Description

Technical Field

[0001] The present application relates to the technical field of acupuncture pressure testing, and in particular to an acupuncture pressure testing module and quality inspection equipment. Background Art

[0002] At present, in some industries, in order to ensure the performance of the products produced, it is necessary to conduct quality inspection through needle pressure testing technology. For example, in the field of semiconductors, wafer production is a relatively important link. The quality of the wafer will directly affect the performance of the semiconductor. For this reason, it is necessary to conduct quality inspection on the wafer after the wafer production is completed. In the quality inspection of the wafer, there is a needle pressure test link, which requires the use of a probe to perform electrical testing on the chip (Di e) on the wafer; for another example, in the field of surface mount technology (Surface Mounted Technology, SMT), in order to ensure the quality of the integrated circuit (Integrated Circuit, IC) or assembled printed circuit board (PCBA), it is necessary to use a probe to perform electrical testing on the unit under test (IC or PCBA) on the IC or PCBA.

[0003] During the needle pressure test, in order to ensure that the pressure applied by the probe to the measured unit such as a chip, IC, PCBA, etc. does not damage the current measured unit, the needle pressure of the probe needs to be measured and monitored. The general needle pressure measurement of the probe is achieved by setting a strain sensor on the measuring body, and the needle pressure test is performed based on the strain effect. However, the deformation of the strain sensor is limited. When the probe is installed on the measuring body or there is a large difference in the height of the electrode of the measured unit, the measuring body will undergo a large deformation, and this deformation often causes the strain sensor to deform beyond its own deformation limit, causing damage to the strain sensor and affecting the efficiency of the needle pressure test.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0041] During the needle pressure test of the unit under test, in order to ensure that the pressure applied by the probe to the unit under test does not damage the current unit under test, the needle pressure of the probe needs to be measured and monitored. The general needle pressure measurement of the probe is achieved by setting a strain sensor on the measuring body, and the needle pressure test is performed based on the strain effect. However, the deformation of the strain sensor is limited. When the probe is installed on the measuring body or there is a large difference in the height of the electrodes in the unit under test, the measuring body will undergo a large deformation, and this deformation often causes the strain sensor to deform beyond its own deformation limit, causing damage to the strain sensor and affecting the efficiency of the needle pressure test.

[0042] In order to reduce the damage of the strain sensor caused by excessive deformation of the strain sensor, the embodiment of the present application provides a needle pressure test module and a quality inspection device, the needle pressure test module includes: a measuring part, including a through slot, the through slot is arranged in the horizontal direction of the measuring part; a connecting seat, used to install the first end of the measuring part; a probe part, installed at the second end of the measuring part; a limiting part, the first end of the limiting part is arranged at the first end of the through slot, the second end of the limiting part is suspended in the through slot, and the second end of the limiting part is used to limit the deformation of the measuring part in the vertical direction; a strain sensor, which is arranged on the surface of the measuring part in the vertical direction. By setting the limiting part to limit the deformation of the measuring body, the deformation of the strain sensor caused by the deformation of the measuring body can also be limited, so that the deformation of the strain sensor can be limited within the deformation limit of the strain sensor, and then the damage of the strain sensor caused by excessive deformation of the strain sensor can be reduced.

[0043] Reference Figure 1 As shown, Figure 1 The needle pressure test module 1 may include, but is not limited to, a measuring unit 11 , a connecting seat 12 , a probe unit 13 , a stopper 14 and a strain sensor 15 .

[0044] The measuring part 11 may include a through groove 111, which may be arranged in the horizontal direction of the measuring part 11, the connecting seat may be used to install the first end of the measuring part 11, the probe part may be installed at the second end of the measuring part 11, and the strain sensor 15 may be arranged on the surface of the measuring part 11 in the vertical direction.

[0045] Among them, the first end and the second end of the measuring part 11 are opposite ends, and do not specifically refer to the left end or the right end of the measuring part 11. For example, when the first end of the measuring part 11 is the left end of the measuring part 11, the second end of the measuring part 11 is the right end of the measuring part 11, and when the first end of the measuring part 11 is the right end of the measuring part 11, the second end of the measuring part 11 is the left end of the measuring part 11, which is not specifically limited here. In addition, the surface of the measuring part 11 in the vertical direction can be the upper surface of the measuring part 11 in the vertical direction, or it can be the lower surface of the measuring part 11 in the vertical direction, which is not specifically limited here. In addition, the number of strain sensors 15 arranged on the surface of the measuring part 11 in the vertical direction can be 1, 2, 3, etc., and those skilled in the art can choose according to actual conditions, which is not specifically limited here. In addition, the measuring part 11 can be made of metal material or insulating material, which is not specifically limited here.

[0046] The first end of the limiting portion 14 can be set at the first end of the limiting portion 14 set at the first end of the through slot 111, and the second end of the limiting portion 14 is suspended in the through slot 111. The second end of the limiting portion 14 can be used to limit the deformation of the measuring portion 11 in the vertical direction. Among them, the length of the through slot 111 can be various, for example, the length of the through slot 111 can be 60%, 70%, etc. of the length of the measuring portion 11. Those skilled in the art can choose according to actual conditions, and it is not specifically limited here. In addition, the second end of the limiting portion 14 suspended in the through slot 111 can be the second end of the limiting portion 14 suspended upward in the through slot 111, or it can be the second end of the limiting portion 14 suspended downward in the through slot 111, and it is not specifically limited here. In addition, the distance between the second end of the limiting portion 14 and the second end of the through slot 111 is various, and those skilled in the art can set it according to the deformation limit of the strain sensor, and it is not specifically limited here.

[0047] In addition, the first end of the through slot 111 may be on the same side as the first end of the measuring portion 11 , or on the opposite side of the first end of the measuring portion 11 , which is not specifically limited herein.

[0048] For example, refer to Figure 2 As shown, Figure 2A schematic diagram of the deformation of the measuring body in the needle pressure testing module is shown. When the first end of the through slot 111 is on the same side as the first end of the measuring part 11, the first end of the limiting part 14 is on the same side as the connecting seat 12, and the second end of the limiting part 14 is on the same side as the probe part 13 and is suspended in the air. When the measuring part 11 is subjected to an external force and deforms in the vertical direction exceeding the deformation limit of the strain sensor 15, the inner wall of the through slot 111 at one end of the probe part 13 (i.e., the second end of the through slot 111) will touch the second end of the limiting part 14. At this time, the measuring part 11 cannot continue the subsequent deformation due to the obstruction of the second end of the limiting part 14, so that the influence of excessive deformation on the strain sensor 15 can be reduced.

[0049] For another example, when the first end of the through slot 111 is on the opposite side of the first end of the measuring part 11, the first end of the limiting part 14 is on the same side as the probe part 13, and the second end of the limiting part 14 is on the same side as the connecting seat 12 and is suspended in the air. When the measuring part 11 is subjected to an external force and is deformed in the vertical direction exceeding the deformation limit of the strain sensor 15, the inner wall of the through slot 111 at one end of the connecting seat 12 (the second end of the through slot 111) will touch the second end of the limiting part 14. At this time, the measuring part 11 cannot continue the subsequent deformation due to the obstruction of the second end of the limiting part 14, so that the influence of excessive deformation on the strain sensor 15 can be reduced.

[0050] In one embodiment, the needle pressure test module 1 may further include a contact portion 16 and a warning portion 17. The contact portion 16 may be disposed at the second end of the through slot 111. The contact portion 16 may be an integrated "U-shaped contact piece", and the "U-shaped contact piece" is respectively disposed in contact with all inner walls of the second end of the through slot 111; the contact portion 16 may also be a contact point, disposed on the upper inner wall or the lower inner wall of the second end of the through slot 111 in the vertical direction, which is not specifically limited here.

[0051] The warning part 17 may include a warning part body 171, a warning unit 172 and a loop spring part 173. The first end of the warning part body 171 is arranged in the through groove 111, and the second end of the warning part body 171 is suspended in the through groove 111 and is provided with the loop spring part 173. The warning unit 172 is arranged at the first end of the measuring part 11. The warning unit 172 is used to send a warning signal when the measuring part 11 is deformed in the vertical direction and the loop spring part 173 contacts the contact part 16.

[0052] The first end of the warning portion body 171 may be disposed in the through slot 111 in the following manner, or in other manners, which are not specifically limited herein.

[0053] For example, refer to Figure 3 and Figure 4 As shown, Figure 3is a structural exploded diagram of an acupuncture pressure test module provided by an embodiment of the present application, Figure 4 yes Figure 3 The position-limiting portion 14 is provided with a clamping structure 141, and the clamping structure 141 clamps the main body 171 of the warning portion. Specifically, the position-limiting portion 14 can be an irregular cube, and the clamping structure 141 is located on the side where the second end of the position-limiting portion 14 is located. When the clamping structure 141 clamps the main body 171 of the warning portion, the main body 171 of the warning portion can float in the through groove 111. Figure 3 As shown, the clamping structure 141 can be a part of the second end of the limiting portion 14, and the limiting portion 14 can limit the deformation of the measuring portion 11 through the solid part of the second end; the clamping structure 141 can be the second end of the limiting portion 14, when the measuring portion 11 is deformed in the vertical direction exceeding the deformation limit of the strain sensor 15, the inner wall of the through groove 111 will contact the clamping structure 141, and at this time, the clamping structure 141 will prevent the measuring portion 11 from continuing to deform, so that the deformation of the measuring portion 11 can be limited, etc., and no specific limitation is made here.

[0054] For another example, the first end of the main body 171 of the warning part is arranged in parallel with the limiting part 14 at the first end of the through slot 111. Specifically, the entity part of the limiting part 14 is parallel to the main body 171 of the warning part, and they do not interfere with each other. When the measuring part 11 is deformed in the vertical direction exceeding the deformation limit of the strain sensor 15, the contact part 16 located on the inner wall of the through slot 111 will contact the circuit spring part 173 on the main body 171 of the warning part, so that the warning unit 172 can send a warning signal. At the same time, the second end of the limiting part 14 touches the inner wall of the through slot 111, thereby limiting the further deformation of the measuring part 11.

[0055] In addition, the main body 171 of the warning part can be a hollow body, and the circuit connecting the loop spring part 173 and the warning unit 172 can be arranged inside the main body 171 of the warning part, which can reduce the exposure of the external circuit or line of the warning part 17, thereby reducing the influence of the exposed circuit of the warning part 17 on the needle pressure measurement; the main body 171 of the warning part can be a solid body, and the other parts of the circuit formed by the loop spring part 173 and the warning unit 172 can be external, etc., which are not specifically limited here. Among them, the specific circuit connecting the loop spring part 173 and the warning unit 172 is diverse, and can be Figures 5 to 8 The circuit diagram shown, Figures 5 to 8 The circuit shown in can be connected to an external controller so that data can be fed back to the external controller.

[0056] In addition, the warning unit 172 can be a sound alarm module such as a buzzer, and when the loop spring piece part 173 contacts the contact part 16, the sound alarm module sends out a sound warning signal; the warning unit 172 can also be a light alarm module such as an LED, and when the loop spring piece part 173 contacts the contact part 16, the light alarm module sends out a light warning signal; the warning unit 172 can also be a sound and light alarm module, and when the loop spring piece part 173 contacts the contact part 16, the sound and light alarm module sends out a sound and light warning signal. In addition, the setting of the warning unit 172 at the first end of the measuring part 11 can be achieved by attaching the warning unit 172 to the surface of the first end of the measuring part 11, or by embedding the warning unit 172 in the first end of the measuring part 11, for example, Figure 3 As shown, the first end of the measuring portion 11 is provided with an embedding portion 112 , and the warning unit 172 can be embedded in the embedding portion 112 .

[0057] In one embodiment, in order to meet specific usage scenarios, the connecting seat 12 is further provided with a base plate. When the measuring part 11 is installed on the connecting seat 12, the base plate supports the other parts of the measuring part 11 except the probe part 13. At this time, the measuring part 11 is blocked by the base plate and cannot be deformed downward. Therefore, the strain sensor 15 is only required to be provided on the upper surface of the measuring part 11 in the vertical direction. Similarly, the contact part 16 is required to be provided on the upper inner wall of the second end of the through groove 111, so that the deformation of the measuring part 11 in the upward direction in the vertical direction can be limited and warned.

[0058] In one embodiment, a plurality of contact portions 16 are provided, at least one of the plurality of contact portions 16 is provided on the upper inner wall of the second end of the through slot 111 in the vertical direction, and at least one of the plurality of contact portions 16 is provided on the lower inner wall of the second end of the through slot 111 in the vertical direction.

[0059] Reference Figure 3 and Fig. 9 As shown, in Figure 3 and Fig. 9In the illustrated embodiment, two contact portions 16 are provided, one of the two contact portions 16 is provided on the upper inner wall of the second end of the through slot 111 in the vertical direction, and the other is provided on the lower inner wall of the second end of the through slot 111 in the vertical direction. When the measuring portion 11 undergoes an upward deformation in the vertical direction exceeding the deformation limit of the strain sensor 15, the circuit spring portion 173 contacts the contact portion 16 provided on the upper inner wall of the second end of the through slot 111 in the vertical direction, so that the circuit of the warning unit 172 is turned on and a warning signal is issued. Similarly, when the measuring portion 11 undergoes a downward deformation in the vertical direction exceeding the deformation limit of the strain sensor 15, the circuit spring portion 173 contacts the contact portion 16 provided on the lower inner wall of the second end of the through slot 111 in the vertical direction, so that the circuit of the warning unit 172 is turned on and a warning signal is issued. Similarly, when the measuring portion 11 undergoes a downward deformation in the vertical direction exceeding the deformation limit of the strain sensor 15, the circuit spring portion 173 contacts the contact portion 16 provided on the lower inner wall of the second end of the through slot 111 in the vertical direction, so that the circuit of the warning unit 172 is turned on and a warning signal is issued.

[0060] In one embodiment, the loop spring sheet portion 173 may include two groups of loop spring sheets 174, each group of loop spring sheets 174 is disposed at the second end of the warning portion body 171, one pair of the two groups of loop spring sheets 174 corresponds to the contact portion 16 disposed on the upper inner wall of the second end of the through slot 111 in the vertical direction, and the other pair corresponds to the contact portion 16 disposed on the lower inner wall of the second end of the through slot 111 in the vertical direction. Figure 3 As shown, at least two loop springs 174 are included, and the specific number can be two, three, four, etc., to ensure that a loop can be formed during the contact process with the contact portion 16. In addition, for the multiple loop springs 174 in each group of loop springs 174, the parts of the multiple loop springs 174 that contact the contact portion 16 can be flush with each other, or there can be a height difference, which is not specifically limited here.

[0061] For example, the warning unit 172 includes a plurality of LEDs, and a pair of loop springs 174 corresponding to the contact portion 16 disposed on the upper inner wall of the second end of the through slot 111 in the vertical direction includes three loop springs 174, the height of the first loop spring 174 is relatively the highest, the third loop spring 174 is relatively the lowest, and the height of the second loop spring 174 is between the height of the first loop spring 174 and the height of the third loop spring 174. When the measuring part 11 deforms downward in the vertical direction exceeding the deformation limit of the strain sensor 15, the contact portion 16 on the upper inner wall of the second end of the through slot 111 in the vertical direction will first contact the first loop spring 174 and will not contact the second loop spring 174, and a path for the LED cannot be formed, and at this time, no LED in the warning unit 172 emits light. At this time, when the measuring part 11 continues to deform downward, the first loop spring 174 will also be pressed down by the upper inner wall of the second end of the through slot 111 in the vertical direction. When the measuring part 11 continues to deform downward until the contact part 16 contacts the first loop shrapnel 174 and the second loop shrapnel 174 at the same time, an LED passage will be formed, and at this time one or more LEDs in the warning unit 172 will emit light, forming a light warning signal of the first color. At this time, when the measuring part 11 continues to deform downward, the first loop shrapnel 174 and the second loop shrapnel 174 will also be pressed down by the second end of the through groove 111 in the vertical direction. The upper inner wall, when the measuring part 11 continues to deform downward until the contact part 16 contacts the three loop shrapnel 174 at the same time, two parallel LED passages are formed, and at this time, multiple LEDs in the warning unit 172 emit light, forming a light warning signal of the second color. By arranging multiple loop shrapnel 174 of different heights in a pair of loop shrapnel 174, the warning unit 172 can send different warning signals according to the different deformation degrees of the measuring part 11, so that the technician can determine the specific deformation degree of the strain sensor according to the light warning signals of different colors, thereby improving the convenience of use.

[0062] In one embodiment, a plurality of strain sensors 15 are provided, at least one of the plurality of strain sensors 15 is provided on the upper surface of the measuring portion 11 in the vertical direction, and at least one of the plurality of strain sensors 15 is provided on the lower surface of the measuring portion 11 in the vertical direction. For example, there may be one, two, etc. strain sensors 15 provided on the upper surface of the measuring portion 11 in the vertical direction, and there may be one, two, etc. strain sensors 15 provided on the lower surface of the measuring portion 11 in the vertical direction, which are not specifically limited here.

[0063] Reference Fig.10 As shown, Fig.10The circuit corresponding to the warning unit 17 is shown. In one embodiment, the strain sensor 15 and the warning unit 172 are both connected to the control unit 2, so that when the data fed back by the strain sensor 15 indicates that the deformation of the measuring part 11 reaches the preset deformation degree, the control unit 2 causes the warning unit 172 to send out a warning signal. When the needle pressure test module 1 needs to be used, it needs to be connected to a certain device through the connecting seat 12. Under this premise, the control unit 2 can be a control unit inside the device, and the strain sensor 15 and the warning unit 172 are electrically connected through the additional I / O port of the control unit 2, and the warning unit 172 is controlled by the control unit 2; the control unit 2 can also be an independent supporting control unit 2, that is, the needle pressure test module 1 is provided with a control unit that is not inside the device, and the strain sensor 15 and the warning unit 172 are electrically connected through the additional I / O port of the control unit 2, and the warning unit 172 is controlled by the control unit 2, etc., which is not specifically limited here. In addition, the control unit 2 may be a unit constructed based on a microcontroller (MCU) such as a single chip microcomputer, a high-performance RISC machine (Advanced Reduced Input Set Computing Machines, ARM), etc., which is not specifically limited here.

[0064] Specifically, when the strain sensor 15 deforms following the measurement part 11, it will feedback data to the control unit 2, and the control unit 2 can perform pressure calculation based on the feedback data and determine the specific force currently applied to the measurement part 11. Within the deformation capacity range of the strain sensor 15, since the deformation degree of the strain sensor 15 is positively correlated with the specific force applied to the measurement part 11, the specific deformation degree of the strain sensor 15 can be determined based on the specific force applied to the measurement part 11. Based on this, a force threshold can be set to represent the extreme deformation degree of the strain sensor 15. When the specific force applied to the measurement part 11 is equal to the force threshold, at this time, the deformation of the measurement part 11 reaches the preset deformation degree, and the deformation of the strain sensor 15 reaches the extreme deformation degree, and the control unit 2 will control the warning unit 172 to send a warning signal.

[0065] In one embodiment, the material of the measuring part 11 is a metal material, and each surface of the measuring part 11 may be coated with an insulating coating, and the strain sensor 15 may be attached to the insulating coating. When the insulating package of the strain sensor 15 is damaged, since the measuring part 11 is coated with the insulating coating, the strain sensor 15 cannot conduct electricity to other components (such as the warning part 17) and other structures through the measuring part 11, thereby reducing the impact of the damage of the insulating package of the strain sensor 15 on the operation of the needle pressure test module 1.

[0066] In one embodiment, the material of the measuring part 11 is an insulating material, and the probe part 13 may include a clamping block, and the clamping block may clamp the acupressure probe. Among them, the clamping block may be a metal material. Since the measuring part 11 is made of insulating material, the insulation capacity between the strain sensor 15 and the probe part 13 can be improved, so that when the insulating package of the strain sensor 15 is damaged, the strain sensor 15 cannot conduct electricity to the probe part 13 through the measuring part 11, thereby reducing the situation of energizing the test unit and causing damage to the test unit due to damage to the insulating package of the strain sensor 15, and avoiding the influence of accidental conduction of the probe part 13 on the normal operation of the strain sensor 15.

[0067] In one embodiment, the probe part 13 may include an acupressure probe 131, a clamping block 132 and an insulating block 133. The clamping block 132 may be used to clamp the acupressure probe 131, and the insulating block 133 is installed at the second end of the measuring part 11. The insulating block 133 may be used to insulate the mounting of the clamping block 132. The clamping block 132 may be made of a metal material, an insulating material, or a metal material coated with an insulating coating, etc., which is not specifically limited here. By providing the insulating block, the clamping block 132 can be insulated and installed in the measuring part 11, thereby improving the installation convenience of the probe part 13, and improving the insulation capacity between the probe part 13 and the strain sensor 15 during installation and normal operation, thereby reducing mutual interference between the two.
