Tin(II) tetrafluoroborate

Tin(II) tetrafluoroborate (CAS 13814-97-6) is an inorganic tin salt supplied as an aqueous solution for use in electrochemical and surface treatment processes. It functions as a soluble source of stannous ions in electrolytic baths.

This chemical enables controlled tin deposition onto metal substrates during industrial manufacturing. In electronics, it is used in electroplating baths to deposit uniform tin coatings on printed circuit board traces and connector pins.

Consistent layer thickness and solderability are critical for lead frames and semiconductor packaging. The compound supports tin-lead and pure tin plating in high-speed reel-to-reel operations for the electronics industry.

In the printing industry, it serves in the production of tinned metal substrates used for packaging applications. These applications require corrosion-resistant surfaces to ensure the longevity and safety of the final products.

Mining and metals processors use it in surface finishing lines where fluoroborate-based electrolytes offer improved bath stability. These systems provide higher current density tolerance compared to traditional sulfate systems.

The product is commercially available as an aqueous solution, typically at concentrations suited for direct use in plating bath formulation. It is supplied in technical grade, with specifications aligned to industry standards.

Quality control measures cover tin content and free acid levels to ensure performance in industrial-scale operations. Packaging is available in drums and intermediate bulk containers to meet various logistics requirements.
