TINBRIGHT SN is an acid tin plating brightener based on a stannous sulfate (SnSO₄) system, designed to produce high-quality tin deposits ranging from high-bright to semi-bright finishes.
The system is suitable for high-reliability applications such as connectors, EV busbars, and automotive electronic components.

Features

• Produces deposits ranging from bright to semi-bright finishes
• Strong adhesion and uniform current distribution
• Wide current density range, excellent coverage even in low-current areas
• Outstanding solderability and ductility, solderability maintained after aging
• Crack-free, dense deposits, ideal for connectors, EV busbars, and automotive parts
• Superior corrosion resistance, compliant with MIL-T-10727-A
• Meets ASTM B678-86 solderability test requirements
• Approximately 2.6 μm thickness achieved at 2 A/dm² × 2 min
• Supports high-throughput processing, reducing operation time and production cost
