High leveling acid copper plating what good? Please find Dongguan Hollen

High leveling acid copper plating general failure analysis and troubleshooting Cause Symptom possible reference approach is easy to burn plating copper sulfate content is less than 1 140 g / L; 1. Analysis supplement; 2. Current greater density; 2. lower current density; 3. bath temperature is too low, less than 20 ℃; 3. raising the temperature to 24-28 ℃; 4 low chloride content; 4. analysis supplement; 5.510A excess; 5. Stop adding 510A, until the return to normal, and appropriate adjustments to the amount of; the amount of time too, you can put the right amount of activated carbon powder on the filter pump to do inside the inner loop filter, until the resumption of normal, clean the filter pump; 6. 510B inadequate; 6 Add the proper amount 510B; 7. uneven mixing. 7. Check and adjust cathode movement or air mixing device. Poor dispersion bath 1. Current too low; 1. Adjust the current; 2. Low sulfate content; 2. Analysis supplement; 3. chloride is too high; 3. treatment chloride ions to the process range; 4. bath temperature exceeds 35 ℃; 4. lower tank temperature to 24-28 ℃; 5. 510B, less 510A. 6. appropriate to add 510A, 510B temporarily replace 510MU consumption. Coating of brightness difference 1. brightener imbalance; 1. Adjust the ratio of brightener; 2. Organic impurities; 2. Full and activated carbon filtration or treatment with hydrogen peroxide; 3. bath temperature is high; 3. Reduce the bath temperature to 24- 28 ℃; 4. anode area is inadequate; 4. supplement anode; 5. Current too small. 5. The appropriate increase in current. Coating filled difference of less than 1 brightener; 1. Follow the instructions to add brightener added; 2. chloride ion excess, the main salt low, Lin Yang rarely like. 2. stop into the chloride ion, so that chlorine ions in the consumption reduced; serious, dilution, plus zinc, silver, sulfuric acid and other methods to reduce the content of chlorine ions; Also note that supplement the main salt and phosphor of the anode. Plating pinhole pitting 1. Organic impurities; 1 with hydrogen peroxide and activated charcoal; 2.510MU less; 2. appropriate complementary; 3. Filter is not complete; 3. Strengthen the filtering effect; 4. inadequate air mixing; 4 . play pores is not too small (diameter of not less than 3 mm), appropriate adjustments cheer strength; 5. filter pump suction air; 5. filter pump inlet to stay away from playing the pores, preventing the intake air; coating covered with small particles 1. plating There are tiny particles suspended in the fluid (such as activated charcoal powder); 1. Continuous filtration bath, the number of cycles per hour, no less than four times, it is recommended to use aid; 2. stirred by the air is polluted; 2. Best Use No Oil pump cheer; 3. adding copper sulfate, filtered inadequate; 3. Strengthen filtered thorough filtration bath; 4. inappropriate anode. 4. The use of qualified Lintong anode. Coating dendritic or striped excessive or inadequate 1. 510 A 510B; 1. brightener 510B plus adjustment or a little hydrogen peroxide; 2. chloride deficiency. 2. After analyzing the supplement. 1. The main anode passivation temperature is too high or too low salt; 1 dilution bath, adjust the temperature to 24-28 ℃; 2. anode bags clogging; 2. Clean anode bags; 3. bath is a large number of iron impurities serious pollution . 3. Dilution bath, add the appropriate main salt.
