[0002] Etching liquid is a raw material for copperplate engraving. It is a liquid that is engraved by corroding the characteristics of the material. Theoretically, any reagent that can oxidize copper to form soluble copper salts can be used to etch copper-clad boards. There are six commonly used etching liquid types: acidic copper chloride, alkaline copper chloride, ferric chloride, ammonium persulfate, sulfuric acid / chromic acid, and sulfuric acid / hydrogen peroxide etching liquid. The etching liquid needs to be weighed during production. The weight is weighed according to the required weight and then the liquid is discharged. However, when the existing equipment is weighing the liquid, the liquid injection speed is too fast, which will cause the equipment to shake, resulting in inaccurate weighing values.
