Circuit Board Work

Gleco offers rack and barrel matte tin plating for those customers seeking a cost-effective, corrosion-resistant finish that will retain its color in high-temperature environments.

Containing few additives, matte tin is non-toxic and non-carcinogenic, containing 100% pure tin. Gleco offers ASTM-B-545, MIL-T-10727, and AMS-2408 Dull Matte Tin plating.

The Matte Tin Process

Matte tin is electrodeposited onto metal substrates using the following process:

  1. Cleaning: Electrolytic degreasing and rinsing are used to ensure the substrate surface is free of contaminants such as oil and grease.
  2. Solution preparation: Electrolytic baths can contain acid tin, alkaline tin, or methyl sulphonic acid.
  3. Electrodeposition: Cathodes and anodes are used to layer the matte tin onto the components.
  4. Post-processing: Parts are passivated, and heat treated as necessary.

Benefits of Matte Tin Plating

Matte tin plating offers several advantages, including:

  • Anti-galling properties
  • Corrosion resistance
  • Low-contact resistance
  • No whiskering
  • Affordability
  • Solderability
  • Ductility

Matte Tin Plating Uses

Matte tin plating is used to provide a dull, white conductive finish to the following materials:

  • Aluminum
  • Brass
  • Bronze
  • Copper
  • Stainless Steel
  • Steel

Matte tin deposits have low carbon content. This makes them ideal for use on circuit boards and electronic components that employ lead-free soldering.

In addition to the electronics industry, matte tin is also used by the aerospace, automotive, food processing, telecom, and medical industries for:
