Description

Technical Field

[0001] The utility model belongs to the field of stirring devices, in particular to a recycling stirring device for tin stripping waste liquid. Background Art

[0002] Tin stripping liquid is one of the largest chemical materials used in the production of printed circuit boards. It is also called tin stripping agent. It is a single-liquid, peroxide-free, fluorine-free, and chelating agent-free high-efficiency tin stripping and lead stripping liquid. It is suitable for the stripping of tin plating, tin-lead alloy plating, and tin solder joints. It is suitable for the stripping of tin plating on precision parts without any damage to copper. It is suitable for small parts with uneven thickness and high precision. The waste tin stripping liquid will contain some solid waste residues, and the waste tin stripping liquid is the waste liquid generated by removing tin or tin-lead alloy from the Sn / Pb or Sn plating that protects the pattern without damaging the copper substrate.

[0003] When the existing stirring device is in use, a large amount of tin stripping waste liquid is likely to remain on the inner wall of the device after the tin stripping liquid inside the stirring device is discharged and used, and the existing stirring device is not convenient for cleaning the liquid on the inner wall, so that there is a large amount of residue on the inner wall, thereby reducing the use of the device. At the same time, there is a large amount of solid impurities in the existing tin stripping waste liquid, which affects the use of the tin stripping waste liquid, and the existing stirring device cannot filter the solid impurities in the tin stripping waste liquid as needed, which reduces the practicability of the device.
