TIN PLATING

An ISO 9001 :2008 CERTIFIED COMPANY. NSIC – CRISIL RATING SE 3A CERTIFIED

Tin plating is used extensively on many different types of metals, both ferrous and nonferrous. Tin is A gray-white, soft, and ductile metal that is not easily oxidized in air. Electrodeposited tin has good conductivity and corrosion resistance while enhancing solder ability of substrates that are not otherwise easily soldered to. Tin is generally considered non-toxic and non-carcinogenic and as such its use is generally approved for food contact applications. Tin plating is provided in two general types of deposits: bright tin and matte tin. Both can be obtained from an alkaline or acidic bath and both are electrolytically applied. The acidic chemistries are most common today.

Bright Tin

Properties

  1. More Esthetic Appeal
  2. Increased Lubricity
  3. Corrosion Protection
  4. Electrical Enhancements To The Substrate

Uses

Electrical contact applications such as: bus bars, Terminals, and switching components that don’t require soldering.


Matte Tin

Properties

  1. Solderable
  2. Non-Reflective
  3. CCorrosion Protection
  4. Electrical Enhancements To The Substrate

Uses

Electrical contact applications such as: bus bars, terminals, and switching components where soldering is Required For substrates alloyed with zinc it is generally recommended to apply A diffusion barrier or nickel or copper to Prevent zinc migration into the tin deposit. Tin deposits can have the potential to form tin “whiskers” on the Surface of the deposit. For applications where tin whiskers could negatively impact the function of the Product, tin-lead plating is used.


Tin is not good for low temperature applications as it changes structure and loses adhesion when exposed to Temperature below 40° F.
