Tin plating is one of the most widely used metal finishing solutions across industries. Known for its excellent solderability, corrosion resistance, and cost-effectiveness, tin is ideal for protecting components in demanding environments without compromising performance or conductivity.
At The Lindgren Group, we specialize in precision tin plating services for clients in electronics, aerospace, defense, medical devices, and industrial manufacturing. Our plating capabilities are engineered to meet industry-specific requirements and ensure high-performance finishes across a wide range of materials and components.

Why Choose Tin Plating?

Tin plating is often chosen for its versatility and functionality across a wide range of applications. Depending on your performance needs, tin can be plated in either bright, matte, or semi-bright finishes.

Key Benefits of Tin Plating

  • Excellent solderability
  • Strong corrosion resistance
  • Low contact resistance
  • Non-toxic and RoHS-compliant
  • Cost-effective alternative to precious metals
  • Prevents whisker formation with proper underplating
  • Provides good coverage and ductility
  • Acts as a barrier layer against oxidation

Our Tin Plating Capabilities

At The Lindgren Group, we tailor our tin plating process to meet the unique technical needs of each customer. We provide:
  • Bright Tin Plating – Highly reflective with excellent solderability; commonly used in electronics
  • Matte Tin Plating – Dull finish with low porosity; offers enhanced corrosion resistance and minimizes tin whiskers
  • Semi-Bright Tin Plating – A balanced finish between luster and performance
  • Pure Tin and Tin Alloy Options – Customizable for application-specific requirements
  • Rack, Barrel, and Vibratory Plating Options – Scalable for part size and production volume
  • Nickel Underplating – Prevents base metal diffusion and enhances finish performance
  • Selective Plating – For parts requiring plating on specific areas only
  • Anti-Tarnish and Post-Treatment Options – To extend shelf life and stability
Our finishes are compatible with substrates including copper, brass, steel, stainless steel, and aluminum (with underplating). We can plate tin to thicknesses ranging from 50 microinches to over 1 mil, depending on the application.

Tin Whisker Mitigation

One of the challenges with tin plating is the potential for tin whisker growth, which can lead to electrical shorting in microelectronics. At The Lindgren Group, we mitigate whisker formation by:
  • Using matte tin with controlled grain structure
  • Applying nickel or copper underplates
  • Controlling bath chemistry and plating conditions
  • Offering post-plate annealing or heat treatments when needed
We work directly with your engineering teams to ensure the finish meets all long-term performance standards.

Certifications and Industry Standards

Our tin plating services are designed to comply with rigorous industry and military specifications, including:
  • ASTM B545 – Standard Specification for Electrodeposited Tin Coatings
  • MIL-T-10727 – Tin plating for military electronics
  • IPC J-STD-001 – Requirements for soldered electrical assemblies
  • RoHS and REACH Compliance – Lead-free and environmentally responsible processes
We maintain thorough process control, inspection protocols, and documentation to meet or exceed aerospace, defense, and medical industry expectations.
