Description

Technical Field

[0001] This utility model relates to the field of semiconductor packaging and testing, and in particular to a socket cleaning device. Background Technology

[0002] refer to Figure 1 and Figure 2 In the field of semiconductor packaging testing, the test socket (Socket 1) is a key component used to fix and connect chips during the testing process. Its internal cleanliness has a decisive impact on the accuracy of test results and product quality.

[0003] However, existing cleaning methods have many shortcomings. These methods typically rely on manual operation, such as cleaning with an air gun 5 every four hours. The frequency of cleaning lacks systematic control and alarm prompts, leading to frequent missed areas. Furthermore, the consistency of cleaning results is difficult to guarantee due to varying cleaning techniques among different operators. In particular, when using a brush 4, the small brush head makes it difficult to accurately locate and remove all dirt 3, resulting in some areas being uncleaned. Using an air gun 5 to blow air may disperse dirt 3 to other pins 2, causing new contamination. These problems not only reduce cleaning efficiency and effectiveness but may also affect the accuracy of test results, ultimately impacting the quality of the final product. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a socket cleaning device to solve the problems of lack of systematic control, inconsistent cleaning effect, reliance on manual cleaning methods, and potential secondary pollution caused by air gun blowing in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides a socket cleaning device, the cleaning device comprising:

[0006] Brush and suction integrated module and driver module;

[0007] The integrated brush and suction module includes a fixture body, several vacuum suction ports, and a brush assembly.

[0008] The fixture body has a mating surface that matches the outer periphery shape of the socket to be cleaned. When the mating surface of the fixture body is engaged with the socket, the mating surface completely covers the groove opening of the socket, thereby forming a sealed space with the groove opening of the socket. All the vacuum suction ports are disposed on the mating surface and communicate with the sealed space. The brush assembly includes a slide rail fixed to the fixture body and extending along the groove opening of the socket in a first direction, and a brush slidably mounted on the slide rail. The size of the brush in a second direction perpendicular to the first direction is equal to the size of the groove opening of the socket in the second direction.

[0009] The drive module is connected to the integrated brush and suction module and is used to drive the brush to reciprocate along the slide rail within the opening range of the groove.

[0010] Optionally, the socket is used for open-circuit / short-circuit testing.

[0011] Optionally, the planar dimensions of the mating surface of the fixture body are consistent with the planar dimensions of the socket.

[0012] Optionally, all the vacuum suction ports are evenly arranged on the mating surface corresponding to the groove opening.

[0013] Optionally, the outer perimeter of the Socket is rectangular, the first direction is the direction of the long side of the Socket, and the second direction is the direction of the wide side of the Socket.

[0014] Optionally, the vacuum suction port is connected to an external vacuum source via an air passage inside the fixture body.

[0015] Furthermore, it also includes a control module, which is connected to the drive module and the external vacuum source, and is used to start the drive module and the external vacuum source to perform the cleaning task when preset cleaning conditions are met.

[0016] Furthermore, the preset cleaning conditions include at least one of the following: current Lot test completion, continuous alarm, timed cleaning time arrival, and receipt of external manual cleaning command.

Specifically, the fixture body in the integrated brush and suction module has a mating surface that matches the outer shape of the socket to be cleaned. When the mating surface is engaged with the socket, it can completely cover the socket's groove opening and form a sealed space. Simultaneously, several vacuum suction ports are set on the mating surface and communicate with the sealed space, enabling timely removal of foreign objects during the cleaning process, further improving cleaning quality. Furthermore, the brush can reciprocate along the slide rail within the groove opening range. Its dimension perpendicular to the slide rail matches the dimension of the socket's groove opening, ensuring full contact between the brush and the socket surface, thereby achieving comprehensive cleaning of the socket surface and solving the problem of cleaning dead spots caused by incomplete cleaning coverage in traditional cleaning methods. The drive module provides power support for the reciprocating motion of the brush, making the entire cleaning process more automated and efficient. Furthermore, the cleaning frequency can be controlled in conjunction with the control module to form a systematic management system, reducing batch product anomalies caused by foreign objects, decreasing the frequency of retesting, and improving overall equipment efficiency (OEE) and output.

[0026] like Figure 3 and Figure 4 As shown, this utility model provides a socket cleaning device, the cleaning device comprising:

[0027] Brush and suction integrated module 10 and drive module (not shown);

[0028] The integrated brush and suction module 10 includes a fixture body 100, a plurality of vacuum suction ports 101, and a brush assembly 103;

[0029] The fixture body 100 has a mating surface 107 that matches the outer periphery shape of the Socket 11 to be cleaned. When the mating surface 107 of the fixture body 100 is engaged with the Socket 11, the mating surface 107 completely covers the groove opening 110 of the Socket 11, thereby forming a sealed space with the groove opening 110 of the Socket 11. All the vacuum suction ports 101 are disposed on the mating surface 107 and communicate with the sealed space. The brush assembly 103 includes a slide rail 104 fixed to the fixture body 100 and extending along the groove opening 110 of the Socket 11 in a first direction, and a brush 105 slidably mounted on the slide rail 104. The size of the brush 105 in a second direction perpendicular to the first direction is equal to the size of the groove opening 110 of the Socket 11 in the second direction.

[0030] The drive module is connected to the brush and suction integrated module 10 and is used to drive the brush 105 to reciprocate along the slide rail 104 within the groove opening 110.

[0031] This embodiment of the socket cleaning device achieves efficient cleaning of sockets and solves many problems existing in traditional cleaning methods through the design of an integrated brush and suction module. Specifically, the fixture body in the integrated brush and suction module has a mating surface that matches the outer shape of the socket to be cleaned. When the mating surface is engaged with the socket, it can completely cover the socket's groove opening and form a sealed space. At the same time, several vacuum suction ports are set on the mating surface and communicate with the sealed space, which can remove foreign objects in time during the brush cleaning process, further improving the cleaning quality. In addition, the brush can reciprocate along the slide rail within the groove opening range. Its dimension in the direction perpendicular to the slide rail matches the dimension of the socket groove opening, which can ensure that the brush and the socket surface make full contact, thereby achieving comprehensive cleaning of the socket surface and solving the problem of cleaning dead spots caused by incomplete cleaning range in traditional cleaning methods. The drive module provides power support for the reciprocating motion of the brush, making the entire cleaning process more automated and efficient. Therefore, this embodiment of the socket cleaning device, through its unique structural design and functional implementation, not only improves the cleaning quality of sockets but also enhances cleaning efficiency.

[0032] Specifically, the Socket 11 described in this embodiment is particularly suitable for application scenarios involving open-short circuit testing.

[0033] As an example, the planar dimensions of the mating surface 107 of the fixture body 100 are consistent with the planar dimensions of the Socket 11, so as to facilitate the fastening to form the sealed space and avoid vacuum leakage during cleaning, ensuring that the adsorption force is concentrated in the groove opening 110.

[0034] Furthermore, the outer periphery of the mating surface 107 of the fixture body 100 may be provided with an elastic sealing element, which is used to elastically abut against the outer periphery of the Socket 11 when fastened, so as to enhance the sealing of the sealed space and prevent foreign objects from leaking out. The manner of forming the sealed space is not limited to this embodiment.

[0035] Preferably, in this embodiment, all the vacuum suction ports 101 are uniformly arranged on the mating surface 107 corresponding to the groove opening 110, so that the negative pressure is basically uniformly distributed in the entire groove opening 110 area of ​​the Socket 11 during the cleaning process. The foreign objects swept up by the brush 105 can be carried away by the vacuum suction ports 101 at the same time, avoiding residue caused by insufficient local suction. At the same time, the uniform vacuum suction ports 101 eliminate airflow dead zones, preventing foreign objects from accumulating in dead corners or being carried by airflow and falling again onto the adjacent pins 111, thereby significantly improving the cleanliness and consistency of a single cleaning and shortening the cleaning time.

[0036] In this embodiment, the outer periphery of the Socket 11 is rectangular. The first direction is the long side direction of the Socket 11, and the second direction is the wide side direction of the Socket 11. As a result, the lateral span of the brush 105 is equal to the width of the groove opening 110, and its reciprocating stroke also exactly covers the entire long side length of the groove opening 110. Thus, the entire area of ​​the groove opening 110 can be swept in one back-and-forth motion.

[0037] As an example, the vacuum inlet 101 is connected to an external vacuum source (not shown) via an air passage 102 inside the fixture body 100.

[0038] Furthermore, as an example, the cleaning device also includes a control module connected to the drive module and the external vacuum source, used to activate the drive module and the external vacuum source to perform a cleaning task when preset cleaning conditions are met. Exemplarily, the preset cleaning conditions include at least one of the following: completion of the current batch (Lot) test, continuous alarm, arrival of the scheduled cleaning time, and receipt of an external manual cleaning command.

[0039] As a preferred example, the slide rail 104 is positioned at the middle of the fixture body 100 in the second direction, so that the reciprocating motion trajectory of the brush 105 falls on the central axis of the groove opening 110, thereby ensuring that the distance from both sides of the brush 105 to the sidewall of the groove opening 110 is equal, and maintaining uniform interference and brushing force throughout the entire stroke; this not only avoids excessive local wear or cleaning dead corners caused by offset installation, but also makes the vacuum suction port 101 symmetrically distributed on both sides of the brush 105 with balanced suction, so that dust and sticky foreign objects are synchronously rolled up and immediately sucked away, thereby improving cleaning consistency, extending the life of the brush 105, and reducing maintenance frequency.

[0040] As an example, the integrated brush and suction module 10 also has a mechanical interface 106 for docking with the robotic arm 12. The robotic arm 12 can move the integrated brush and suction module 10 above the socket 11 and fasten the integrated brush and suction module 10 onto the socket 11, and can also remove the integrated brush and suction module 10 from the socket 11 after cleaning. The integrated brush and suction module 10 can be quickly replaced according to the planar dimensions of the socket 11 without adjusting the machine, ensuring that different products achieve full-size fit and sealing and precise brushing and suction, avoiding cleaning dead corners of small heads and large covers or vacuum leakage of large covers and small heads, and taking into account the cleaning consistency of multi-product co-production scenarios.

[0041] In summary, this utility model's socket cleaning device, through its integrated brush and suction module design, achieves highly efficient cleaning of sockets and solves many problems inherent in traditional cleaning methods. Specifically, the fixture body in the integrated brush and suction module has a mating surface that matches the outer shape of the socket to be cleaned. When the mating surface is engaged with the socket, it completely covers the socket's groove opening and forms a sealed space. Simultaneously, several vacuum suction ports are located on the mating surface and communicate with the sealed space, enabling timely removal of foreign objects during the cleaning process, further improving cleaning quality. Furthermore, the brush can reciprocate along the slide rail within the groove opening area. Its dimensions perpendicular to the slide rail match the dimensions of the socket's groove opening, ensuring full contact between the brush and the socket surface, thereby achieving comprehensive cleaning of the socket surface and solving the cleaning blind spot problem caused by incomplete cleaning coverage in traditional cleaning methods. The drive module provides power support for the brush's reciprocating motion, making the entire cleaning process more automated and efficient. Furthermore, the cleaning frequency can be controlled through a linkage control module, forming a systematic management and control system. This reduces batch product anomalies caused by foreign objects, decreases the frequency of retesting, and improves overall equipment efficiency (OEE) and output. This cleaning device not only optimizes the cleaning scheme for Open Short test equipment but also significantly reduces the impact of foreign objects inside the socket on product quality, thereby greatly enhancing product quality, increasing production efficiency, and ultimately significantly improving production revenue. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
