• 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:

  • In the sulfate tin plating process, tetravalent tin is usually not directly involved in the formation of the plated layer, but it can occur due to oxidation of divalent tin in the plating solution. This oxidation can be triggered by several factors, including anodic reactions during the plating process, natural oxidation of the bath, and improper storage and handling.

  • The high-temperature nickel plating process is an industrial surface treatment technology that involves depositing a nickel coating on the surface of a metal or other material. The main purpose of this treatment technique is to improve the corrosion resistance, abrasion resistance, and high temperature resistance of the material, as well as to improve its surface finish. Below are a few important roles and application areas of the electroplated high temperature nickel process:

  • The roughness of the nickel plated layer is closely related to the nickel plating brightener used. Brightener is a chemical additive added to the plating solution, and its main function is to improve the gloss and flatness of the plated surface. The following points explain the effect of nickel plating brighteners on the roughness of the nickel plated layer:

  • In the electroplating industry, proper control of additives in nickel baths, especially nickel plating softeners, is crucial to ensure the quality of the nickel layer. A moderate amount of additives can optimize the brightness and toughness of the nickel layer, however, an excessive amount of softener can lead to a series of problems, such as increased brittleness and stress concentration of the nickel layer, and can even cause cosmetic defects and decreased adhesion. As a result, determining whether the amount of softener in the nickel plating bath is appropriate becomes a critical step in the plating process.

  • During the plating degreasing process, it is important to properly clean grease and dirt from the workpiece, especially from inside the blind holes, as this ensures uniformity, adhesion and overall quality of the plated layer. Here are some suggestions for cleaning blind holes in plated parts:
