Description

Technical Field

[0001] This invention relates to the field of integrated testing and labeling equipment technology in the semiconductor packaging and testing industry, and is applicable to the installation and fixing of test sockets in integrated testing and labeling sorting machines, ensuring that the test sockets are installed and fixed quickly and effectively. Specifically, it relates to a fixture for installing test sockets in integrated testing and labeling equipment. Background Technology

[0002] Semiconductor sorting machines are indispensable equipment in semiconductor testing, playing a crucial role, especially in chip design verification and final product testing. They are primarily used in integrated circuit design and packaging testing, often in conjunction with testing machines. In the front-end design field, sorting machines inspect packaged chips at the chip level. In the back-end, after chip packaging, the combined use of testing and sorting machines performs functional and stability tests on the finished circuits, selecting qualified products and sorting, recording, and statistically analyzing them based on device performance to ensure that the finished circuits meet design specifications in terms of function and performance.

[0003] In integrated circuit design and packaging testing, sorting machines work in conjunction with testing machines to perform final chip testing, ensuring chip quality through a testing platform. In the front-end design stage, sorting machines primarily handle the fine-tuning of packaged chips. The back-end, after chip packaging, involves the collaborative work of testing machines and sorting machines to perform final chip testing, or Final Test. This stage aims to conduct comprehensive functional and electrical parameter tests on each packaged chip to differentiate between superior and inferior chips or to classify them. Currently, domestic sorting machines mainly undertake final chip testing, involving testing platforms including testing machines, sorting machines, test sockets, and other equipment and materials. Their testing process is quite similar to wafer testing, ensuring strict control over every step of chip quality.

[0004] Gravity-based, translational, turret-based, and integrated test and labeling machines each have their own characteristics and are suitable for different testing scenarios and requirements. Gravity-based machines have a simple structure and low investment; translational machines have significant advantages when testing for long periods or advanced packaging; turret-based machines are suitable for small, lightweight chips requiring short-term testing. Integrated test and labeling machines integrate testing, visual measurement, laser marking, and tape bonding, among other functions, but have a complex structure and high technical requirements. The integrated test and labeling sorting test fixture uses a screw and nut installation method, which is currently inconvenient and carries the risk of damaging the electronic components of the test board. Summary of the Invention

A test fixture is a tool used to test electronic products, typically composed of multiple modules, each with one or more functions, used for testing components such as circuit boards and batteries. Test fixtures typically use components such as sensors, test jigs, and connectors to test the performance of electronic products and record the test results during the testing process.

[0022] In a specific embodiment of this application, specific reference is made. Figure 1 and Figure 2The fixture includes: a fixture body 1, which is an integrated flat plate structure. The flat plate structure reduces production costs. The dimensions of the fixture body 1 match the dimensions of the test socket mounting area, and the fixture body 1 is made of plastic insulating material. The fixture body 1 has a boss 3 and a groove 2, the dimensions of which correspond to the dimensions of the components in the test socket mounting area. The boss 3 and groove 2 adjust the safe distance between the fixture body 1 and the sensitive area of ​​the circuit board. Specifically, a groove 2 is integrally formed on the upper surface of the central area, corresponding to the component area of ​​the circuit board under test mounting part; the boss 1, integrally formed with the fixture body, is located on the upper surface of the edge area of ​​the fixture body, corresponding to the non-component area of ​​the circuit board under test mounting part. The sum of the depth of the groove 2 and the height of the boss 1 is greater than the height of the tallest component protruding from the circuit board under test mounting part. The characteristics of the test fixture in this embodiment are: strong adaptability; the test fixture can adapt to various products, whether hardware, software, or systems, and can meet different customer requirements.

Furthermore, it is easy to operate: the test fixture can significantly reduce manual operation, enabling fast and accurate testing and improving testing efficiency.

[0025] In one specific embodiment of this application, the boss 3 is disposed on the side of the fixture body 1 facing the circuit board, and contacts non-sensitive areas on the circuit board through the boss 3. In some embodiments, the boss 3 can be multiple distributed or arranged in a ring. The boss 3 can maintain a certain safety space between the fixture body 1 and the circuit board, and the fixture body 1 does not need to be in complete contact with the circuit board, reducing the contact of the fixture body 1 with sensitive areas of the circuit board. In this embodiment, the optimized fixture design can not only improve the stability of testing, but also reduce the frequency of fixture replacement, thereby improving production efficiency. The modular design of the fixture can easily be adjusted for compatibility with chips of different specifications.

[0026] In one specific embodiment of this application, the sum of the height of the boss 3 and the depth of the groove 2 is greater than the maximum height of the electronic components on the test board. The boss 3 ensures that the fixture body 1 maintains sufficient safety space with the sensitive areas on the circuit board. The boss 3 can ensure that the fixture body 1 will not cause mechanical interference to the tallest components on the test board. At the same time, it can fully utilize the resources of the testing equipment by combining multiple test samples for testing through batch testing, maximizing test output and equipment utilization.

[0027] In one specific embodiment of this application, the groove 2 is disposed in the area corresponding to the high-protrusion components on the circuit board. The groove 2 allows the fixture body 1 to avoid sensitive areas on the circuit board. The groove 2 can be set according to the height of the components on the circuit board, further preventing mechanical interference between the fixture body 1 and the components. During testing, different types of chips require testing instruments with different precision and capacity; proper selection avoids over-configuration and waste. Simultaneously, the fixture in this embodiment can improve the service life of the testing equipment. Through regular maintenance and calibration, it ensures that the testing equipment remains in optimal operating condition, reducing additional costs caused by equipment failure.

[0028] In one specific embodiment of this application, the sum of the depth of the groove 2 from the circuit board and the height of the protrusion 3 is not less than the maximum height of the components in the corresponding area of ​​the test board. The groove 2 ensures sufficient safety space between the fixture body 1 and the high-protrusion components on the circuit board. The fixture in this embodiment employs non-destructive testing techniques such as visual inspection or non-contact measurement for different types of chips, which can protect the chips from physical damage and reduce the scrap rate.

[0029] In one specific embodiment of this application, the edge of the fixture body 1 is provided with multiple threaded through holes 5, and the fixture body 1 is connected to the test and label sorting machine platform by studs 4. Specifically, the edge area of ​​the fixture body 1 is provided with multiple threaded through holes 5 that are threadedly engaged with multiple studs 4, so that the fixture body 1, the circuit board under test, and the test socket are fixed to the test and label sorting machine platform from bottom to top by multiple studs 4. The stud connection can ensure the stability of the connection, while having low cost and allowing for quick installation and disassembly. The fixture is mainly used to support and fix the chip under test, and transmit signals to the test equipment through a reliable connection. Its design is usually more diversified to adapt to different functional and interface requirements. It is suitable for repeated precision testing, especially continuous testing in large-scale industrial production. The connection and fixation by studs 4 greatly improves the testing efficiency.

[0030] In one specific embodiment of this application, the threaded through-hole 5 is positioned on the fixture body 1 at a location corresponding to a non-sensitive area of ​​the test board, ensuring a safe distance between the stud 4 and the sensitive area of ​​the test board during connection. The main purpose of the test fixture is to repeat and accurately replicate a portion of the production process, improving productivity and making production equipment more precise. Specifically, in the microelectronics field, test fixtures have a wide range of applications, including mechanical fixtures and other fields. In microelectronics, the circuit board structure is relatively precise; the threaded through-hole 5 design effectively reduces the possible squeezing during fixture fixing, greatly improving safety.

[0031] In one specific embodiment of this application, the stud 4 includes a screw end 41 and a nut end 42. The outer diameter of the screw end 41 is not smaller than the outer diameter of the nut end 42, and the outer diameter of the nut end 42 is no greater than φ6mm, ensuring compatibility with other components. The length of the screw end 41 is greater than the sum of the thickness of the fixture body 1 at the threaded through hole 5 and the thickness of the test seat. The stud 4 is made of ABS plastic, which can both provide fastening and reduce costs, achieving the purpose of lightweighting. Specifically, in this embodiment, the screw end 41 uses an M4 screw, and the nut end 42 is embedded with a copper threaded sleeve 43. The copper threaded sleeve 43 is an M3 copper threaded sleeve, which is embedded in the plastic stud to improve thread durability and load-bearing capacity. The copper threaded sleeve is used for mounting, fixing, and locking the test seat. The combination of plastic and metal in the design balances lightweighting and structural strength.

[0032] In one specific embodiment of this application, when connecting the studs 4 to the threaded through holes 5, adhesive is used for fastening. Specifically, after tightening the fixture body 1, the circuit board under test, and the test seat onto the test and sorting machine platform from bottom to top using multiple studs 4, adhesive is used to secure the multiple studs 4 to the corresponding multiple threaded through holes 5. The fixture, as a core tool in the product testing process, focuses on accurately simulating the operating environment and conditions to efficiently verify the functionality, stability, and durability of products or components. It integrates customization and convenience, ensuring accurate execution of each test through precise design and material selection, thereby improving testing efficiency and quality. The connection and fixation of the fixture directly affect the accuracy of the test. Using adhesive for fastening further ensures the tightness of the connection. In this embodiment, a special adhesive is used to ensure a firm connection between components and prevent loosening.

[0033] A chip test fixture is a tool specifically designed for chip functional verification. Its main function is to assist test equipment in performing functional and reliability tests on chips under non-destructive conditions. It typically consists of conductive materials, insulating materials, mechanical structures, and precision connectors. In increasingly automated production lines, test fixtures have become a key component for achieving high-efficiency chip testing. The design and quality of the chip test fixture directly affect the accuracy and efficiency of the test. A well-designed test fixture ensures that the chip remains stable and electrically connected during testing, while effectively reducing wear and damage to the chip pins. Furthermore, by optimizing the fixture structure, the testing time for a single chip can be significantly shortened, thereby improving the efficiency of the entire production line.

[0034] This invention features an integrated structure that allows for quick and efficient installation of the test fixture. The integrated structure also facilitates debugging, rapid installation and disassembly, and high applicability. The use of plastic insulating material prevents short circuits and damage to electronic components on the circuit board. The use of bosses and recesses effectively avoids crushing electronic components on the circuit board. By matching the dimensions of the fixture body with the dimensions of the test fixture's mounting area, the size of the fixture body can be reduced, effectively improving applicability. Furthermore, the dimensions of the bosses and recesses correspond to the dimensions of the components in the test fixture's mounting area, further enhancing the fixture body's suitability for the circuit board and significantly improving the overall performance.

[0035] In one specific embodiment of this application, the usage process includes: pre-test preparation, where the test fixture needs to be installed and inspected before use to ensure it functions properly; the testing process, where appropriate fixtures can be selected based on the characteristics of different products to achieve fast and accurate testing; and the test results, where the test fixture can provide accurate test results, effectively improving product quality and ensuring product reliability.
