/ Tin Electroplating
Tin Electroplating is mostly used for imparting the
properties of tin on other metal surfaces. Tin are slowly deposited on the
surface of the other metal, hence the process is carried out in a
electrolytic solution with a tin sticks. The properties of tin metal are
also transferred to that metal surface. Tin electroplating is widely used in
the electronics and chemical industries.
Benefits of Tin Plating
Tin plating is a lower cost alternative than some
protective coatings. Tin also has a good level of conductivity enhancement
properties (as opposed to silver which has higher conductivity) which may be
of benefit to manufacturers seeking to enhance this property somewhat
without adding too much to the price.
Tin offers excellent solderability
Tin can cover a wide range of shapes
Tin provides corrosion resistance
As this is
an electrolytic process it is necessary to use jigging, racking or wiring to
provide for electrical current conductivity. Some shapes lend themselves
more easily to this than others. In some cases the addition of a sprue or
hole is necessary. Please consult your plating adviser prior to finalising
design if you intend to use this finishing process.
Colour & Aesthetics
plating has a 'whitish grey' hue and is usuallyapplied without the layer of
bright nickel used in decorative coatings - as such tin has a dull, or matt
include: electronic components such as electronic connectors or bus bars,
commercial cooking equipment and jewellery.
Substrates suited to this coating
Tin can be
plated over most metal substrates but commonly is used on lower value
substrates such as mild steel or copper alloys.
