Description

Technical Field

[0001] The invention relates to a processing device, in particular to a water-sealed conductive clip. Background Art

[0002] In the printed circuit board (PCB) or other related industries, the development of electroplating technology continues to evolve with the needs of users, especially for the quality and output of manufactured products, which are often not taken into account at the same time.

[0003] In terms of electroplating in PCB technology, the larger the contact area of ​​the clamping point of the required workpiece (i.e., the target product), the better. Therefore, the current method is to increase the clamping area of ​​the plated object and have a good barrier effect of the plating solution, resulting in waste of edge material of the target product. At present, it is found in actual mass production that if the clamp arm enters the plating solution and the plating solution comes into contact with the bump, the bump will be plated with more or less residual copper, resulting in poor quality. When it reaches a certain level, the residual copper must be removed manually by chemical liquid cleaning (reverse plating method), which will increase pollution and cost.

[0004] In addition to electroplating technology, any equipment that requires conductive clips will also encounter the above technical problems. Summary of the invention

[0005] The present invention provides a water-sealed conductive clip, which can not only reduce the waste of edge line materials of product targets, but also avoid or reduce the increase of pollution and the increase of cost.

[0006] The water-sealed conductive clamp of the present invention comprises at least a first clamp arm, a second clamp arm, a first soft seal, a second soft seal, a liquid supply assembly and several hard protective covers. The facing sides of the first and second clamp arms respectively have first and second protrusions corresponding to the positions of the clamping surfaces. Moreover, the first clamp arm also has an opening arranged above the first protrusion and penetrating the first clamp arm. When the first clamp arm clamps a workpiece, the contact area between the first protrusion and the workpiece is smaller than the clamping surface of the first protrusion. When the second clamp arm clamps the workpiece, the contact area between the second protrusion and the workpiece is smaller than the clamping surface of the second protrusion. The liquid supply assembly is connected to the opening in the first clamp arm, and the space between the first clamp arm and the second clamp arm is infused. The first soft seal has a first opening whose position matches that of the first protrusion and the opening, and several first idle openings respectively located on both sides of the first opening, wherein the first opening covers the periphery of the first protrusion and is connected to the opening, and each of the first idle openings is arranged on the side of the first protrusion. The second soft seal has a second opening corresponding to the second protrusion and a plurality of second idle openings located on both sides of the second opening, wherein the second opening covers the periphery of the second protrusion, and each of the second idle openings is arranged on the side of the second protrusion. The hard protective cover covers the surface of the first and second clamp arms.

[0007] In one embodiment of the present invention, the liquid supply assembly includes a liquid storage tank and a liquid pipeline. The liquid storage tank is disposed on the other side of the first clamp arm, and the liquid storage tank is connected to the opening of the first clamp arm and has an opening. The liquid pipeline is connected to the opening.

[0008] In one embodiment of the present invention, the liquid supply assembly may only include a liquid pipeline connected to the opening of the first clamping arm.

[0009] In one embodiment of the present invention, the liquid is, for example, water.

[0010] In an embodiment of the present invention, the width of the clamping surface of the first protrusion is greater than or equal to half of the width of the first clamping arm.

[0011] In one embodiment of the present invention, the width of the clamping surface of the second protrusion is greater than or equal to half of the width of the second clamping arm.

[0012] In one embodiment of the present invention, the width of the portion of the first clamping arm where the first protrusion is disposed is greater than the width of the remaining portions.

[0013] In one embodiment of the present invention, the width of the portion of the second clamping arm where the second protrusion is disposed is greater than the width of the remaining portion.

[0014] In one embodiment of the present invention, the contact area between the first protrusion and the workpiece is equal to or less than half, 1 / 3 or 2 / 3 of the clamping surface of the first protrusion.

[0015] In one embodiment of the present invention, the contact area between the second protrusion and the workpiece is equal to or less than half, 1 / 3 or 2 / 3 of the clamping surface of the second protrusion.

[0016] In one embodiment of the present invention, the number of the first idle openings is greater than 2.

[0017] In one embodiment of the present invention, the number of the second idle openings is greater than 2.

[0018] Based on the above, the present invention uses a sealing component with a specific structural design and a liquid supply component. In the case where the plated object does not need to be completely clamped against the bump as in the past, even if the upper half of the bump does not clamp the plated object, the part above the soft seal can still be tightly fitted through the asymmetric design above the soft seal, and the liquid is transported to the space without the plated object in the upper half of the bump during the entire treatment period through the liquid supply component, so that the pressure in the space is equal to or slightly greater than the external pressure, thereby preventing the liquid or other processing solution from leaking from the top or side to the bump clamping surface as an electrode, causing the bump to be plated with residual copper, affecting the quality, and even requiring manual cleaning with chemical liquid (reverse electroplating method) to remove the residual copper, etc., which increases pollution and cost. Moreover, soft seals (such as rubber) may also be plated with residual copper, so the idle openings designed on both sides of the bump can provide several soft spaces, so that the infiltrated conductive liquid will not directly penetrate into the conductive bump, in addition to protecting the bump, it can also protect the soft part of the inner circle of the bump.

Of course, these embodiments are only examples and are not intended to limit the scope and application of the present invention. Furthermore, for the sake of clarity, the relative thickness and position of each component, film layer or region may be reduced or enlarged. In addition, similar or identical element symbols are used in each of the drawings to indicate similar or identical elements or features, and if there is an element symbol in the drawing that is the same as the previous figure, its redundant description will be omitted.

[0051] Figure 1 It is a three-dimensional schematic diagram of a water-sealed conductive clip when it is opened according to the first embodiment of the present invention.

[0052] Please refer to Figure 1 The water seal conductive clip 100 in the embodiment at least comprises a first clamp arm 102, a second clamp arm 104, a first soft seal 106, a second soft seal 108, a hard protective cover 110 and a liquid supply assembly 112. "Soft" and "hard" in this article are relative terms; in detail, soft is a deformable material, and hard is a non-deformable material or a material with a lower deformation amount than soft.

[0053] For detailed structure of the first clamp arm 102, please refer to Figure 2 and Figure 3 , Figure 2 yes Figure 1 A partially enlarged view of the first clamping arm 102, Figure 3 yes Figure 2 Schematic diagram of the longitudinal half section.

[0054] Please refer to Figure 2 and Figure 3 , a side surface 102a of the first clamp arm 102 has a first protrusion 114, and the first protrusion 114 has a clamping surface 114a and a side surface 114b, wherein the clamping surface 114a refers to the surface for clamping a workpiece (not shown), and the first protrusion 114 is a part of the first clamp arm 102, so its material is the same as that of the first clamp arm 102, such as stainless steel or other conductive materials. The first clamp arm 102 also has an opening 116 passing through the first clamp arm 102 above the first protrusion 114. The liquid supply component 112 is connected to the opening 116 in the first clamp arm 102, and the space between the first clamp arm 102 and the second clamp arm is used to transport liquid, such as water or other liquids that will not corrode the first clamp arm 102 (and the first protrusion 114). In this embodiment, the liquid supply assembly 112 may include a liquid storage tank 118 and a liquid pipeline (not shown), wherein the liquid storage tank 118 is formed on the other side surface 102b of the first clamping arm 102, and the liquid storage tank 118 is connected to the opening 116 and has an opening portion ( Figure 1118a), and the rest of the detailed structure will be described below. However, the present invention is not limited to this, and any structure that can transport liquid to the space between the first clamping arm 102 and the second clamping arm can be used as the liquid supply component 112. The first soft seal 106 has a first opening 106a whose position matches the first protrusion 114 and the opening 116, and first idle openings 106b located on both sides of the first opening 106a, wherein the first opening 106a covers the periphery of the first protrusion 114 and is connected to the opening 116, and each first idle opening 106b is arranged on the side 114b of the first protrusion 114 to prevent the liquid or other processing solution from directly penetrating into the conductive first protrusion 114 from the side, in addition to protecting the first protrusion 114, it can also protect the soft part of the first opening 106a. In this embodiment, the number of the first idle openings 106b is 2, but the present invention is not limited thereto, and the number of the first idle openings 106b may be greater than 2, for example, there are 2 first idle openings 106b on both sides of the first opening 106a, so there are 4 first idle openings 106b in total, and so on.

[0055] The clamping surface 114a of the first protrusion 114 is slightly retracted into the first opening 106a, so that when the water-sealed conductive clamp 100 clamps the workpiece, the first and second soft seals 106 and 108 can tightly seal the first protrusion 114 and the second protrusion. At the same time, the first idle opening 106b has space to accommodate the infiltrated liquid or other processing solution. In this embodiment, the hard protective cover 110 covers the surface of the first clamp arm 102 close to the first protrusion 114, but the present invention is not limited to this. The hard protective cover 110 can also extend all the way to the first clamp arm 102. Figure 1 The hard protective cover 110 can also cover the upper part of the first and second clamping arms 102 and 104. Moreover, the hard protective cover 110 can also integrally cover the first clamping arm 102 and the liquid storage tank 118 of the liquid supply assembly 112 to fully protect the aforementioned structure.

[0056] Although Figure 2 and Figure 3 The first clamp arm 102 is shown in FIG. 1 , but it should be noted that the structure of the second clamp arm 104 is substantially the same as that of the first clamp arm 102 , but does not include the opening 116 and the liquid supply assembly 112 . Figure 4For example, the side surface 104a of the second clamp arm 104 facing the first clamp arm 102 has a second protrusion 120, and the second protrusion 120 has a clamping surface 120a and a side surface 120b, and the position of the clamping surface 120a of the second protrusion 120 corresponds to the position of the clamping surface 114a of the first protrusion 114. The second protrusion 120 is a part of the second clamp arm 104, so its material is the same as that of the second clamp arm 104, such as stainless steel or other conductive materials. The second soft seal 108 also has a second opening 108a corresponding to the position of the second protrusion 120 and second idle openings (not shown) respectively located on both sides of the second opening 108a, wherein the second opening 108a covers the periphery of the second protrusion 120, and each second idle opening is arranged on the side of the second protrusion 120 to prevent the liquid or other processing solution from directly penetrating into the conductive second protrusion 120 from the side, in addition to protecting the second protrusion 120, it can also protect the soft part of the second opening 108a. Similarly, the number of the second idle openings is 2, but the present invention is not limited thereto, and the number of the second idle openings may be more than 2, for example, there are 2 second idle openings on both sides of the second opening 108a, so there are 4 second idle openings in total, and so on. The hard protective cover 110 covers the surfaces of the first and second clamping arms 102 and 104.

[0057] In this embodiment, when the first and second clamping arms 102 and 104 clamp the workpiece 122, the workpiece 122 (the object to be plated) does not need to be completely clamped against the first and second protrusions 114 and 120 as in the past (for example, the contact area between the first protrusion 114 and the workpiece 122 is smaller than the clamping surface 114a of the first protrusion 114, and the contact area between the second protrusion 120 and the workpiece 122 is smaller than the clamping surface 120a of the second protrusion 120), so the upper half of the first and second protrusions 114 and 120 do not clamp the workpiece 122. For example, the contact area between the first protrusion 114 and the workpiece 122 may be equal to or less than half, 1 / 3 or 2 / 3 of the clamping surface 114a of the first protrusion 114, but the present invention is not limited thereto. Similarly, the contact area between the second protrusion 120 and the workpiece 122 may be equal to or less than half, 1 / 3 or 2 / 3 of the clamping surface 120a of the second protrusion 120, for example, but the present invention is not limited thereto. Once the workpiece 122 is clamped, the parts of the first and second clamping arms 102 and 104 that are in contact with the workpiece 122 (i.e., the first and second protrusions 114 / 120) below will fit tightly against the workpiece 122, and the first and second soft seals 106 / 108 above the first and second protrusions 114 / 120 will fit against each other and seal the upper edge of the workpiece 120, presenting an asymmetrical appearance. According to the previous clamps, if clamped in this way, the liquid or other processing solution will enter this space. However, the present invention uses an asymmetrical design on the upper part of the first and second soft seals 106 and 108, so that the upper soft seals (106 and 108) can fit tightly, and through the liquid supply component 112, a liquid such as water is continuously or intermittently delivered to the space 124 without the workpiece 120 during the entire processing period, so that the pressure (water pressure) in the space 124 is equal to or slightly greater than the external pressure, thereby solving the above-mentioned problem of the liquid (or other processing solution) entering. In order to block the entry of the liquid medicine from the top, the first and second protrusions 114 / 120 have first and second idle openings on their sides to temporarily store the liquid medicine infiltrating from the sides, thereby effectively preventing the first and second protrusions 114 and 120 from growing copper.

[0058] To illustrate the exemplary structure and operation of the liquid supply assembly of the first embodiment, please refer to Figure 5 .

[0059] Figure 5 yes Figure 1The first and second clamping arms 102 and 104 are opened, and the liquid pipeline 126 of the liquid supply assembly 112 is connected to the opening 118a of the liquid storage tank 118, and the liquid pipeline 126 can be connected to the external container 128, so that the liquid in the container 128 can be transported between the first and second clamping arms 102 and 104 through the liquid supply assembly 112. Once the water-sealed conductive clamp 100 clamps the workpiece, the liquid will naturally flow into the space between the first clamping arm 102 and the second clamping arm 104, so that the water pressure there is close to or slightly greater than the external water pressure. In addition, Figure 5 The water seal conductive clamp 100 may further include a transfer rod 130 and two movable brackets 132a and 132b connecting the first and second clamp arms 102 and 104 to the transfer rod 130. However, the present invention is not limited thereto, and the remaining components of the water seal conductive clamp 100 connected to the first and second clamp arms 102 and 104 may also adopt other designs.

[0060] Figure 6 is a cross-sectional schematic diagram of a water-sealed conductive clamp clamping a workpiece according to a second embodiment of the present invention, wherein the Figure 4 The same reference numerals are used to indicate the same or similar components, and the same or similar components can also refer to the first embodiment and will not be described in detail.

[0061] Please refer to Figure 6 The difference between the second embodiment and the first embodiment is that the liquid supply assembly 600 in the second embodiment does not have a liquid storage tank, but includes a liquid pipeline 602 connected to the opening 116, which can be directly connected to a container (such as Figure 5 128). The liquid supply assembly 600 can also infuse liquid into the space 124 between the first clamping arm 102 and the second clamping arm 104, so that the pressure in the space 124 is equal to or slightly greater than the external pressure, thereby achieving the function of blocking the liquid from entering through the top, and thus effectively preventing the first and second bumps 114 and 120 from growing copper.

[0062] In summary, the present invention does not need to completely clamp the bump as in the conventional method, so the upper half of the bump does not clamp the plated object. According to the previous clamps, if the workpiece is clamped in this way, liquid will enter. In order to solve the above situation, the present invention uses an asymmetrical design to match the liquid supply component above the soft seal so that the upper soft part can fit tightly, and the liquid supply component continuously transports liquid to the space without the plated object in the upper half of the bump during the entire treatment period, so that the pressure in the space is equal to or slightly greater than the external pressure, thereby blocking the entry of the chemical solution (or other processing solution), and can simultaneously reduce the ineffective area of ​​the edge of the workpiece (board edge) and prevent the chemical solution or other processing solution from leaking to the clamping surface of the electrode bump, resulting in the bump being plated with residual copper, affecting the quality, and even requiring manual chemical cleaning (reverse electroplating) to remove the residual copper, which increases pollution and cost. Moreover, the idle openings designed on both sides of the bump can provide several soft spaces so that the infiltrated conductive liquid will not directly penetrate into the conductive bump. In addition to protecting the bump, it can also protect the soft part of the inner circle of the bump.

[0063] Although the present invention has been disclosed as above by way of embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the claims.
