tape having a plurality of concave pockets at predetermined intervals in a longitudinal direction.

[0002]

2. Description of the Related Art Conventionally, the structure of such a series of electronic parts is as follows. That is, a carrier tape having concave pockets at predetermined intervals in the longitudinal direction, an electronic component housed in each concave pocket of the carrier tape, and a top tape that continuously covers the concave pockets of the carrier tape. It had a configuration provided.

[0003]

In recent years, in the above-mentioned conventional example, the number of electronic parts which are conveyed by this series of electronic parts is extremely disliked by moisture. In other words, this electronic component is deteriorated by absorbing moisture,
It will be damaged.

In order to prevent this, it is conceivable to improve the airtightness of the concave pocket by firmly adhering the top tape to the outer periphery of the concave pocket.

[0005] However, when the top tape is firmly adhered to the outer peripheral portion of the concave pocket as described above, there is a problem that when the top tape is peeled to take out electronic components, the top tape cannot be peeled off smoothly from the carrier tape. there were.

Accordingly, an object of the present invention is to smoothly peel off a top tape from a carrier tape.

[0007]

According to the present invention, to achieve this object, the top tape is bonded to the lower carrier tape in a band-like manner on both sides in the longitudinal direction and between the concave pockets. The width of the adhesive band between the pockets is smaller than the width of the adhesive band on both sides.
That is, in the case of the above configuration, the width of the adhesive band on both sides in the longitudinal direction of the top tape is to maintain the airtightness of each concave pocket, and the width of the adhesive band bonding between the concave pockets is Since the width of the adhesive tape is smaller than the width of the adhesive tape, the top tape can be smoothly peeled off when the top tape is peeled off.

Even if the width of the adhesive band between the concave pockets is reduced in this manner, since the adhesive band exists between the concave pockets, the airtightness of each concave pocket can be maintained sufficiently. In addition, the airtightness of the plurality of concave pockets is not impaired at a time, and the electronic components housed therein can be prevented from being deteriorated or damaged due to moisture absorption.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is directed to a carrier tape having a plurality of concave pockets at predetermined intervals in a longitudinal direction, and an electronic device housed in each concave pocket of the carrier tape. A component, and a top tape which continuously covers the plurality of concave pockets of the carrier tape, wherein the top tape is formed in a band shape with the lower carrier tape between both sides in the longitudinal direction and between the concave pockets. The width of the adhesive band between the concave pockets is smaller than the width of the adhesive band on both sides, and the width of the adhesive band between the pockets is set to the width of the adhesive band on both sides in the longitudinal direction of the top tape. By making it narrower than the width of the band, the top tape can be peeled off smoothly when peeling off the top tape, and the airtightness of each concave pocket can be maintained. Since, housed electronic components is deteriorated by moisture absorption, in which it is possible to prevent the damage.

According to a second aspect of the present invention, there is provided the electronic component link according to the first aspect, wherein the adhesive band bonded between the concave pockets has a central portion protruding in a carrier tape conveying direction. In this case, when the adhesive tape that bonds the pockets is made to protrude in the transport direction, the top tape can be more smoothly peeled when the top tape is peeled off.

According to a third aspect of the present invention, there is provided a series of electronic components according to the first or second aspect, wherein an inert gas is sealed in the concave pocket, wherein the inert gas is sealed in the concave pocket. For example, it is possible to more effectively prevent the electronic components housed in the concave pockets from absorbing moisture.

An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 and 2, reference numeral 1 denotes a carrier tape, and the carrier tape 1 is provided with a plurality of concave pockets 2 at predetermined intervals in a longitudinal direction thereof.
The electronic components 3 are housed in these concave pockets 2, and the upper part of the concave pockets 2 is covered with a top tape 4 in this state. This top tape 4 is adhered to the carrier tape 1 as shown in FIG. That is, both sides in the longitudinal direction of the top tape 4 are adhered to the lower carrier tape 1 by the wide adhesive band 5 and between the concave pockets 2 by the narrow adhesive band 6.

As described above, each of the concave pockets 2 is formed by the adhesive bands 6 on both sides and the adhesive bands 6 between the concave pockets 2.
Is adhered to the top tape 4 over the entire circumference thereof, and has an independent sealing configuration for each concave pocket 2. In this case, an inert gas such as a nitrogen gas is sealed in each concave pocket 2 before the top tape 4 is bonded.

That is, the electronic component 3 is accommodated in the concave pocket 2, the upper part is covered with the top tape 4 in an atmosphere of an inert gas such as nitrogen gas, and the adhesive pocket 5 and the adhesive band 6 are used to bond the electronic component 3. The interior of 2 is sealed with an inert gas. Therefore, even if the electronic component 3 housed in the concave pocket 2 is very disagreeable for absorbing moisture, such as a semiconductor package, the inert gas around the electronic component 3 prevents moisture from entering the electronic component 3. It is to prevent.

Now, when mounting the electronic component 3 sealed together with the inert gas in the concave pocket 2 as described above, the top tape 4 is sequentially peeled off from the carrier tape 1 in order to take out the electronic component 3. Will go on.
In this case, the adhesive bands 5 on both sides in the longitudinal direction of the top tape 4
Has a wide width, but since it is linear with the direction in which the top tape 4 is peeled off, the top tape 4 can be easily peeled off.

Further, since the width of the adhesive band 6 between the concave pockets 2 which is perpendicular to the direction in which the top tape 4 is peeled off is reduced, when the top tape 4 is peeled off, this is also required. The adhesive can be easily peeled off.

Attention is paid to each of the concave pockets 2. Since the width of the adhesive band 5 at the outer periphery of the concave pocket 2 is wide, the infiltration of moisture from the sides and the infiltration of The outflow of the active gas is less likely to occur. In addition, the width of the adhesive band 6 is small in the area of the adhesive band 6, and from this point, infiltration of moisture and outflow of inert gas are likely to occur. However, this is true for one concave pocket 2 provided in the carrier tape 1. Even if moisture infiltration or inactive gas outflow occurs in one concave pocket 2, the adjacent concave pocket 2 does not. , It has no effect.

FIG. 3 shows another embodiment of the present invention. In this embodiment, a narrow adhesive band 6 provided between the concave pockets 2 is opposed to an arrow A in a peeling direction A of the top tape 4. (The transport direction of the carrier tape 1 is the direction opposite to the arrow A).

By protruding the adhesive band 6 in the direction in which the top tape 4 is peeled off, the top tape 4 can be more smoothly peeled off from the carrier tape 1.

As described above, the present invention provides a carrier tape having a plurality of concave pockets at predetermined intervals in the longitudinal direction, an electronic component housed in each concave pocket of the carrier tape, and the carrier tape. A top tape that continuously covers the plurality of concave pockets, the top tape is bonded to the lower carrier tape in a band shape between both longitudinal pockets and between the concave pockets, and between the concave pockets. The width of the adhesive band between the pockets is smaller than the width of the adhesive band on each side in the longitudinal direction of the top tape. As a result, the top tape can be smoothly peeled off when the top tape is peeled off, and the airtightness of each concave pocket can be maintained. Or degraded by the electronic components moisture absorption,
It can prevent damage.
