What are the advantages of the sulfate bright tin plating process? Why can't these advantages be fully utilized in the electroplating production process, resulting in a large number of substandard products? And what kind of tin plating brighteners should be used to improve the performance of the plating solution? In this article, we will answer these questions.
The sulfate bright tin plating process has the following characteristics: under normal operating conditions (for example, using the sulfate tin brightener Sn-807), not only does the cathode current efficiency and anode current efficiency of the solution remain high, but it also has the advantages of lower opening cost, relatively easier maintenance and control of the solution, etc.
In electroplating production, it is necessary to ensure that the sulfuric acid concentration in the tin plating solution remains at a relatively high level. However, it is not desirable to have an excessively high concentration. When the sulfuric acid concentration exceeds 110 milliliters per liter, it will reduce the conductivity of the tin plating solution. Therefore, it is necessary to avoid adding too much sulfuric acid.
In addition to the aforementioned advantages, the sulfate bright tin plating process has two more advantages: one is excellent deep plating capability, and the other is that a bright tin coating can be obtained by adding an appropriate sulfate brightener.
