Matte tin plating is a widely used electroplating process used to deposit a uniform layer of tin on metal surfaces to provide corrosion protection, increase solderability and enhance appearance. This tin layer has a certain "matte" or "non-glossy" effect, as opposed to shiny tin plating, and is characterized by the following:
1. Non-glossy appearance: As the name suggests, the surface of the "matte tin" layer is not glossy; it has a uniform matte appearance.
2. Good solderability: Matte tin plating layer provides excellent solderability, which makes it particularly popular in the electronics industry for improving the solderability of electronic connectors and other electronic components.
3. Strong corrosion resistance: Electroplated matte tin layer can effectively prevent the substrate oxidation and other types of environmental corrosion, so it can extend the service life of the substrate.
4. Uniform thickness distribution: Since the plating is formed by electrolytic reaction in the electroplating bath, it is possible to form a uniform and consistent coating over the entire surface of the workpiece, including edges and recesses.
5. No need for polishing: Due to the non-glossy characteristics of matte tin, the plated product can be used directly without further mechanical polishing treatment.
The general flow of the matte tin electroplating process is as follows:
① Pre-treatment: Before plating, the workpiece should be thoroughly cleaned and pre-treated to ensure that the surface is smooth and free of oil and other contaminants.
②Electroplating: Pre-treated workpieces are placed in a plating solution containing Bigely matte tin additives, and a lusterless tin plating layer is deposited on the surface of the workpieces by electrolysis.
③ Post-treatment: After plating, the workpiece may require post-treatment such as rinsing and drying to ensure the quality of the plated layer and corrosion resistance.
Matte tin electroplating is commonly used in electronics, electrical, food packaging and other areas where improved corrosion resistance and enhanced solderability are required. Due to its favorable properties, matte tin plating plays an important role in industrial production. In order to ensure solderability and other plating properties, we need to use matte tin additives from Bigely.
