Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, and in particular to a cathode mounting device. Background Technology

[0002] In vertical electroplating processes, the cathode rack directly impacts PCB plating quality, production efficiency, and overall cost control, ultimately determining the success of the process. In actual production, the cathode rack needs two key properties: First, it must provide stable fixation. In high-speed production lines, it must firmly clamp the edges of the PCB, resisting the impact of the plating solution, equipment vibration, and external forces during rapid transfer, preventing the PCB from shaking, tilting, or falling off, thus ensuring the continuity of the plating process. Second, it needs good shape retention. For thin PCBs, uniform and stable clamping force is required to prevent warping and deformation in the high-temperature plating solution, ensuring the board remains flat and providing a foundation for a uniform plating layer.

[0003] The cathode racks in existing mainstream vertical electroplating equipment adopt a structural design that uses a single unidirectional sprocket device engaged with a conveyor chain. While this structure can transport the cathode racks, it lacks an effective mechanism to limit their movement. As a result, when the conveying and transfer mechanism pushes the cathode racks into the conveyor track, relative displacement easily occurs between the cathode racks along the conveying direction, causing irregular fluctuations in the spacing between the cathode racks. This can easily lead to uneven current distribution at the edges of the PCB board, resulting in excessive or insufficient plating thickness at the edges or in localized areas of the board. This not only reduces the yield rate but also increases costs due to rework and material waste. Utility Model Content

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A cathode mounting device is movably mounted inside an electroplating tank. A conveying and transferring device within the electroplating tank is capable of pushing the cathode mounting device to move along the conveying direction of a conveying chain within the conveying and transferring device. The cathode mounting device includes:

[0007] A cathode mounting mechanism is disposed inside the electroplating tank;

[0008] The conveying limiting mechanism includes a first limiting component and a second limiting component. Along the conveying direction of the conveying chain, the first limiting component and the second limiting component are movably disposed at intervals on the cathode mounting mechanism. The first limiting component includes a first one-way sprocket that is rotatably disposed, and the second limiting component includes a second one-way sprocket that is rotatably disposed.

[0012] The first one-way bearing is disposed at the first end of the first mounting member, and the second end of the first mounting member is rotatably connected to the first fixed seat through the first connecting shaft. The first fixed seat is disposed in the cathode mounting mechanism.

[0013] As a further technical solution, the first limiting component also includes a first torsion spring, which is sleeved on the first connecting shaft, and the two first torque shafts of the first torsion spring respectively abut against the first mounting member and the first fixing seat.

[0014] As a further technical solution, the first limiting component also includes a first mounting component and a first fixing seat;

[0015] The first one-way bearing is disposed at the first end of the first mounting member, the second end of the first mounting member is provided with a slider, the first fixed seat is disposed on the cathode hanger mechanism, and the side of the first fixed seat opposite to the cathode hanger mechanism is provided with a sliding groove extending in the vertical direction, and the slider slides in cooperation with the sliding groove.

[0016] As a further technical solution, the first limiting component also includes a compression spring and / or a tension spring. The upper end of the first fixed base is provided with a first auxiliary part, and the lower end is provided with a second auxiliary part. Both the first auxiliary part and the second auxiliary part extend toward the direction close to the first mounting member.

[0017] The upper end of the compression spring is connected to the first auxiliary part, and the lower end is fixedly connected to the upper end face of the first mounting member. The upper end of the tension spring is connected to the lower end face of the first mounting member, and the lower end is connected to the second auxiliary part.

[0018] As a further technical solution, the cathode mounting device also includes a plurality of dialing components that are fixedly arranged above the conveyor chain. The plurality of dialing components are arranged one-to-one with the plurality of lifting rails, and along the conveying direction of the conveyor chain, each dialing component is located at the front end of the lifting rail.

[0019] The distance from the lower end of the dial component to the upper surface of the conveyor chain is less than the outer diameter of the first unidirectional sprocket.

[0020] As a further technical solution, the lower end face of the dial switch is configured as an inclined auxiliary surface, which is inclined downward along the conveying direction of the conveyor chain;

[0025] Compared with the prior art, the cathode mounting device provided in this utility model embodiment has the following technical advantages:

[0026] Since the first one-way sprocket in the first limiting assembly and the one-way sprocket in the second assembly rotate in opposite directions and both can engage with the conveyor chain, when the cathode mounting mechanism is placed inside the electroplating tank and transported along the conveyor chain, both the first and second one-way sprockets engage with the chain. At this time, because the first and second sprockets rotate in opposite directions, neither rotates. Therefore, by cooperating with the conveyor sprockets, the relative position of the cathode mounting mechanism on the conveyor chain is limited, thus preventing displacement of the cathode mounting mechanism relative to the conveyor chain during transport. When multiple cathode mounting... When multiple cathode mounting mechanisms are conveyed on the same conveyor chain, the relative displacement of these mechanisms along the conveyor chain direction can be avoided when the conveyor transfer device pushes them. Therefore, when multiple cathode mounting mechanisms are driven in conjunction with the conveyor chain, irregular fluctuations in the spacing between adjacent cathode mounting mechanisms can be avoided. This reduces the risk of uneven current distribution at the PCB edge, excessive or insufficient plating thickness at the edge or in local areas of the board, thereby improving yield and reducing production costs.

[0044] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0045] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0046] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0047] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0048] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0049] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0050] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0051] Combination Figures 1 to 10 As shown, the cathode mounting device provided in this embodiment is movably mounted inside the electroplating tank 10. The conveying and transferring device (not shown in the figure) in the electroplating tank 10 can push the cathode mounting device to move along the conveying direction of the conveying chain 20 in the conveying and transferring device. This cathode mounting device ensures the conveying effect of the cathode mounting mechanism 100 while limiting the cathode mounting mechanism 100 placed on the conveying chain 20, thereby improving the yield and reducing production costs. Specifically, the cathode mounting device includes a cathode mounting mechanism 100 and a conveying limiting mechanism 200. The cathode mounting mechanism 100 is disposed inside the electroplating tank 10. The conveying limiting mechanism 200 includes a first limiting component 210 and a second limiting component 220. Along the conveying direction of the conveying chain 20, the first limiting component 210 and the second limiting component 220 are movably disposed at intervals on the cathode mounting mechanism 100. The first limiting component 210 includes a first one-way sprocket 211 that is rotatably disposed, and the second limiting component 220 includes a second one-way sprocket 221 that is rotatably disposed. The rotation directions of the first one-way sprocket 211 and the second one-way sprocket 221 are opposite, and both the first one-way sprocket 211 and the second one-way sprocket 221 can mesh with the conveying chain 20.

[0052] Since the first one-way sprocket 211 rotatably disposed in the first limiting component 210 and the one-way sprocket rotatably disposed in the second component rotate in opposite directions and can both engage with the conveyor chain 20, after the cathode mounting mechanism 100 is placed in the electroplating tank 10, when the cathode mounting mechanism 100 is conveyed along with the conveyor chain 20, both the first one-way sprocket 211 and the second one-way sprocket 221 engage with the conveyor chain 20. At this time, since the first one-way sprocket 211 and the second one-way sprocket 221 rotate in opposite directions, neither of them rotates. Thus, by cooperating with the conveyor sprocket, the relative position of the cathode mounting mechanism 100 on the conveyor chain 20 is restricted, thereby preventing the cathode mounting mechanism 100 from shifting relative to the conveyor chain 20 during the conveying process. In the case of multiple cathode mounting mechanisms 100 being transported on the same conveyor chain 20, when the conveying and transfer device pushes the multiple cathode mounting mechanisms 100, relative displacement of the multiple cathode mounting mechanisms 100 along the conveying direction of the conveyor chain 20 can be avoided. Therefore, when the multiple cathode mounting mechanisms 100 are driven and cooperate with the conveyor chain 20, by controlling the distance between two adjacent cathode mounting mechanisms 100, irregular fluctuations in the distance between the multiple cathode mounting mechanisms 100 can be avoided, thereby reducing the risk of uneven current distribution at the edge of the PCB board, excessive or insufficient plating thickness at the edge or in local areas of the board, and thus improving the yield and reducing production costs.

[0053] Furthermore, in this embodiment, the direction from right to left is recorded as the conveying direction of the cathode mounting mechanism 100, and the first one-way sprocket 211 can only rotate in the clockwise direction, and the second one-way sprocket 221 can only rotate in the counterclockwise direction.

[0054] Taking one of the cathode mounting mechanisms 100 as an example, its conveying process will be further described. When the cathode mounting mechanism 100 is placed inside the electroplating tank 10 so that it is conveyed along the conveyor chain 20, the second one-way sprocket 221 engages with the conveyor chain 20, the first one-way sprocket 211 moves upward and disengages from the conveyor chain 20; with the movement of the conveyor chain 20 and the push of the transfer device, the cathode mounting machine is conveyed along the movement direction of the conveyor chain 20. Subsequently, as the conveyor chain 20 moves, when the projection of the conveyor chain 20 in the vertical direction completely covers the conveyor limiting mechanism 200, the first one-way sprocket 211 moves downward along the conveying direction. At this time, both the first one-way sprocket 211 and the second one-way sprocket 221 are engaged with the conveyor chain 20. Since the rotation directions of the first one-way sprocket 211 and the second one-way sprocket 221 are opposite, when the conveying transfer device pushes the cathode mounting mechanism 100, neither the first one-way sprocket 211 nor the second one-way sprocket 221 rotates. Therefore, by cooperating with the conveyor sprocket, the first one-way sprocket 211 and the second one-way sprocket 221 limit the relative position of the cathode mounting mechanism 100 on the conveyor chain 20. When it is necessary to remove the cathode mounting mechanism 100 from the electroplating tank 10, the first one-way sprocket 211 is moved upward, and the first one-way chain is disengaged from the conveyor chain 20. At this time, the cathode mounting machine continues to be conveyed along the movement direction of the conveyor chain 20 until the cathode mounting device is completely disengaged from the conveyor chain 20.

[0055] Furthermore, the cathode mounting device also includes multiple lifting rails 300, each lifting rail 300 being spaced apart on the same side of the conveying chain 20 along the conveying direction of the conveying chain 20. In the vertical direction, the upper end face of each lifting rail 300 is higher than the upper end face of the conveying chain 20. The first limiting component 210 also includes an auxiliary roller 212 and a first one-way bearing 213. The first one-way bearing 213 extends along the width direction of the conveying chain 20. The outer diameter of the auxiliary roller 212 is greater than or equal to the outer diameter of the first one-way sprocket 211, and both are mounted on the first one-way bearing 213. The auxiliary roller 212 can roll and cooperate with the upper end face of each lifting rail 300.

[0056] In this embodiment, the example of a cathode mounting mechanism 100 cooperating with two lifting rails 300 is used for illustration, and the two lifting rails 300 are referred to as the left lifting rail 300 and the right lifting rail 300 along the left-right direction; specifically, in conjunction with Figures 1 to 4As shown, with the movement of the conveyor chain 20 and the dragging of the transfer device, the first one-way sprocket 211 can be automatically moved upward by the engagement of the lifting rail 300 with the first one-way sprocket 211. Since the upper surface of the lifting rail 300 is higher than the upper surface of the conveyor chain 20, it ensures that the first one-way sprocket 211 completely disengages from the conveyor chain 20 during its upward movement. Specifically, when the cathode mounting mechanism 100 is placed inside the electroplating tank 10, and the cathode mounting mechanism 100 is conveyed along with the conveyor chain 20, the transfer device pushes the cathode mounting mechanism to move, the second one-way sprocket 221 engages with the conveyor chain 20, and the auxiliary roller 212 engages with the right-side lifting rail 300 to disengage the first one-way sprocket 211 from the conveyor chain 20. At this time, the cathode mounting mechanism 100 is in the first copper insertion state, as shown... Figure 1 As shown; subsequently, with the movement of the conveyor chain 20 and the continuous pushing of the transfer device, the auxiliary roller 212 falls from the right side of the track 300. The first one-way sprocket 211 and the second one-way sprocket 221 both mesh with the conveyor chain 20, and through their cooperation, the relative position of the cathode mounting mechanism 100 on the conveyor chain 20 is restricted. At this time, the cathode mounting mechanism 100 is in the second copper insertion state, as shown. Figure 2 As shown; when the cathode mounting mechanism 100 is in the second copper insertion state, the transfer device no longer pushes the cathode mounting device. After the copper insertion is completed, the transfer device does not push the cathode mounting device. With the movement of the conveyor chain 20, the auxiliary roller 212 engages with the left lifting rail 300, so that the first one-way sprocket 211 disengages from the conveyor chain 20, and the second one-way sprocket 221 engages with the conveyor chain 20. At this time, the cathode mounting mechanism 100 is in the first copper exit state, as shown. Figure 3 As shown; subsequently, while the conveyor chain 20 continues to move, the transfer device pushes the cathode mounting device so that the auxiliary roller 212 rolls and engages with the upper end face of the left lifting rail 300 until the cathode mounting device is completely disengaged from the conveyor chain 20. At this time, the cathode mounting mechanism 100 is in the second copper output state, as shown. Figure 4 As shown, in this state, the cathode mounting mechanism 100 is fully exposed to copper.

[0057] Furthermore, the cathode mounting device also includes multiple dialing components 400, each fixedly mounted above the conveyor chain 20. Each dialing component 400 corresponds to one of the multiple lifting rails 300, and along the conveying direction of the conveyor chain 20, each dialing component 400 is located at the front end of the lifting rail 300. The distance from the lower end of the dialing component 400 to the upper surface of the conveyor chain 20 is less than the outer diameter of the first one-way sprocket 211.

[0058] Specifically, after the first copper insertion state of the cathode mounting mechanism 100 ends, there may be a situation where the first one-way sprocket 211 falls but does not fully engage with the conveyor chain 20. In this case, there is a risk that the second one-way sprocket 221 will rotate, that is, there is a risk that the relative position of the cathode mounting mechanism 100 will change. To avoid this situation, in this embodiment, a dialing element 400 is provided; since the distance from the lower end of the dialing element 400 to the upper surface of the conveyor chain 20 is less than the outer diameter of the first one-way sprocket 211, after the first copper insertion state of the cathode mounting mechanism 100 ends and the first one-way sprocket 211 falls, with the continuous movement of the conveyor chain 20, the dialing element 400 can move the first one-way sprocket 211 clockwise, such as... Figure 5 As shown, the first one-way sprocket 211 rotates clockwise to fully engage with the conveyor chain 20. The specific structure of the dial switch 400 can be adapted to be plate-shaped, rod-shaped, tubular, etc., according to actual needs. In this embodiment, the specific structure of the dial switch 400 is not specifically limited.

[0059] Furthermore, during the clockwise rotation of the first one-way sprocket 211 by the dialing component 400, to prevent the lower end of the dialing component 400 from interfering with the first one-way sprocket 211 and causing damage to it, in this embodiment, the lower end surface of the dialing component 400 is set as an inclined auxiliary surface, which is inclined downwards along the conveying direction of the conveying chain 20; alternatively, the lower end surface of the dialing component 400 is provided with a flexible actuating part. The material of the flexible actuating part can be adapted to actual needs, such as rubber, silicone, or silicone rubber, and is not specifically limited in this embodiment.

[0060] Furthermore, each lifting rail 300 has two end faces in the conveying direction of the conveying chain 20 configured as auxiliary lifting surfaces. From both ends of the lifting rail 300 to the middle of the corresponding lifting rail 300, both auxiliary lifting surfaces are inclined upwards. This configuration improves the convenience and smoothness of the lifting auxiliary roller 212 rolling to or from the upper end face of the lifting rail 300, thereby ensuring the smoothness and continuity of the cathode mounting mechanism 100's conveying process.

[0061] Regarding the connection method of the first limiting component 210 being movably disposed in the cathode mounting mechanism 100, this embodiment provides two implementation methods, specifically:

[0062] In the first type, the first limiting component 210 further includes a first mounting member 214, a first fixing seat 215, and a first connecting shaft 216; a first one-way bearing 213 is disposed at the first end of the first mounting member 214, and the second end of the first mounting member 214 is rotatably connected to the first fixing seat 215 through the first connecting shaft 216. The first fixing seat 215 is disposed on the cathode mounting mechanism 100.

[0063] Combination Figure 7 and Figure 8 As shown, by setting a first one-way bearing 213, the first one-way sprocket 211 can rotate clockwise; by setting a first connecting shaft 216, the first one-way sprocket 211 can rotate relative to the first connecting seat, i.e., the cathode mounting mechanism 100; by setting a first mounting member 214, clearance space is provided for the rotation of the first one-way sprocket 211 relative to the first connecting seat, i.e., the cathode mounting mechanism 100. When the auxiliary roller 212 is located on the upper surface of the corresponding lifting rail 300, the first mounting member 214 and the first one-way bearing 213 rotate upward relative to the first connecting seat; when the auxiliary roller 212 falls from the upper surface of the corresponding lifting rail 300, the first mounting member 214 and the first one-way bearing 213 rotate downward relative to the first connecting seat.

[0064] Furthermore, the first limiting component 210 also includes a first torsion spring 217, which is sleeved on the first connecting shaft 216. The two first torque shafts of the first torsion spring 217 abut against the first mounting member 214 and the first fixed seat 215, respectively. When the first mounting member 214 and the first one-way bearing 213 rotate upward relative to the first connecting seat, the first torsion spring 217 is compressed. When the auxiliary roller 212 falls from the upper end face of the corresponding lifting track 300, the external force on the first torsion spring 217 decreases, and it begins to return to its original state. At this time, the first torsion spring 217 pushes the first mounting member 214 to rotate downward relative to the first connecting seat. Under the action of the thrust of the first torsion spring 217 and the gravity of the first mounting member 214, the first one-way sprocket 211, and the auxiliary roller 212, the first one-way sprocket 211 can be fully engaged with the conveyor chain 20.

[0065] The second type includes a first mounting member 214 and a first fixing seat 215 in the first limiting component 210; a first one-way bearing 213 is disposed at the first end of the first mounting member 214, and a slider (not shown in the figure) is disposed at the second end of the first mounting member 214; the first fixing seat 215 is disposed on the cathode mounting mechanism 100, and a sliding groove (not shown in the figure) extending in the vertical direction is disposed on the side of the first fixing seat 215 away from the cathode mounting mechanism 100, and the slider slides in cooperation with the sliding groove.

[0066] By setting the first one-way bearing 213, the first one-way sprocket 211 can rotate clockwise; by setting the first connecting shaft 216, the first one-way sprocket 211 can move vertically relative to the first connecting seat, i.e., the cathode mounting mechanism 100. When the auxiliary roller 212 is located on the upper surface of the corresponding lifting track 300, the slider slides upward in the groove; when the auxiliary roller 212 falls from the upper surface of the corresponding lifting track 300, the slider slides downward in the groove.

[0067] Furthermore, the first limiting component 210 also includes a compression spring (not shown in the figure) and a tension spring (not shown in the figure). The upper end of the first fixed seat 215 is provided with a first auxiliary part, and the lower end is provided with a second auxiliary part. Both the first auxiliary part and the second auxiliary part extend towards the first mounting member 214. The upper end of the compression spring is connected to the first auxiliary part, and the lower end is fixedly connected to the upper end face of the first mounting member 214. When the auxiliary roller 212 is located on the upper end face of the corresponding lifting rail 300, the compression spring is compressed. When the auxiliary roller 212 falls from the upper end face of the corresponding lifting rail 300, the external force on the compression spring decreases, and it begins to return to its original state. At this time, the compression spring pushes the first mounting member 214 to slide downward relative to the first connecting seat. Under the pushing force of the compression spring and the gravity of the first mounting member 214, the first one-way sprocket 211, and the auxiliary roller 212, the first one-way sprocket 211 can be fully engaged with the conveyor chain 20. Similarly, the upper end of the tension spring is connected to the lower end face of the first mounting member 214, and the lower end is connected to the second auxiliary part. When the auxiliary roller 212 is located on the upper end face of the corresponding lifting rail 300, the tension spring is stretched; when the auxiliary roller 212 falls from the upper end face of the corresponding lifting rail 300, the external force on the tension spring decreases, and it begins to return to its original state. At this time, the tension spring pulls the first mounting member 214 to slide downward relative to the first connecting seat. Under the action of the tension of the tension spring and the gravity of the first mounting member 214, the first one-way sprocket 211, and the auxiliary roller 212, the first one-way sprocket 211 can be fully engaged with the conveyor chain 20. The compression spring and the tension spring can be selected or set simultaneously; no specific limitation is made in this embodiment.

[0068] Furthermore, the second limiting assembly 220 also includes a second one-way bearing 222, a second mounting member 223, a second fixed seat 224, a second connecting shaft 225, and a second torsion spring 226; the second one-way sprocket 221 is rotatably connected to the first end of the second mounting member 223 via the second one-way bearing 222, the second section of the second mounting member 223 is rotatably connected to the second fixed seat 224 via the second connecting shaft 225, the second fixed seat 224 is connected to the cathode mounting mechanism 100, the second torsion spring 226 is sleeved on the second connecting shaft 225, and the two second torque shafts of the second torsion spring 226 respectively abut against the second mounting member 223 and the second fixed seat 224. By setting a second one-way bearing 222, the second one-way sprocket 221 can rotate counterclockwise; by setting a second connecting shaft 225, the second one-way sprocket 221 can rotate relative to the second connecting seat, i.e., the cathode mounting mechanism 100; by setting a second mounting member 223, clearance space is provided for the rotation of the second one-way sprocket 221 relative to the second connecting seat, i.e., the cathode mounting mechanism 100. With this configuration, during the movement of the conveyor chain 20, when the emergency mounting mechanism vibrates, the second one-way sprocket 221 can move vertically, achieving a certain buffering effect and preventing damage to the second one-way sprocket 221 or breakage of the conveyor chain 20 due to direct rigid contact. During the vertical movement of the second one-way sprocket 221, the second torsion spring 226 can promptly engage the second connecting member and the second one-way sprocket 221 with the conveyor sprocket, thereby ensuring the limiting effect on the cathode mounting mechanism 100.
