When using acid tin plating brightener, how does the bath solution need to be prepared?
The discussion on this issue can be divided into five aspects, and we will start with the first aspect in this article.
Add 1/3 to 2/3 volume of pure water to the plating tank to be prepared first (If solderable parts in the electronics industry need to be tin plated, deionized or distilled water should be used. The reason is that tap water contains chloride ions, calcium ions, magnesium ions and other impurities,which will be attached to the plated parts as they are removed from the plating tank. And if the plated parts are not thoroughly cleaned, the performance of the soldered parts will deteriorate).
Then add the calculated amount of reagent grade concentrated sulfuric acid (the industrial grade will have more impurities than the reagent grade). At this time the temperature of the solution in the plating tank will rise rapidly, and if the speed of adding sulfuric acid is not controlled well, then it will cause the temperature to rise too quickly, making the plastic tank deformed or cracked at high temperatures.
Therefore, it is necessary to add sulfuric acid slowly when using acid tin plating brightener for tank preparation.
During the plating processing off-season, what plating factories most worry about is the poor quality of the goods , such as tank water maintenance is not good, or improper method of tank allocation, etc.. Most of the plating factory is in the production completion of the plating quality is not as good as the customer's expectations. And they found that their tin-plating process was in urgent need of optimization, searching for masters and solutions.
Bigely has been insisting on providing plating factories with products such as acid tin plating brightener for many years, and in the process of customer's use, we will also provide technical solutions according to customer's needs, and help customers to improve the straight-through rate of electroplated products.
