Electroless tin plating has become a key process in the manufacture of various copper parts. However, the traditional electroless tin plating method often encounters a series of problems such as discoloration of the plated layer and poor soldering performance, which makes many plating factories face great challenges in ensuring product quality. Sn-871, a electroless tin plating solution developed by Bigely, has been developed to effectively solve these problems.

The electroless tin plating solution Sn-871 from Bigely offers a good guarantee for the quality of the plated layer. First of all, it can form a uniform and flat coating on the surface of copper parts, which not only enhances the aesthetic appearance, but also provides a stable basis for the subsequent processing. Through the test, we found that after baking at high temperature (200 ℃ for 30 minutes), Sn-871 coating still maintains the original color, which fully demonstrates its good antioxidant performance.

When observed under a microscope, the surface of the plated layer using Sn-871 is free of bubbles, flaking and cracks, which proves that the potion possesses good adhesion and stability in the formation of the plated layer. This quality assurance not only extends the service life of copper parts, but also reduces the possibility of repair and replacement, thus saving the overall cost.

Importantly, Sn-871 improves the solderability of the plating. In the past, plating often affected product quality due to poor soldering, but with Sn-871, solderability is greatly improved, reducing the frequency of soldering failures and improving productivity and product reliability.
