Description

Water seal conductive clip

This new creation is about a processing equipment, and especially about a water-sealed conductive clip.

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 of manufactured products and their output, often unable to take into account.

In terms of the electroplating of the PCB process, as the required contact area of the workpiece (that is, the product target) is as large as possible, the current method is to increase the clamping area of the object to be plated, and to have good plating The liquid barrier effect causes waste of the edge material of the product target. Under actual mass production, it is found that if the clamping arm enters the plating solution, if the plating solution comes into contact with the bumps, it will cause the bumps to be more or less plated with residual copper, resulting in poor quality. When it reaches a certain level, It must be manually removed by chemical liquid cleaning (reverse plating) to remove residual copper, in addition to increasing pollution will also increase costs.

In addition to electroplating technology, all equipment that requires conductive clips will also encounter the above-mentioned technical problems.

The novel creation provides a water-sealed conductive clip, which can avoid or reduce the increase of pollution and the increase of cost, in addition to reducing the waste of the edge material of the product target.

The water-sealed conductive clip created by the novel includes at least a first clip arm, a second clip arm, a first soft seal, a second soft seal, a liquid supply assembly, and several hard protective sleeves. The opposite side surfaces of the first and second clamping arms respectively have first and second protrusions corresponding to the positions of the clamping surfaces. Moreover, the first clamp arm also has an opening disposed above the first protrusion and penetrating the first clamp arm. When the first clamping arm clamps a workpiece, the contact area between the first projection and the workpiece is smaller than the clamping surface of the first projection. When the second clamping arm clamps the workpiece, the contact area of the second projection and the workpiece is smaller than the clamping surface of the second projection. The liquid supply assembly communicates with the opening in the first clamp arm, and in the past, the space between the first clamp arm and the second clamp arm was used to deliver liquid. The first soft seal has a first opening with a position corresponding to the first bump and the opening, and a plurality of first idle openings on both sides of the first opening, wherein the first opening covers the first The periphery of the bump communicates with the opening, and each of the first idle openings is disposed on the side of the first bump. The second soft seal has a second opening with a position corresponding to the second protrusion and a plurality of second idle openings respectively 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 disposed on the side of the second bump. The hard protective sleeve covers the surfaces of the first and second clamping arms.

In an embodiment of the 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 communicates with the opening of the first clamp arm and has an opening. The liquid line is connected to the opening.

In an embodiment of the invention, the liquid supply assembly may only include a liquid line connected to the opening of the first clamp arm.

In an embodiment of the invention, the liquid is water.

In an embodiment of the invention, the width of the clamping surface of the first bump is greater than half of the width of the first clamping arm.

In an embodiment of the present invention, the width of the portion where the second protrusion is provided on the second clip arm is greater than the width of the remaining portions.

In an embodiment of the invention, the contact area between the first bump and the workpiece is equal to or less than half, 1/3, or 2/3 of the clamping surface of the first bump.

In an embodiment of the invention, the contact area between the second bump and the workpiece is equal to or less than half, 1/3, or 2/3 of the clamping surface of the second bump.

In an embodiment of the invention, the number of the first idle openings is more than 2.

In an embodiment of the invention, the number of the second idle openings is more than 2.

Based on the above, this new creation uses a sealing structure with a specific structural design and a liquid supply assembly to enable the object to be plated to be completely sandwiched with the bump, unlike the past, even if there is no object to be plated on the upper half of the bump The upper part of the soft seal can be closely matched by the asymmetric design of the upper part of the soft seal, and the liquid supply assembly can transport the liquid to the space where there is no object to be plated on the upper half of the bump during the entire process , So that the pressure in the space is equal to or slightly greater than the external pressure, so it can block the leakage of the chemical solution or other processing solution from the top or side to the bump clamping surface as the electrode, resulting in the bumps also coated with residual copper to affect the quality It is even necessary to manually remove the residual copper by chemical liquid cleaning (reverse plating) to increase the problem of pollution and cost. Moreover, soft seals (such as rubber) may also be coated with residual copper, so the idle openings designed on both sides of the bump can provide several soft spaces so that the infiltrating conductive liquid will not directly penetrate into the conductive bump In addition to protecting the bumps, the soft parts of the inner ring of the bumps can also be protected.

FIG. 1 is a schematic perspective view of a water-sealed conductive clip according to a first embodiment of the invention.

Referring to FIG. 1, the water-sealed conductive clip 100 in the embodiment at least includes a first clip arm 102, a second clip arm 104, a first soft seal 106, a second soft seal 108, a hard protective sleeve 110 and a liquid supply assembly 112. "Soft" and "hard" are relative terms in the text; in detail, soft is a deformable material, hard is an indeformable material, or a material with a lower amount of deformation than soft.

Please refer to FIGS. 2 and 3 for the detailed structure of the first clamp arm 102. FIG. 2 is a partially enlarged view of the first clamp arm 102 of FIG. 1, and FIG. 3 is a longitudinal half-cut schematic diagram of FIG.

2 and 3, a side surface 102a of the first clamping arm 102 has a first protrusion 114, the first protrusion 114 has a clamping surface 114a and a side surface 114b, wherein the clamping surface 114a refers to clamping the workpiece (not shown) And the first bump 114 is a part of the first clamp arm 102, so the material is the same as the first clamp arm 102, such as stainless steel or other conductive materials. The first clamping arm 102 further has an opening 116 passing through the first clamping arm 102 above the first protrusion 114. The liquid supply assembly 112 is connected to the opening 116 in the first clamp arm 102. In the past, the space between the first clamp arm 102 and the second clamp arm conveyed liquid, and the liquid such as water or other would not corrode the first clamp arm 102 (with the first bump 114) liquid. In this embodiment, the liquid supply assembly 112 may include a liquid storage tank 118 and a liquid line (not shown), wherein the liquid storage tank 118 is formed on the other side 102b of the first clamping arm 102 and the liquid is stored The groove 118 communicates with the opening 116 and has an opening (118a in FIG. 1). The remaining detailed structure will be described below. However, the creation of the present invention is not limited to this, any structure that can deliver liquid to the space between the first clamp arm 102 and the second clamp arm can be used as the liquid supply assembly 112. The first soft seal 106 has a first opening 106a corresponding to the first bump 114 and the opening 116, and first idle openings 106b located on both sides of the first opening 106a, wherein the first opening 106a is covered The periphery of the first bump 114 communicates with the opening 116, and each of the first idle openings 106b is provided on the side 114b of the first bump 114 to prevent the chemical liquid or other treatment solution from directly infiltrating into the conductive surface from the side In addition to protecting the first bump 114, the first bump 114 may also protect the soft part of the first opening 106a. In this embodiment, the number of first idle openings 106b is two, but the creation of the novel is not limited to this, the number of first idle openings 106b may also be more than two, for example, two on each side of the first opening 106a There are four first idle openings 106b, so there are four first idle openings 106b, and so on.

The clamping surface 114a of the first bump 114 is slightly retracted into the first opening 106a, so that when the water-sealing conductive clip 100 clamps the workpiece, the first and second soft seals 106 and 108 can tightly seal the first bump 114 and the second bump. At the same time, the first idle opening 106b has a space to accommodate the infiltrated chemical solution or other treatment solution. In the present embodiment, the hard protective cover 110 covers the surface of the first clamping arm 102 close to the first bump 114, but the creation of the present invention is not limited to this, the hard protective cover 110 can also extend to the first of FIG. 1 With the upper half of the second clamp 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.

Although FIGS. 2 and 3 are the first clamping arm 102, it should be understood that the structure of the second clamping arm 104 basically corresponds to the first clamping arm 102, but does not include the opening 116 and the liquid supply assembly 112, please see the figure 4. For example, the side 104a of the second clamping arm 104 and the first clamping arm 102 has a second protrusion 120, the second protrusion 120 has a clamping surface 120a and a side 120b, and the position of the clamping surface 120a of the second protrusion 120 corresponds to the first At the position of the clamping surface 114a of a projection 114, the second projection 120 is a part of the second clamping arm 104, so its material is the same as the second clamping 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 bump 120 and second idle openings (not shown) located on both sides of the second opening 108a, wherein the second opening 108a covers the second The periphery of the bump 120, and each second idle opening is provided on the side of the second bump 120 to prevent the chemical liquid or other processing solution from directly infiltrating into the conductive second bump 120 from the side, in addition to protecting the second Outside the bump 120, the soft part of the second opening 108a may also be protected. Similarly, the number of second idle openings is two, but the creation of the present invention is not limited to this, the number of second idle openings can also be more than two, for example, there are two second idle openings on each side of the second opening 108a , So there are a total of 4 second idle openings, and so on. The hard protective cover 110 covers the surfaces of the first and second clamping arms 102 and 104.

In this embodiment, when the first and second clamping arms 102 and 104 clamp the workpiece 122, the workpiece 122 (to-be-plated) does not need to completely clamp the first and second bumps 114 and 120 (such as the first The contact area of a bump 114 and the workpiece 122 is smaller than the clamping surface 114a of the first bump 114, and the contact area of the second bump 120 and the workpiece 122 is smaller than the clamping surface 120a of the second bump 120), so the first and second The upper parts of the bumps 114 and 120 are not clamped by the workpiece 122. For example, the contact area between the first bump 114 and the workpiece 122 may be equal to or smaller than half, 1/3, or 2/3 of the clamping surface 114a of the first bump 114, but the invention is not limited thereto. Similarly, the contact area between the second bump 120 and the workpiece 122 is, for example, equal to or less than half, 1/3, or 2/3 of the clamping surface 120a of the second bump 120, but the creation of the present invention is not limited thereto. Once the workpiece 122 is clamped, the portions of the first and second clamping arms 102 and 104 that are in contact with the workpiece 122 (ie, the first and second bumps 114/120) will closely adhere to the workpiece 122, and the first and second The first and second soft seals 106/108 above the bumps 114/120 will stick to each other and seal the upper edge of the workpiece 120, showing an asymmetrical appearance. According to the past fixture, if clamped in this way, chemical liquid or other treatment solution will enter this space. However, the present invention creates an asymmetrical design on the upper parts of the first and second soft seals 106 and 108, so that the upper soft seals (106 and 108) can be closely fitted, and the liquid supply assembly 112 is used during the entire process The liquid 124 such as water is continuously or intermittently delivered to the space 124 without the workpiece 120, so that the pressure (water pressure) in the space 124 is equal to or slightly greater than the external pressure, so the problem of the entry of the above-mentioned chemical liquid (or other processing solution) can be solved. To achieve the function of blocking the entry of the chemical liquid through the upper side, the first and second protrusions 114/120 have first and second idle openings on the sides to achieve the function of temporarily infiltrating the chemical liquid, so it can effectively prevent the first One with the second bumps 114 and 120 long copper.

In order to explain the exemplary structure and operation of the liquid supply assembly of the first embodiment, please refer to FIG. 5.

5 is the first and second clamp arms 102 and 104 of FIG. 1 opened, and the liquid line 126 of the liquid supply assembly 112 is connected to the opening 118a of the liquid storage tank 118, and the liquid line 126 can be connected to The container 128 is added, so the liquid in the container 128 can be transported between the first and second clamping arms 102 and 104 via the liquid supply assembly 112. Once the water-seal conductive clamp 100 clamps the workpiece, the liquid will naturally flow into the space between the first clamp arm 102 and the second clamp arm 104, so that the water pressure there is close to or slightly greater than the external water pressure. In addition, the water-sealed conductive clip 100 of FIG. 5 may further be provided with a transfer bar 130 and two movable brackets 132a and 132b connecting the first and second clip arms 102 and 104 to the transfer bar 130. However, the creation of the present invention is not limited to this, and other components connected to the first and second clip arms 102 and 104 in the water-sealed conductive clip 100 may also adopt other designs.

6 is a schematic cross-sectional view of a water-sealed conductive clamp clamping a workpiece according to a second embodiment of the present invention, in which the same element symbols as in FIG. 4 are used to denote the same or similar components, and the same or similar components are also Reference may be made to the first embodiment, and no further description will be given.

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 line 602 connected to the opening 116, It can be directly connected to a container that will have liquid (128 in Figure 5). The liquid supply assembly 600 can also inject liquid into the space 124 between the first clamp arm 102 and the second clamp arm 104, so that the pressure in the space 124 is equal to or slightly greater than the external pressure, so it can achieve the function of blocking the entry of the liquid through the upper side. Therefore, the first and second bumps 114 and 120 can be effectively prevented from growing copper.

To sum up, the new creation does not need to completely clamp the bump as traditional, so the upper half of the bump is not clamped by the plating. According to the past clamp, if the workpiece is clamped in this way, the liquid will enter, and In order to solve the above-mentioned situation, the new creation uses a liquid supply component in an asymmetric design above the soft seal, so that the upper soft part can closely fit, and the liquid supply component continues to protrude toward the entire process. The space in the upper half of the block without plating is to transport liquid, so that the pressure in the space is equal to or slightly greater than the external pressure, so it can block the entry of chemical liquid (or other processing solution), and can simultaneously reduce the edge of the workpiece (board edge) The area of the ineffective area and prevent the leakage of the chemical solution or other processing solution to the electrode bump surface, resulting in the bump will also be coated with residual copper to affect the quality, and even manual cleaning with chemical solution (reverse plating) Removal and other issues that increase pollution and cost. Moreover, the idle openings designed on both sides of the bump can provide several soft spaces, so that the infiltrating conductive liquid will not directly penetrate into the conductive bump. In addition to protecting the bump, it can also protect the softness of the inner ring of the bump section.

Although the new creation has been disclosed as above with examples, it is not intended to limit the creation of the new creation. Anyone with ordinary knowledge in the technical field of the subject can make some changes and without departing from the spirit and scope of the creation of the new creation. Retouching, so the scope of protection of this new creation shall be subject to the scope defined in the appended patent application.
