Some precautions to be taken in the production of metal etched workpieces

With the increasing use of metal etching in the industry, people are becoming more familiar with it. That's why it is used in many industries. So, what are some things to pay attention to in the production of metal etched workpieces?
1. Learn how to handle emergency situations such as sudden power outages during production. Immediately open the medicine cylinder and remove the plate from it to avoid excessive etching, such as blocking the plate on the conveyor belt. Close the spray immediately and open the medicine cylinder to remove the plate.
2. The human element is very important, and the environmental conditions of the etching process are relatively harsh, especially the ammonia gas is very pungent. To adjust the etching process well, it is necessary to be integrated with the etching machine, and the etching parameters are not easy to maintain stability. Especially when the board enters the etching cylinder, it may come out as a scrap and the reason cannot be found.
3. The safety of etching should be taken seriously. When manually adding chemicals, a gas mask or respirator should be worn to prevent accidents, especially the smell of ammonia water, which is harmful to human health if inhaled in large quantities.

4. Save a sufficient amount of mother liquor, with enough mother liquor to replace a tank of medicine. The extraction of mother liquor is also important, and it should be extracted at the optimal ratio of each content of the medicine. Once the medicine malfunctions and is difficult to adjust, the backup mother liquor will play a key role. From this perspective, it is not advisable to frequently replace personnel during etching operations.
5. The etching process prevents excessive volatilization of ammonia water. During the etching process, as copper dissolves, it is necessary to continuously replenish ammonia water and ammonium chloride. Nitrogen has high volatility, so the exhaust should not be turned too much during plate making to avoid rapid evaporation. As the consumption of the solution increases, it is important to remember to close the exhaust valve when not making the plate to prevent ammonia from evaporating and wasting.
