Description

Technical Field

[0001] The present application relates to the field of electrostatic testing, and in particular to a testing device and a testing method for testing a device to be tested. Background Art

[0002] During the testing process of electronic equipment, electrostatic testing is very important for electronic equipment. When users use electronic equipment, the charges carried by the users will enter the electronic equipment, which can easily cause damage to metal components or printed circuit boards inside the electronic equipment.

[0003] When using a traditional electrostatic test bench for testing, the electronic device being tested is placed directly on the test bench and static electricity is injected into the device. However, during this test, the discharge point of the electronic device is random. In other words, the static charge that enters the electronic device may flow out through any gap in the electronic device.

[0004] During the above test process, since the electrostatic charge in the electronic device will flow out from any gap in the electronic device, it is impossible to accurately simulate the path of the user discharging through the electronic device to other low-potential devices, which can easily lead to inaccurate test results.

[0050] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0051] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present application.

[0052] Currently, electronic devices are usually equipped with electronic components such as electronic circuit boards. These components are easily damaged by static electricity, resulting in lower performance. Therefore, static electricity testing of electronic devices has become particularly important.

[0053] In related technologies, when performing electrostatic testing on electronic devices, the device is typically placed directly on an electrostatic test device. After injecting electrostatic charge into the device multiple times, the device's functionality is tested to determine whether the device's electrostatic tolerance meets requirements. However, in this technical process, when electrostatic charge is injected into the electronic device, the direction of the charge flow within the device is not fixed.

[0054] For example, Figure 1 This is a schematic diagram of an electrostatic testing device provided in this application. Figure 1 As shown in the figure, it includes: a wooden table 10, a metal plate 11, an insulating plate 12 and an impedance element 13 composed of two 470 kilo-ohm resistors connected in series, wherein the metal plate 11 is placed on the wooden table 10, the insulating plate 12 is placed above the metal plate 11, and the metal plate 11 is connected in series with the impedance element 13 and then grounded. Figure 1 When testing electronic device 14 using the electrostatic testing equipment shown, electronic device 14 can be placed above insulating plate 12 while static electricity is injected into electronic device 14 using an electrostatic gun. When electronic device 14 receives the electrostatic charge from the electrostatic gun, the charge is emitted through any gaps within electronic device 14. This means that the direction of the charge flow within electronic device 14 is not fixed. The electrostatic charge emitted from electronic device 14 then passes through insulating plate 12 below electronic device 14, transmitting to metal plate 11 below insulating plate 12, and ultimately to impedance element 13 connected to metal plate 11.

[0055] However, in an actual application scenario, when a user touches and uses an electronic device, the electrostatic charge carried by the user will be transferred to the electronic device due to the contact between the user and the electronic device, and when the user holds the electronic device and touches other low-potential objects, the electrostatic charge carried by the user will flow to the electronic device, and the static electricity flowing into the electronic device will be transmitted to the other low-potential objects through the contact points between the electronic device and the other low-potential objects. In other words, the inside of the electronic device will undergo two discharge processes at this time, namely the discharge of the user to the inside of the electronic device, and the discharge of the inside of the electronic device to the other low-potential objects. Moreover, the two discharge processes of the above-mentioned electronic device usually cause the electronic components inside the electronic device to be damaged due to electrostatic charge.

[0056] In related technologies, when performing electrostatic testing on electronic devices, the electrostatic charge injected into the electronic device may be released from any gap in the electronic device due to the non-fixed discharge path, and thus cannot accurately simulate the electrostatic discharge process suffered by the electronic device in the above-mentioned actual usage scenario, which can easily lead to inaccurate final electrostatic test results.

[0057] The test equipment and test method provided in this application for testing the device to be tested are used to solve the above-mentioned technical problems.

[0058] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0059] Figure 2 This is a schematic diagram of the structure of a test device for testing a device to be tested provided in an embodiment of the present application. Figure 2 As shown, the test equipment includes an electrostatic device (not shown in the figure), an insulation test table 20, a conductive medium 21, and a first impedance element 22; the device to be tested 23 and the conductive medium 21 are placed on the insulation test table 20, and the device to be tested 23 is in contact with the conductive medium 21; the conductive medium 21 is electrically connected to the first impedance element 22, and the first impedance element 22 is grounded; the electrostatic device is used to emit static electricity to the device to be tested 23; the conductive medium 21 is used to transmit the charge transmitted after the device to be tested 23 contacts the static electricity to the first impedance element 22.

[0060] Illustratively, the test equipment provided in this embodiment includes: an electrostatic device, an insulation test bench 20 , a conductive medium 21 , and a first impedance element 22 .

[0061] Furthermore, to simulate the secondary discharge scenario of a user during actual use of the device under test 23, in this embodiment, the test device is provided with a conductive medium 21, which is in contact with the device under test 23. Furthermore, the conductive medium 21 is electrically connected to a first impedance element 22, and the first impedance element 22 is grounded. The first impedance element 22 can be used to simulate the impedance of a user of the electronic device. Furthermore, by having the device under test 23 in contact with the conductive medium 21 and the conductive medium 21 being grounded via the first impedance element 22, a scenario in which a user standing on the ground and using the device under test 23 can be simulated.

[0062] When the test device of this embodiment is in use, the device under test 23 and the conductive medium 21 in contact with the device under test 23 can be placed on the insulation test bench 20, and the conductive medium 21 is also grounded via the first impedance element 22. Thereafter, an electrostatic generator can be turned on to inject electrostatic charge into the device under test 23. Because the device under test 23 is in contact with the conductive medium 21, the charge injected into the device under test 23 by the electrostatic generator is conducted to the conductive medium 21, and then conducted through the conductive medium 21 to the first impedance element 22 electrically connected to the conductive medium 21, and then transmitted to the ground through the grounding point of the first impedance element 22.

[0063] In this embodiment, by setting a first impedance element 22 and a conductive medium 21 in the test device, and making the conductive medium 21 contact with the test device, the user's contact with the device to be tested 23 is simulated. In addition, the conductive medium 21 is electrically connected to the first impedance element 22, and the first impedance element 22 is grounded, thereby simulating the real scene when the user uses the device to be tested 23. When the electrostatic device emits static electricity to the device to be tested 23, at this time, the electrostatic transmission path of the static electricity in the device to be tested 23 is similar to the electrostatic transmission path when the operator actually uses the device to be tested 23, thereby improving the accuracy of the test of the device to be tested 23. Compared with the related art, when the device to be tested 23 is tested, the electrostatic charge is transmitted along a random path in the device to be tested 23. The electrostatic transmission path in this embodiment can be used to simulate the real electrostatic transmission path of the device to be tested 23 during use, thereby improving the accuracy of the electrostatic test results.

[0064] In some embodiments, the conductive medium 21 contacts a first region of the device under test 23 , wherein the first region is a region on the device under test 23 that is used to contact a human body.

[0065] For example, in order to simulate the static electricity phenomenon generated by the human body when using the device to be tested 23 in an actual application scenario, in this embodiment, when setting the conductive medium 21, the conductive medium 21 can be in contact with the area on the device to be tested 23 that contacts the human body. In addition, the device to be tested 23 in this embodiment can be a handheld device, such as a mobile phone, a bracelet, a remote control and other electronic devices. When the handheld device is tested using the above-mentioned test equipment, the conductive medium 21 can be in contact with the place on the handheld device where the human body often contacts the handheld device, and then the conductive medium 21 is used to simulate the contact between the human hand and the handheld device. During the electrostatic test process, the direction of the static electricity in the handheld device is closer to the static electricity direction when the human body injects static electricity into the handheld device during the actual application of the handheld device, so that the results of subsequent electrostatic tests are more accurate.

[0066] In some embodiments, the conductive medium 21 may be a metal sheet. When the conductive medium 21 is a metal sheet, the metal sheet may be placed on the surface of the device under test 23 in contact with the human body to simulate a human hand.

[0067] For example, the device to be tested 23 is taken as a remote controller for description. Figure 3 This is a schematic diagram of a configuration of a conductive medium provided in an embodiment of the present application. Figure 3 As shown, Figure 3 Figure (a) is a top view of the remote control. When the conductive medium is a metal sheet 31, the metal sheet 31 can cover the gap between the buttons 32 of the remote control. Figure 3 Figure (b) is a left view of the remote control, and the dotted line in the figure represents the gap in the shell of the remote control, and the gap in Figure (b) is also covered with a metal sheet 31. Figure 3 Figure (c) in the figure is a front view of the remote control. In Figure (c), the dotted line in the figure is used to represent the gap in the surface shell of the remote control, and a metal sheet 31 is also provided on the surface shown in the figure. When providing the metal sheet 31, it can be considered to stick the metal sheet 31 on various surfaces of the remote control, or a fixing component can be used to fix the metal sheet 31 on various surfaces of the remote control. For example, the fixing component can be a cable tie, and the metal sheet 31 is then tied and fixed to the surface of the remote control. In addition, the metal sheets 31 on the remote control are all electrically connected to the first impedance element 12, and the other end of the first impedance element 12 is grounded. Furthermore, the metal sheet provided on the remote control can be used to simulate the use scenario of a person holding the remote control.

[0068] In some embodiments, the conductive medium 21 can be a flexible conductive medium such as a metal mesh, a metal film, or a metal foil (e.g., aluminum foil, copper foil, etc.). For example, when the conductive medium 21 is a metal mesh among flexible conductive media, during the use of the above-mentioned test device, the metal mesh can be placed in contact with the device to be tested 23, and the metal mesh can be placed in the device to be tested 23 where the human body often comes into contact with the device to be tested 23. In addition, the metal mesh can also be grounded through the first impedance element 22. Furthermore, when the device to be tested 23 and the metal mesh are placed on the insulation test bench 20, and the metal mesh is placed in an area on the device to be tested 23 that often comes into contact with the human body, and the metal mesh is also grounded through the first impedance element 22, at this time, static electricity is injected into the area of the device to be tested that is not in contact with the metal mesh through the electrostatic device. After the electrostatic charge enters the device to be tested 23, due to the contact between the device to be tested 23 and the metal mesh, the electrostatic charge is transmitted to the metal mesh, and then transmitted to the first impedance element 22 connected to the metal mesh, wherein the first impedance element 22 is used to simulate the impedance of the human body.

[0069] In this embodiment, compared with setting a metal sheet on the surface of the object to be tested, using a flexible conductive medium as the conductive medium 21 in the test device in contact with the human body can better simulate the real scene when a person holds the device to be tested 23 and improve the test accuracy.

[0070] In an actual application scenario, the device to be tested 23 is taken as a remote controller as an example for description. Figure 4 This application provides an electrostatic transmission path. Figure 4 As shown in the figure, when it is necessary to perform an electrostatic test on the remote control, the electrostatic test equipment in the related art is used for testing. At this time, it is only necessary to place the remote control on the electrostatic test platform and use the electrostatic gun to discharge the remote control. For example, when Figure 4 When static electricity is injected into the switch of the remote control shown, since there are many gaps on the remote control housing itself, after the static electricity is injected into the remote control, it is possible to be released from any gap of the remote control. Figure 4 As can be seen from the two arrows in the figure, static electricity is injected from the upper left side of the circular switch and then flows out from the right side of the circular switch.

[0071] When the test equipment provided by the embodiment of the present application is used for testing, the device to be tested 23 is taken as an example of a remote control for explanation. In the actual application scenario of the actual remote control, when the user uses the remote control, the static electricity problem that is actually encountered is that the user's body is charged first due to friction from clothing, or when the user stands up from the sofa or falls on the sofa, etc. When the user holds the remote control, the remote control starts to charge, that is, the charge generated on the user's body will be transmitted to the remote control, and then the remote control will carry static electricity with the same polarity and static electricity level as the static electricity generated on the user's body. When a person holds the remote control and touches other low potentials (for example, a metal coffee table, etc.), the human body discharges the low potential through the remote control, resulting in a large amount of charge in the human body being released through the remote control. Figure 5 This is a schematic diagram of another electrostatic transmission path provided in an embodiment of the present application. Figure 5 As shown, when static electricity is generated in the human body and the bottom of the remote control is held, the static electricity will be transferred into the remote control from the gap at the bottom. Figure 5 Inject into the gap pointed by the arrow on the bar button. Afterwards, if a person holds the remote control and touches the top of the remote control to other low-potential objects, the static charge transmitted by the human body in the remote control will be transmitted through the bottom of the remote control to the top of the remote control, and then from the place where the top of the remote control touches other low-potential objects to other low-potential objects, thereby causing the static charge carried by the human body to be continuously transmitted through the bottom and top of the remote control to other low-potential objects. For example, Figure 5 In the figure, the charge generated by the person is injected from the arrow on the bar button, along the dotted line, to the top of the remote control, and then flows out from the gap on the side of the top of the remote control. In this electrostatic transmission path, because the large amount of charge carried by the human body is continuously transmitted along this transmission path, as people use the remote control more and more, the electrostatic current generated during use can damage the electronic components in the remote control, thereby affecting the remote control's operating performance and reducing user satisfaction.

[0072] However, when the test equipment provided in the embodiment of the present application is used, the description will continue by taking the test equipment as an example of a remote control. When using the above-mentioned test equipment, the metal mesh can be brought into contact with the bottom of the remote control. Afterwards, during the electrostatic test, static electricity is emitted to the top of the remote control through the electrostatic device. Due to the contact between the bottom of the remote control and the metal mesh, and the conductive properties of the metal mesh, the static electricity received by the top of the remote control will be transmitted through the bottom of the remote control to the metal mesh in contact with the bottom of the remote control, and the first impedance element 22 connected to the metal mesh. It can be understood that during the test, the first impedance element 22 is a component for simulating human body impedance, and the metal mesh is used to simulate the scenario of a human hand holding an electrostatic device. The flow direction of the electrostatic charge in this embodiment is: electrostatic device, top of the remote control, bottom of the remote control, metal mesh, and first impedance element 22. The above Figure 3 The flow direction of electrostatic charge in the remote control is: human body, human hand, bottom of remote control, top of remote control, and other low-potential objects in contact with the top of remote control. Figure 3 The direction of electrostatic charge in the test and the direction of electrostatic charge when the test equipment is used can be seen. It can be seen that the two are the same in the electrostatic transmission path, so that when the electrostatic test is performed by the above-mentioned test equipment, the test results are more accurate and more reliable.

[0073] In addition, during the actual test process, the polarity of the electrostatic charge emitted by the electrostatic device can be continuously changed, thereby simulating the impact of the transmission of electrostatic charges of different polarities on the device under test 23 under the transmission path of the electrostatic charge.

[0074] In some embodiments, the flexible conductive medium contacts the first area of the device under test 23 by winding, or the flexible conductive medium contacts the first area of the device under test 23 by pasting.

[0075] For example, in this embodiment, when the conductive medium 21 is a metal mesh, when the metal mesh contacts the device under test 23 , the metal mesh may be wound around the first region of the device under test 23 in a winding manner.

[0076] For example, when the device to be tested 23 is a remote controller, it may be considered to wrap the metal mesh around the bottom of the remote controller. Figure 6 As shown, Figure 6 A schematic diagram of a metal mesh configuration method provided in an embodiment of the present application. Figure 6 In the figure, the shaded area in the remote control represents the area wrapped with metal mesh. Specifically, when wrapping the metal mesh, one or more layers of metal mesh can be wrapped around the first area of the device under test 23. When multiple layers of metal mesh are wrapped, the electrostatic charge in the device under test 23 can be transferred through the metal mesh.

[0077] In addition, the metal mesh in the test device can also be brought into contact with the device to be tested 23 by gluing. For example, when the device to be tested 23 is a wearable object such as a smart bracelet or a smart watch, since the user's body usually contacts the inner side of the smart bracelet or the inner side of the smart watch during the wearing process, in order to facilitate the contact between the metal mesh and the inner side of the smart bracelet or the inner side of the watch, the metal mesh can be glued to the inner side of the smart bracelet or the smart watch.

[0078] In this embodiment, when providing the metal mesh, it may be considered to be wound around the device under test 23 so as to contact the device under test 23. This winding method facilitates simulating a real-life scenario of a person holding the device under test 23. Furthermore, in some embodiments, if the contact area between the human body and the device under test 23 is the inner surface of the device under test 23, the metal mesh may be adhered to the inner surface of the device under test 23 to simulate the user's contact with the inner surface of the device under test 23.

[0079] For example, when conductive medium 21 is a metal foil, which is a flexible conductive medium, the device under test 23 is a remote control. When selecting a flexible conductive medium, readily available metal foils such as aluminum foil or copper foil can be selected. However, compared to metal mesh, metal foil has a certain degree of rigidity. Therefore, when metal foil is wrapped around the first area of the remote control, the contact between the remote control and the metal foil is less secure. Compared to a more rigid conductive medium such as sheet metal, the contact between the metal foil and the remote control is more secure. To avoid the above technical issues, in this embodiment, when metal foil is selected as a flexible conductive medium, it is possible to consider providing a fixing member. Examples of such fixing members include cable ties, tape, and rope.

[0080] like Figure 7 As shown, Figure 7 This is a schematic diagram of a metal foil arrangement provided in an embodiment of the present application. Figure 7 As shown in Figure (a), Figure 7 Figure (a) is a top view of the remote control, where the surface is wrapped with metal foil 41, and the metal foil 41 completely wraps the upper surface where the remote control button 32 is located. Figure 7 Figure (b) is a left view of the remote control. When the conductive medium is a metal foil 41, the dotted line in the figure represents the gap in the remote control housing. After the metal foil is wrapped around the surface shown in Figure (a), it can continue to be wrapped above the gap shown in Figure (b). Similarly, the surface of the remote control from the right view and the bottom surface of the remote control opposite to the surface from the top view are also wrapped with a conductive medium. In addition, Figure 7Figure (c) is a front view of the remote control. In Figure (c), the dotted line represents the gap in the surface of the remote control, and the surface shown is also wrapped with metal foil 41. In other words, the metal foil 41 wraps around the remote control once or multiple times and also covers the surface shown in the front view of the remote control.

[0081] Furthermore, in order to increase the tightness of the contact between the metal foil and the remote control, after wrapping the metal foil, one or more tie wraps can be placed on the outside of the metal foil. Figure 8 As shown, Figure 8 A schematic diagram of another metal foil setting method provided in an embodiment of the present application shows that two circles of cable ties 42 are wrapped around the surface of the metal foil 41, so that the metal foil 41 can contact the remote control more closely and more accurately simulate the contact effect when the remote control comes into contact with a human hand.

[0082] In some embodiments, here, the device to be tested 23 is taken as an example of a smart bracelet. When the device to be tested 23 is a smart bracelet, in an actual application scenario, when a person wears the smart bracelet on his arm, the inner surface of the smart bracelet is in contact with the person's arm. When the person's arm carries static electricity, the static electricity will pass through the person's arm to the smart bracelet. When a person wears the smart bracelet on his arm, the outer surface of the smart bracelet is in contact with a low-potential object such as a table or a coffee table. At this time, the smart bracelet will release static electricity through the outer surface of the smart bracelet. At this time, in order to make the metal mesh contact with the inner surface of the smart bracelet, in this embodiment, Figure 1 Based on the device shown, the provided test equipment further includes a support component. The first area where the conductive medium 21 contacts the device under test 23 is the inner surface of the smart wristband; the support component is used to support the metal mesh so that the metal mesh contacts the inner surface of the smart wristband.

[0083] For example, in this embodiment, in order to allow the metal mesh to contact the inner surface of the smart bracelet, the testing device also includes a support component. During the electrostatic test process, the metal mesh can maintain contact with the inner surface of the smart bracelet through the support component.

[0084] In one example, Figure 9 A schematic diagram of another metal mesh configuration method provided in an embodiment of the present application. Figure 9In the figure, a wristband 51 and a support component 52 are included. The support component 52 can be set as a cylindrical structure, or can be set based on the internal shape of the wristband 51. A metal mesh (represented by diagonal hatching in the figure) can be wrapped around the surface of the support component 52. Afterwards, the metal mesh can be in contact with the inner surface of the wristband 51 through the support component 52. In addition, the metal mesh can also be connected to a wire, and then electrically connected to the first impedance element 22 through the wire and then grounded. It should be noted that in order to improve the tightness of the contact between the conductive medium provided on the support component and the inner side of the smart wristband, when setting the support component, the error between the shape of the support component and the internal shape of the wristband should be as small as possible to improve the accuracy of the subsequent electrostatic detection results.

[0085] In this embodiment, when setting the metal mesh, it can be considered to set the metal mesh on a supporting component, and then by setting the supporting component, the metal mesh can be in contact with the inside of the smart bracelet, so that in the subsequent electrostatic test process, the metal mesh can simulate the contact between the human body and the smart bracelet, making the electrostatic test results more accurate. It should be noted that in this embodiment, only the smart bracelet is used as an example. Other wearable and contactable annular objects such as smart collars and smart watches can adopt the above-mentioned supporting component method when performing electrostatic testing, so that the metal mesh is in contact with the inside of the above-mentioned annular object.

[0086] In some embodiments, the device to be tested 23 is smart glasses; the first area is a frame or a temple.

[0087] For example, the testing device provided in this embodiment can also be used to test smart glasses. Furthermore, when testing smart glasses, electrostatic testing can be considered for the smart glasses in two configurations: one configuration with the smart glasses with the temples open, and the other configuration with the smart glasses with the temples closed.

[0088] For example, Figure 10 This is a schematic diagram of another configuration of a conductive medium provided in an embodiment of the present application. Figure 10 As shown in the figure, when the temples 61 of the smart glasses are in an open state, if the temples 61 of the smart glasses are provided with electronic components or metal materials, when the smart glasses need to be tested, the conductive medium 21 can be placed in the middle of the temples 61. During the subsequent testing process, static electricity can be emitted to the areas of the smart glasses that are not in contact with the conductive medium 21, thereby simulating the process of a person holding the temples of the smart glasses and touching other low-potential objects, and the human body discharging electricity through the smart glasses to the other low-potential objects.

[0089] For example, Figure 11 This is a schematic diagram of another arrangement of a conductive medium provided in an embodiment of the present application. Figure 11 As shown, Figure 11 In the figure, the temples of the smart glasses are in a closed state as an example for explanation. As shown in the figure, when the temples of the smart glasses are in a closed state, the contact area between the human hand and the smart glasses is the frame. In this case, it is possible to consider setting the conductive medium 21 at a certain area of the frame. For example, Figure 11 In the embodiment, the conductive medium 21 can be placed on the right side of the eyeglass frame. Specifically, when the conductive medium 21 is a metal mesh, the metal mesh can be wrapped around the right side of the eyeglass frame, or the right side of the eyeglass frame and the right side of the eyeglass leg can be wrapped together, thereby simulating a scenario in which a user places the closed eyeglasses on a low-potential object by touching the eyeglass frame in actual use, and the user discharges electricity to the low-potential object through the closed eyeglass frame and / or the eyeglass leg.

[0090] In this embodiment, when performing an electrostatic test on the smart glasses, different settings of the conductive medium 21 are used for the temples of the smart glasses in different states, thereby making the above-mentioned electrostatic test phenomenon more consistent with the scenario of the human body discharging to other objects through the smart glasses, thereby improving the accuracy of the electrostatic test.

[0091] In some embodiments, the first impedance element 22 includes a first resistor and a capacitor; one end of the first resistor is electrically connected to the conductive medium 21 , the other end of the first resistor is connected to one end of the capacitor, and the other end of the capacitor is grounded.

[0092] Exemplarily, in order to simulate the actual use scenario of the user when using the device to be tested 23, the first impedance element 22 in the present embodiment includes a first resistor element and a capacitor element. Wherein, the first resistor element and the capacitor element are connected in series, and one end of the first resistor element is connected to the conductive medium 21, and the other end of the capacitor element is grounded. After the electrostatic device injects static electricity into the device to be tested 23, since the device to be tested 23 is in contact with the conductive medium 21, the static electricity injected into the device to be tested 23 can be transmitted to the first resistor element connected to the conductive medium 21 and the capacitor element connected to the first resistor element through the conductive medium 21.

[0093] In one example, the resistance value of the first resistor element may be set to 510 ohms, and the capacitance value of the capacitor element may be set to 220 pF.

[0094] It should be noted that, in some examples, when setting the first impedance element 22, the first impedance element can be adjusted according to the actual test scenario. For example, the first impedance element 22 can include at least one resistor and / or at least one capacitor. Alternatively, the first impedance element 22 can include at least one resistor and at least one capacitor connected in parallel, without specific limitation.

[0095] In this embodiment, when setting the first impedance element 22, the first impedance element 22 may include a first resistance element and a capacitance element. By setting the first resistance element and the capacitance element, the first impedance element 22 can effectively simulate the user's real impedance and improve the accuracy of the test.

[0096] In some embodiments, Figure 12 A structural diagram of another test device for testing a device to be tested provided in an embodiment of the present application, Figure 2 In addition to the test equipment shown in FIG. 1 , the electrostatic test equipment provided in this embodiment further includes a horizontal coupling plate 81, a second impedance element 82, and an insulating pad 83. The horizontal coupling plate 81 is placed on the insulation test platform 20, and the insulating pad 83 is placed on the insulation test platform 20. The device under test 23 and the conductive medium 21 are placed on the insulating pad 83. The insulating pad 83 is used to prevent all electrostatic charges received by the device under test 23 from passing through the insulating pad 83. One end of the second impedance element 82 is electrically connected to the horizontal coupling plate 81, and the other end of the second impedance element 82 is grounded.

[0097] For example, the test equipment provided in this embodiment includes an electrostatic device, an insulation test platform 20, a conductive medium 21, a first impedance element 22, an insulating pad 83, a horizontal coupling plate 81, and a second impedance element 82. The horizontal coupling plate 81 is disposed on the insulation test platform 20, and the insulating pad 83 is disposed on the horizontal coupling plate 81.

[0098] In one example, the center point of the insulation pad 83 coincides with the center point of the insulation test bench 20 , that is, the insulation pad 83 is located in the central area of the insulation test bench 20 .

[0099] The device under test 23 and the conductive medium 21 are placed on an insulating pad 83, with the device under test 23 in contact with the conductive medium 21; the conductive medium 21 is electrically connected to the first impedance element 22, and the first impedance element 22 is grounded. In addition, the horizontal coupling plate 81 is connected to the second impedance element 82, and the second impedance element 82 is grounded. The horizontal coupling plate 81 can be used to simulate whether static electricity in the environment where the device under test 23 is located will affect the performance of the device under test 23. For example, during testing, an electrostatic device can be used to discharge static electricity to the horizontal coupling plate 81, thereby causing static electricity to exist in the environment surrounding the device under test 23. Alternatively, during electrostatic testing, a contact discharge method can be used to simulate the process of discharging static electricity through the device under test 23 when the human body comes into contact with the device under test 23.

[0100] In addition, when setting the insulating pad 83, the thickness of the insulating pad 83 can be greater than or equal to 10 cm, so that the insulating pad 83 is used to prevent all electrostatic charges received by the device to be tested 23 from passing through the insulating pad 83, that is, to ensure that the electrostatic charges received by the device to be tested 23 are transmitted from the conductive medium 21 in contact with the device to be tested 23 to the first impedance element 22 connected to the conductive medium 21, thereby preventing the electrostatic charges contacted by the device to be tested 23 from being transmitted along other paths, thereby making the electrostatic test results more accurate.

[0101] In one example, Figure 12 The provided test equipment can also be used to test other non-handheld devices to be tested. For example, when testing a non-handheld device to be tested, an insulating pad with a smaller thickness value can be selected, so that when testing the non-handheld device to be tested, the electrostatic charge received by the non-handheld device to be tested can pass through the insulating pad and be transmitted through the horizontal coupling plate in contact with the insulating pad and the second impedance element connected to the horizontal coupling plate. That is, the test equipment provided in this embodiment can be applicable to different types of devices to be tested. When testing a handheld device, an insulating pad with a larger thickness value and a conductive medium can be selected to perform the above-mentioned test on the device to be tested. For non-handheld devices, an insulating pad with a smaller thickness value can be selected for testing, thereby realizing the reuse of electrostatic testing equipment and improving equipment utilization.

[0102] In one example, the second impedance element 82 includes a second resistance element and a third resistance element, one end of the second resistance element is electrically connected to the horizontal coupling plate 81, the other end of the second resistance element is electrically connected to one end of the third resistance element, and the other end of the third resistance element is grounded.

[0103] For example, when the second impedance element 82 is provided, the second impedance element 82 may include a second resistor element and a third resistor element. The second resistor element and the third resistor element are connected in series, and one end of the second resistor element may be electrically connected to the horizontal coupling plate 81, while the other end of the third resistor element is grounded. Furthermore, by providing the second impedance element 82, the electrostatic charge transmitted from the electrostatic device to the horizontal coupling plate 81, or the charge in the device under test 23 that passes through the insulating block and reaches the horizontal coupling plate 81, can be transmitted to the second impedance element 82 and ultimately released through the second impedance element 82. In one example, the resistance of the second resistor element and the third resistor element is both 470 kiloohms.

[0104] The test equipment in this embodiment, by providing a conductive medium 21 and a first impedance element 22, can be used to simulate the discharge path when a user discharges electricity through the device under test 23 to other low-potential objects, thereby improving test efficiency. Furthermore, compared to the provision of an insulating pad 83 in related art, the insulating pad 83 in this embodiment is thickened, thereby enabling the insulating pad 83 to completely prevent the electrostatic charge in the device under test 23 from passing through the insulating block. Furthermore, the test device in this embodiment only requires thickening the insulating pad 83 and providing the conductive medium 21 on the device under test 23, based on the test device in the related art, to complete the construction of the test equipment. This improves the reuse rate of the test equipment in related art and reduces the cost of the test equipment in this embodiment.

[0105] An embodiment of the present application provides an electrostatic testing method, which includes the following steps: placing a device to be tested and a conductive medium on an insulating test bench, wherein the device to be tested is in contact with the conductive medium; controlling an electrostatic device to emit static electricity to the device to be tested, so that the conductive medium transmits the charge transmitted after the device to be tested contacts the static electricity to a first impedance element connected to the conductive medium, wherein the first impedance element is grounded.

[0106] In a possible implementation, controlling the electrostatic device to emit static electricity to the device under test includes: controlling the electrostatic device to emit static electricity to a portion of the device under test that is not in contact with the conductive medium.

[0107] For example, in order to simulate the phenomenon that when a user holds the device to be tested, the static electricity generated by the user will be discharged to other objects through the device to be tested, this embodiment controls the electrostatic device to discharge to the device to be tested set on the insulating platform, so that the charge in the device to be tested can be transmitted to the conductive medium in contact with the device to be tested. Thereafter, the conductive medium transmits the received charge to the first impedance element connected to the conductive medium, and then simulates the human body impedance through the first impedance element, and uses the conductive medium to simulate the human hand.

[0108] In one example, based on Figure 2 When the test device in the electrostatic test is performed on the device to be tested, if the device to be tested has functions such as image display or audio playback, during the electrostatic test, it can be determined whether the device to be tested has passed the electrostatic test by detecting whether the image displayed or the audio played by the device to be tested is normal. The image displayed or the audio played by the device to be tested can be sent to the device to be tested by an external device, or can be stored in the device to be tested itself, and no specific restrictions are made here.

[0109] In one example, if the device to be tested cannot play displayed images or audio, such as a handheld remote control, the device to be tested can be discharged through an electrostatic device, and then the device to be tested can be placed in other test devices to test the button functions of the handheld remote control through the other test devices.

[0110] In some embodiments, when using an electrostatic device to emit static electricity to the device under test, the following steps can be performed:

[0111] Repeat the following steps until a preset first stop condition is reached: control the electrostatic device to emit static electricity of a first polarity to a portion of the device to be tested that is not in contact with the conductive medium.

[0112] Repeat the following steps until a preset second stop condition is reached: control the electrostatic device to emit static electricity of a second polarity to a portion of the device to be tested that is not in contact with the conductive medium.

[0113] For example, in this embodiment, since the polarity of the charge carried by the human body is not fixed, that is, the charge carried by the human body may be positive or negative. Therefore, during the electrostatic test, the electrostatic device needs to inject electrostatic charges of different polarities into the device under test. Specifically, during the electrostatic test, the electrostatic device can inject static electricity of a first polarity into the device under test until a preset first stop condition is reached. The preset first stop condition can be the number of times the electrostatic device emits static electricity of the first polarity. Similarly, the second stop condition can be the number of times the electrostatic device emits static electricity of a second polarity, where the first polarity and the second polarity represent two different polarities. For example, in an actual test, after injecting positive electrostatic charges into the device under test 10 times, negative electrostatic charges are injected into the device under test 10 times. Furthermore, the above method can simulate a scenario where a human body, carrying static electricity of different polarities, discharges static electricity through the device under test to another low-potential object. It should be noted that the preset first and second stop conditions can also be pre-set discharge times, which are not specifically limited in this embodiment.

[0114] In some embodiments, during the electrostatic test process, the contact area between the conductive medium and the device to be tested can be continuously changed. Figure 6 As shown in the figure, when a person holds the remote control, the holding part is generally the wrapped position of the metal mesh in the figure. When the above-mentioned conductive medium setting method is used for electrostatic testing, in order to avoid the electrostatic charge injected by the electrostatic device into the device to be tested being transmitted to the conductive medium from the same gap in the remote control to the metal mesh each time, the wrapped position of the metal mesh can be changed during the test process, that is, the metal mesh can be wrapped in Figure 6 The area not covered by the metal mesh, then the electrostatic device can be applied to the part where people often hold their hands (i.e. the current Figure 6 By injecting charges into different gaps in the metal mesh (shown in the figure), the diversity of the transmission paths of the electrostatic charge in the remote control is increased, and the accuracy of the electrostatic test is improved.

[0115] The electrostatic transmission path in this embodiment's electrostatic testing method effectively simulates the transmission path of a human body discharging a charge through the device under test to other low-voltage devices in real-world scenarios, thereby improving the effectiveness of the electrostatic test. Furthermore, this embodiment imposes no restrictions on the polarity, magnitude, number, or frequency of the electrostatic charge transmitted from the electrostatic device to the device under test. Specifically, the design can be tailored to the specific electrostatic requirements of the device under test.
