Because of its excellent conductivity and corrosion resistance, tin is a preferred choice for improving the solderability of otherwise difficult-to-solder substrates. If you’re seeking tin plating services, our team offers both matte and bright finishes to meet your application needs.
Bright vs. Matte Tin Plating: Which Is Right for You?
Pure tin is available in both bright and matte finishes. Bright tin has a high shine and is typically favored for electrical contact applications, such as bus bars, terminals, and switch components that are not soldered. However, soldering to bright tin may cause dewetting due to the organic additives used to achieve its brightness. For solderable applications, matte tin is preferred because it does not contain these organic additives.
Things to Keep in Mind When Looking for Tin Electroplating Services
Over time, tin deposits will oxidize, so proper storage of plated components is important to prolong their shelf life. Additionally, preplating with other metals, commonly nickel, provides an effective diffusion barrier and can significantly extend the solderability lifespan of tin-plated parts.
Relevant specifications for tin plating include MIL-T-10727, ASTM B545, and AMS 2408.
Benefits of Tin-Plated Products
The benefits of tin electroplating are abundant, and include:
- Corrosion Resistance – Creates a double barrier that protects metal substrates from corrosion, moisture, and beyond, which extends product lifespan
- Solderability – Improves the surface for soldering by creating reliable and strong solder joints and ensures solid electrical conductivity
- Durability – Adds a layer of protection against abrasion and reduces the friction on moving parts, which decreases wear and the maintenance required
Additionally, tin plating services are often sought out because tin is cost effective when compared to other metals that are used for plating, which helps achieve product longevity without high costs.
