Description

Technical Field

[0002] Cyanide-free electroless gold plating solution is a chemical solution used in the electroless gold plating process. It is mainly used to deposit a gold plating layer onto the surface of a substrate through a chemical reduction reaction without the use of cyanide. Unlike traditional electroplating gold technology, electroless gold plating does not rely on electric current, but automatically forms a metallic gold layer on the surface of the substrate through a chemical reaction. During the gold plating process, the solution needs to be prepared, and automatic preparation equipment is used.

[0003] An existing high-efficiency atomized chemical solution preparation device (authorization announcement number: CN219849118U) has the following defects: In the above device, the rotating bar and the stirring rod cooperate with each other, which greatly increases the disorder of the chemical solution raw materials during stirring, thereby making the mixing of the chemical solution raw materials more thorough. However, in the process of preparing cyanide-free chemical gold plating solution, it is necessary to precisely control the amount of multiple raw materials and uniformly add them to ensure the efficiency and stability of the solution preparation. Therefore, this utility model is proposed. Utility Model Content
