However, since the conventional tray for storing electronic parts is made of a thin plate of a thermoplastic resin having poor mechanical strength, it is easily deformed by an external force or impact. When a shock or a load during stacking is applied, there is a problem that electronic parts housed therein are easily damaged such as cracks or chips, or bent lead pins.

The present invention has been made in view of the above-mentioned conventional problems, and it is an object of the present invention to make it difficult to easily deform by an external force, impact, load, or the like, and to damage electronic components housed therein. An object of the present invention is to provide an electronic component storage tray.

A substantially rectangular resin-made electronic component storage tray, characterized in that the skirt portion is provided with a plurality of concave portions which are depressed inward from the upper end to the middle on each side.

According to the electronic component storage tray of the present invention,
Each side of the outer skirt is provided with a plurality of recesses that are depressed inward from the upper end to the middle, so that the plurality of recesses increases the rigidity of the skirt, and the deformation of the tray due to external force, impact, etc. Can be effectively prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an electronic component storage tray according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a top view showing an example of an embodiment of an electronic component storage tray according to the present invention.
(B) and (C) are cutting lines AAB and B- in FIG.
It is sectional drawing in BC.

As shown in FIGS. 1 and 2 (A), (B) and (C), the electronic component storage tray of the present invention is made of a thermoplastic resin such as polystyrene resin, polyvinyl chloride resin or polyester resin. It is formed by processing irregularities by, for example, a vacuum press molding method on a plate material 1 made of resin and having a thickness of about 0.5 to 2 mm.
It has a substantially rectangular shape of about mm, a width of about 50 to 250 mm, and a height of about 5 to 20 mm. The tray of the present invention is substantially rectangular in this example, but may be substantially square.

On the upper surface of the tray, a plurality of electronic component storage sections 2 for storing electronic components are arranged vertically and horizontally. Each of the electronic component storage sections 2 is, for example, a substantially square recess having a side of about 3 to 100 mm, and each is separated by a raised section 3 having a height of about 5 to 20 mm and a width of about 1 to 20 mm. I have. Then, electronic components 8 such as a package for housing a semiconductor element, for example, are placed on the bottom surface of the electronic component housing 2 respectively. In this example, the electronic component storage section 2 is substantially square, but may have another shape such as a rectangle or a circle according to the shape of the electronic component 8 stored therein. Further, around each side of each electronic component storage unit 2, a holder for holding the electronic component 8 when inserting or removing the electronic component 8 (only one is shown) from the electronic component storage unit 2 is inserted. A concave holder insertion part 4 having a width of 5 to 20 mm, a length of about 1 to 20 mm, and a depth of about 1 to 20 mm is provided in communication with the electronic component storage unit 2, for example, a manipulator-like By inserting and removing the electronic component 8 by inserting the tip of the holder into the holder insertion portion 4, the electronic component 8 is inserted.
It is easy to put in and out.

Further, a frame-like skirt portion 5 surrounding the electronic component storage portion 2 formed on the upper surface is formed on the outer peripheral portion of the tray. The skirt 5 has a width of about 1.5 to 20 mm and a height of about 5 to 20 mm.
0.5 mm above the lower surface of the electronic component housing 2
The tray hangs down to a position lower by about 5 mm at an angle of about 1 to 10 ° with respect to the vertical center axis of the tray. The skirt portion 5 imparts a predetermined strength to the tray, and also functions as a guide when stacking the trays vertically, and is inwardly depressed inward from the upper end to the middle.
A plurality of substantially semicircular concave portions 6 having a height of about 1 to 10 mm and a height of about 1 to 10 mm are formed on each side at intervals of about 10 to 100 mm. As described above, since the skirt portion 5 is provided with the concave portion 6 which is depressed from the upper end to the middle, the rigidity of the skirt portion 5 is increased, and thereby the strength of the entire tray is increased. Therefore, even if an external force, impact, or load is applied to the tray, the tray is not easily deformed, and as a result, damage to the electronic components 8 accommodated in the tray can be effectively prevented. . In this example, the concave portion 6 has a substantially semicircular shape, but may have a substantially triangular or square shape. However, it is preferable that the concave portion 6 has a substantially semicircular shape in order to effectively reduce and disperse an external force and an impact applied to the tray.

Further, in this example, the recess 6 is formed at an asymmetric position with respect to the center of the tray. Since the recess 6 is formed at an asymmetric position with respect to the center of the tray, the top view is shown in FIG. 3, and the cutting line D in FIG.
As shown in the cross-sectional view of FIG.
When the plurality of trays containing the electronic components 8 are rotated horizontally by 180 ° with each other and stacked vertically, the positions of the recesses 6 are shifted between the upper and lower trays, so that the upper end of the skirt portion 5 of the lower tray is The lower tray is in contact with the lower surface of the concave portion 6 of the upper tray, and it is possible to effectively prevent the lower tray from entering the upper tray any more. Thus, an appropriate gap G is provided between the electronic component 8 accommodated in the lower tray and the upper tray to effectively apply a load from the upper tray to the electronic component 8 in the lower tray. , And damage to the electronic component 8 due to the load from the upper tray can be effectively prevented.

Furthermore, in this example, the height of the raised portion 3 at the center of the tray is 1 to 10 mm from the lower surface of the electronic component storage portion 2.
A substantially circular column 7 recessed to the lower side is formed at an asymmetric position with respect to the center of the tray. The support column 7 has a concave portion 6
Similarly, when a plurality of trays in each of which the electronic components 8 are stored in each electronic component storage unit 2 are rotated by 180 ° in the horizontal direction and stacked one above the other, the positions of the columns 7 are shifted between the upper and lower trays. The upper surface of the raised portion 3 of the lower tray abuts on the lower surface of the column 7 of the upper tray, and the lower tray can be effectively prevented from entering the upper tray further, together with the recess 6. Thus, a gap G can be ensured between the electronic component 8 accommodated in the lower tray and the upper tray even in the center of the tray, and the electronic component 8 is loaded by the load from the upper tray. Damage can be more effectively prevented. In this example, the column 7 is substantially circular, but may be square or another shape.

Thus, according to the electronic component storage tray of the present invention, it is possible to effectively prevent the electronic components 8 stored in the electronic component storage section 2 from being damaged by external force, impact or load. A component storage tray can be provided.

[0015]

According to the electronic component storage tray of the present invention, a plurality of concave portions are provided on each side of the skirt portion surrounding the electronic component storage portion so as to be depressed inward from the upper end to the middle. Due to the concave portion, the rigidity of the skirt portion is increased, so that deformation of the tray due to external force, impact, etc. can be effectively prevented, and as a result, damage to the housed electronic components can be effectively prevented. .
