A customer inquired about the use of methyl sulfonic acid as a tin plating additive in the production process. Due to the presence of methyl sulfonic acid in the warehouse for a long time, the color has turned yellow. Can it still be added to the plating solution for use?
Based on on-site experience and the characteristics of Sn-819, a methyl sulfonic acid tin plating additive, Bigley Technology analyzed that a sufficient concentration of methyl sulfonic acid in the plating solution can improve the conductivity of the plating solution, broaden the current density range, and improve the dispersion ability of the plating solution.
Due to the high price of methanesulfonic acid, many electroplating factory customers purchase cheaper methanesulfonic acid in order to save production costs. Little did they know that it was easy to purchase inferior, insufficient, and yellowed methyl sulfonic acid. Using such methyl sulfonic acid, due to its low content, requires adding more to achieve the corresponding concentration, which will undoubtedly increase production costs; Moreover, it will bring more impurities into the plating solution, resulting in a decrease in the performance of the plating solution, thereby reducing the dispersion ability of the plating solution, leading to low zone darkening, leakage, and other fault phenomena of the coating; In addition, the rapid accumulation of impurities in the plating solution will increase the processing frequency and maintenance cost of the plating solution, which is also another reason for the short service life of the plating solution.
Therefore, in the production process of using methyl sulfonic acid as a tin plating additive, yellowing methyl sulfonic acid cannot be added to the plating solution. Otherwise, it will not only reduce the performance of the plating solution, increase the failure rate, but also increase production costs.
