Tin is an extremely popular application choice in electroplating. Because Tin is so easily obtainable it tends to be much less expensive than other metals like gold and silver, which renders it as one of the most cost effective finishes. Tin is used in both the aerospace and telecommunications industries. It is also used for the manufacturing of electronic components, as tin can produce the appropriate amount of conductivity that would be required.
The appearance can either be a whitish-a hue or a glossier metallic looking finish. The whitish a finish is more commonly chosen when a dull or more matte finish is preferred whereas a glossy metallic look should be considered when something more polished is desired.
There are three types of processes that can be used in tin plating. Barrel plating, which is used for electroplating smaller parts, Rack plating, used for larger parts that are more delicate and not suitable for Barrel Plating and Vibratory plating, which is a process that is also used for more fragile parts, but tends to be more expensive.
Some benefits of this plating are:
- Resistant to corrosion
- Increased durability
- Low maintenance
- Excellent solderability
- Lower cost
