Abstract
Description
Technical Field
[0001] This invention belongs to the field of integrated circuit testing technology, and relates to a testing device and testing method. Background Technology
[0002] The quality of integrated circuit products determines the performance, reliability, and lifespan of terminal electronic devices. Even minor defects can affect the entire system, potentially causing economic losses or security risks. Therefore, after integrated circuit products are manufactured, quality testing is typically required to ensure product quality. Currently, the positioning blocks on the quality testing station are used for positioning the tested products. After the test board and test gold fingers required for testing are fixed, there is a certain amount of space between them and the fixed bottom. When there are differences in the position of the incoming materials in the testing station, differences in the pressure cover, or wear and deformation of the test gold fingers, after the tested product is pressed down and contacts the test gold fingers, the pins of the tested product material may get stuck on the test gold fingers and cannot be removed. This will cause the next tested product material to be unable to contact the test gold fingers when it enters the testing station for pressure testing, and the actual test result will still be the test result of the previous tested product material. Therefore, the test results of subsequent tested materials are exactly the same until the stuck material falls off the gold fingers. This situation may cause the manufacturer to mistakenly send defective products as good products into the tape reel to the customer, thus affecting the customer's use. Alternatively, after the test is completed, the tested product material may fall onto the positioning block due to the difficulty in picking it up, affecting the testing of the next material and thus affecting the testing efficiency.
[0003] Therefore, it is particularly urgent to develop a testing device that can improve testing efficiency and avoid misjudgment of test results for integrated circuit products. Summary of the Invention
[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a testing device and testing method to solve the problems of misjudgment of test results for integrated circuit products and low testing efficiency in the prior art.
[0005] To achieve the above and other related objectives, the present invention provides a detection device, comprising:
[0006] Equipment body;
[0007] The testing platform is fixed to the main body of the equipment;
[0008] A positioning and bearing mechanism includes an elastic platform, a positioning part, and an elastic lifting member. The elastic platform is disposed on the detection platform and can move in a direction away from and towards the upper surface of the detection platform. The positioning part is fixed to the platform of the elastic platform and includes at least a first part and a second part arranged at intervals along the X direction. The elastic lifting member is located between the first part and the second part and can move in a direction away from and towards the upper surface of the platform.
[0009] The detection mechanism is disposed on the detection platform on both sides of the elastic stage in the X direction, and the detection mechanism is used to detect the test item located on the elastic stage;
[0010] The detector includes a transmitter and a receiver respectively fixed on the detection platform. The light signal emitted by the transmitter can pass through the gap between the first part and the second part to reach the receiver.
[0011] Optionally, the elastic lifting member includes a lifting portion and a first elastic portion connected to the lifting portion, the lifting portion being movable in a direction away from and towards the upper surface of the platform.
[0012] Optionally, the platform has an opening adapted to the lifting part, and the bottom of the lifting part passes through the opening and is connected to the first elastic part below the opening.
[0013] Optionally, the elastic stage further includes a second elastic portion fixed below the platform, the second elastic portion being extendable and retractable in a direction away from and towards the upper surface of the detection platform.
[0014] Optionally, the testing platform has a through hole adapted to the platform; the bottom of the testing platform has a receiving part, the receiving cavity of the receiving part is connected to the through hole, the second elastic part is housed in the receiving cavity, and the top of the second elastic part is connected to the bottom of the platform.
[0015] Optionally, the top of the first part is provided with a first slot, and the top of the second part is provided with a second slot, both of which are adapted to the test sample.
[0016] Optionally, the detection device further includes a first bracket and a second bracket fixed to the detection platform, wherein the first bracket is detachably connected to the transmitting end and the second bracket is detachably connected to the receiving end.
[0017] Optionally, the first bracket is detachably connected to the testing platform; the second bracket is detachably connected to the testing platform.
[0018] Optionally, the main body of the device includes a control module electrically connected to the detector.
[0019] Optionally, the testing device further includes a support frame, the bottom of which is fixed to the main body of the device, and the top of which is connected to the testing platform.
[0020] The present invention also provides a detection method, which is performed by any of the devices provided above, and the method includes the following steps:
[0021] The transfer mechanism in the main body of the device transfers the test item to the first and second parts of the positioning unit, while the detector stops working.
[0022] The transfer mechanism presses down the test item, while simultaneously moving the elastic lifting member and the elastic platform in the positioning part toward the upper surface of the testing platform until the test item reaches the target position, and the device electrode of the test item contacts the testing electrode of the testing mechanism.
[0023] After the testing agency completes the testing of the test item, it sends feedback information to the processing module in the main body of the equipment.
[0024] The main body of the equipment controls the transfer mechanism to remove the test item from the positioning unit based on the received feedback information;
[0025] The main body of the device controls the detector to work. The transmitting end transmits a detection signal to detect whether the sample to be detected exists in the gap between the first part and the second part. If the detection signal received by the receiving end is abnormal, the main body of the device will sound an alarm and stop transferring the next sample to be detected. If the detection signal received by the receiving end is normal, the main body of the device will continue to transfer the next sample to be detected.
[0026] As described above, the present invention provides a detection device and a detection method, which have the following beneficial effects: The positioning and bearing mechanism, by setting a detector including a transmitting end and a receiving end on the detection platform, allows the light signal emitted by the transmitting end to pass through the gap between the first and second parts to reach the receiving end. When a test item is stuck on the detection mechanism or a test item has fallen onto the positioning part, the light signal received by the receiving end changes compared to the light signal received when there is no product on the positioning part and no test item is stuck on the detection mechanism. This facilitates timely detection of anomalies, avoids misjudgment of test results for the test item, and improves testing efficiency. Furthermore, by setting an elastic lifting member between the first and second parts, and allowing the elastic lifting member to move along the direction away from and towards the upper surface of the platform, after the detection is completed, the elastic lifting member, based on its elasticity, lifts the test item located on the positioning part, facilitating the transfer of the test item and improving testing efficiency.

[0045] This invention provides a detection device, such as... Figure 1 As shown, Figure 1 This is a schematic diagram of the detection device, which includes a main body 1, a detection platform 11, a positioning and bearing mechanism 2, a detection mechanism, and a detector 3. (The diagram shows the structure of the detection device.) Figure 2 and 3 As shown, Figure 2 and 3These are partial schematic diagrams of the testing device. The testing platform 11 is fixed to the main body 1 of the equipment. The positioning and bearing mechanism 2 includes an elastic platform 21, a positioning part 22, and an elastic lifting member 23. The elastic platform 21 is disposed on the testing platform 11 and can move in directions away from and towards the upper surface of the testing platform 11. The positioning part 22 is fixed to the platform 211 of the elastic platform 21. The positioning part 22 includes at least a first part 221 and a second part 222 arranged at intervals along the X direction (specifically as shown in the diagram). Figure 4 and 5 As shown, Figure 4 and 5 (Side view of positioning part 22 at different angles) The elastic lifting member 23 is located between the first part 221 and the second part 222 and the elastic lifting member 23 can move in the direction away from and close to the upper surface of the platform 211. The detection mechanism is set on the detection platform 11 on both sides of the elastic platform 21 in the X direction and is used to detect the test items located on the elastic platform 21. The detector 3 includes a transmitting end 31 and a receiving end 32 respectively fixed on the detection platform 11. The light signal sent by the transmitting end 31 can pass through the gap between the first part 221 and the second part 222 to reach the receiving end 32.
[0046] Specifically, while meeting the testing function, the specific structure and dimensions of the main body 1 can be selected according to actual needs. For example, the main body 1 is also provided with a storage module 12, a feeding module 13, a transfer mechanism 14, and a tape-and-reel module 15. The storage module 12 is used to store the test items, the transfer mechanism 14 is used to transfer the test items in the storage module 12 to the positioning part 22 through the feeding module 13 and to transfer the test items from the positioning part 22, and the tape-and-reel module 15 is used to pack the qualified test items that have passed the test.
[0047] Specifically, the test product refers to the integrated circuit product that needs to be tested.
[0048] Specifically, the specific structure, size and material of the testing platform 11 can be selected according to actual needs.
[0049] Specifically, the specific structure, size and material of the elastic platform 21 can be selected according to actual needs, and the thickness, plane size and material of the platform 211 can be selected according to actual needs.
[0050] Preferably, the elastic stage 21 further includes a second elastic part fixed below the platform 211, which can extend and retract in the direction away from and towards the upper surface of the detection platform 11.
[0051] Specifically, the material and size of the second elastic part can be selected according to actual needs. Based on the elastic effect of the second elastic part, the platform 211 can move in the direction away from the upper surface of the detection platform 11, and the platform 211 can also move in the direction close to the upper surface of the detection platform 11.
[0052] For example, a spring is used as the second elastic part. The top of the second elastic part abuts against or connects to the bottom of the platform 211. During testing, the suction cup in the transfer mechanism 14 places the test item on the positioning part 22 and presses down on the test item. The second elastic part is compressed by the downward force of the platform 211. The platform 211 moves downward, thereby driving the positioning part 22 to move downward (at this time, the downward movement of the platform 211 means that the platform 211 moves towards the upper surface of the detection platform 11) to the target position. After the test is completed, the suction cup no longer presses down on the test item. The suction cup needs to pick up the test item and move upward. Since the downward force of the suction cup on the test item disappears, the second elastic part extends, and the platform 211 moves upward, thereby driving the positioning part 22 to push the test item upward (at this time, the upward movement of the platform 211 means that the platform 211 moves away from the upper surface of the detection platform 11), thereby assisting the suction cup to pick up the test item located on the positioning part 22.
[0053] Specifically, the size, specific structure, and material of the positioning part 22 can be selected according to actual needs, wherein the X direction is any direction parallel to the upper surface of the detection platform 11. As long as the optical signal sent by the transmitting end 31 can completely pass through the gap between the first part 221 and the second part 222 to reach the receiving end 32, the distance between the first part 221 and the second part 222, the height of the first part 221, and the height of the second part 222 can be selected according to actual needs.
[0054] Preferably, the elastic lifting member 23 includes a lifting part and a first elastic part connected to the lifting part, the lifting part being movable in a direction away from and towards the upper surface of the platform 211.
[0055] Specifically, the material, size, and shape of the lifting part can be selected according to actual needs. For example, the lifting part is a cylinder; the material, size, and shape of the first elastic part can be selected according to actual needs, and the height of the top of the lifting part relative to the upper surface of the platform 211 can be set according to actual needs. It should be noted that, based on the elastic effect of the first elastic part, the lifting part can move in a direction away from the upper surface of the platform 211, and based on the elastic effect of the first elastic part, the lifting part can move in a direction close to the upper surface of the platform 211. The movement of the lifting part in the directions close to and away from the upper surface of the platform 211 refers to the movement of the top of the lifting part in the directions close to and away from the upper surface of the platform 211.
[0056] Preferably, the platform 211 has an opening adapted to the lifting part, and the bottom of the lifting part passes through the opening and is connected to the first elastic part below the opening.
[0057] Specifically, the shape and size of the opening can be selected according to actual needs. At the same time, as the lifting part moves away from and towards the upper surface of the platform 211 based on the elastic action of the first elastic part, the opening plays a guiding role for the lifting part.
[0058] For example, the first elastic part is a spring. The top of the first elastic part is fixed to the bottom of the platform 211, and the bottom of the first elastic part is sleeved and fixedly connected to the bottom of the lifting part. When testing the test item, the suction cup in the transfer mechanism 14 places the test item on the positioning part 22 and presses it down. The lifting part moves down under force (the lifting part moves down in the direction of moving towards the upper surface of the platform 211). The first elastic part is subjected to downward pressure and is in a stretched state. After the test is completed, the suction cup no longer exerts downward pressure on the test item. The suction cup needs to pick up the test item and move it upward. The first elastic part retracts due to the elastic effect. Based on the elastic force of the first elastic part, the lifting part moves upward accordingly (the lifting part moves upward in the direction of moving away from the upper surface of the platform 211), thereby generating an upward thrust on the test item. This provides an auxiliary function for the suction cup to pick up the test item located on the positioning part 22, thereby reducing the probability of the test item falling due to the unstable suction force of the suction cup on the test item.
[0059] Preferably, such as Figure 6 As shown, Figure 6 This is a schematic diagram of the testing platform 11. The testing platform 11 has through holes 212 that are adapted to the platform 211; the bottom of the testing platform 11 has a receiving part 4 (specifically as shown in the diagram). Figure 7 and 8 As shown), the receiving cavity 41 of the receiving part 4 is connected to the through hole 212, the second elastic part is housed in the receiving cavity 41, and the top of the second elastic part is connected to the bottom of the platform 211.
[0060] Preferably, the first elastic portion is housed in the receiving cavity 41.
[0061] Specifically, the second elastic part and the platform 211 can be welded together, detachably connected, or abutted together.
[0062] Specifically, the through hole 212 penetrates the upper and lower surfaces of the platform 211, and the shape and size of the through hole 212 can be selected according to actual needs. The size and shape of the receiving cavity 41 can be selected according to actual needs, and the size, shape and material of the receiving part 4 can be selected according to actual needs. The receiving part 4 can be detachably connected to the detection platform 11, or it can be welded to the detection platform 11.
[0063] Preferably, the top of the first part 221 is provided with a first slot 223, and the top of the second part 222 is provided with a second slot 224. Both the first slot 223 and the second slot 224 are adapted to the test sample.
[0064] Specifically, the shape and size of the first slot 223 and the second slot 224 must be adapted to the sample being tested. It should be noted that the first slot 223 and the second slot 224 are used together to position the sample being tested in a direction perpendicular to the X-direction. Furthermore, when no sample is placed on the positioning part 22, the height of the top of the lifting part relative to the platform 211 must be greater than the height of the bottom of the slot relative to the platform 211. The bottom of the slot refers to the bottom of either the first slot 223 or the second slot 224.
[0065] Specifically, the testing mechanism is set on the testing platform 11 and is located on both sides of the elastic stage 21 in the X direction. The size, dimensions and material of the testing mechanism can be selected according to actual needs.
[0066] In practical implementation, the specific structure of the testing mechanism needs to be determined according to the specific requirements of the testing project. Provided that the testing mechanism can perform normal testing on the test item located on the positioning part 22, the distance between the testing mechanism and the elastic stage 21 can be set according to actual needs. For example, the testing mechanism includes at least a test plate and two gold fingers electrically connected to the test plate. The two gold fingers serve as the testing electrodes of the testing mechanism for electrical contact with the test item to achieve testing. The two gold fingers are respectively distributed on both sides of the positioning part 22 in the X direction, and both gold fingers are located above the positioning part 22. The test plate is distributed on either side of the positioning part 22 in the X direction, and the test item stuck on the gold fingers remains in the gap between the first part 221 and the second part 222.
[0067] Specifically, the model and size of detector 3 can be selected according to actual needs, and the distance between transmitter 31 and receiver 32 can be selected according to actual needs. After the detection of the sample is completed, detector 3 starts to work, that is, transmitter 31 emits light signals. If the light signal received by receiver 32 is normal, it means that there is no sample on positioning part 22 or gold finger. If the light signal received by receiver 32 is abnormal, it means that there is sample on positioning part 22 or gold finger. Here, normal means that there is no sample blocking the gap between first part 221 and second part 222, and receiver 32 can fully receive the light signal emitted by transmitter. Abnormal means that because sample blocks the gap between first part 221 and second part 222, receiver 32 cannot receive light signal or the received light signal is weak.
[0068] Preferably, the detection device further includes a first bracket 33 and a second bracket 34 fixed on the detection platform 11. The first bracket 33 is detachably connected to the transmitting end 31, and the second bracket 34 is detachably connected to the receiving end 32.
[0069] Specifically, the size, material, and shape of the brackets (first bracket 33 and second bracket 34) can be selected according to actual needs. The shapes of the first bracket 33 and the second bracket 34 can be the same or different. The first bracket 33 is used to fix the transmitter 31, and the second bracket 34 is used to fix the receiver 32. For example, Figure 9 and 10 As shown, the first support 33 is in the shape of a "T", and the second support 34 is in the shape of a "T". Figure 9 and Figure 10 These are side views of the first bracket 33 and the second bracket 34, respectively.
[0070] Preferably, the first bracket 33 is detachably connected to the testing platform 11; the second bracket 34 is detachably connected to the testing platform 11.
[0071] For example, both the first bracket 33 and the second bracket 34 are provided with threaded through holes, and the testing platform 11 is provided with threaded openings that are adapted to the threaded through holes. The brackets (first bracket 33 and second bracket 34) are fixed on the testing platform 11 by screws connected to the threaded through holes and the threaded openings.
[0072] Preferably, the main body of the device 1 includes a control module electrically connected to the detector 3.
[0073] Specifically, the control module is used to control the working status of the transfer mechanism 14, the detector 3, and the detection mechanism.
[0074] Preferably, the main body 1 of the device further includes a processing module, which is used at least to receive, process and send information. In addition, the processing module, control module, detection mechanism, transfer mechanism 14 and detector 3 in the detection device of this application are electrically connected to each other and communicate with each other.
[0075] Preferably, the testing device further includes a support frame 5, the bottom of which is fixed to the main body 1 of the equipment, and the top of which is connected to the testing platform 11.
[0076] Specifically, the material, size, specific structure and shape of the support frame 5 can be selected according to actual needs.
[0077] Specifically, the positioning unit 22 includes at least a first part 221 and a second part 222 arranged at intervals along the X direction. The detector 3 includes a transmitter 31 and a receiver 32 respectively fixed on the detection platform 11. The light signal emitted by the transmitter 31 can pass through the gap between the first part 221 and the second part 222 to reach the receiver 32. When the test is completed, if a test item falls on the positioning unit 22 or a test item that has been tested is stuck on the detection mechanism near the positioning unit 22, the light signal received by the receiver 32 will be different from that when there is no test item on the positioning unit 22 and the detection mechanism is not in use. The change in the received light signal when there is no test item can be detected in time, thus improving the efficiency of testing and preventing misjudgment of the test results. By setting the elastic lifting member 23 between the first part 221 and the second part 222 and the elastic lifting member 23 being able to move in the direction away from and towards the upper surface of the platform 211, and the elastic platform 21, the test items located on the positioning part 22 can be subjected to a force away from the positioning part 22 based on the elastic effect after the test, which helps the test items to be transferred away from the positioning part 22 and reduces the probability of the test items falling.
[0078] Example 2
[0079] The present invention also provides a detection method, which is performed by any of the devices provided above, and the method includes the following steps:
[0080] Step S1: The transfer mechanism 14 in the main body of the equipment 1 transfers the test item to the first part 221 and the second part 222 of the positioning part 22, and at the same time the detector 3 stops working.
[0081] Specifically, the transfer mechanism 14 completes the corresponding actions based on the instructions sent by the control module from the main body of the equipment 1. For example, by rotating or moving, it can at least transfer the test items on the feeding module 13 to the first part 221 and the second part 222, and transfer the test items that have been tested on the first part 221 and the second part 222 to the tape module 15 or other positions. Other positions include, but are not limited to, positions for storing unqualified test items. The specific position information of other positions is selected according to actual needs.
[0082] Step S2: The transfer mechanism 14 presses down on the test sample, while simultaneously moving the elastic lifting member 23 and the elastic platform 21 in the positioning part 22 toward the upper surface of the test platform 11 until the test sample reaches the target position, and the device electrode of the test sample contacts the test electrode of the test mechanism.
[0083] Specifically, provided that the device electrodes of the test sample are in contact with the detection electrodes (e.g., gold fingers) of the detection mechanism to enable the detection mechanism to detect the test sample, the target position can be set according to actual needs.
[0084] Step S3: After the testing agency completes the testing of the test items, it sends feedback information to the processing module in the main body of the equipment 1.
[0085] Specifically, the processing module is electrically connected to and communicates with the testing organization, and the feedback information includes at least information indicating that the testing organization has completed the testing of the test item located on the positioning part 22. For example, the feedback information also includes the testing results of the testing organization on the test item, and the processing module determines whether the test item is qualified based on the testing results.
[0086] Step S4: Based on the received feedback information, the main body of the equipment 1 controls the transfer mechanism 14 to remove the test item from the positioning unit 22.
[0087] Specifically, the control module and the processing module are electrically connected and communicate with each other. After receiving feedback information, the processing module sends a processing command to the control module. The control module responds to the received processing command and controls the transfer mechanism 14 to complete the processing command to remove the inspection item from the positioning part 22. Under normal circumstances, the transfer mechanism 14 can remove the inspection item from the positioning part 22, the elastic platform 21 and the elastic lifting member 23 return to their normal state, and there is no obstruction between the gap between the first part 221 and the second part 222.
[0088] Step S5: The main body of the equipment 1 controls the detector 3 to work. The transmitting end 31 transmits a detection signal to detect whether there is a test item in the gap between the first part 221 and the second part 222. If the detection signal received by the receiving end 32 is abnormal, the main body of the equipment 1 will alarm and stop transferring the next test item. If the detection signal received by the receiving end 32 is normal, the main body of the equipment 1 will continue to transfer the next test item for detection.
[0089] Specifically, the detection signal is an optical signal, and the intensity of the optical signal emitted by the transmitting end 31 can be selected according to actual needs. For example, the condition for determining whether the detection signal is normal is as follows: the processing module in the main body 1 compares the preset detection signal information with the current detection signal information received by the receiving end 32 (the receiving end 32 sends the current detection signal information to the processing module). If the difference between the current detection signal information and the preset detection signal information is within a preset threshold range, the detection signal is normal; if the difference between the current detection signal information and the preset detection signal information exceeds the preset threshold range, the detection signal is abnormal. Here, the preset detection signal information refers to the relevant information (such as the optical signal intensity) of the optical signal received by the receiving end 32, provided that the elastic platform 21 and the elastic lifting member 23 are in a normal state (not in a compressed or stretched state) and the gap between the first part 221 and the second part 222 is not obstructed. The preset threshold range can be selected according to actual conditions. The current detection signal information refers to the relevant information (such as the optical signal intensity) of the optical signal currently received by the receiving end 32.
[0090] For example, if the detection signal received by the receiving end 32 is abnormal, the control module controls the transfer mechanism 14 to stop transferring the next detection item; if the detection signal received by the receiving end 32 is normal, the control module controls the transfer mechanism 14 to continue transferring the next detection item, that is, to start executing the above steps S1 and subsequent steps S4-5.
[0091] For example, the main body of the device 1 also includes an alarm module that is electrically connected to and communicates with the processing module. The alarm module is at least used to display the abnormal result of the detection signal. The abnormal result can be displayed in ways including but not limited to panel display, voice prompt, light alarm, or sending the abnormal result of the detection signal to a mobile terminal via wireless communication.
[0092] It should be noted that from the time the test item is transferred to the first part 221 and the second part 222 of the positioning unit 22, the test platform 11 tests the test item until the transfer mechanism 14 removes the test item from the positioning unit 22, during which time the detector 3 is in a stopped working state; after the transfer mechanism 14 completes the action of removing the test item from the positioning unit 22, the detector 3 starts working.
[0093] In summary, this invention provides a detection device and a detection method. The detection device includes a main body, a detection platform, a positioning and supporting mechanism, a detection mechanism, and a detector. The detection platform is fixed to the main body. The positioning and supporting mechanism includes an elastic platform, a positioning part, and an elastic lifting member. The elastic platform is disposed on the detection platform and can move in directions away from and towards the upper surface of the detection platform. The positioning part is fixed to the platform of the elastic platform and includes at least a first part and a second part arranged at intervals along the X direction. The elastic lifting member is located between the first part and the second part and can move in directions away from and towards the upper surface of the platform. The detection mechanism is disposed on the detection platform on both sides of the elastic platform in the X direction and is used to detect the test item located on the elastic platform. The detector includes a transmitting end and a receiving end respectively fixed on the detection platform. The light signal emitted by the transmitting end can pass through the gap between the first part and the second part to reach the receiving end. When a test item is stuck on the detection mechanism or a test item falls onto the positioning part, the abnormality can be detected in time based on the change in the light signal received by the receiving end, avoiding misjudgment of the test results of the test item and improving the testing efficiency. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
