Maintenance-free bright plating tin and lead-tin alloy plating solution

◇ characteristics

(1) The gloss and solderability of the coating are comparable to those of the imported plating solution.

(2) Precipitation: After electroplating of other electroplating solutions, a large amount of precipitate is produced; after electroplating, the precipitation of the solution is extremely small.

(3) Maintenance of electroplating solution: This product does not have the influence of additives on the electroplating solution, so the process of maintaining the electroplating solution is eliminated; when the plating solution is reduced, it is only necessary to add a cylinder (or a cylinder) and an appropriate amount of distilled water. .

(4) The life of the plating solution: Because the amount of additives used in this product is very small, most of the electroless reaction does not occur in the electroplating process, and the stabilizer can form a stable chelating agent with Sn and Pb; therefore, the plating solution in the electroplating process of the product The composition changes little, so it has a long service life.

◇ Use and usage: This product is mainly used for electroplating of electronic components.

◇ Formula (g)

◇Production method Mix the components evenly.

◇ Note : This product is bright tin or lead-tin alloy plating solution. When the plating solution is reduced, only the matching cylinder liquid is added. When the temperature is high or the plating time is long, the appropriate amount of distilled water is added, and almost no precipitation occurs, which can be maintenance-free.
