1. Etching process requires less side etching and raised edges to enhance the processing factor in metal etching

The longer the metal is in the process of passing through the etching solution, the more severe the side etching will be. The accuracy of the printed line is determined by the cut at the bottom, and the etching factor increases for this reason when the edge is reduced. The etched product is close to the size of the original image when the thin line of the etched line is maintained.

2. Etching process needs to improve the etching process processing rate of etched plates

The etching process requires a specific control system to set the parameters of various solutions to control the amount of copper dissolved, PH value, concentration, temperature and other uniformity, so that the etched metal processing rate remains consistent, so that the product can maintain the best state of etching.

3. Etching process needs to improve the uniformity of etching whole plate metal etching process speed

By adjusting the color spray pressure of the upper and lower nozzles during the etching solution process, the spray system is used to oscillate the nozzles so that the pressure is different in the center and edges of the whole board, which helps to improve the uniformity of the overall surface of the board. The uniformity between the board and each part of the surface is determined by the flow rate of the metal etching solution.
