Excellent Solderability and Corrosion Protection

Metal Finishing Group provides Tin Plating services, applying a highly solderable, corrosion-resistant, and electrically conductive coating to a variety of metal substrates. Tin plating is a versatile and cost-effective metal finish, widely used for its blend of functional properties that are critical in electronics, food processing, and various industrial applications.

Tin plating is chosen when components require ease of soldering, reliable corrosion protection, or a non-toxic finish for food contact. It is ideal for electrical connectors, busbars, fasteners, and food processing equipment. We offer both bright and matte tin finishes, allowing for specific aesthetic and functional requirements, such as whisker mitigation.

Our Tin Plating Capabilities: Precision and Performance

We offer precise Tin Plating services, ensuring a uniform and high-quality deposit for your components.

  • Exceptional Solderability: Tin provides an excellent surface for soldering, creating strong, reliable electrical connections.
  • Corrosion Protection: Forms an effective barrier against rust and corrosion, extending the lifespan of components.
  • Electrical Conductivity: Offers good electrical conductivity, maintaining efficient current flow.
  • Ductile and Malleable: The soft nature of tin allows for post-plating forming, crimping, or bending without cracking the coating.
  • Non-Toxic and Food Safe: Pure tin is non-toxic, making it suitable for food processing equipment and medical applications.
  • Whisker Mitigation (Matte Tin): Matte tin finishes are known to be more resistant to tin whisker growth, a critical consideration for electronic reliability.
  • Bright and Matte Finishes:
    • Bright Tin: Provides a lustrous, decorative finish, often chosen for its aesthetic appeal.
    • Matte Tin: Offers a duller, non-reflective finish, preferred for its anti-whisker properties and consistent solderability.
  • Rack and Barrel Plating: We accommodate both rack and barrel plating methods to suit various part sizes and production volumes.
  • Thickness Control: We achieve precise plating thicknesses to meet specific design and performance requirements.
  • In-house Quality Verification: We conduct solderability testing and thickness analysis using X-ray fluorescence to ensure coating integrity and compliance.

Properties of Tin Plating:

Tin plating imparts several key properties that enhance the performance and utility of components:

  • High Solderability: Ensures strong and reliable connections in electronic assemblies.
  • Corrosion Resistance: Provides effective protection against atmospheric and chemical corrosion.
  • Non-Toxic: Safe for contact with food and beverages.
  • Ductility: Allows for subsequent forming without compromising the coating.
  • Good Conductivity: Maintains electrical continuity for various applications.
  • Low Friction: Offers inherent lubricity, useful for sliding parts.

Applicable Specifications We Adhere To:

Our Tin Plating processes consistently meet or exceed crucial industry standards, ensuring the quality and performance of your components. We regularly process to:

  • ASTM B545 (Standard Specification for Electrodeposited Coatings of Tin)
  • MIL-T-10727 (superseded by ASTM B545, but often referenced)
  • AMS 2408 (Tin Plating)
  • And various customer-specific requirements.

Typical Tin Plating Applications:

Tin plating is vital for numerous applications across various industries:

  • Electronics: Used extensively for connectors, terminals, busbars, wire leads, and printed circuit board components due to its solderability.
  • Food Processing Equipment: Applied to food-grade containers, components, and utensils for its non-toxic and corrosion-resistant properties.
  • Automotive Industry: Protects electrical contacts, battery terminals, and various fasteners.
  • Fasteners: Enhances corrosion resistance and ensures consistent torque-tension properties for bolts, nuts, and washers.
  • Busbars and Conductors: Provides a low-resistance, corrosion-resistant surface for power distribution.
  • Hardware and Tools: Offers corrosion protection and a desirable finish.
