Description

Technical Field

[0001] The utility model relates to the technical field of tin stripping water recovery and filtration, in particular to a tin stripping water recovery and filtration component. Background Art

[0002] The tin stripping process of the circuit board production process uses a mixed solution of nitric acid and nitrate to dissolve the anti-etching tinned layer. This mixed solution is commonly known as tin stripping water. When the concentration of tin dissolved in the tin stripping solution reaches 60-80 g / L, the tin stripping solution can hardly continue to dissolve the tinned layer on the circuit board.
