[0002] In the production and processing process of printed circuit boards, etching is one of the key processes, which dissolves the copper layer in the non-circuit area through chemical solution (etching solution), thereby forming the required circuit pattern. The traditional etching process usually uses a soaking type etching device to immerse the circuit board in etching solution of fixed concentration and temperature for processing.

[0003] However, there are many defects in the existing circuit board processing soaking technology. The amount and concentration of etching solution required for different sizes of circuit boards in production are different, and the etching solution required for circuit board etching is corrosive. If a concentration sensor is used to detect the concentration of etching solution, the concentration sensor will be corroded and damaged. However, using PH test paper to detect the concentration of etching solution requires a large amount of PH test paper, which not only increases the cost, but also greatly increases the complexity of the detection process.
