The scope of this disclosure is not limited to this. Those skilled in the art should be able to understand that some changes, substitutions, and substitutions may be made without departing from the spirit and structure of the disclosure.In the embodiments of the present disclosure, the component symbols may be used repeatedly, and the several embodiments of the present disclosure may share the same component symbols, but the feature components used in one embodiment are not necessarily used in another embodiment.
第1圖係依據本揭露之一第一實施例實現一靜電檢測裝置10之配置圖。靜電檢測裝置10包括一第一導電單元11、一第二導電單元12、一電容13、一導線14、一絕緣墊15和一外殼16。如第1圖所示，第一導電單元11和第二導電單元12皆電性連接至電容13之一第一端。導線14之一第一端耦接至電容13之一第二端。導線14之一第二端穿過絕緣墊15以做為一檢測接腳。在本揭露之第一實施例中，第一導電單元11和第二導電單元12皆係由鋁箔片組成，但本揭露不限定於此，銅、錫、金、銀或任何可帶電導體皆未脫離本揭露之範疇。電容13係電容值為1PF至1UF之積層陶瓷電容器，但本揭露亦不限定於此。絕緣墊15係一塑膠墊，外殼16係玻璃材質或三聚氰胺材質，但本揭露亦不限定於此。絕緣墊15和外殼16形成一空間以共同包覆第一導電單元11、第二導電單元12和電容13。1 is a configuration diagram of an electrostatic detecting device 10 according to a first embodiment of the present disclosure. The static electricity detecting device 10 includes a first conductive unit 11, a second conductive unit 12, a capacitor 13, a wire 14, an insulating pad 15, and a casing 16. As shown in FIG. 1 , the first conductive unit 11 and the second conductive unit 12 are electrically connected to one of the first ends of the capacitor 13 . One of the first ends of the wires 14 is coupled to one of the second ends of the capacitors 13. The second end of one of the wires 14 passes through the insulating mat 15 as a detecting pin. In the first embodiment of the present disclosure, the first conductive unit 11 and the second conductive unit 12 are all composed of aluminum foil, but the disclosure is not limited thereto, and copper, tin, gold, silver or any electrable conductor is not Beyond the scope of this disclosure. The capacitor 13 is a multilayer ceramic capacitor having a capacitance value of 1 PF to 1 UF, but the present disclosure is not limited thereto. The insulating mat 15 is a plastic mat, and the outer casing 16 is made of glass or melamine, but the disclosure is not limited thereto. The insulating pad 15 and the outer casing 16 form a space to collectively cover the first conductive unit 11, the second conductive unit 12, and the capacitor 13.
在本揭露之第一實施例中，靜電檢測裝置10在未偵測靜電時，第一導電單元11和第二導電單元12係閉合的。當靜電檢測裝置10之該檢測接腳偵測到一靜電放電電位時，第一導電單元11和第二導電單元12會因電容13上的電位差而帶電。由於第一導電單元11和第二導電單元12帶有相同電性的電荷，第一導電單元11和第二導電單元12彼此之間會產生一庫倫作用力而彼此相斥，使得第一導電單元11和第二導電單元12打開而形成一夾角θ。當該檢測接腳所偵測到之靜電放電電位越大，電容13上的電位差增加而增強第一導電單元11和第二導電單元12之間的庫倫作用力。增強的庫倫作用力會使得第一導電單元11和第二導電單元12之間夾角θ的角度更大。In the first embodiment of the present disclosure, when the static electricity detecting device 10 does not detect static electricity, the first conductive unit 11 and the second conductive unit 12 are closed. When the detecting pin of the static electricity detecting device 10 detects an electrostatic discharge potential, the first conductive unit 11 and the second conductive unit 12 are charged by the potential difference on the capacitor 13. Since the first conductive unit 11 and the second conductive unit 12 have the same electric charge, the first conductive unit 11 and the second conductive unit 12 generate a Coulomb force and repel each other, so that the first conductive unit 11 and the second conductive unit 12 are opened to form an included angle θ. When the detection pin detects the electrostatic discharge potentialLarge, the potential difference across the capacitor 13 increases to enhance the Coulomb force between the first conductive unit 11 and the second conductive unit 12. The enhanced Coulomb force causes the angle of the angle θ between the first conductive unit 11 and the second conductive unit 12 to be larger.
在本揭露之第一實施例中，為了減少影響第一導電單元11和第二導電單元12之間夾角θ的變化因子(例如空氣擾動)，絕緣墊15和外殼16所形成的空間會被抽為真空。一使用者若要檢測一待測電路之一第一節點上是否發生靜電放電事件，使用者即可將靜電檢測裝置10之檢測接腳連接至該第一節點。使用者藉由觀測靜電檢測裝置10中之第一導電單元11和第二導電單元12是否張開得知是否發生一靜電放電事件。當靜電檢測裝置10偵測到一靜電放電事件發生時，使用者可觀測靜電檢測裝置10中之第一導電單元11和第二導電單元12之間的夾角θ大小得知該第一節點的靜電放電電位大小。In the first embodiment of the present disclosure, in order to reduce the variation factor (for example, air disturbance) that affects the angle θ between the first conductive unit 11 and the second conductive unit 12, the space formed by the insulating pad 15 and the outer casing 16 is drawn. It is a vacuum. If a user wants to detect whether an electrostatic discharge event occurs on the first node of one of the circuits to be tested, the user can connect the detection pin of the static electricity detecting device 10 to the first node. The user determines whether an electrostatic discharge event has occurred by observing whether the first conductive unit 11 and the second conductive unit 12 in the static electricity detecting device 10 are opened. When the static electricity detecting device 10 detects an electrostatic discharge event, the user can observe the angle θ between the first conductive unit 11 and the second conductive unit 12 in the static detecting device 10 to obtain the static electricity of the first node. The size of the discharge potential.
在本揭露之第一實施例中，由於靜電檢測裝置10之第一導電單元11和第二導電單元12即使在靜電事件結束之後，仍會維持在靜電事件發生時所張開的角度。本揭露利用此一特性，將靜電檢測裝置10應用至一電子產品之中，以檢測該電子產品是否發生一靜電放電事件。例如，將靜電檢測裝置10設置在一電子產品的輸入/輸出接腳上，或是人體容易接觸到的導電件部份。此時，若該電子產品在被使用時曾經發生過靜電放電事件，靜電電荷會致使靜電檢測裝置10之第一導電單元11和第二導電單元12互斥而張開。該電子產品的維修人員即可從靜電檢測裝置10中之第一導電單元11和第二導電單元12是否張開來判斷該電子產品是否遭遇過靜電干擾。此外，該電子產品中第一導電單元11和第二導電單元12的張開角度亦反應了靜電電量大小。這能讓在送修該電子產品時，該電子產品的修理人員得知該電子產品是否曾遭受靜電干擾破壞以及該電子產品所承受靜電放電的電量大小。In the first embodiment of the present disclosure, since the first conductive unit 11 and the second conductive unit 12 of the static electricity detecting device 10 maintain the angle opened at the occurrence of the electrostatic event even after the end of the electrostatic event. The present disclosure utilizes this feature to apply the static electricity detecting device 10 to an electronic product to detect whether an electrostatic discharge event has occurred in the electronic product. For example, the static electricity detecting device 10 is placed on an input/output pin of an electronic product or a portion of the conductive member that is easily accessible to the human body. At this time, if the electronic product has been subjected to an electrostatic discharge event when it is used, the electrostatic charge causes the first conductive unit 11 and the second conductive unit 12 of the static electricity detecting device 10 to be mutually exclusive and opened. The maintenance personnel of the electronic product can judge whether the electronic product has been subjected to static interference from whether the first conductive unit 11 and the second conductive unit 12 in the static electricity detecting device 10 are opened. In addition, the electronThe opening angles of the first conductive unit 11 and the second conductive unit 12 in the product also reflect the magnitude of the electrostatic charge. This allows the repairman of the electronic product to know whether the electronic product has been subjected to electrostatic interference damage and the amount of static electricity discharged by the electronic product when the electronic product is sent for repair.
此外，值得注意的是由於靜電檢測裝置10設置了電容13，靜電檢測裝置10具有阻隔直流電源感應的功能。如果靜電檢測裝置10並未設置電容13而使第一導電單元11和第二導電單元12直接電性連接至導線14。此時，導線14之檢測接腳所偵測的節點上的直流電壓會感應到第一導電單元11和第二導電單元12上，而使得第一導電單元11和第二導電單元12無法張開(這是由於第一導電單元11、第二導電單元12和導線14皆為等電位，使得第一導電單元11和第二導電單元中並未帶有電荷)。因此，本揭露之靜電檢測裝置10可以有效偵測到待測電路中的靜電放電突波。Further, it is worth noting that since the electrostatic detecting device 10 is provided with the capacitor 13, the static detecting device 10 has a function of blocking the DC power source sensing. If the static electricity detecting device 10 is not provided with the capacitor 13 , the first conductive unit 11 and the second conductive unit 12 are directly electrically connected to the wire 14 . At this time, the DC voltage on the node detected by the detecting pin of the wire 14 is sensed on the first conductive unit 11 and the second conductive unit 12, so that the first conductive unit 11 and the second conductive unit 12 cannot be opened. (This is because the first conductive unit 11, the second conductive unit 12, and the wires 14 are all equipotential such that no charge is present in the first conductive unit 11 and the second conductive unit). Therefore, the static electricity detecting device 10 of the present disclosure can effectively detect the electrostatic discharge surge in the circuit to be tested.

In general, the ESD voltage ranges from approximately 1 KV to 8 KV up to 15 KV. Since the capacitor 13 in the static electricity detecting device 10 is an open circuitThe capacitance withstand voltage of the capacitor 13 is not limited.
第2A圖、第2B圖、第2C圖、第2D圖和第2E圖說明上述規格之靜電檢測裝置10在偵測不同靜電放電電位時，第一導電單元11和第二導電單元12張開夾角θ的角度。首先，由第2A圖可知，當靜電檢測裝置10偵測到2KV之靜電放電電位時，第一導電單元11和第二導電單元12張開之夾角θ約為5度角。由第2B圖可知，當靜電檢測裝置10偵測到4KV之靜電放電電位時，第一導電單元11和第二導電單元12張開之夾角θ約為10度角。由第2C圖可知，當靜電檢測裝置10偵測到6KV之靜電放電電位時，第一導電單元11和第二導電單元12張開之夾角θ約為15度角。由第2D圖可知，當靜電檢測裝置10偵測到8KV之靜電放電電位時，第一導電單元11和第二導電單元12張開之夾角θ約為20度角。最後，由第2E圖可知，當靜電檢測裝置10偵測到10KV之靜電放電電位時，第一導電單元11和第二導電單元12張開之夾角θ約為25度角。2A, 2B, 2C, 2D, and 2E illustrate the opening of the first conductive unit 11 and the second conductive unit 12 when the electrostatic detecting device 10 of the above specification detects different electrostatic discharge potentials. The angle of θ. First, as can be seen from FIG. 2A, when the electrostatic detecting device 10 detects an electrostatic discharge potential of 2 KV, the angle θ between the first conductive unit 11 and the second conductive unit 12 is about 5 degrees. As can be seen from FIG. 2B, when the electrostatic detecting device 10 detects an electrostatic discharge potential of 4 kV, the angle θ between the first conductive unit 11 and the second conductive unit 12 is about 10 degrees. As can be seen from FIG. 2C, when the electrostatic detecting device 10 detects an electrostatic discharge potential of 6 kV, the angle θ between the first conductive unit 11 and the second conductive unit 12 is about 15 degrees. As can be seen from FIG. 2D, when the electrostatic detecting device 10 detects an electrostatic discharge potential of 8 kV, the angle θ between the first conductive unit 11 and the second conductive unit 12 is about 20 degrees. Finally, it can be seen from FIG. 2E that when the electrostatic detecting device 10 detects an electrostatic discharge potential of 10 kV, the angle θ between the first conductive unit 11 and the second conductive unit 12 is about 25 degrees.

以第一積體電路元件34為例，設計者會在其電源接腳341和接地接腳342設置對應的靜電放電保護電路。因此，設計者在研發階段需要知道第一積體電路元件34之電源接腳341和接地接腳342可能會到承受多大的靜電放電電壓，以設計符合第一積體電路元件34需求的靜電放電保護電路。本揭露之第三實施例為了達成上述目的，設計者會分別設置上述第一實施例的一靜電檢測裝置10在第一積體電路元件34之電源接腳341和接地接腳342上。接著，設計者施加一靜電檢測電壓於電路板裝置30之輸入/輸出接腳32，並判讀每一靜電檢測裝置10所顯示靜電放電電位大小。藉由上述方法，設計者可以設計符合第一積體電路元件34之電源接腳341和接地接腳342所需的靜電放電保護電路。同理，設計者亦能設計符合第二積體電路元件35之電源接腳351和接地接腳352所需的靜電放電保護電路，或是分別符合輸入/輸出接腳32、訊號接腳33和電源轉換器36之接地接腳362所需的靜電放電保護電路。Taking the first integrated circuit component 34 as an example, the designer sets a corresponding electrostatic discharge protection circuit on the power pin 341 and the ground pin 342. Therefore, the designer needs to know how much electrostatic discharge voltage the power pin 341 and the ground pin 342 of the first integrated circuit component 34 may withstand during the development phase to design an electrostatic discharge that meets the requirements of the first integrated circuit component 34. protect the circuit. In the third embodiment of the present disclosure, in order to achieve the above object, the designer separately sets the first realA static electricity detecting device 10 of the embodiment is on the power pin 341 and the ground pin 342 of the first integrated circuit component 34. Next, the designer applies an electrostatic detection voltage to the input/output pins 32 of the circuit board device 30, and interprets the magnitude of the electrostatic discharge potential displayed by each of the static electricity detecting devices 10. By the above method, the designer can design an electrostatic discharge protection circuit that is required to conform to the power pin 341 and the ground pin 342 of the first integrated circuit component 34. Similarly, the designer can also design an ESD protection circuit that meets the power pin 351 and the ground pin 352 of the second integrated circuit component 35, or respectively conforms to the input/output pin 32, the signal pin 33, and The ESD protection circuit required for the ground pin 362 of the power converter 36.
此外，當電路板裝置30在上電狀態時，靜電檢測裝置10中的第一導電單元11和第二導電單元12帶有零電位而閉合。此時，若有一靜電放電突波經過靜電檢測裝置10時，由於靜電檢測裝置10所設置電容13具有阻隔直流電源感應的功能，第一導電單元11和第二導電單元會因感應到靜電電位差而張開，若靜電檢測裝置10未設置電容13，當電路板裝置30在上電狀態且有一靜電放電突波經過靜電檢測裝置10時，由於第一導電單元11和第二導電單元12與靜電檢測裝置10所設置的位置等電位，並不會有電荷變化，則第一導電單元11和第二導電單元12仍維持閉合。因此，在電路板裝置30上電時，設置在電源接腳341和電源接腳351上之靜電檢測裝置10得以檢測是否有一靜電放電突波通過對應之電源接腳341或是電源接腳351，亦即檢測電源接腳341或是電源接腳351是否發生一靜電放電事件。同理，當電路板裝置30在未上電狀態時，若有一靜電放電突波經過靜電檢測裝置10時，第一導電單元11和第二導電單元亦會因感應到靜電電位差而張開。因此，設計者在電路板裝置30研發過程中之不同情形下，皆能應用本揭露之靜電檢測裝置10檢測電路板裝置30。Further, when the circuit board device 30 is in the power-on state, the first conductive unit 11 and the second conductive unit 12 in the static electricity detecting device 10 are closed with zero potential. At this time, if an electrostatic discharge surge passes through the static electricity detecting device 10, since the capacitor 13 provided in the static electricity detecting device 10 has a function of blocking the direct current power source sensing, the first conductive unit 11 and the second conductive unit may be affected by the electrostatic potential difference. If the static electricity detecting device 10 is not provided with the capacitor 13, when the circuit board device 30 is in the power-on state and an electrostatic discharge surge passes through the static electricity detecting device 10, the first conductive unit 11 and the second conductive unit 12 and the static electricity detecting The position of the device 10 is equipotential, and there is no charge change, and the first conductive unit 11 and the second conductive unit 12 remain closed. Therefore, when the circuit board device 30 is powered on, the static electricity detecting device 10 disposed on the power pin 341 and the power pin 351 can detect whether an electrostatic discharge surge passes through the corresponding power pin 341 or the power pin 351. That is, whether the power pin 341 or the power pin 351 detects an electrostatic discharge event. Similarly, when the circuit board device 30 is in an unpowered state, if an electrostatic discharge surge passes through the static electricity detecting device 10, the first conductive unit 11 and the second conductive guideThe electrical unit will also open due to the difference in electrostatic potential. Therefore, the designer can detect the circuit board device 30 by applying the static electricity detecting device 10 of the present disclosure in different situations during the development of the circuit board device 30.
