Acid copper plating acid copper plating manufacturers supply Tel:? 13,580,825,571 Zhang Ping Hong QQ: 420118694 Company Website: http: //www.dghaolun.net acid copper plating bath preparation 1. inject the right amount of water in preparation tank, heated to 40-50 ℃, the desired copper sulfate was added and stirred until completely dissolved, was added 2 g / l of activated carbon powder, followed by stirring at least one hour; 2. filtration pump filter into a clean bath plating bath, add water to a level approaching and clean the filter pump; 3. Slowly add the required amount of pure sulfuric acid, then will generate a lot of heat, need vigorous stirring, so that the bath temperature not exceeding 60 ℃ (Note: Adding sulfuric acid, requires special care , should wear protective clothing, gloves goggles to ensure safety); 4. The bath is cooled to about 25 ℃, adding an appropriate amount of hydrochloric acid or sodium chloride, the content of chlorine ions up to standard, add water to level; 5. Under normal operating conditions, a small current electrolysis for 6-8 hours, and then follow the instructions to add the right amount of additives and stir to normal after the test plating can be put into normal production. 4. Daily use acid copper plating additives and precautions 510A acid copper plating: main filled agent and luster to walk. Insufficient, filling of the entire current density area will decrease; when too much, the low current density area filled of sharp decline, there will be a clear demarcation with the coating in other locations. Daily consumption by 60-90 ml / 1000 ampere-hours. 510B acid copper plating: brightener. Insufficient, the coating is easy to burn; excessive, poor or low potential brightness from white mist. Daily consumption by 50-80 ml / 1000 ampere-hours. 510MU acid copper plating: with a wetting agent, an acid copper base brightener. Insufficient coating prone to pitting in serious condition occurs when loose striped plating high potential in the region; severe overdose, low potential will produce fog coating. Daily consumption by 50-80 ml / 1000 ampere-hours.
