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.
