Slit sheet etching process precision tolerance effects

Stainless steel slit sheet etching processing is a high-precision processing technology, its accuracy tolerance of the factors affecting the material, etching solution, equipment and exposure equipment, in addition to the above mentioned factors, but also includes the following factors:

1. Post-etching processing: Post-etching processing steps, such as cleaning, drying, trimming, etc. will also affect the accuracy tolerance of slit-sheet etching.

2. Air pressure and flow rate: The air pressure and flow rate during the etching process of stainless steel slit piece etching will also have an impact on the accuracy. Changes in air pressure and flow rate may lead to instability in the etching rate, thus affecting the accuracy.

3. The hardness of the metal material: the hardness of the metal material is too high or too low may affect the accuracy of etching. Too high hardness may lead to residue in the etching process, affecting the flatness of the slit; too low hardness may lead to excessive erosion in the etching process, affecting the depth and width of the slit.

4. Concentration and temperature of etching solution: the concentration and temperature of etching solution will also affect the precision of etching. Etching solution concentration is too low or too high may affect the etching effect, resulting in the width and depth of the slit does not meet the requirements. At the same time, the temperature of the etchant will also affect the etching rate and the shape of the slit.

5. The shape and position of the slit: the shape and position of the slit will also affect the etching accuracy. Irregular shape or incorrect position of the slit may lead to errors in the etching process, affecting the accuracy.

6. Maintenance and calibration of equipment: Good or bad maintenance and calibration of equipment also affects the precision tolerance of slit piece etching. Improper maintenance of equipment may lead to mechanical failure, affecting the accuracy of the equipment; improper calibration of equipment may lead to errors in the process, affecting the etching effect.

7. Operator's skill and experience: operator's skill and experience is also one of the factors affecting the accuracy tolerance of slit sheet etching. Operators with insufficient skills and experience may not be able to accurately grasp the etching process parameters, thus affecting the etching effect.

In summary, the accuracy tolerance of stainless steel slit slice etching processing is affected by a number of factors. In order to achieve high-precision slit sheet etching processing, it is necessary to comprehensively consider the material, etching solution, equipment, exposure equipment, and various operational factors, and take corresponding control measures to ensure the stability of the process and the reliability of the accuracy.
