Description

Semiconductor memory body PCB tray {PCB tray for a semiconductor memory body}

The present invention relates to a semiconductor memory PCB PCB tray, and more particularly, having a plurality of receiving portions having a plurality of insertion grooves integrally formed with support protrusions on both sides of the bottom surface and a body portion having a locking groove formed at each corner thereof, By providing a cover portion with a locking protrusion corresponding to the groove, the semiconductor memory not only prevents damage to the PCB contact terminal received by the support protrusion, but also prevents the cover portion from being detached from the body by the locking protrusion fitted into the locking groove. It relates to a body PCB tray.

In general, semiconductor devices fabricated through various work processes are mounted on a PCB as a final step. The PCB on which the semiconductor device is mounted is stored in a predetermined tray and transferred to the next step. Such a tray has an accommodating portion divided by a plurality of partition walls inside a square body having an open top. PCBs in which semiconductor elements are mounted are fitted in the accommodating parts. In this way, when the PCB is accommodated, the plurality of trays are transferred to the next step in a state where a predetermined cover is covered in order to prevent foreign matter from entering the receiving unit.

However, there is a problem in that the contact terminals are damaged because the contact terminals of the PCB are directly contacted on the bottom surface of the tray accommodating unit. In addition, there is a problem that the foreign material is introduced into the receiving unit by the cover is separated from the body during the transfer.

The present invention is devised to solve the conventional problems as described above, the object of the present invention is a plurality of receiving portions having a plurality of insertion grooves are formed integrally with the supporting protrusions on both sides of the bottom surface and the locking groove is formed in each corner By having a body portion and having a cover portion with a locking protrusion corresponding to the locking groove, not only does it prevent the PCB contact terminal received by the support protrusion from being damaged, but also that the cover portion is separated from the body by the locking protrusion fitted into the locking groove. It is to provide a semiconductor memory body PCB tray that can be prevented.

In order to achieve the object of the present invention as described above, the present invention,

A plurality of housing portions divided by a divider that traverses the inside, and a plurality of barrier ribs are disposed on the bottom surface of the housing to be spaced at predetermined intervals, and a PCB in which semiconductor elements are mounted is inserted between the barrier ribs. A semiconductor memory body PCB tray having a body portion having grooves formed therein and a cover portion covering an upper portion of the body portion,

Each of the first side walls of the body portion extends from the bottom to the top at a predetermined inclination angle and narrows. The first side wall of the body portion is formed by concavely shearing the recess at the center edge of the first side wall. The support protrusion is formed to protrude, and each second side wall of the cover portion is inclined at a predetermined inclination angle from the bottom to the upper side like the first side wall, and is narrowed. Provided is a semiconductor memory body PCB tray formed by convexly shearing inward.

As described above, according to the present invention, there is provided a plurality of receiving portions having a plurality of insertion grooves integrally formed on both sides of the bottom surface and a body portion having a locking groove formed at each corner, and corresponding to the locking groove By providing the cover portion formed with a group, it is possible to prevent the PCB contact terminal received by the support protrusion from being damaged, as well as to prevent the cover portion from being separated from the body portion by the locking projection fitted into the locking groove.

Hereinafter, a semiconductor memory body PCB tray according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

1 is an exploded perspective view of a semiconductor memory body PCB tray according to the present invention, Figure 2 is a perspective view of the bonded state of the semiconductor memory body PCB tray shown in Figure 1, and Figure 3 is a cross-sectional view taken along the line AA of FIG. to be.

1 and 2, the semiconductor memory body PCB tray 100 according to the present invention has a rectangular parallelepiped shape, and has a body portion having a plurality of storage portions 120 divided by a partition plate 112 that traverses the inside. 110 and a cover portion 130 that can cover the body portion 110.

A plurality of partitions 122 are vertically formed on the bottom surface of the accommodating part 120. These partitions 122 are spaced apart at predetermined intervals. In this case, insertion grooves 124 into which PCBs (not shown) on which semiconductor elements are mounted are inserted are formed between the partition walls 122, and the supporting protrusions 126 are formed on the bottom surfaces of the insertion grooves 124. 3) is formed. The support protrusion 126 is formed to protrude upward from both end portions of the bottom surface of the insertion groove 124. Preferably, the support protrusion 126 is mounted on the outer side where the contact terminal of the PCB is not formed.
