Tin Plating

We offer matte tin, bright tin and nickel flash  plating as a secondary operation for optimal performance in your electronic systems

In-House Tin Plating

We offer in-house bright and matte tin plating to accommodate photo etched parts requirements and provide quicker turnaround from raw material to finished product. Tin, a non-toxic metal, is often applied to copper, nickel, and steel electronic components such as board-level shielding, connectors, and contacts.

How does tin plating improve photo etched parts?

  • Reduces friction between metal surfaces
  • Corrosion resistant
  • Excellent ductility -optimal for parts that require forming
  • Extra protection for non-ferrous metals such as copper and nickel
  • Low contact resistance
  • Solderability
  • Thermal conductivity- can withstand high temperatures

What are the differences between matte tin and bright tin plating?

The most obvious difference is visual. Matte tin plating has a dull and white
appearance, while Bright tin plating is shiny with a reflective surface. Both
compositions are mostly pure tin. However, bright tin has about 10% more organic
material than matte, which gives it that shiny look. We offer a broad range of
plating thickness on both types of tin per individual part specifications and product

Matte Tin Plating:

  • Greater solderability than bright tin
  • Less material stress with higher temperatures
  • Color retention under high heat

Bright Tin Plating:

  • Aesthetically attractive surface
  • Provides lower friction contact, which is necessary when combining parts such as electrical boards and connectors
  • Color changes under high temperatures

Choosing the tin finish depends on the part's requirements and intended application.  Contact us with any questions you have concerning the tin plating process and how it can enhance the part's material and performance.

Nickel Flash Plating:

Another process we offer in addition to tin plating is electro nickel flash plating.  A nickel flash adds a small layer of nickel to the base metal surface. The advantages include better adhesion to a plated material and increased plating uniformity.  For example, nickel is usually a base coat under gold plating in many electronic components because it provides extra corrosion resistance, prevents the dispersion of other materials on the surface, and increases the durability of the surface.
