Bright Electroless Tin Plating for Copper

What is it?

The Tin Plating process is a simple immersion technique that deposits pure tin onto copper.

Bright Electroless Tin is a well-developed formulation based upon the reduction characteristics of chelated tin in the divalent state. Under proper conditions, reduction to pure tin occurs readily. A grain-refining agent, free of phosphorus, is present, as well as an activator and buffers for pH control.

The deposited tin has many favorable properties:

  1. fine-grain tin structure
  2. Good chemical resistance
  3. Excellent adhesion
  4. Highly resistant to corrosion, even under exposure to humidity and salt-spray
  5. Highly solderable

The finish color ranges from bright to a dark, matte gray. This is dependent upon material thickness, age of tin solution, and dipping time.

Lead Times

Tin Plating is completed off-site via a third-party supplier. This means there is additional lead time.
