1, affecting the uniformity of electroplating: too violent or improper blowing in the water tank will lead to uneven flow of electrolyte, thus affecting the uniformity of electroplating layer.
2. Increase impurity content: Too large or too many bubbles blown out of the water tank will bring dissolved oxygen and air into the electrolyte, thus increasing impurity content and affecting the quality of the electroplating layer.
3. Reduce the electroplating rate: too large or too many bubbles blown by the water tank will affect the ion transfer rate in the electrolyte, thus reducing the electroplating rate.
