Preferably, the groove is of a quadrilateral structure, and the step parts are arranged at four corners of the groove. The quadrangle structure adapts to the shape of the chip, and the step part is arranged on four corners, so that the chip is more stable when placed.

Preferably, the bottom surface of the groove is provided with an octagonal through hole, the groove is of a quadrilateral structure, and the stepped portions are arranged at four corners of the groove and form four sides of the through hole.

Preferably, the groove is of a quadrilateral structure, and a first concave part which is concave inwards is arranged on the side surface of the groove.

Preferably, the groove is of a quadrilateral structure, and four corners of the groove are provided with second concave parts which are concave inwards.

The first concave part and the second concave part are convenient for taking the chip.

A chip testing apparatus, comprising:

the test box is used for testing the chip;

a tray as described above;

a transport mechanism for transporting the tray into the test box; and

the code scanner is arranged in the test box;

the chip is provided with a bar code or a two-dimensional code, and the bar code or the two-dimensional code can be scanned by the bar code scanner.

Preferably, the chip testing apparatus further includes: and the card reader is arranged at the upstream of the conveying mechanism and can identify the model of the chip.

The card reader and the code scanner can accurately identify which chip or which chip is tested, so that the test result can be accurately output.

The positive progress effects of the invention are as follows: the chip can be well held by the plurality of step parts in the tray, so that the chip can be stably placed in the test process. The chip testing apparatus can stably transfer a chip and test the chip.

Detailed Description

The present invention is further illustrated by way of example and not by way of limitation in the scope of the embodiments described below in conjunction with the accompanying drawings.

As shown in fig. 1-2, the tray 10 is used for placing chips, a groove 11 is disposed on a surface of the tray 10, a plurality of steps 12 are disposed on a side surface of the groove 11, and the plurality of steps 12 are located on the same plane. When the chip is loaded, the chip is held by the step portion 12.

The bottom surface of the groove 11 is provided with a through hole 13. If the bottom surface of the recess 11 is a solid result, when the chip is put in, the chip may not be easily put in since the air inside the recess 11 is compressed inside. Therefore, the bottom surface of the groove 11 is hollowed out, so that air resistance is avoided when the chip is placed, and the chip is conveniently placed. At the same time, it is also convenient to test the chip from above and below the chip.

The groove 11 is a quadrilateral structure, and the step parts 12 are arranged at four corners of the groove 11. The quadrangle structure is adapted to the shape of the chip, and the step parts 12 are arranged on the four corners, so that the chip is more stable when placed.

As shown in fig. 1, the bottom surface of the recess 11 is provided with an octagonal through-hole 13, and the stepped portion 12 forms four sides of the through-hole 13. The bottom surface of the groove 11 is hollowed out in a large area, so that the chip can be conveniently tested from the lower part of the chip.

The groove 11 is of a quadrilateral structure, and the side surface of the groove 11 is provided with a first concave part 14 which is concave inwards.

The groove 11 is of a quadrilateral structure, and four corners of the groove 11 are provided with second concave parts 15 which are concave inwards.

The first recess 14 and the second recess 15 facilitate the insertion of fingers and gripping means for removing the chip from the recess 11.

As shown in fig. 3, the chip test apparatus 20 includes: the test box 21, the test box 21 is used for testing the chip; a tray 10; a transfer mechanism 22, the transfer mechanism 22 being for transferring the tray 10 into the test box 21; and a code scanner (not shown) provided in the test box 21; wherein, be equipped with bar code or two-dimensional code on the chip, bar code or two-dimensional code can be scanned to the bar code scanner.

In the embodiment, a conveyor belt is used as the conveying mechanism 22, and those skilled in the art can select other mechanical structures as the conveying mechanism 22 according to the requirement. When a chip placed in the tray 10 is transferred to the front of the test box 21, an extracting mechanism in the test box 21 removes the tray 10 from the conveyor belt, transfers it to the test box 21, and tests the chip.

The chip test apparatus 20 further includes: and a card reader 23, wherein the card reader 23 is arranged at the upstream of the transmission mechanism 22 and can identify the model of the chip.

The card reader 23 and the code scanner are simultaneously arranged to accurately identify which chip or chips are tested, thereby accurately outputting the test result.

The card reader 23 and the code scanner are commercially available and will not be described in detail.
