5. Common faults and solutions
| Fault phenomenon | Possible causes | Solution |
| High brittleness of coating | 1. pH value ≤ 4 or ≥ 6.3 | 1. Adjust to 5.6-5.9 |
| 2. The temperature is too low and the thickness is too thick | 2. Increase temperature and reduce plating thickness | |
| 3. Organic or non-metallic impurities pollution | 3. Major processing | |
| 4. Excessive main light agent and additives | 4. Reduce pH to 4, electrolysis | |
| 5. Excessive Dk and excessive iron impurities | 5. Reduce Dk and remove iron | |
| 6. Low boric acid or high zinc and low potassium | 6. Adjust to Range | |
| 7. Acid washing hydrogen permeation | 7. Add corrosion inhibitor | |
| Small range of bright current | 1. Less softener and less boric acid | 1. Add in place |
| 2. Improper pH value | 2. Adjust to 5.6-5.9 | |
| 3. Zinc too high or too low | 3. Adjust to normal | |
| 4. Too high or too low Potassium chloride | 4. Adjust to normal | |
| 5. High iron impurities | 5. Iron removal | |
| 6. Excessive foreign metal impurities | 6. Zinc powder | |
| 7. Temperature too high | 7. Reduce temperature | |
| Skip plating | 1. High zinc and low potassium | 1. Adjustment |
| 2. Excessive brightener | 2. Electrolysis at low pH | |
| 3. Too much loading | 3. Reduction | |
| 4. Improper pH value | 4. Adjustment | |
| 5. Temperature too high | 5. Cooling | |
| 6. Excessive organic and non-metallic impurities | 6. Major processing | |
| 7. Nitrate or Hexavalent chromium | 7. See processing method | |
| 8. Poor pre-treatment in low areas | 8. Improvement | |
| The coating is not bright | 1. Dk is not driving very well | 1. Identify reasons for improvement |
| 2. Excessive organic and non-metallic impurities | 2. Major processing | |
| 3. Insufficient or too short anode | 3. Improvement | |
| 4. Poor conductivity | 4. Inspection and improvement |
