High end copper foil tin plating: excellent quality and wide application

high-end Copper foil tin platingThe widespread application of technology in modern industrial fields is self-evident. This article will provide a detailed introduction to the production process types and respective characteristics of tin plated copper foil by Advanced Institute Technology.
1、 Alkaline Tin Plating Process
Alkaline tin plating is a common tin plating process, which results in finely crystallized coatings, low porosity, and excellent brazing performance. Due to the superior characteristics of this process, alkaline tin plating is widely used in various fields.
Firstly, the crystallization of alkaline tin plating is fine, which can improve the density of the coating. This makes tin plated copper foil have better corrosion resistance and durability, and can be used for a long time in harsh environments.
Secondly, alkaline tin plating has a lower porosity, which makes the bonding between the tin plating layer and the copper foil more firm. This greatly enhances the mechanical properties of tinned copper foil, making it excellent in both tensile strength and bending performance.
In addition, the brazing performance of alkaline tin plating is also excellent. Tin plated copper foil can be reliably brazed to other materials, thereby expanding its application range. For example, alkaline tin plated copper foil plays a crucial role in fields such as marine cables, automotive wires, and capacitors.

2、 Acid Tin Plating Process
Compared with alkaline tin plating, acidic tin plating has some special characteristics. Although the coating of acid tin plating is smooth and fine, with high corrosion resistance, and usually has a bright tin surface, its porosity is relatively high.
The brightness of acid tin plating makes the surface of tin plated copper foil more beautiful, which is suitable for some fields with high appearance requirements. In addition, acid tin plating has excellent corrosion resistance and can be used for a long time in humid and high-temperature environments.
However, due to the high porosity of acid tin plating, the density and bonding strength of its coating are relatively low. This limits the use of acidic tin plated copper foil in applications that require high mechanical properties.
In summary, alkaline tin plating and acidic tin plating are currently the two common copper foil tin plating processes. Alkaline tin plating has the advantages of fine crystallization, low porosity, and good brazing performance, and is suitable for various fields. Acid tin plating has the characteristics of smooth and fine coating, high corrosion resistance, and is suitable for fields with high appearance requirements.
