Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, specifically to a chip testing tray and a tray fixing fixture. Background Technology

[0002] With the development of electronic technology, chips are becoming increasingly integrated, with increasingly finer structures, more and more processes, and increasingly complex manufacturing processes. Inevitably, some latent defects will be generated in the chips during the manufacturing process, and these defects usually need to be operated for about a thousand hours before they are fully exposed.

[0003] Therefore, the current main method to accelerate defect exposure is to conduct chip environmental adaptability testing. Environmental adaptability testing usually adopts three-temperature testing, which involves testing at three temperatures: low temperature, room temperature, and high temperature. These are generally defined as low temperature -55°C, room temperature 25°C, and high temperature 125°C.

[0004] When testing chips with a three-temperature testing equipment, the material tray needs to be rotated. In the existing technology, the material tray is an integral structure. Therefore, in order to facilitate positioning, a positioning structure needs to be set on each material tray, which not only increases the volume of the material tray, but also increases the production cost of a single material tray. In addition, the existing positioning structure has a fixed position and poor adaptability.

[0005] In view of this, there is an urgent need for a chip testing tray and a tray fixing fixture to solve the above problems. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A chip testing tray includes: a positioning plate and a tray, wherein the positioning plate is provided with a tray groove, the tray groove is adapted to the tray, and the tray is provided with a plurality of chip placement slots; Several positioning structures are provided on both sides of the positioning disk. Each positioning structure includes a positioning roller and an elastic element. The positioning roller is disposed on the positioning disk, and the elastic element is used to apply a spring force to the positioning roller toward the side away from the positioning disk.

[0008] Two positioning structures are respectively provided on both sides of the positioning disk.

[0009] The positioning structure also includes a mounting base, which is fixed to the positioning plate by bolts, and the positioning roller and the elastic element are disposed on the mounting base.

[0010] The elastic element is a spring or a sheet, and the positioning roller is disposed at the suspended end of the elastic element.

[0011] A tray fixing fixture, based on the chip test tray, includes a carrier board, and two parallel limiting plates are provided on the upper part of the carrier board. The space between the two limiting plates is a tray placement space, which is adapted to the positioning plate.

[0012] Both limiting plates are provided with baffles at the same end, and the two baffles extend toward each other.

[0013] The limiting plate has a guide surface at one end away from the baffle. The guide surface is a plane and is perpendicular to the carrier plate. The guide surface extends obliquely from the side near the baffle to the side away from the baffle, and the oblique direction is the side away from the material tray placement space.

[0014] The carrier plate is provided with a number of rolling balls within the material tray placement space.

[0015] The balls are arranged in two rows, and the extension direction of each row of balls is consistent with the extension direction of the limiting plate.

[0016] Each of the two limiting plates has a plurality of positioning grooves on one side that is close to each other, and the plurality of positioning grooves correspond one-to-one with the plurality of positioning rollers.

[0017] The above-described structure of this utility model can achieve the following beneficial effects: In use, the material tray is placed in the tray slot of the positioning plate to limit its movement. The positioning plate's function is to limit and support the material tray, and it is positioned by several positioning rollers on both sides. That is, when the positioning plate slides into the tooling, the positioning rollers roll in contact with the sides of the tooling, and the elastic element allows the positioning rollers to move closer to or further away from the positioning plate, giving the positioning structure a certain range of self-adaptive capability. In this way, it is not necessary to set a positioning structure on each material tray. During testing and processing, the material tray is simply moved into the tray slot on the positioning plate, and then the positioning plate is slid into the tooling from one side. This eliminates the need for a positioning structure on each material tray, making the material tray structure simpler and reducing the production cost of the material trays.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0022] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0023] Example 1: As Figures 1-2 As shown, a chip testing tray includes: a positioning tray 1 and a tray 2. The positioning tray 1 is provided with a tray groove 11, which is adapted to the tray 2. The tray 2 is provided with a plurality of chip placement slots 21. Since the tray 2 is generally rectangular, the tray groove 11 is rectangular, so as to fix and limit the tray 2. Several positioning structures are provided on both sides of the positioning disk 1. The positioning structure includes a positioning roller 3 and an elastic element 4. The positioning roller 3 is disposed on the positioning disk 1, and the elastic element 4 is used to apply a spring force to the positioning roller 3 toward the side away from the positioning disk 1.

[0024] Based on the above mechanism, during use, the material tray 2 is placed in the material tray groove 11 of the positioning plate 1 to limit the material tray 2. The function of the positioning plate 1 is to limit and support the material tray 2, and the positioning plate 1 is positioned by several positioning rollers 3 on both sides. That is to say, when the positioning plate 1 slides into the tooling, the positioning rollers 3 roll in contact with the two sides of the tooling, and the elastic element 4 allows the positioning rollers 3 to have space to move closer to or away from the positioning plate 1, so that the positioning structure has a certain range of self-adaptive ability. In this way, it is not necessary to set a positioning structure on each material tray 2. During the test processing, the material tray 2 is simply rotated (which can be easily achieved by a robotic arm) into the material tray groove 11 on the positioning plate 1, and then the positioning plate 1 is slid into the tooling from one side. It is not necessary to set a positioning structure on each material tray 2, making the structure of the material tray 2 simpler and reducing the production cost of the material tray 2.

[0025] In a further optimization, two positioning structures are provided on each side of the positioning disk 1 in this embodiment, so as to keep the positioning disk 1 in a centered position after it slides into the tooling 1 and will not deviate.

[0026] like Figure 1 and Figure 2 As shown, the positioning structure also includes a mounting base 5, which is fixed to the positioning plate 1 by bolts. The positioning roller 3 and the elastic element 4 are set on the mounting base 5. This makes it easy to disassemble and assemble the entire positioning structure, and facilitates later maintenance.

[0027] A further optimization is that the elastic element 4 can be a spring or a sheet, and the positioning roller 3 is set at the suspended end of the elastic element 4. After the positioning roller 3 slides into the tooling, it compresses the elastic element 4, thereby restricting the position of the positioning disk 1.

[0028] Example 2: A tray fixing fixture for implementing a chip test tray as described in the example. Figure 3 and Figure 4 As shown, the device includes a carrier plate 6, and two parallel limiting plates 7 are provided on the top of the carrier plate 6. The space between the two limiting plates 7 is a material tray placement space, which is adapted to the positioning plate 1. Thus, the two limiting plates 7 limit the two sides of the positioning plate 1. Furthermore, a baffle 71 is provided at the same end of the two limiting plates 7, and the two baffles 71 extend toward the side that is closer to each other.

[0029] like Figure 3 and Figure 4As shown, the end of the limiting plate 7 away from the baffle 71 is provided with a guide surface 72. The guide surface 72 is flat and perpendicular to the carrier plate 6. The guide surface 72 extends obliquely from the side near the baffle 71 to the side away from the baffle 71, with the oblique direction being the side away from the material tray placement space. The baffle 71 cooperates with the two limiting plates 7 to limit the three sides of the material tray 2 to achieve the purpose of positioning the material tray 2. In order to facilitate pushing the material tray 2 into the material tray placement space, the end of the limiting plate 7 away from the baffle 71 is provided with a guide surface 72. The guide surface 72 is flat and perpendicular to the carrier plate 6. The guide surface 72 extends obliquely from the side near the baffle 71 to the side away from the baffle 71, with the oblique direction being the side away from the material tray placement space. In this way, the opening of the material tray placement space on the side away from the baffle 71 is funnel-shaped, making it easy to insert the material tray 2 between the two limiting plates 7.

[0030] like Figure 4 As shown, in order to reduce the friction between the material tray 2 and the carrier plate 6, the carrier plate 6 is provided with a number of rolling balls 9 in the material tray placement space, and the rolling balls 9 are divided into two rows. The extension direction of each row of rolling balls 9 is consistent with the extension direction of the limiting plate 7, so that the material tray 2 and the carrier plate 6 are in rolling contact, thereby reducing the friction.

[0031] like Figure 3 and Figure 4 As shown, each of the two limiting plates 7 has a number of positioning grooves 73 on one side that is close to each other. The number of positioning grooves 73 corresponds one-to-one with the number of positioning rollers 3. When one side of the material tray 2 abuts against the baffle 71, the number of rollers 3 are respectively engaged in the number of positioning grooves 73 to achieve positioning of the rollers 3, thereby achieving positioning of the material tray 2. The positioning grooves 73 are preferably V-shaped or arc-shaped so that after a certain pushing force is applied to the material tray 2, the rollers 3 can leave the positioning grooves 73, so that the material tray 2 can smoothly leave between the two limiting plates 7.

[0032] In summary, during use, the material tray 2 is placed in the tray groove 11 of the positioning plate 1 to limit the movement of the material tray 2. The positioning plate 1 is used to limit and support the material tray 2, and is positioned by several positioning rollers 3 on both sides of the positioning plate 1. That is, when the positioning plate 1 slides into the tooling, the positioning rollers 3 roll in contact with the sides of the tooling, and the elastic element 4 allows the positioning rollers 3 to move closer to or further away from the positioning plate 1, giving the positioning structure a certain range of self-adaptive capability. In this way, it is not necessary to set a positioning structure on each material tray 2. During test processing, the material tray 2 is simply moved into the tray groove 11 on the positioning plate 1, and then the positioning plate 1 is slid into the tooling from one side. The absence of a positioning structure on each material tray 2 makes the structure of the material tray 2 simpler and reduces the production cost of the material tray 2.

[0033] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
