Description

Technical Field

[0001] The invention relates to the technical field of vertical electroplating, in particular to a copper rice grain structure for vertical electroplating. Background Art

[0002] Vertical electroplating is a method of electroplating in which the material to be electroplated is suspended vertically in the electroplating tank to form a metal film on the substrate through an electrolytic reaction. Vertical electroplating is widely used in PCB copper plating process and HJT battery copper electrode plating and other fields. In the PCB copper plating process, vertical electroplating can provide a uniform and dense copper layer to meet the requirements of electronic products for conductivity and mechanical properties.

[0003] In the current actual production process, vertical electroplating uses a circular copper cake structure to react with the plating solution, and simultaneously needs to provide current to the copper cake through an external titanium plate to form an electric field. Since the plating solution can only react with one side of the copper cake during the vertical electroplating process, the copper ion precipitation rate is slow, and the copper utilization efficiency in the copper cake structure is low. In addition, during the electroplating process, the elemental phosphorus and other impurities contained in the copper cake will gradually accumulate and adhere to the surface of the copper cake as the reaction proceeds. This attachment will hinder the rate of subsequent reactions and reduce the effect of product electroplating, resulting in high equipment use costs, short equipment maintenance time intervals, and high requirements for parts processing.

[0034] Two limit plates 5 are commonly arranged above the two groups of first support frames 202, and the bottom surface of each limit plate 5 is in contact with the upper surface of the second support frame 203. The limit plates 5 can limit the positions of the first clamping block 207 and the second clamping block 209 inside the first support frame 202, so as to achieve the purpose of fixed limit and prevent the position from shaking and shifting during use;

[0035] The inner wall of each limiting plate 5 is threadedly connected with two limiting bolts 6, and the outer surface of each set of limiting bolts 6 is threadedly connected with the inner wall of the first support frame 202. The limiting bolts 6 can reinforce the limiting plate 5 and the first support frame 202 to enhance the stability of the device;

[0036] Two fixing blocks 7 are fixedly connected to the outer surface of the filter plate 206, and the side surfaces of the two fixing blocks 7 that are away from each other are fixedly connected to the inner wall of the second support frame 203. The filter plate 206 and the second support frame 203 can be fixed by the fixing blocks 7, which has a strong reinforcement effect and effectively avoids the problem of shaking during use.

[0037] The specific implementation of this embodiment is as follows: first, fill the inside of titanium blue 210 with copper particles, and then install it in the second card block 209 to make it act as a soluble anode consumption layer. The gaps between the copper particles cause the reaction liquid to have a larger contact area with the anode, and the reaction rate of the electroplating solution is significantly improved. This can improve the process technology of the end customer and accelerate production. The larger contact area of ​​the copper particles provides the possibility of extending the maintenance time, which reduces the downtime of the client and improves the production efficiency. Then, a layer of anode mesh 213 is installed on the outside of titanium blue 210 to allow impurities generated by the filtration reaction to enter. On the coating, by installing the limit frame 211 in the second clamping block 209, a second titanium mesh 212 can be installed on the outside of the anode mesh 213 to fasten the anode mesh 213 to prevent its position from being greatly offset during use.

Finally, the inside of the perspective tube 204 is filled with copper particles for automatic replenishment setting, which prolongs the maintenance time. After each maintenance, the perspective tube 204 is filled with copper particles, and the consumption of copper particles inside the titanium blue 210 can be checked without a large-scale shutdown inspection. In this way, the copper particles can be electroplated. As a material for electroplating, copper rice particles have excellent The conductive properties can effectively conduct current during the electroplating process, so that copper ions can be smoothly deposited on the surface of the plated object under the action of the electric field to form a uniform and dense electroplated copper layer. It can effectively avoid the vertical electroplating process in which the plating solution can only react with one side of the copper cake. In addition, during the electroplating process, the elemental phosphorus and other impurities contained in the copper cake will gradually accumulate and adhere to the surface of the copper cake as the reaction proceeds. Such attachments will hinder the rate of subsequent reactions and reduce the effect of product electroplating, resulting in high equipment use costs, short equipment maintenance time intervals, and high requirements for parts processing.
