Improved Solderability With Reflowed Tin

What Is Reflowed Tin?

Reflowed tin is a process that results in improved solderability as opposed to standard electroplated tin. After a part has been electroplated with tin, the part is reheated above the melting point of the tin plating (greater than 450°F), then cooled.

Reduces The Internal Stresses Of Electroplating

Tin reflowing reduces the internal stresses that arise during the electroplating process that have been thought to contribute to tin whisker formation.

The Reflowed Tin Advantages

  • The reflow process improves the bond between the tin plating and the base material.
  • Parts treated with reflowed tin exhibit excellent corrosion resistance.
  • Reflowed tin provides a smooth attractive finish that is safe for food handling equipment.
  • Reflowed tin plating provides good thickness uniformity and a glossy surface finish.
  • Reflowed tin corrodes at a slower rate than regular tin plating.

Reflowed Tin Plating Is Lead Free

One of the major benefits of reflowed tin plating is that unlike solder plating, reflowed tin is lead free. As many industries are looking to remove lead from their products because of its health and environmental issues, reflowed tin is an attractive option.

RoHS Compliant

Reflowed tin is compliant with RoHS standards that govern the use of hazardous products in electronic products.

Interesting Facts About Tin

    • Tin Pan Alley has two possible derivations. Both from the turn of the 20th century and both are from New York City.

      One story says that a columnist visiting studios that were concentrated in one building heard so many pianos playing at once that the cacophony sounded like tin pans being banged.

      The second story is similar in that in the area of New York that became the Flat Iron District, there were so many people playing out of tune pianos at one time that if you walked by or into an alley it sounded like tin pans being pounded.

    Take your pick!

    • China & Indonesia are the World’s largest producers of Tin. The U.S. no longer mines tin.
    • Tin foil is made out of aluminum.
    • The word “tin” is not of Latin Origin. Websters thinks it derives from an old Indo-European Language
