DETAILED DESCRIPTION

[0034] Some embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the scope of protection of the present application.

[0035] When the anode is used to electroplate the packaging substrate, the anode current is consistent. However, due to various factors such as chemical agents, agent stirring, and packaging substrate material, multiple electroplating areas of different thicknesses are often generated on the electroplating surface of the substrate, which in turn affects the product quality.

[0036] Based on this, this application provides a partitioned anode mechanism, which enables separate control of all electroplating areas by setting corresponding anode structures in different electroplating areas for electroplating, thereby improving the thickness consistency of all electroplating areas and enhancing product quality.

[0037] The present application will be described in detail below through specific embodiments.

[0038] Reference Figures 1 to 4 As shown, this embodiment provides a partitioned anode mechanism, including: a partitioned main board 1, an isolator 2, at least two anode structures, and at least two conductive elements corresponding one-to-one with the anode structures; at least two anode structures are arranged on a first surface of the partitioned main board 1, which may be the surface of the partitioned main board 1 facing the substrate 4. The projection range of the same anode structure on the first surface corresponds to the same electroplating area on the substrate 4. The same electroplating area of ​​the substrate 4 refers to the fact that after electroplating, the surface of the traditional substrate 4 will form multiple areas of different thicknesses. Electroplating areas of the same thickness are the same electroplating area. Each pair of adjacent anode structures is separated by the isolator 2 to achieve insulation between them. The anode structures are electrically connected to an external power source through the corresponding conductive elements; the partitioned main board 1 is used to connect the substrate 4.

[0039] The partitioned anode mechanism provided in this embodiment enables separate control of all electroplating areas by setting corresponding anode structures in different electroplating areas, thereby improving the thickness consistency of all electroplating areas and enhancing product quality.

[0040] In some embodiments, at least two anode structures have the same resistance. Further, at least two anode structures may have the same projected area on the first surface, the same thickness in the direction perpendicular to the first surface, and the same material. When the anode structure is a mesh structure, it is also necessary to ensure that the arrangement of the perforations and the size of the perforations are the same. All anode structures may be metal mesh structures of the same thickness formed by cutting them into a set shape. Specifically, the metal mesh structure may be an iridium-titanium mesh structure.

[0041] Based on the aforementioned partitioned anode mechanism, the thickness of all electroplating areas can be precisely controlled simply by adjusting the current or voltage of the external power supply for different anode structures, thereby further improving the thickness consistency of all electroplating areas.

[0042] In further some embodiments, the at least two conductive members are respectively connected with two external power sources, wherein the two external power sources refer to power sources with different output currents or voltages, or the same power source with different output currents or voltages, that is, two anode structures with the same resistance need to be respectively connected with power sources with different output currents or voltages, so as to realize the unification of the electroplated layers with different thicknesses into the same thickness.

[0043] In some embodiments, the first surface is parallel to the electroplating surface of the substrate 4, and the anode structure is located in the gap between the first surface and the electroplating surface, and the anode structure can be a plate structure as a whole, and the inner and outer surfaces are respectively attached to the first surface and the electroplating surface.

[0044] Based on the above-mentioned partitioned anode structure, the anode structure is attached to the electroplating surface, thereby improving the electroplating efficiency and electroplating effect, and reducing the interference of other factors from the outside.

[0045] Referring back to Figures 1 to 3 As shown, the partitioned main plate 1 is provided with a fixing frame 11, and the at least one conductive member is connected with the fixing frame 11.

[0046] Based on the above-mentioned fixing frame 11, the conductive member connected with the anode structure can be fixed, thereby improving the integrity of the entire partitioned anode structure and reducing the influence of the instability of the conductive member on the electroplating process.

[0047] In some embodiments, the fixing frame 11 is provided with at least two fixing structures 111 at intervals, and the fixing structure 111 is used to fix one of the conductive members, specifically, the number of the fixing structures 111 on the fixing frame 11 is the same as the number of the conductive members, that is, the number of the fixing structures 111, the conductive members and the anode structure is the same.

[0048] Based on the above-mentioned fixing frame 11, all the conductive members can be fixed on the same side of the partitioned main plate 1, which facilitates the arrangement of the external power source and also enables the fixation of all the conductive members.

[0049] Referring back to Figures 1 to 4 As shown, the partitioned main plate 1 is further provided with a connecting portion 12, and the connecting portion 12 is detachably connected with the substrate 4.

[0050] Based on the above-mentioned connecting portion 12, the connection and separation of the partitioned main plate 1 and the substrate 4 can be facilitated, and the connection can be achieved through bolts, buckles or the like, wherein the connecting portion 12 can have an attaching surface with the substrate 4, thereby ensuring the connection reliability of the partitioned main plate 1 and the substrate 4.

[0051] In some embodiments, at least two anode structures are arranged in a U-shape on the first surface of the partition motherboard 1, and the spacer 2 is an annular structure and is sleeved between two adjacent anode structures. One anode structure may be a square or circular structure, and the other anode structure may be an annular structure sleeved outside the square anode structure. Alternatively, one annular anode structure may be sleeved outside the other annular anode structure.

[0052] Based on the above anode structure and the isolation element 2, the insulation effect of the isolation element 2 can be improved, and the presence of ends or gaps can be avoided, which would affect the electroplating effect between two adjacent anode structures.

[0053] Continue to refer to Figure 1 and Figure 2 As shown, there are three anode structures: a first anode structure 31, a second anode structure 32, and a third anode structure 33.

The second anode structure 32 is a ring structure and is fitted around the outer periphery of the first anode structure 31. The third anode structure 33 is a ring structure and is fitted around the outer periphery of the second anode structure 32. It should be understood that the number of anode structures can also be four or more, as long as they are fitted together sequentially according to the electroplating areas on the substrate 4.

[0054] Based on the above anode structure, the anode structure can be accurately arranged according to the electroplating area on the substrate 4, thereby further improving the electroplating effect on the substrate 4 and further improving the thickness consistency of different electroplating areas on the electroplating surface of the substrate 4.

[0055] Optionally, the anode structure located at the inner side has a connecting point on the surface facing away from the substrate 4 connected with the conductive piece; the anode structure located at the outermost side has a connecting point on the surface facing away from the substrate 4 connected with the conductive piece, or the anode structure located at the outermost side has a connecting point on the circumferential side connected with the conductive piece; wherein, when the number of the anode structures and the conductive pieces are both three, the three anode structures are the first anode structure 31, the second anode structure 32 and the third anode structure 33, the three conductive pieces are the first conductive piece 51, the second conductive piece 52 and the third conductive piece 53, the three anode structures are sequentially sleeved from inside to outside, the first anode structure 31 located at the innermost side is a square or circular plate structure, one end of the first conductive piece 51 is connected with the surface of the first anode structure 31 facing away from the substrate 4, and specifically can be connected with any point of the outer frame or the central area of the first anode structure 31, the middle part of the first conductive piece 51 can be connected with the fixed structure 111, and the other end of the first conductive piece 51 is connected with an external power supply; one end of the second conductive piece 52 is connected with the surface of the second anode structure 32 facing away from the substrate 4, and specifically can be connected with any point of the outer frame or the central area of the second anode structure 32, the middle part of the second conductive piece 52 can be connected with the fixed structure 111, and the other end of the second conductive piece 52 is connected with an external power supply; one end of the third conductive piece 53 is connected with the surface of the third anode structure 33 facing away from the substrate 4, and specifically can be connected with any point of the outer frame or the central area of the third anode structure 33, the middle part of the third conductive piece 53 can be connected with the fixed structure 111, and the other end of the third conductive piece 53 is connected with an external power supply.

[0056] Further, the first conductive piece 51 can be connected with the frame of the first anode structure 31 close to the fixed structure 111, the second conductive piece 52 can be connected with the frame of the second anode structure 32 close to the fixed structure 111, and the third conductive piece 53 can be connected with the frame of the third anode structure 33 close to the fixed structure 111, based on the above conductive pieces, the length and volume of the conductive pieces can be reduced, the stability of the whole can be improved, and the space occupation can be reduced, facilitating arrangement.
