Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to trivalent iron copper dissolution, and in particular to a full-automatic trivalent iron copper dissolution circulation intelligent control system. Background Art
[0002] The copper plating process is mainly divided into two types: soluble anode and insoluble anode. As the electroplating proceeds, the copper ions in the electroplating solution are continuously consumed, and the copper plating effect decreases accordingly, thus affecting the electroplating effect. Therefore, copper ions need to be supplemented in the electroplating solution. There are many ways to supplement copper ions. For example, phosphor copper balls are used as soluble anodes to supplement the copper ions in the electroplating solution by dissolving the phosphor copper balls. However, anode mud will be produced during the dissolution of the phosphor copper balls, which requires regular line shutdown for cleaning, consuming a lot of manpower and time, and has a low degree of automation.
[0003] Insoluble anodes use copper oxide powder as a supplement for electroplating copper ions. Copper oxide powder dissolves slowly, and the coating is prone to produce particles after electroplating, affecting product quality. At the same time, the powder is prone to leakage during the addition process, causing environmental pollution. In addition, the cost of converting copper into copper oxide powder is high, the process is long, and it will pollute the air environment.
[0004] Current electroplating production line Fe 3+ In the copper dissolving control, only a pump is used for circulation and delivery, and there is no real-time online monitoring. In addition, in the existing technology that can control the concentration of trivalent iron entering the copper dissolving tank, a pumping function structure or a motor is used to drive the screw rod to reciprocate to achieve liquid inlet and outlet and Fe 3+ The structure is complex and the actual control is difficult.
[0005] The copper dissolving system is the front-end process of the electroplating equipment. 2+ Concentration is critical to subsequent electroplating processes.
[0006] After massive search, it was found that the prior art publication number is CN217997399U, which discloses a trivalent iron copper dissolving circulation system, including a copper dissolving tank and a copper tank, wherein the copper tank has a cathode part and a symmetrically arranged anode part, and a first nozzle and a second nozzle are respectively arranged on both sides of the anode part, and a filter and a circulation pump are arranged between the copper dissolving tank and the copper tank, and a spray pump is arranged on the copper tank. The filter removes Fe 2+ and Cu 2+ The solution is pumped into the copper tank and sprayed toward the anode by the first nozzle to react with the oxygen near the anode. The spray pump draws the solution from the bottom of the copper tank and sprays it toward the cathode from the second nozzle to complete the electroplating. The circulation pump draws the solution containing Fe from both sides of the copper tank. 3+ The solution is returned to the copper dissolving tank and reacts with copper to form Fe 2+ and Cu 2+, and recycled. This solution first sprays the solution in the copper dissolving tank to the vicinity of the anode, so that it reacts with oxygen and consumes oxygen, thereby reducing the adverse effects of oxygen on the electroplating process.
[0007] In summary, the existing technology for controlling the concentration of trivalent iron in the copper dissolving tank uses a pumping function structure or a motor to drive the screw rod to reciprocate to achieve liquid inlet and outlet and Fe 3+ The structure is complex and the actual control is difficult.

[0049] The technical solution of the utility model is as follows:
[0050] The control scheme includes a copper dissolving tank 1, a high-concentration copper temporary storage tank 2, a secondary tank 3, an electroplating reaction tank 4 and a low-concentration copper temporary storage tank 5.
[0051] Copper dissolving tank 1: multiple rows of copper baskets 20 filled with copper balls, adding Fe 3+ Reacts with copper to produce Fe 2+ and the required Cu 2+ ;
[0052] High-concentration copper temporary storage tank 2: temporarily stores high-concentration copper solution from copper dissolving tank 1 and provides high-concentration copper solution for auxiliary tank 3;
[0053] Sub-tank 3: Main tank body, providing sufficient Cu for electroplating copper reaction tank 4 2+ ; When the concentration of auxiliary tank 3 is lower than the set value, it can be replenished from the high-concentration copper temporary storage tank 2;
[0054] Electroplating reaction tank 4 (main tank): This tank is used for electroplating, and the cathode consumes Cu 2+ At the same time, the anode converts Fe 2+ Oxidized to Fe 3+ The low-concentration copper solution produced after the reaction flows to the low-concentration copper temporary storage tank 5, while the high-concentration copper solution is continuously supplied from the auxiliary tank 3.
[0055] The low-concentration copper temporary storage tank 5 receives the solution after the reaction from each electroplating reaction tank 4, and continuously delivers the low-concentration copper solution to the copper dissolving tank 1 for copper dissolving.
[0056] Fe 3+ Concentration monitoring sensor: monitors the Fe3+ concentration in the high-concentration copper temporary storage tank 2 after copper dissolution to determine whether the copper is fully dissolved. At the same time, monitors the Fe3+ concentration in the low-concentration copper temporary storage tank 5. 3+ Conduct monitoring.
[0057] Cu 2+ Concentration monitoring sensor: mainly used to monitor the Cu in the auxiliary tank 3 2+ Concentration provides a determination parameter for solution circulation and circulation flow rate.
[0058] The specific control method of the utility model is as follows:
[0059] (1) As the electroplating reaction tank 4 continues to electroplating, the Cu in the auxiliary tank 3 2+ The Cu in the auxiliary tank 3 is continuously consumed. 2+ The concentration monitoring sensor monitors the Cu in the auxiliary tank 3 2+ If the fluctuation of Cu 2+ If the concentration is within the set range, it will not affect the efficiency and effect of electroplating. At this time, only the auxiliary tank 3 and the electroplating reaction tank 4 are circulating the solution. That is, the pump of the auxiliary tank 4 continuously supplies liquid from the auxiliary tank 3 to the electroplating reaction tank 4, and the filter barrel filters and removes impurities from the solution. The hand valve is always open, and the flow meter monitors the flow. The flow can be controlled by the pump frequency conversion or the hand valve. After the electroplating, the solution in the electroplating reaction tank is Cu 2+ A portion of it is consumed and flows back into the auxiliary tank 3 for mixing circulation.
[0060] (2) If Cu 2+ The concentration monitoring sensor detects the Cu 2+ When the concentration is lower than the set threshold, the electric ball valve (or pneumatic ball valve or electric / pneumatic diaphragm valve or other automatic valves) between the high-concentration copper temporary storage tank 2 and the auxiliary tank 3 is opened, and the solution in the high-concentration copper temporary storage tank 2 is transported to the auxiliary tank 3 through the pump, so that the Cu in the auxiliary tank 3 2+ At the same time, the low-concentration copper electroplating solution in the electroplating reaction tank 4 is no longer circulated to the auxiliary tank 3, but by opening the electric ball valve (or pneumatic ball valve or electric / pneumatic diaphragm valve and other automatic valves) between the electroplating reaction tank 4 and the low-concentration copper temporary storage tank 5, the low-concentration copper solution in the electroplating reaction tank 4 flows into the low-concentration copper temporary storage tank 5 through the height difference. When the solution in the low-concentration copper temporary storage tank 5 reaches a certain amount, the pump between the low-concentration copper temporary storage tank 5 and the copper dissolving tank 1 is started to transport the low-concentration copper solution to the copper dissolving tank 1 for copper dissolving. The flow rate is controlled by the pump to make the solution in the low-concentration copper temporary storage tank 5 flow into the copper dissolving tank 1 at a certain flow rate, so that the Fe in the solution3+ There is enough time for the copper ball to contact and react. The high copper concentration solution after the reaction enters the high concentration copper temporary storage tank 2 for temporary storage. The Fe 3+ The concentration monitoring sensor will detect the Fe 3+ The concentration is monitored in real time. If the high concentration copper temporary storage tank 2 is detected, Fe 3+ If the concentration is higher than the set threshold, the electric ball valve (or pneumatic ball valve or other automatic valves such as electric / pneumatic diaphragm valve) between the high-concentration copper storage tank 2 and the copper dissolving tank 1 will be opened, and the pump will pump the solution back to the copper dissolving tank 1 for copper dissolving, and the test will close or reduce the liquid supply from the low-concentration copper storage tank 5 to the copper dissolving tank 1.
[0061] (3) During the copper dissolution process, the copper balls will dissolve and tiny copper particles will fall off and sink to the bottom of the copper basket. After a long period of accumulation, it will be difficult to clean up. At this time, CDA (i.e., air inlet pipe 8) is needed to lift the tiny copper particles from the bottom and separate them from the Fe 3+ Reaction, in control, the pressure state is determined by the pressure sensor at the CDA outlet. When the pressure is greater than the set value, the flow rate of CDA is increased, and when the pressure is less than the set value, the flow rate of CDA is reduced.
[0062] (4) A cross-beam sensor is installed on both sides of the copper basket. The copper basket is a mesh basket to facilitate contact between the solution and the copper balls. Holes are opened on the copper basket. When the copper balls are consumed for a long time and fall below the set position, the sensor alarms. At this time, the copper basket needs to be taken out to replenish the copper balls. A pressure sensor can also be installed at the bottom of the copper basket. When the pressure sensor value is lower than the set value, the copper balls can be replenished.
[0063] (5) The HH in the liquid level sensor 7 in the auxiliary tank 3 is used to monitor the highest liquid level of the tank body to prevent the liquid in the auxiliary tank 3 from exceeding the tank body and flowing out to cause waste and pollution. The LL in the liquid level sensor 7 in the auxiliary tank 3 is used to monitor the lowest liquid level to prevent the liquid level in the auxiliary tank 3 from being too low to supply the electroplating reaction tank 4. When the HH in the liquid level sensor 7 in the auxiliary tank 3 alarms, the electric ball valve (or pneumatic ball valve or other automatic valves such as electric / pneumatic diaphragm valve) between the concentrated copper temporary storage tank and the auxiliary tank is closed. When the LL in the liquid level sensor 7 in the auxiliary tank 3 alarms, it is necessary to open the electric ball valve (or pneumatic ball valve or other automatic valves such as electric / pneumatic diaphragm valve) between the high-concentration copper temporary storage tank 2 and the auxiliary tank 3 in time to replenish the solution in the auxiliary tank 3.
[0064] (6) HH in the liquid level sensor 7 in the electroplating reaction tank 4 (main tank) is used to monitor the highest liquid level to prevent the liquid in the electroplating reaction tank 4 from exceeding the tank body and flowing out to cause waste and pollution. WL in the liquid level sensor 7 in the electroplating reaction tank 4 is the working liquid level, which is used to ensure that the parts to be plated are completely immersed in the solution. During operation, the liquid level in the electroplating reaction tank 4 can be kept stable at the working liquid level. If certain position factors cause the liquid level to be too high, the HH in the liquid level sensor 7 in the electroplating reaction tank 4 will alarm, and the pump can be controlled to reduce the supply flow to restore the solution in the electroplating reaction tank to the working liquid level. When the liquid level is lower than the working liquid level, the pump between the auxiliary tank and the electroplating reaction tank is controlled to increase the flow rate to restore the liquid level to the working liquid level and maintain it.
[0065] (7) The HH in the liquid level sensor 7 in the low-concentration copper temporary storage tank 5 is mainly used to prevent the liquid in the tank from exceeding the tank body and flowing out to cause waste and pollution. If the volume of the low-concentration copper temporary storage tank is sufficient to accommodate all the solution, the HH in the liquid level sensor 7 in the low-concentration copper temporary storage tank 5 can be cancelled. When the LL in the liquid level sensor 7 in the low-concentration copper temporary storage tank 5 alarms, the pump is turned off to prevent dry pumping and damage to the pump.
[0066] (8) The HH in the liquid level sensor 7 in the high-concentration copper temporary storage tank 2 is mainly used to prevent the liquid in the tank from exceeding the tank body and flowing out to cause waste and pollution. If the volume of the temporary storage tank is sufficient to accommodate all the solutions, the HH in the liquid level sensor 7 in the high-concentration copper temporary storage tank 2 can be cancelled. When the LL in the liquid level sensor 7 in the high-concentration copper temporary storage tank 2 alarms, the pump is turned off to prevent dry pumping and damage to the pump.
