We offer both rack and barrel bright acid tin plating.
Overview: Tin plating is typically used for electrical applications because of its excellent electrical conductivity and solderability. Tin plating is also used for heat sensitive applications such as fire fighting, food processing equipment, and for kitchen & domestic tableware.
Thickness: Typical thicknesses of 5-30µm are deposited although greater thicknesses of up to 80µm can be achieved where required, for example, components specified for service at paper mills and other environments where hydrogen sulfide in the atmosphere corrodes silver and other platings.
Tanks: We offer tank sizes up to 5' x 2.5' x 2.5'.
Barrel: We offer barrel sizes up to 3' x 3' x 3'.
Rate Of Deposition: Under typical conditions tin plating occurs at a rate of about 10µm in 11 minutes, however, tin plating is not always even and where minimum thicknesses are required longer processing is needed, for example, to achieve a minimum thickness of 25µm a process time of 35 minutes would be required, or longer for complex components.
Tin Plating Brass: On brass components to be tin plated as an aid for solderability or for electronic purposes, it is advisable to apply a thin coating of either copper or preferably nickel before tin plating.
Electronics Applications: For electronic components, the use of a copper additive is recommended to prevent "whiskering" of the deposit in storage.
