Description

Technical Field

[0001] The utility model relates to the technical field of testing, in particular to a testing device and a testing system. Background Art

[0002] LCC (Leadless Chip Carriers) uses SMD packaging, with pins bent inward at the edge of the chip, close to the chip, which can reduce the installation volume. LGA (Land Grid Array) replaces the traditional pin pins with metal contact packaging.

[0003] When the module under test adopts packaging technology such as LCC and LGA, elastic pins are usually used to electrically connect the pins on the test board to lead out the test points during signal testing. In order to improve the signal transmission rate, control the impedance of the wiring and improve the signal anti-interference ability, the existing test board generally sets the wiring inside the test board, making it difficult to lead out the test points on the test board. Even if the test points are led out, the impedance of the elastic pins is usually large, which will affect the signal quality of the module under test. With the improvement of the integration of electronic equipment, the number of pins on the module under test has increased significantly, and the density is large. If the test point is led out at each signal pin on the test board, the elastic pin will top the pin of the module under test, seriously affecting the test results. In addition, the pin density of the module under test is large, and the elastic pins are also required to reduce the spacing, which is easy to cause the slot to break and thus cause the risk of short circuit. Moreover, the slot is also prone to damage after multiple modules under test are repeatedly inserted and pulled out. In addition, the existing test fixture is usually a manual fixture, which requires manual pressing of the module under test and the test board to ensure that the two are tightly electrically connected. Current testing methods are highly dependent on manual labor. If the manual operation is unskilled, inaccurate test results may occur easily. Even if the test is performed by skilled personnel, fatigue and other reasons may lead to inconsistent test conditions, resulting in inaccurate test results. Utility Model Content

[0024] In order to make the purpose, technical scheme and advantages of the utility model clearer, the various embodiments of the utility model will be described in detail below with reference to the accompanying drawings. However, it can be understood by those skilled in the art that in the various embodiments of the utility model, many technical details are provided in order to enable readers to better understand the present application.

[0026] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0027] In addition, the terms "installed", "set", "provided with", "opened", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0028] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0029] The existing test solutions for LCC and LGA modules to be tested have problems such as complex test processes, low accuracy, and poor consistency due to the complex structure, low stability, and high manual dependence of the test devices used. In addition, the slots are very easy to be damaged after repeated use, and different specifications and types of modules to be tested need to use different slots, which greatly increases the test cost.

[0030] In order to solve the above technical problems, the first aspect of the utility model provides a test device, including: a test bench; a test fixture, detachably arranged on the test bench, the test fixture including a test board and a conductive glue, the test board is located below the conductive glue and electrically connected to the conductive glue, the conductive glue is used to carry the module to be tested and electrically connected to the module to be tested, so that the test board is electrically connected to the module to be tested; a cover assembly, arranged on the test bench and movable relative to the test bench; a drive assembly, connected to the cover assembly; during testing, the drive assembly is used to drive the cover assembly to press down the module to be tested so that the module to be tested is electrically connected to the conductive glue. The second aspect of the utility model provides a test system, including: a host computer and the above test device, the host computer is electrically connected to the test device, and is used to send control instructions to the drive assembly of the test device.

[0031] The test device of the embodiment of the utility model uses conductive glue to replace the existing slots and elastic pins to electrically connect the module to be tested and the test board, which simplifies the structure of the test device. During the test, the driving component drives the cover plate component to press down the module to be tested, so that the module to be tested is electrically connected to the test board through the conductive glue. The driving component is used to press down the module to be tested to replace the existing manual operation, which can simplify the operation process of the operator and reduce the manual dependence of the test process. The mechanical automatic pressing can better ensure the consistency of different modules to be tested during testing, so as to improve the accuracy of the test results.

[0032] The implementation details of the test device and the test system of this embodiment are described in detail below. The following content is only provided for easy understanding of the implementation details and is not necessary for implementing this solution.

[0033] See also Figure 1 and Figure 2 The test device 100 of this embodiment includes: a test bench 101, a test fixture 102, a cover assembly 103 and a drive assembly 104. The test fixture 102 is detachably arranged on the test bench 101, and the test fixture 102 includes a test board 1021 and a conductive adhesive 1022. The test board 1021 is located below the conductive adhesive 1022 and is electrically connected to the conductive adhesive 1022. The conductive adhesive 1022 is used to carry a module to be tested (not shown in the figure) and is electrically connected to the module to be tested, so that the test board 1021 is electrically connected to the module to be tested. The cover assembly 103 is arranged on the test bench 101 and is movable relative to the test bench 101. The drive assembly 104 is connected to the cover assembly 103. During testing, the drive assembly 104 is used to drive the cover assembly 103 to press down the module to be tested so that the module to be tested is electrically connected to the conductive adhesive 1022.

[0034] By using the conductive adhesive 1022 to replace the existing slots and elastic pins, so that the module to be tested and the test board 1021 are electrically connected, the structure of the test device 100 is simplified, and the operation process of the operator can be simplified. During the test, the cover assembly 103 is driven by the driving assembly 104 to press down the module to be tested, so that the module to be tested is electrically connected to the test board 1021 through the conductive adhesive 1022. The automatic operation of the driving assembly 104 replaces the manual operation, which can simplify the operation process of the operator and reduce the manual dependence of the test process. At the same time, the automatic pressing can better ensure the consistency of the tests of different modules to be tested, so as to improve the accuracy of the test results.

[0035] It should be noted that the manufacturing cost of the conductive adhesive is low, and it can be flexibly cut according to actual needs to obtain a suitable shape and size. That is, different conductive adhesives 1022 can be manufactured for modules under test of different shapes, specifications and types to meet different test requirements. In addition, the use of conductive adhesive for connection has high electrical and radio frequency connection stability and no physical deviation. The friction of the conductive adhesive 1022 itself can also prevent the module under test from shifting.

[0036] The conductive adhesive 1022 includes an adhesive block and metal particles, the metal particles are embedded in the adhesive block, and the module to be tested and the test board 1021 are electrically connected through the metal particles. It can be understood that the conductive adhesive 1022 is molded or cut according to the module to be tested to form a suitable conductive adhesive 1022.

[0037] In some embodiments, the test fixture 102 further includes a download plate 1023 and an upper upload plate 1024 arranged in parallel, and the test board 1021 is fixed to the download plate 1023 and is located between the download plate 1023 and the upper upload plate 1024. The upper upload plate 1024 has a mounting opening 1024a for exposing the test board 1021, and the conductive adhesive 1022 is disposed in the mounting opening 1024a.

[0038] The download board 1023 and the upper loading board 1024 can be connected by screws or bolts, and the test board 1021 can be clamped and fixed between the download board 1023 and the upper loading board 1024. Alternatively, the test board 1021 can be fixed to the download board 1023 by screws or bolts. Alternatively, the test board 1021 can be fixed to the download board 1023 by using structures such as buckles and clamps. In this way, when the type and specification of the test board 1021 need to be adjusted due to testing different modules to be tested, the test board 1021 can be disassembled and replaced with the required test board.

[0039] There is no specific limitation on the sizes of the download board 1023 and the upper upload board 1024, as long as they can be stably placed on the test bench 101. The download board 1023 can be larger than the upper upload board 1024, or smaller than the upper upload board 1024, or have the same size as the upper upload board 1024. In this embodiment, the example that the size of the download board 1023 is smaller than that of the upper upload board 1024 is used for description.

[0040] The test fixture 102 can be detachably mounted on the test bench 101 in a variety of different installation methods. For example, a groove can be set on the test bench 101, and the groove has a non-circular contour. The upper loading plate 1024 has an outer contour that matches or is close to the groove. When the test fixture 102 is placed in the groove, the upper loading plate 1024 is relatively fixed relative to the test bench 101 and will not shift or shake. When it is necessary to change the test fixture 102 according to the test requirements of other modules to be tested, the test fixture 102 can be directly removed and replaced with other test fixtures.

[0041] Alternatively, a plurality of positioning pins (not shown in the figure) may be provided on the test bench 101, and a plurality of positioning holes or positioning grooves may be correspondingly provided on the download plate 1023 and the upload plate 1024. When installing the test fixture 102, the positioning holes or positioning grooves on the download plate 1023 and the upload plate 1024 correspond to the positioning pins, and the positioning pins are extended into the positioning holes or positioning grooves for positioning installation.

[0042] Alternatively, a locking buckle (not shown in the figure) can be provided on the test bench 101. When the test fixture 102 is placed on the test bench 101, the test fixture 102 is fixed by pressing the locking buckle, or the locking buckle is fixed by cooperating with the matching structure on the test fixture 102, thereby fixing the test fixture 102.

[0043] Alternatively, the test bench 101 may be provided with fixing holes (not shown in the figure), and the upper loading plate 1024, or the unloading plate 1023 and the upper loading plate 1024, may also be provided with corresponding fixing holes, and the test fixture 102 may be fixed to the test bench 101 through the fixing holes by means of screws, bolts, rivets and other fasteners.

[0044] In the above various configurations, the upper surface of the upper loading plate 1024 can be configured to be flush with the upper surface of the test bench 101 , which can reduce the volume of the test device 100 and make the appearance of the test device 100 more beautiful.

[0045] It is understood that the profile of the mounting opening 1024a is preferably non-circular, for example, it can be square, oval, etc., to ensure that the conductive adhesive 1022 can maintain a stable position in the mounting opening 1024a, thereby ensuring the accuracy of the test results. In addition, the size and outer profile of the conductive adhesive 1022 can be set to match the mounting opening 1024a, further stabilizing the position of the conductive adhesive 1022.

[0046] The edge of the mounting opening 1024a formed by the upper loading plate 1024 is chamfered. With such a configuration, when the operator puts the conductive adhesive 1022 into the mounting opening 1024a, the chamfer of the edge of the mounting opening 1024a can guide the conductive adhesive 1022 to accurately enter the mounting opening 1024a to a certain extent, thereby reducing the difficulty of placing the conductive adhesive 1022.

[0047] Optionally, the chamfer can be set as a cut angle or an arc angle. Preferably, the chamfer is set as a round chamfer, and the round chamfer surface is smooth, which can avoid scratching the conductive adhesive 1022.

[0048] See also Figures 3 to 5 In some embodiments, the cover plate assembly 103 includes a pressure head cover plate 1031, a pressure head mounting plate 1032 and a pressure head 1033, wherein the pressure head mounting plate 1032 is detachably fixed to the pressure head cover plate 1031 and is located above the test fixture 102, and the pressure head 1033 is detachably arranged on a side of the pressure head mounting plate 1032 facing the test fixture 102 and is located above the test fixture 102.

[0049] The pressure head cover plate 1031 has a through hole 1031a. During testing, the module to be tested is placed on the conductive adhesive 1022. The pressure head 1033 passes through the through hole 1031a and extends into the mounting opening 1024a through the through hole 1031a to press down the module to be tested, thereby electrically connecting the module to be tested to the test board 1021 through the conductive adhesive 1022.

[0050] It can be understood that when the size of the pressure head 1033 is the same as or close to the size of the installation opening 1024a, the outer contour of the pressure head 1033 is the same as or close to the contour of the installation opening 1024a. When the size of the pressure head 1033 is smaller than the size of the installation opening 1024a, the outer contour of the pressure head 1033 can be set arbitrarily according to actual needs, as long as the pressure head 1033 can be inserted into the installation opening 1024a.

[0051] The pressure head mounting plate 1032 can be detachably fixed to the pressure head cover plate 1031 by means of screws, bolts, clips or mortise and tenon joints. When the type of the module to be tested is changed, the test board 1021 and the upper loading plate 1024 may need to be replaced. At this time, if the upper loading plate 1024 is replaced, the pressure head 1033 also needs to be replaced accordingly. The pressure head mounting plate 1032 installed with other types of pressure heads can be directly replaced, thereby simplifying the operation steps.

[0052] The pressure head 1033 can also be fixed on the pressure head mounting plate 1032 with reference to the above-mentioned multiple detachable connection methods. Therefore, when replacing the module to be tested, if necessary, the pressure head 1033 can also be replaced to meet the pressing needs of different types of modules to be tested.

[0053] See again Figure 5 The cover plate assembly 103 also includes an elastic member 1034, and the elastic member 1034 is located between the pressure head mounting plate 1032 and the pressure head 1033. The pressure head 1033 is elastically connected to the pressure head mounting plate 1032 via the elastic member 1034. In this way, when the pressure head 1033 is pressed down to press the module to be tested and the conductive adhesive 1022, the elastic member 1034 can play a buffering role to avoid damage to the module to be tested during the pressing process.

[0054] The elastic member 1034 can be a spring, a rubber pad, a silicone pad or other elastic member or material, as long as it can play a buffering role. When the elastic member 1034 is a spring, if the size of the spring is large enough, only one can be provided, and if the size of the spring is small, multiple can be provided.

[0055] In some other embodiments, the pressure head 1033 may be made of an elastic material, such as rubber, plastic, etc., which is not specifically limited here.

[0056] See also Figure 5 and Figure 6 In some embodiments, the driving assembly 104 includes an upper and lower driving member 1041 and a connecting structure 1042, the upper and lower driving member 1041 is connected to the connecting structure 1042, the connecting structure 1042 is fixedly connected to the cover assembly 103, and the upper and lower driving member 1041 drives the connecting structure 1042 to drive the cover assembly 103 to move up and down.

[0057] The pressure head cover plate 1031 may be fixedly connected to the connection structure 1042 , and the up and down driving member 1041 drives the connection structure 1042 to move up and down to drive the pressure head cover plate 1031 to move up and down, thereby causing the pressure head 1033 to move up and down.

[0058] The upper and lower driving members 1041 can be cylinders or motors. When using cylinders, the beat can be preset according to the actual production situation, and production and testing can be carried out according to the preset beat, which is easy to operate and has a low manufacturing cost. Using motors can better control the downward stroke and thus the downward pressure.

[0059] Taking the upper and lower driving members 1041 as a cylinder for illustration, the connecting structure 1042 may include two parts, one is a fixed plate 1042a, which is fixedly connected to the piston of the cylinder; the other is a connecting plate 1042b, one end of which is fixedly connected to the fixed plate 1042a, and the other end extends vertically downward for a certain distance and is fixedly connected to the pressure head cover plate 1031.

[0060] Upper and lower guide rails 1011 may also be provided on the test bench 101, and a slider 1042c may be provided on the connecting plate 1042b, and the slider 1042c may be slidably provided on the upper and lower guide rails 1011. Thus, when the upper and lower driving members 1041 drive the connecting plate 1042b to move up and down, the upper and lower guide rails 1011 support the connecting plate 1042b through the slider 1042c, thereby avoiding the overall center of gravity shift of the connecting plate 1042b and the cover plate assembly 103, and improving the stability of the movement of the connecting plate 1042b and the cover plate assembly 103.

[0061] See again Figure 1In some embodiments, the driving assembly 104 further includes a front-rear driving member 1043, a slide rail 1044 and a slide plate 1045. The front-rear driving member 1043 is disposed on the test bench 101 and is spaced apart from the test fixture 102. The front-rear driving member 1043 is connected to the slide plate 1045. The slide plate 1045 is slidably disposed on the slide rail 1044. The up-down driving member 1041 is fixed to the slide plate 1045. The front-rear driving member 1043 is used to drive the slide plate 1045 to drive the up-down driving member 1041 to move forward and backward. That is, the up-down driving member 1041 is fixed on the slide plate 1045, and the front-back driving member 1043 can move the pressing head 1033 from the upper side of the installation opening 1024a to the top of the installation opening 1024a, or move the pressing head 1033 from the top of the installation opening 1024a to the upper side of the installation opening 1024a. In this way, during the test, the pressing head 1033 can be moved from the top of the installation opening 1024a to the upper side, so as to avoid the cover plate assembly 103 from blocking the installation opening 1024a, so as to facilitate the operator to sequentially place the conductive adhesive 1022 and the module to be tested into the installation opening 1024a. After the placement is completed, the pressing head 1033 is moved to the top of the installation opening 1024a to prepare for the next step of pressing.

[0062] It can be understood that when the upper and lower driving members 1041 are fixed on the slide plate 1045 , the upper and lower guide rails 1011 are also arranged on the slide plate 1045 .

[0063] The front and rear driving members 1043 can be cylinders or motors. When a cylinder is used, the beat can be preset according to the actual production situation, and production and testing can be carried out according to the preset beat, which is convenient for operation and has a low manufacturing cost. The use of a motor can better control the stroke of the downward pressure, and then control the downward pressure. When either of the upper and lower driving members 1041 and the front and rear driving members 1043 is a cylinder, the other is preferably set to a cylinder. In this way, the beats of the two driving members can be matched through a preset control program, thereby making the entire production process smoother.

[0064] See again Figure 5 The testing device 100 may further include a position sensor 1012 disposed on the testing platform 101 , and the position sensor 1012 is used to detect the position of the slide plate 1045 or the cover assembly 103 , so as to determine whether the cover assembly 103 is located directly above the testing fixture 102 .

[0065] Alternatively, the position sensor 1012 may be disposed at any position of the testing device 100 , and the probe of the position sensor 1012 may be disposed on the testing platform 101 .

[0066] The position sensor 1012 may be one or more of different types of sensors such as an optical sensor, a resistance sensor or a pressure sensor. In the present invention, the position sensor is an optical sensor, especially a fiber optic sensor, for example.

[0067] The optical fiber sensor is arranged on the test bench 101 and emits light in a specific direction. When the slide plate 1045 or the cover assembly 103 moves to a specific position, the slide plate 1045 or the cover assembly 103 blocks and reflects the light emitted by the optical fiber sensor, thereby triggering in-position information, indicating that the cover assembly 103 has reached the preset position, that is, the pressure head 1033 has reached directly above the installation port 1024a.

[0068] To further improve the accuracy of position detection, a reflective element of a specific size can be set on the side of the slide plate 1045 or the cover assembly 103 facing the optical fiber sensor, and a threshold of the reflected signal received by the optical fiber sensor can be set. In this way, the accuracy of position detection can be improved only when the light reflected by the reflective element can send out the position information.

[0069] Alternatively, the optical fiber sensor is disposed on the test bench 101 and emits light in a specific direction, and the slide plate 1045 or the cover assembly 103 continuously blocks the light emitted by the optical fiber sensor. When the slide plate 1045 or the cover assembly 103 moves to a specific position, the slide plate 1045 or the cover assembly 103 no longer blocks the light emitted by the optical fiber sensor, and the optical fiber sensor cannot receive the reflected light signal, thereby triggering the arrival information, indicating that the cover assembly 103 has reached the preset position, that is, the pressure head 1033 has reached directly above the installation port 1024a.

[0070] It can be understood that the position sensor 1012 can also use a camera, especially a CCD camera.

[0071] In order to further improve the accuracy of position detection, the position sensor 1012 may be configured to directly detect whether the position of the pressure head 1033 reaches directly above the installation opening 1024a.
