[0036] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein.

[0037] This utility model embodiment provides a positioning triangle ruler, which is installed in a product testing system. Figure 1 This is a structural block diagram of a product testing system provided in an embodiment of this utility model. Figure 2 This is a schematic diagram illustrating the use of a positioning triangle ruler to position a target product in a manufacturing carrier, as provided in this embodiment of the utility model. (Refer to...) Figure 1 and Figure 2 The product testing system includes a testing device 100 and a positioning triangle 200. The positioning triangle 200 is used to position the target product on the manufacturing carrier 50 after the testing device 100 has tested the manufacturing carrier 50. The positioning triangle 200 includes:

[0038] The set square body includes a first arm 11 extending along a first direction and a second arm 12 extending along a second direction; wherein the first direction and the second direction are perpendicular to each other.

[0039] The first laser unit 21 is located on the first rudder arm 11;

[0040] The second laser unit 22 is located on the second foot arm 12.

[0041] Specifically, the extension direction of the first ruler arm 11 is perpendicular to the extension direction of the second ruler arm 12. The first ruler arm 11 can be used as the X-axis of the set square body, and the second ruler arm 12 can be used as the Y-axis of the set square body. Alternatively, the first ruler arm 11 can be used as the Y-axis of the set square body, and the second ruler arm 12 can be used as the X-axis of the set square body. The surfaces of the first ruler arm 11 and the second ruler arm 12 can be provided with scale values ​​for measuring length. The measuring range and scale division of the first ruler arm 11 and the second ruler arm 12 can be set according to actual needs. Alternatively, the surfaces of the first ruler arm 11 and the second ruler arm 12 may not be provided with scale values ​​for measuring length.

[0042] A first laser unit 21 is disposed on the first ruler arm 11 and can move along the first ruler arm 11; a second laser unit 22 is disposed on the first ruler arm 11 and can move along the second ruler arm 12. The first laser unit 21 emits a laser beam into the measurement area of ​​the triangle ruler body, and the laser beam emitted by the first laser unit 21 propagates along a second direction. The second laser unit 22 emits a laser beam into the measurement area of ​​the triangle ruler body, and the laser beam emitted by the second laser unit 22 propagates along a first direction. After the testing equipment 100 tests the manufacturing carrier 50, the positioning triangle ruler 200 moves to the manufacturing carrier 50. The first laser unit 21 and the second laser unit 22 in the positioning triangle ruler 200 move along their respective ruler arms to their respective target positions. At this time, the intersection of the laser beams emitted by the first laser unit 21 and the second laser unit 22 is the location of the target product, thereby locating the target product from the manufacturing carrier 50. The manufacturing carrier 50 includes multiple products 51 arranged in an array. The target product is the product 51 that needs to be located in the manufacturing carrier. For example, the target product is the product 51 that is determined to be defective after being tested by the testing equipment 100.

[0043] The technical solution provided by this utility model adds a positioning triangle ruler 200 to the product testing system. After the test is completed, without moving the manufacturing carrier 50, the positioning triangle ruler 200 is controlled to move around the manufacturing carrier 50 to locate the target product on the manufacturing carrier 50. This can quickly and accurately find the position of a certain material in the entire manufacturing carrier 50, replacing the method of manually locating the target product by counting the row and column of the target product in related technologies, thereby improving the production quality and efficiency of the product.

[0044] Based on the above embodiments, refer to Figure 1 and Figure 2 Optionally, the positioning triangle also includes a drive unit 30; the drive unit 30 is used to receive a first drive command generated by the control module 40, and after receiving the first drive command, drives the first laser unit 21 and the second laser unit 22 to move along their respective ruler arms to their respective target positions, and the intersection of the laser emitted by the first laser unit 21 and the laser emitted by the second laser unit 22 is used to position the target product.

[0045] Specifically, after the testing equipment 100 tests the manufacturing carrier 50, the positioning triangle 200 moves to the manufacturing carrier 50. The drive unit 30 in the positioning triangle 200 receives the first drive command sent by the control module 40, and after receiving the first drive command, drives the first laser unit 21 and the second laser unit 22 to move along their respective ruler arms to their respective target positions. At this time, the intersection of the laser emitted by the first laser unit 21 and the laser emitted by the second laser unit 22 is the position of the target product, thereby locating the target product from the manufacturing carrier 50.

[0046] Based on the above embodiments, refer to Figure 2 In one embodiment of this utility model, the manufacturing carrier 50 includes a wafer 501, and the target product is a defective grain identified by the testing equipment 100.

[0047] Specifically, wafer 501 is the array carrier in the semiconductor device manufacturing stage. Wafer 501 is a core basic material in semiconductor manufacturing, typically referring to an ultra-thin, high-purity circular silicon wafer (or other semiconductor materials, such as silicon carbide, gallium arsenide, etc.), whose surface can be fabricated into multiple independent dies (bare chips) through a series of complex processes. Testing equipment 100 is used to inspect wafer 501 to identify defective dies within it. After testing wafer 501 by testing equipment 100, a positioning triangle 200 moves to wafer 501. The driving unit 30 in the positioning triangle 200 receives a first driving command from the control module 40 and, upon receiving the first driving command, drives the first laser unit 21 and the second laser unit 22 to move along their respective ruler arms to their target positions. The intersection of the laser emitted by the first laser unit 21 and the second laser unit 22 at this point is the location of the defective die in wafer 501.

[0048] Based on the above embodiments, Figure 3 This is a schematic diagram illustrating the use of a positioning triangle ruler to position a target product in a manufacturing carrier, as provided in another embodiment of this utility model. (Refer to...) Figure 3 In another embodiment of the present invention, the manufacturing carrier 50 includes a packaging substrate 502, and the target product is a defective packaging unit identified by the testing equipment 100.

[0049] Specifically, the packaging substrate 502 (Strip) is an array carrier in the semiconductor device packaging stage. It receives bare chips cut from wafer 501 and packages them into individual finished products; multiple packaging units are carried on the packaging substrate 502. Through the packaging substrate 502, the packaging steps (die placement, bonding, molding, etc.) of multiple bare chips can be completed simultaneously, improving chip packaging efficiency. The testing equipment 100 is used to inspect the packaging substrate 502 to identify defective packaging units within it. After the testing equipment 100 tests the packaging substrate 502, a positioning triangle 200 is moved to the packaging substrate 502. After the positioning triangle 200 moves to the packaging substrate 502, the driving unit 30 in the positioning triangle 200 receives the first driving command from the control module 40, and drives the first laser unit 21 and the second laser unit 22 to move along their respective ruler arms to their respective target positions. At this time, the intersection of the laser emitted by the first laser unit 21 and the laser emitted by the second laser unit 22 is the position of the defective packaging unit in the packaging substrate 502.

[0050] Based on the above embodiments, refer to Figures 1-3 Optionally, the positioning triangle 200 also includes a control module 40, which is disposed within the positioning triangle 200 and is a component thereof. The control module 40 is fixed to the side of the first arm 11 away from the manufacturing carrier 50, and / or fixed to the side of the second arm 12 away from the manufacturing carrier 50. The control module 40 is electrically connected to the drive unit 30 to send a first drive command to the drive unit 30. Figure 2 and Figure 3 The control module 40 is shown, by way of example, fixed to the side of the second arm 12 away from the manufacturing carrier 50.

[0051] Based on the above embodiments, Figure 4 This is a structural block diagram of another product testing system provided in this embodiment of the present invention, for reference. Figure 4 Optionally, the product testing system also includes a control terminal 300 connected to the testing equipment 100; the control terminal 300 is used to control the working status of the testing equipment 100, and the control terminal 300 and the positioning triangle ruler 200 are set up independently; the control terminal 300 is reused as a control module 40, that is, the control module 40 and the positioning triangle ruler 200 are set up independently. The control terminal 300 can be a display terminal such as a computer, tablet, or mobile phone.

[0052] Based on the above embodiments, Figure 5 This is a structural block diagram of a control module 40 provided in an embodiment of the present invention, with reference to... Figure 5 Optionally, the control module 40 includes:

[0053] Information receiving unit 410 is used to receive the test coordinates of the target product and the size information of the target product;

[0054] The information processing unit 420 is connected to the information receiving unit 410. After receiving the test coordinates and size information of the target product, the information processing unit 420 outputs the target position information of the target product. The two coordinate values ​​in the test coordinates are the row coordinates and column coordinates of the target product in the manufacturing carrier 50, respectively. The target position information includes the distance of the target product relative to the origin of the coordinates in the first direction and the distance of the target product relative to the origin of the coordinates in the second direction.

[0055] The instruction sending unit 430 is electrically connected to the information processing unit 420 and the drive unit 30. The instruction sending unit 430 is used to receive target location information and generate drive instructions after receiving the target location information, and send them to the drive unit 30.

[0056] Specifically, after testing the manufacturing carrier 50, the testing equipment 100 can obtain the coordinates (i.e., test coordinates) of the position of the defective product (target product) in the manufacturing carrier 50. The two coordinate values ​​in the test coordinates are the row and column coordinates of the target product in the manufacturing carrier 50. The position of the product in the first column of the manufacturing carrier 50 can be used as the position of the X-axis of the test coordinate system with 0, and the position of the product in the first row of the manufacturing carrier 50 can be used as the position of the Y-axis of the test coordinate system with 0. For example, if the test coordinates of a defective product in the manufacturing carrier 50 are (6, 8), the column coordinate is 6, and the row coordinate is 8, then the position of the defective product in the manufacturing carrier 50 is the 7th column and the 9th row. To improve the problem of easily miscounting the position when manually counting the 7th column and the 9th row, this embodiment of the invention uses the control module 40 to control the positions of the first laser unit 21 and the second laser unit 22 on the first ruler arm 11 and the second ruler arm 12, respectively, based on the test coordinates and size information of the target product, thereby achieving the positioning of the target product.

[0057] The control module 40 includes an information receiving unit 410, an information processing unit 420, and an instruction sending unit 430. The information receiving unit 410 is used to receive the test coordinates and size information of the target product. The information processing unit 420 is connected to the information receiving unit 410 and is used to output the target position information of the target product after receiving the test coordinates and size information of the target product.

[0058] For example, the first ruler arm 11 serves as the X-axis of the set square body, and the second ruler arm 12 serves as the Y-axis of the set square body. The dimensions of the product carried on the manufacturing carrier 50 are: length 1.60 mm and width 1.25 mm; wherein the length of the product 51 is the dimension of the product 51 on the first ruler arm 11, and the width is the dimension of the product 51 on the second ruler arm. The dimensions of the products 51 on the same manufacturing carrier 50 are the same.

[0059] In the positioning coordinate system formed by the first and second arms of the triangle ruler body, the intersection of the extension line of the first column of products in the manufacturing carrier 50 with the X-axis of the positioning coordinate system is the position where the X-axis coordinate is 0, and the intersection of the extension line of the first row of products in the manufacturing carrier 50 with the Y-axis of the positioning coordinate system is the position where the Y-axis coordinate is 0. The target position of the first laser unit 21 on the first arm 11 is the position corresponding to the column coordinate of the target product multiplied by the size of product 51 on the first arm 11; the target position of the second laser unit 22 on the second arm 12 is the position corresponding to the row coordinate of the target product multiplied by the size of product 51 on the second arm 11. The target position of the first laser unit 21 on the first ruler arm 11 is the position on the first ruler arm 11 at a distance of 6*1.60mm=9.60mm from the origin of the X-axis of the positioning coordinate system. The target position of the second laser unit 22 on the second ruler arm 12 is the position on the second ruler arm 11 at a distance of 8*1.25mm=10.00mm from the origin of the Y-axis of the positioning coordinate system.

[0060] The instruction sending unit 430 sends a first driving instruction to the driving unit 30, so that the driving unit 30 controls the first laser unit 21 to move to the position corresponding to the distance of 9.60mm from the X-axis origin of the positioning coordinate system of the first ruler arm 11, and controls the second laser unit 22 to move to the position corresponding to the distance of 10.00mm from the X-axis origin of the positioning coordinate system of the second ruler arm 12. At this time, the intersection of the laser emitted by the first laser unit 21 and the laser emitted by the second laser unit 22 is the position of the target product with test coordinates (6, 8).

[0061] It should be noted that when scale values ​​are set on the first and second arms of the set square, the origin of each axis in the set square's positioning coordinate system can be the same as or different from the origin of the actual measurement coordinate system formed by the scale values ​​on the arms of the set square; however, the Y-axis in the set square's positioning coordinate system is parallel to the Y-axis in the actual measurement coordinate system, and the X-axis in the set square's positioning coordinate system is parallel to the X-axis in the actual measurement coordinate system.

[0062] Optionally, based on the above embodiments, the control module 40 further includes:

[0063] The positioning coordinate system storage unit and the positioning coordinate system establishment unit are used to store the current position information of the first laser unit 21 on the first ruler arm after the first laser unit 21 is moved to the position aligned with the first column of products in the current manufacturing carrier 50, and to store the current position information of the second laser unit 22 on the second ruler arm after the second laser unit 22 is moved to the position aligned with the first row of products in the current manufacturing carrier 50.

[0064] Specifically, before the first positioning of the target product in the manufacturing carrier 50, the position of the first laser unit 21 on the first ruler arm 11 can be adjusted so that the laser emitted by the first laser unit 21 is aligned with the first column of products in the manufacturing carrier 50 near the side extending along the second direction, for example, aligned with the rightmost column in the manufacturing carrier 50. This is confirmed as the position where the X-axis coordinate of the triangle ruler is 0, which is the initial position of the first laser unit 21. The position of the second laser unit 22 on the second ruler arm 12 can be adjusted so that the laser emitted by the second laser unit 22 is aligned with the first row of products in the manufacturing carrier 50 near the side extending along the first direction, for example, aligned with the bottommost row in the manufacturing carrier 50. This is confirmed as the position where the Y-axis coordinate of the triangle ruler is 0, which is the initial position of the second laser unit 22. The positioning coordinate system storage unit is used to save the current position information of the first laser unit 21 on the first ruler arm and the current position information of the second laser unit 22 on the second ruler arm, thereby determining the initial positions of the first laser unit 21 and the second laser unit 22.

[0065] Based on the above embodiments, optionally, the driving unit 30 is further configured to receive a second driving command generated by the control module 40, and after receiving the second driving command, drive the first laser unit 21 and the second laser unit 22 to move along their respective ruler arms to the position of the origin of the triangular positioning coordinate system.

[0066] Specifically, for 200 pairs of positioning triangles Figure 2In the case where positioning of the dies in wafer 501 is required, and multiple target dies in wafer 501 need to be positioned, the information receiving unit 410 can also receive the coordinate information of the origin of the test coordinate system, i.e., the test coordinate (0, 0) in the manufacturing carrier 50, during the second or subsequent positioning of the target dies. The instruction sending unit 430 generates a second driving instruction based on the received coordinate information of the origin of the test coordinate system and sends it to the driving unit 30. The driving unit 30 can also receive the second driving instruction generated by the control module 40, and after receiving the second driving instruction, drive the first laser unit 21 and the second laser unit 22 to move along their respective ruler arms. After the first laser unit 21 and the second laser unit 22 stop moving along their respective ruler arms, it can be visually determined whether the position of the laser intersection point of the first laser unit 21 and the second laser unit 22 is the position of the test coordinate (0, 0), thereby realizing the determination of whether the positioning triangle ruler 200 has moved to the preset target position. If the position of the laser intersection point of the first laser unit 21 and the second laser unit 22 is not the position of the test coordinate (0, 0), then the position of the adjustment positioning triangle 200 relative to the manufacturing carrier 50 needs to be corrected.

[0067] Optional, Figure 6 This is a schematic diagram of another positioning triangle provided in an embodiment of the present invention, for reference. Figure 6 When the control module 40 is set in the positioning triangle ruler 200, the information receiving unit 410 can be a button unit 401 set on the surface of the control module 40, or a touch screen 402 set on the surface of the control module 40. The test coordinates and size information of the target product are received through the button unit 401 or the touch screen 402.

[0068] Based on the above embodiments, refer to Figure 6 Optionally, the first laser unit 21 includes a first slider and a first laser 211 fixed on the first slider; the first slider is used to drive the first laser to move on the first ruler arm 11; the second laser unit 22 includes a second slider and a second laser 221 fixed on the second slider; the second slider is used to drive the second laser to move on the second ruler arm 12.

[0069] The driving unit 30 includes a first driving subunit for driving the first laser unit 21 and a second driving subunit for driving the second laser unit 22. Both the first and second driving subunits include a conveyor belt and a motor for driving the conveyor belt to rotate. A first slider is disposed on the conveyor belt in the first driving subunit, and the conveyor belt in the first driving subunit can drive the first slider to move when the motor rotates. A second slider is disposed on the conveyor belt in the second driving subunit, and the conveyor belt in the second driving subunit can drive the second slider to move when the motor rotates. The control module 40 is used to control the working state of the motor. The first ruler arm 11 is also provided with a first slide groove 212, in which the first slider is located and slides. The second ruler arm 12 is also provided with a second slide groove 222, in which the second slider is located and slides.

[0070] refer to Figure 1 and Figure 4 This utility model embodiment also provides a product testing system, including: a testing device 100 and a positioning triangle 200 as described in any embodiment of this utility model. The testing device 100 is used to identify the target product in the manufacturing carrier 50, and the positioning triangle 200 is used to move to the manufacturing carrier 50 to position the target product on the manufacturing carrier 50 after the testing device 100 has tested the manufacturing carrier 50. It has the same technical effects and will not be described again here.
