Description

Technical Field

[0001] The utility model relates to the field of storage test equipment, and particularly relates to an electronic tag for test equipment. Background Art

[0002] Intelligent manufacturing is one of the core fields of Industry 4.0. Taking the automatic test and sorting of storage products as an example, automatic test and automatic sorting are two important processes, which can be combined into one or separated. For the automated equipment that combines the two processes, due to the increased process functions, the structure is more complex, and its disadvantages such as volume, line change time, and maintenance cost are obvious; for those divided into two automated equipment, the production capacity matching is more flexible. The automatic test equipment takes 1 hour for one round of testing, while the automatic sorting can complete the operation in 6 minutes. In actual ratio, it is 12:1, that is, 12 automatic test equipment are equipped with 1 automatic sorting equipment. However, for the 12:1 ratio, online information processing is the key. In traditional technology, data is transmitted through networking, but the synchronization and consistency between data and physical objects are prone to problems, such as A data matching B physical objects, resulting in test failures. The conventional solution is to add QR codes or barcodes for identity recognition on the product physical objects or turnover trays. However, some storage products are very small in size and are not suitable for QR codes or barcodes, and the turnover trays are repeatedly used, and wear and aging will cause damage to the QR code or barcode graphics, making it impossible to be normally recognized and read.

[0003] Therefore, there is a need to provide an electronic tag for test equipment to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an electronic tag for test equipment, which adopts a small-size integrated design, can be embedded in the turnover tray for repeated use, and has a large storage capacity.

[0022] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model. In addition, all connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. For example, fixed connection / fixed installation can be selected from screw connection, bolt connection, pin connection, key connection, bonding, tenon-mortise connection, welding, riveting, etc. as needed. For example, detachable connection can be selected from screw connection, bolt connection, threaded connection, snap connection, tenon-mortise connection, magic tape connection, etc. as needed. The various technical features in the creation of the present utility model can be combined with each other without conflicting with each other.

[0023] Referring to Figure 1 , an electronic tag for a test device, which is mainly applied to the turnover tray of the test device to store information of test products and can play the roles of identification, chip tracking and information collection. Among them, the electronic tag includes a carrier board 1 and a chip packaging structure. The chip packaging structure includes a memory chip 2 and a USB controller 3. Since the space at the edge of the traditional turnover tray is only 5-8 mm wide, the width of the electronic tag must be less than 8 mm. Therefore, the memory chip 2 is set as an SD NAND chip with a size of 6*8 mm, which can meet the size requirements. However, the SD NAND chip has 8 pin interfaces, and the pin size is too small, requiring a high precision for contact reading. In addition, its interface is an SD interface, while the conventional devices generally have a USB interface, and the SD NAND chip is not suitable for directly being used in the electronic tag. Therefore, the memory chip 2 and the USB controller 3 are respectively connected to the carrier board 1, so that the memory chip 2 is connected to the USB controller 3, converting the SD interface into a USB interface, expanding the applicable range and making it more convenient to use; and a plurality of pin interfaces are provided on the USB controller 3, which is more conducive to meeting the use requirements; in addition, a plurality of pads 6 are provided at the bottom end of the carrier board 1, and 5P large-size and large-spacing PAD pads are used, which is convenient for the test needles of the test device to read and write the information in the electronic tag, and reduces the precision requirement during reading, improving the stability of data transmission.

[0024] Referring toFigure 1 , Figure 2 , in the embodiment of the present utility model, the chip packaging structure further includes a resistor-capacitor component 4 and bonding wires 5. The resistor-capacitor component 4 adopts a streamlined and miniaturized design. The small-sized storage chip 2 and the resistor-capacitor component 4 are directly soldered on the carrier board 1, realizing the high-density integration of electronic components and having a large storage capacity. It can not only store identity information but also store test results. The USB controller 3 is connected to the carrier board 1 through the bonding wires 5, so that the USB controller 3 is communicated with the storage chip 2. And the chip packaging structure further includes an underfill layer 7. The underfill layer 7 is arranged outside the storage chip 2, the USB controller 3, the capacitor component 4 and the bonding wires 5. The welded carrier board and all the components thereon are encapsulated into a whole by using a molding and encapsulation technology to form an integrated electronic tag, which not only simplifies the manufacturing process of the electronic tag but also improves its anti-external interference and protection performance.

[0025] Referring to Figure 3 , in the embodiment of the present utility model, a plurality of the pads 6 are arranged in a double-row staggered distribution, which helps to further reduce the mutual influence between the pads 6, enhances the signal integrity, improves the stability of data transmission, and at the same time improves the flexibility of the layout. Moreover, the staggered layout can better adapt to different sizes and shapes of electronic tags, enhancing the versatility of the design. A plurality of the pads 6 respectively include 4P test pins and LED indicators. Among them, the 4P test pins are 4 key signal points of VBUS, DP, DM, and GND, so that the electronic tag can be used normally through the test pins. This design simplifies the test process and improves the test efficiency. The LED indicator can be an option to view the read-write working status indication of the electronic tag.

[0026] Referring to Figure 3 , in the embodiment of the present utility model, a direction identification mark 8 is further arranged at a corner of the bottom of the carrier board 1, which can avoid installation errors when installing the electronic tag and ensure the normal use of the electronic tag.

[0027] Referring to Figure 4 , Figure 5 , in the embodiment of the present utility model, a mesh copper cladding or a solid copper cladding is arranged on the surface of the carrier board 1. Among them, the mesh copper cladding design can expand and contract better when heated, so as to reduce bending or unevenness caused by thermal stress. The solid copper cladding design not only provides better heat dissipation performance but also can improve the electrical performance of the circuit, such as reducing resistance and providing better current-carrying capacity.

[0028] In practical applications, the electronic tag is embedded in the side end of the turnover tray, which can realize the rapid replacement of the electronic tag. Moreover, the electronic tag has the characteristic of large capacity. It can be used not only to store identity information but also to store test results. Taking the 8*10UDP test as an example, the test data after automatic testing generates a Logo File and is stored in the electronic tag. The automatic sorting machine can perform sorting by reading the electronic tag and sort those with the same grade onto the same tray.

[0029] The above is a specific description of the preferred embodiment of the present invention. However, the present invention is not limited to the described embodiment.
