[0002] Patent document CN201720607204.0 discloses a "PCB chemical copper deposition device", which includes a base, a reaction tank is provided on the base, a removable hanging basket is provided in the reaction tank, a stirring paddle is provided at the bottom of the reaction tank, and the stirring paddle is connected to a motor; a container bracket is provided on one side of the base, and a plurality of liquid medicine containers are provided on the container bracket, and the liquid medicine containers are connected to the input end of the water pump through a first pipe, and the output end of the water pump is connected to the reaction tank through a second pipe. The utility model is provided with a device for continuously supplying reactant liquid medicine, which continuously provides reactant liquid medicine to the reaction tank, and can effectively keep the concentration of the reaction solution in the reaction tank in a certain range for a long time. Even if the copper deposition reaction consumes the reactant, the reactant can be replenished in time, and the concentration of the reaction solution can still be maintained within a stable range, thereby effectively ensuring that each PCB copper deposition obtains a good effect, improving the yield of PCB copper deposition, and making the copper deposition effect of each PCB similar.

[0003] This patent places the PCB directly inside the hanging basket when performing copper deposition on the PCB without effectively fixing it. Therefore, when multiple PCBs are processed at the same time, it cannot be guaranteed that each circuit board is in full contact with the chemical solution, which affects the stability of the copper deposition and the processing quality. For this reason, we propose a high-stability PCB copper deposition device to solve the problems raised in the above background technology. Utility Model Content
