Product Description
Electroplating with a tin–bismuth alloy is an environmentally friendly, lead‑free solderable coating process that forms a tin–bismuth alloy layer on the workpiece surface via electrodeposition. The coating exhibits uniform thickness, excellent solderability, strong resistance to whisker formation, and good corrosion resistance. It is suitable for connectors, electronic components, and other applications, meeting the requirements of electronic assembly and soldering. With stable process control and straightforward wastewater treatment, it represents a mature surface‑treatment solution in the electronics industry for replacing tin–lead coatings and mitigating “tin pest” failures.
