Description

[Detailed description of the invention] This invention accommodates multiple semiconductor integrated circuit dual in-line packages in a row, transports and
Concerning storage tools used for storage, testing, etc.

The following storage tools have been used when transporting semiconductor integrated circuit dual in-line packages (hereinafter referred to as "packages"). To prevent electrostatic damage to the input transistors of integrated circuits, the lead legs protruding from the package were placed on a plate made of conductive material, which was then transported in a paper box or synthetic resin container. .

However, in recent years, improvements in test automation for integrated circuits have progressed, and new transport and storage tools have been developed accordingly. It is a tool that has a cylindrical shape with both ends open and uses a storage container made of conductive material or non-conductive material with conductive paint coated on the inside and outside. After one integrated circuit is sent out and tested by the automatic testing device, the packages are placed one by one in a storage container placed below the automatic testing device and stored therein.

A conventional storage device of this type has a structure as shown in a perspective view in FIG. Reference numeral 1 denotes a storage container having a cylindrical shape with both ends open, and a slit 1a extending longitudinally through the center of the upper side in the width direction, and an inward guiding protrusion 1b extending longitudinally in the middle of the bottom side. It is made of synthetic resin and coated with a conductive material on its inner and outer surfaces, or made of a conductive material such as aluminum. Reference numeral 2 denotes a pair of stoppers made of an elastic material such as rubber, which are packed at both ends of the storage container 1. 3 is a package cage, with lead legs 4 extending downward from both sides.
The slit 1a of the storage container 1 is provided so that the appearance of the package 3 and printed characters can be confirmed, and has a width so that the package 3 does not slip out.

To store the package 3 in the above storage tool,
First, a stopper 2 is packed in one end of the storage container 1. Next, the package cages 3 are sequentially placed into the storage container 1 from the other end in the direction of arrow A. FIG. 1 shows this state. In this way, the package 3 is inserted until it is close to the other end, and the other stopper 2 is packed to prevent the inserted package 3 from coming out and to stop the movement in the longitudinal direction.
The state in which the package cage 3 is housed in the storage container 1 is as follows.
FIG. 2 shows a front sectional view.

In order to transport the storage equipment containing the package cage 3 in this manner, a number of storage equipment are collected, or a rubber ring or the like is placed on top of the storage equipment and the bundled bundles are placed in a cardboard box or the like.

In the above-mentioned conventional package storage tool, each package 3 housed in the storage container 1 is prevented from moving in the longitudinal direction by the locks 2 at both ends, but in the direction of arrows B and C shown in FIG. can be moved because there is a gap. Therefore, when a severe impact is applied during transportation, the package 3 often hits the inner surface of the storage container 1 in the directions of arrows B and C, resulting in damage to the package 3. Furthermore, if the locking screw 2 became loose, collisions between the package cages 3 also occurred.

This invention consists of inserting a protective presser rod-like body with elasticity and constrictions on both ends into a cylindrical storage container through a slit on its upper side, and attaching it to both ends of a guide protrusion from the bottom of the storage container. Insert the above-mentioned constricted part into the cut-out hole for hanging, and use this stretched protective presser bar to press down and fix the package cages housed in a row from above, even if there is an external shock. It is an object of the present invention to provide an integrated circuit package storage tool in which a housed package can be stably held and damage can be prevented.

FIG. 3 is a perspective view of the package storage tool according to one embodiment of the invention, with the protective presser bar removed. In the figure, reference numeral 11 is made of the same material as the conventional storage container 1, and similarly, a slit 11a is passed through the center of the top side in the longitudinal direction, and an inward guide protrusion 11b is provided in the middle of the bottom side in the longitudinal direction. However, the following points are different. That is, hook cut holes 11c are provided at both ends of the guide projection 11b. Reference numeral 12 denotes a protective presser rod-shaped body made of an elastic material such as rubber, which has constrictions 12a at both ends, and has a diameter that allows it to be passed through the slit 11a of the storage container 11 from above. The diameter of the portion 12a is the diameter of the cut hole 11.
c is sized so that it can be fitted in the axial direction from the outside of the end.

In order to store the package 3 in the storage tool of the above-mentioned embodiment, the following steps are taken. First, storage container 11
Insert the package 3 one after another in the direction of arrow A from one end. Predetermined quantity of inserting guide protrusions 11
When the presser rods 12 are arranged on the top b, the presser rod-shaped body 12 is passed through the slit 11a from above in the direction of the arrow D, and the constricted portion 12a of one side is axially fitted into the cut hole 11c of the other side and hooked thereon. Next, pull the other side of the presser rod-shaped body 12 and insert the other constricted portion 12a into the other cut hole 11.
c in the axial direction and hook it to hold it. This state is shown in a perspective view and a front view in FIGS. 4 and 5,
The housed package cage 3 is pressed down from above by a protective presser rod-shaped body 12, and is also axially sandwiched and fixed from both ends.
It is designed not to move even when external shocks are applied to it.

There is a gap between the top surface of the package 3 and the top side of the storage container 11, and the presser rod-shaped body 12 has a slit 11a.
It is made so that it does not protrude upwards.

Typical binding cords for packing are tape-shaped and have a large width, making it troublesome to pass through the slit 11a, but the presser rod-like body 12 is rod-shaped and can be easily passed through the slit 11a, making it extremely easy to attach and detach.

The outer periphery of both ends of the storage container 11 with the presser rod-shaped body 12 hung over the contained package cage 3 may be tied together with the presser rod-shaped body 12 with a rubber band or adhesive tape, so that the package cage 3 is securely fixed. be done.

In addition, although the presser rod-shaped body 12 has a round bar shape in the above embodiment, it may also have a polygonal bar shape.

Further, the surface of the presser rod-shaped body is not limited to being smooth, and may have a surface with small grooves.

Further, in the above embodiment, the conventional stop screw 2 is not used, but if both ends of the storage container 11 are extended and the cut length of the cut hole 11a is made longer, the stop screw 2 can be further used. Good too.

As described above, according to this invention, hooking holes are provided at both ends of the guide protrusion from the bottom of the storage container, so that the package cage inserted in the storage container has elasticity at both ends. Insert a protective presser rod with a constricted part through the slit on the top side of the storage container, hook it into one notch hole with one constricted part, and hook it into the other notched hole with the other constricted part and tension it. In addition to pressing the package cage from above, we also made it possible to press it from both ends.
The package is securely fixed and protected, preventing damage from external impact. Moreover, a conventional storage container can be effectively utilized by simply machining a pair of cut holes for hooking.

Note that the presser rod-shaped body can be easily passed through the slit and can be easily attached and detached, improving work efficiency. Furthermore, the attached presser bar prevents foreign matter from entering through the slit and protects the top surface of the package. Moreover, the presser rod-like body has elasticity and has a larger section modulus than a general tape-like tie string, so that it has a strong pressing force against a large number of arrayed packages. In this way, even if the presser rod-like body is attached, a large number of storage containers can be stacked and stored or transported without protruding upward from the slit.

Furthermore, this invention can be applied even if the material of the sealing body of the integrated circuit dual in-line type package is various, and the above-mentioned effects can be achieved. It is particularly effective in preventing breakage when applied to a glass-sealed ceramic package with a glass window, which has become similar to the above, and is also effective in preventing dust from adhering to the glass window.
