Description

Technical Field

[0001] This utility model belongs to the field of electronic testing technology, and in particular relates to a SOCKET device and COMPASS testing equipment for improving the test item CPK. Background Technology

[0002] COMPASS chips integrated on FPCA (Flexible Printed Circuit Assembly) typically refer to electronic compass chips used to measure magnetic field direction or provide navigation functions. These chips are widely used in mobile devices, drones, smart wearable devices, and other scenarios that require direction awareness.

[0003] As consumer electronics products become increasingly complex and product quality requirements rise, the testing standards for COMPASS chips integrated into FPCA (Functional Circuit-on-Chip) systems are becoming more stringent. Current testing procedures must encompass both ICT (In-Circuit Testing) and FCT (Functional Testing), with functional testing of COMPASS components being particularly critical. This requires test equipment to provide a stable and uniform unipolar magnetic field environment, ensuring constant magnetic field strength while maintaining precise angular alignment between the magnetic field direction and the component. This places extremely high demands on the positioning accuracy and angle control of the product under test within the magnetic field space.

[0004] After testing, different products generate corresponding test parameters, and the stability and test consistency of the equipment are evaluated through CPK (Process Capability Index) analysis. The customer explicitly requires that the CPK value of all test items must exceed 2.0; however, existing equipment cannot meet this requirement due to the structural limitations of the socket. Therefore, a new socket structure is needed. Summary of the Invention

[0060] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0061] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0062] like Figure 1-6 As shown, in one embodiment, a socket device for improving the test item CPK is proposed, the socket device for improving the test item CPK includes:

[0063] The base plate 100 is provided with a first workstation 110 for placing products;

[0064] The needle mold assembly 200 is disposed on the base plate 100 and has a second station 210 for placing products, so that the first station 110 and the second station 210 are relatively independent;

[0065] The first limiting component 300 is disposed on one side of the needle mold component 200 and is used to limit the product within the first station 110.

[0066] The second limiting component 400 is disposed on the base plate 100 and is used to limit the needle mold component 200 and limit the product within the second station 210.

[0067] In this embodiment, as Figure 5 and 6 As shown, the base plate 100 is the base of the SOCKET device, and a plurality of limiting grooves are provided on one side of it. A plurality of product limiting blocks 140 are correspondingly installed in the limiting grooves. The product limiting blocks 140 together form the first station 110, which is used to place chip products, wherein the products are COMPASS components. A second station 210 is provided on one side of the first station 110. When the chip product is placed on the first station 110, the flexible board portion of the product will be placed into the second station 210. The probe assembly 200 is a B2B (board to board) test probe assembly, which can perform probe testing on the flexible board placed in the second station 210 and lead out the signal. The first limiting assembly 300 and the second limiting assembly 400 can both be mechanical fixing limiting devices, which fix the chip product by physical buckles, clamping mechanisms or rotation pressing structures, with the purpose of fixing the chip on the station.

[0068] In this embodiment, the first station 110 and the second station 210 are relatively independent. The first station 110 is set on the pin mold assembly 200 for pin piercing testing, and the second station 210 is set on the base plate 100 for positioning the COMPASS component. Previously, connector testing pin molds were relatively large and used to position the COMPASS component, but the product and component positions would move during connector testing, leading to inaccurate positioning accuracy. Pin piercing testing of the pin mold assembly requires relative movement between the product and the probe, which can easily cause mutual interference. Therefore, this embodiment separates the support and positioning of the B2B testing pin mold and the COMPASS component by setting relatively independent first stations 110 and second stations 210. COMPASS component testing requires the product to remain fixed in a designated position in space, without interference. Furthermore, this embodiment places the COMPASS component directly on the base plate 100, allowing direct control of processing errors in the Z-axis height positioning, maintaining good consistency in component position for each test. The CPK (Process Capability Index) test item refers to an indicator that uses statistical methods to evaluate whether the production process can consistently meet product quality specifications. It is primarily used to measure the stability and consistency of the manufacturing process, ensuring that product characteristics (such as size, weight, strength, etc.) meet the upper and lower limits specified by the design or customer. This embodiment, through a redesign of the SOCKET device structure, can stably improve the test data CPK. Market validation shows that the CPK of all test items can exceed 2, and some even exceed 40, demonstrating better stability.

[0069] In an optimization scheme, such as Figure 2 As shown, the needle mold assembly 200 includes:

[0070] Needle mold limiting block 220;

[0071] The first needle mold 230 is disposed at the bottom of the needle mold limiting block 220; the second work station 210 is disposed on the first needle mold 230;

[0072] The second needle mold 240 is disposed at the bottom of the first needle mold 230, fixed to the needle mold limiting block 220, and floatingly connected to the first needle mold 230;

[0073] The third needle mold 250 is disposed at the bottom of the second needle mold 240;

[0074] Probe 260 is disposed between the second needle mold 240 and the third needle mold 250, passes through the first needle mold 230, and is used to touch the product in the second station 210;

[0075] PCB board 270 is located at the bottom of the third pin mold 250 and is used to transfer the signal of probe 260.

[0076] In this optimized design, a pin mold limiting block 220 is positioned at the top to confine the first pin mold 230 between the pin mold limiting block 220 and the second pin mold 240. A second workstation 210 is provided on the first pin mold 230 for pin insertion testing. The first pin mold 230 and the second pin mold 240 are connected by an elastic element and a guide pin, allowing the first pin mold 230 to float up and down between the pin mold limiting block 220 and the second pin mold 240, enabling the probe 260 to insert into the contact of the B2B connector. The pin mold assembly 200 in this design is a modular structure, allowing the first workstation 110 and the second workstation 210 to be separable from each other.

[0077] In an optimization scheme, such as Figure 3 As shown, the first limiting component 300 includes:

[0078] The first rotating seat 310 is disposed on the base plate 100;

[0079] The first rotating pressure block 320 is rotatably connected to the first rotating seat 310 through the first rotating reset structure 330, and is used to press down the product in the second work station 210.

[0080] In this optimized scheme, the first rotating seat 310 is a steel sheet pressing block rotating seat, and the first rotating pressing block 320 is a steel sheet pressing block, which restricts the flexible plate in the second station 210 in the Z-axis direction. The first rotational reset structure 330 includes a rotating pin and a torsion spring. The rotating pin is inserted into the first rotating seat 310 and the first rotating pressing block 320, and the torsion spring is set in the rotating pin to play the role of rotational reset.

[0081] In an optimization scheme, such as Figure 4 As shown, the second limiting component 400 includes:

[0082] The second rotating seat 410 is disposed on the base plate 100;

[0083] The second rotating pressure block 420 is rotatably connected to the second rotating seat 410 through the second rotating reset structure 430, and is used to limit the first needle mold 230 on the top surface of the second needle mold 240 and limit the product within the first station 110;

[0084] The snap-fit ​​structure 440 is used to snap the second rotating pressure block 420 together with the base plate 100;

[0085] The first pressing block 450 is floatingly disposed on the second rotating pressing block 420, and is used to limit the first needle mold 230 to the top surface of the second needle mold 240.

[0086] The second pressure block 460 is floatingly disposed on the second rotating pressure block 420 and is used to limit the product within the first station 110.

[0087] The third pressure block 470 is disposed on the second rotating pressure block 420 and is used to limit the flexible plate around the product.

[0088] In this optimized scheme, the second rotating seat 410 is a flip-top rotating seat, and the second rotating pressing block 420 is entirely a flip-top, with a snap-fit ​​structure 440, a first pressing block 450, a second pressing block 460, and a third pressing block 470 disposed on its top. The second rotating reset structure 430 is the same as the first rotating reset structure 330, both including a rotating pin and a torsion spring, using the torsion of the torsion spring to achieve flipping and reset. The snap-fit ​​structure 440 can be a cantilever buckle, which can play a role in locking and fixing after the second rotating pressing block 420 is flipped. The first pressing block 450 is a needle mold pressing block, which limits the needle mold assembly 200 in the Z direction; wherein the first pressing block 450 is disposed inside the second rotating pressing block 420, and is limited by an elastic element and the needle mold pressing block sealing plate, so that the first pressing block 450 can float up and down in the Z-axis direction. The second pressure block 460 is a COMPASS pressure block used to fix the product in the Z-axis direction. The second pressure block 460 is located inside the second rotating pressure block 420 and is limited by an elastic element and the COMPASS pressure block sealing plate, thus achieving vertical floating. The third pressure block 470 is a product limiting pressure block, serving as an auxiliary limiting element.

[0089] In an optimization scheme, such as Figure 4 As shown, the snap-fit ​​structure 440 includes:

[0090] The buckle 441 is rotatably connected to the second rotating pressure block 420 via the buckle rotating pin 444;

[0091] Spring 442 is disposed between the buckle 441 and the second rotating pressure block 420;

[0092] A snap-fit ​​limiting block 443 is disposed on the base plate 100 and is used to engage with the snap-fit ​​441.

[0093] In this optimized design, the snap-fit ​​structure 440 is symmetrical, snapping onto the base plate 100 from two opposite directions to achieve positioning and fixation. The latch 441 can rotate around the latch rotating pin 444 within a certain angle, while the spring 442 acts as a reset mechanism during the rotation of the latch 441. This snap-fit ​​structure 440 design facilitates the operator's snap-fit ​​and fixation operations.

[0094] like Figure 7-9 As shown, in another embodiment, a COMPASS testing apparatus is proposed, the COMPASS testing apparatus comprising:

[0095] The SOCKET device for improving test item CPK as described in the above embodiments;

[0096] The equipment bracket 500 is used to connect the SOCKET device of the improved test item CPK and to transfer the test signal of the needle mold assembly 200;

[0097] The testing device is connected to the equipment bracket 500 and is used to test the SOCKET device on the equipment bracket 500.

[0098] In this embodiment, a first guide sleeve 120 and a second guide sleeve 130 are respectively provided on both sides of the base plate 100 of the SOCKET device. A positioning pin 530 is provided on the device bracket 500 for connecting the first guide sleeve 120 and the second guide sleeve 130. The SOCKET device is a component frequently operated and handled by hand. Considering that the majority of users of the device are women, this embodiment simplifies the structure, reducing the length and width dimensions of the SOCKET device, lowering the component weight, and making it easier for direct manual operation.

[0099] Furthermore, this embodiment can also achieve precise docking. When the SOCKET device is placed on the equipment bracket 500, it needs to be positioned. The guide bushing hole of the SOCKET device is adjusted to the center for better force distribution. The first guide sleeve 120 is a circular guide sleeve, closer to the personnel, and the second guide sleeve 130 is a U-shaped sleeve, away from the personnel. The positioning pin 530 on the equipment bracket 500 is at the appropriate height, and the components can be smoothly placed and removed without jamming.

[0100] The COMPASS testing equipment works by fixing the product at a specified angle and position within the machine, which requires high angular and positional accuracy. The machine generates a magnetic field of a certain direction and intensity. After the product is connected to the circuit, the COMPASS component provides feedback parameters based on the magnetic field environment, determining whether the product is qualified based on different test parameters. Existing SOCKET devices can generally meet yield requirements, but the CPK (Constant Payable) of many test items needs to simultaneously meet customer specifications. This places high demands on the consistency and stability of the testing positions for different products. To improve the CPK of the test data, this embodiment designed this SOCKET device. Market validation shows that the CPK of all test items can exceed 2, and some even exceed 40, demonstrating good stability.

[0101] In this embodiment, as Figure 9 As shown, the equipment bracket 500 includes:

[0102] SOCKET limiting plate 510 is connected to the base plate 100;

[0103] The adapter component 520 is disposed on the SOCKET limiting plate 510 and is used to transfer the detection signal of the needle mold assembly 200 to the test device.

[0104] A positioning pin 530 is provided on the SOCKET limiting plate 510 and is used to connect the first guide sleeve 120 and the second guide sleeve 130.

[0105] A guide block 540 is disposed on the SOCKET limiting plate 510, and a ball head post for fixing the SOCKET device is provided on the guide block 540.

[0106] In this embodiment, the adapter component 520 specifically includes a bracket adapter PCB board, an adapter pin module, and an adapter probe, which are arranged sequentially from top to bottom for signal conversion.

[0107] The working principle of this embodiment is as follows:

[0108] The SOCKET device is movable, and the device bracket 500 can be removed for loading and unloading. Before testing, the second rotating pressure block 420 is opened via the latch 441, and the first rotating pressure block 320 is pressed down by hand. The product is placed into the first station 110 of the base plate 100, and then the first rotating pressure block 320 is released. The first rotating pressure block 320 presses down on the product under the action of the torsion spring, at which point the product is completely limited. Next, the second rotating pressure block 420 is rotated to close it. The latch 441 of the second rotating pressure block 420 engages with the latch limiting block 443. The first pressure block 450 on the second rotating pressure block 420 presses the first needle mold 230 onto the surface of the second needle mold 240. The probe 260 in the second needle mold 240 is inserted into the point of the product connector. The elastic second pressure block 460 presses down on the product component, and the component is completely limited. The assembly of the SOCKET device is completed.

[0109] Then, the SOCKET device is placed onto the SOCKET limiting plate 510 of the equipment bracket 500. The positioning pin 530 of the SOCKET limiting plate 510 mates with the first guide sleeve 120 and the second guide sleeve 130 on the SOCKET device for positioning. The guide block 540 facilitates manual operation to place it in the accurate position, and a ball-head plunger in the guide block 540 fixes the SOCKET device. One end of the adapter pin module on the SOCKET limiting plate 510 is attached to the PCB board on the SOCKET device, and the other end is attached to the point on the bracket adapter PCB board. The bracket adapter PCB board is connected to the test board in the testing device via a ribbon cable. Press the start button of the testing device to start the test. After the test is completed, remove the SOCKET device from the machine and start the cycle.

[0110] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0111] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
