Technical Plating is one of a select few companies in the United States to do Hot Tin Dip. Hot Tin Dip is the process of immersing a part into a bath of pure molten tin at a temperature greater than 450°F. The coating consists of a very thin intermetallic layer that first forms at the interface of the base material and the tin, followed by a layer of pure tin. Hot Tin Dip provides excellent solderability, prevents oxidizing, and improves corrosion and wear resistance. TPI is able to perform Hot Tin Dip as a rack process.

*as this process differs from standard plating processes, TPI will usually require samples prior to quoting to determine appropriate pricing and tooling charges.
