During the processing of the precision etching line, the anti-etching layer will fall off due to various reasons. The causes are the same in different metal etching processes. In part, for the anti-etching layer to fall off, we find out the cause and preventive measures.

First of all, what causes the anti-etching layer to fall off during the etching process? What are the main points that cause the anti-etching layer to fall off during the etching production process. The following hardware etching will introduce the following points:

1. The metal surface is not clean and degreasing.

2. The baking temperature and time of the anti-etching layer are not enough.

3. The temperature of the etching solution is too high.

4. The concentration of the etching solution is too high.

5. The anti-etching layer material has exceeded the shelf life.

For the above-mentioned problems that caused the anti-etching layer to fall off during the hardware etching process, there are the following points to find out the prevention and elimination methods:

1. Strengthen the cleaning of the metal surface, and confirm whether the metal surface is clean when coating the anti-etching layer.

2. Reduce the concentration of the etching solution according to the characteristics of the metal material in the etching process.

3. Replace qualified anti-etching layer materials.

4. Bake in strict accordance with the requirements of various metal processing techniques.

5. Reduce the temperature to the specified range of the etching metal processing technology.
