Abstract

PROBLEM TO BE SOLVED: To make it possible to smoothly house and take electronic components in and out of a recessed case with reliability, and prevent electronic components housed in the case from being brought into contact with the side walls or bottom plate of the case to cause damage to the electronic components or the carrier tape itself due to vibration produced during the winding or transport of the carrier tape. SOLUTION: A long, thermoplastic resin sheet is pressed to form on a carrier tape 1 cases 2 having a pedestal-like portion 4 in the center of its bottom 3. The four corners of the bottom 3 surrounding the pedestal-like portion 4 are slit into an L-shape. The L-shaped bottom in contact with the slits is pushed up from beneath, and is bent outward to form L-shaped projected edges 5.

This carrier tape is formed from a long thermoplastic resin sheet by press molding, vacuum molding,
It is integrally molded by pressure molding, vacuum pressure molding, etc.,
The inclination angle θ of the rib h with respect to the pedestal portion e in relation to the molding die
Cannot be made small, and even if an attempt is made to provide a pedestal part e having a shallow bottom while leaving only the periphery of the pedestal part d, the void below the remaining rib h cannot be excluded due to the design of the mold. , Rib h
The width W of the electronic component becomes thicker and becomes closer to the gap between the main body f of the electronic component and the lead portion g, and the rib h fits into this gap to prevent the electronic component from being taken out from the concave container b, or the lead portion of the electronic component. There is a risk that g may be damaged such as bending. In particular, since the rib h has a large rigidity, this problem is likely to occur, and the lead portion g may interfere with and come into contact with the rib h to be damaged. On the other hand, JP-A-6-2556
No. 73, it is assumed that a trapezoidal portion is provided at the center of the bottom of each concave container of the carrier tape, and L-shaped projecting edges are provided along the peripheral edge at the four corners of the trapezoidal portion. It is disclosed that an attempt is made to position the electronic component body placed on the trapezoidal portion at the edge. Particularly in the case of press molding, this carrier tape is produced by forming a trapezoidal part on each concave container and then providing a protruding edge on this trapezoidal part. There is a risk of damage to the electronic components, and the parallelism of the stored electronic components is not good, which may cause a mistake in taking out the electronic components during mounting.

Further, the applicant first provided a trapezoidal portion at the center of the bottom of each concave container, slitted the inclined portion around the trapezoidal portion, and formed a loose piece fixed on one outer side, and We proposed a method for manufacturing a carrier tape that pushes the loose piece outward from below to form an opening and a protruding edge that circumscribes the opening.However, in this case, the protruding edge is formed by bending one side of the outer side, and therefore the reel winding is performed. It has a drawback that it is likely to fall inward due to the stress due to the bending at the time of picking, and it tends to fall due to a change with time. Therefore, the object of the present invention is to be able to smoothly and reliably store and take out electronic components in the concave container, and to store the electronic components in the concave container due to winding of the carrier tape and vibration during transportation. (EN) Provided is a method for manufacturing a carrier tape, in which a component is not damaged by contact with a side wall or a bottom plate and the carrier tape itself is not damaged.

According to the present invention, the concave container of the carrier tape and the base portion for mounting the electronic component body on the center of the bottom portion are integrally formed, and then the bottom portion around the base portion of the concave container is formed. The four corners are slit into L-shapes, and the L-shaped bottom plate circumscribing the slits is pushed up from below and bent outward to form L-shaped projecting edges. Since the protruding edge is formed on the bottom portion different from the mounting trapezoidal portion, there is no fear of damaging the flat surface of the trapezoidal portion, and each protruding edge is composed of two sides and has a structure to support each other. Therefore, there is no risk of deformation or collapse due to the stress at the time of winding the reel or the restoring force with time. Moreover, since the projecting edge is composed of the bottom plate formed by punching and raising, the rigidity is low, there is no fear of damage such as bending of the lead part even if it comes into contact with electronic parts, and the electronic parts are oversized. Since it is not held by force, the electronic component can be taken out smoothly.

The slit shape of the bottom plate 23a formed by the punching blade 45 is as shown in FIGS. 6 (a) and 6 (b).
The outer surface of the corner is removed or rounded to R, Fig. 6
As shown in (c) and (d), the inside corner portion may be cut into a circle, a rectangle, or the like. In the latter case, the R of the corner portion of the projecting edge can be escaped.
Even if the corner R of the main body of the electronic component to be stored is small, the electronic component is effectively held. Note that FIG.
In, the slit part is shown by a solid line and the bent part is shown by a dotted line. Although not shown, in the resulting carrier tape, in the subsequent third step, a hole for identifying a component is formed in the central portion of the upper surface of the base 24 of the concave container 22, and the series of steps described above are repeated. The desired carrier tape 21 is completed. In the carrier tape 21 manufactured in this manner, since the projecting edge 25 is formed by cutting and raising, it is said that the carrier tape 21 fits between the main body Pa of the electronic component and the lead portion Pb without thickening. Such troubles can be prevented, and the flange 25 is 2
Since the two edge pieces are in a state of supporting each other at a right angle, it is possible to prevent the protruding edge 25 from falling down over time and becoming unable to store electronic components.
