Tin-Lead (ASTM: B 579) Plating
Specialized Tin-Lead Plating for Important Applications
Is your business experiencing solderability challenges, whisker growth problems, or premature corrosion of electronic components? Many manufacturers face production and reliability issues with components lacking the optimal surface properties that properly applied tin-lead plating provides.
At Nobert Plating, we deliver precision tin-lead plating services for businesses requiring exceptional solderability, corrosion resistance, and whisker mitigation. From electronic connectors to specialized hardware, our tin-lead solutions provide outstanding performance across diverse industrial applications.

The Technical Value of Professional Tin-Lead Plating
Standard plating services often fail to achieve the precise deposit characteristics required for high-reliability components. Your products demand a plating partner with specialized expertise in tin-lead alloy deposition.
Our tin-lead plating services address several important manufacturing needs:
- Outstanding solderability for electronic assembly
- Extended component shelf life before assembly
- Whisker growth mitigation for high-reliability applications
- Corrosion protection in various environments
- Low contact resistance for electrical connections
- Compatibility with modern manufacturing processes
With extensive tin-lead plating expertise, our technical team balances performance requirements with regulatory compliance to deliver plated components that excel in your most demanding applications.
Tin-Lead Plating Process Advantages

Alloy Composition Control
Our processes maintain tight control of tin-lead ratios, typically 60/40 or 63/37, to meet your exact specifications.

Solderability Performance
Exceptional wetting characteristics support reliable solder joint formation in electronic assembly.

Whisker Mitigation
Lead content effectively prevents the tin whisker growth that can cause catastrophic failures in pure tin coatings.

Low Melt Point
The eutectic properties of tin-lead provide appropriate melt temperatures for electronics assembly.

Thickness Precision
Advanced process controls maintain consistent deposit thickness to meet your specifications.

Regulatory Compliance
We maintain clear documentation of exemption status for RoHS-restricted applications where tin-lead remains the optimal technical solution.

Frequently Asked Questions About Tin-Lead Plating
We typically offer 60/40 (60% tin, 40% lead) and 63/37 (eutectic) compositions, with custom alloy ratios available for specialized applications.
Most common metals can be tin-lead plated, including copper, brass, steel, and nickel alloys. Material compatibility assessment is part of our quality process.
Standard applications range from 0.0002" to 0.0005", with capability for custom thicknesses based on specific requirements.
Tin-lead offers outstanding whisker growth resistance and often better solderability than pure tin, making it preferred for high-reliability applications where RoHS exemptions apply.
Tin-lead contains lead and is typically not RoHS compliant. It remains available for applications with specific exemptions such as military, aerospace, and certain medical devices.
Our tin-lead plating processes conform to ASTM B579, MIL-P-81728, and other industry specifications depending on your requirements.
Under proper storage conditions, tin-lead plated components typically maintain excellent solderability for 12+ months, significantly longer than many alternative finishes.
Yes, tin-lead plated components can be assembled using lead-free solders, though process parameters may require adjustment to accommodate the mixed metallurgy.
Minimal discoloration may occur with extended storage, but this rarely affects functional properties such as solderability.
We employ X-ray fluorescence for composition and thickness verification, solderability testing per industry standards, and visual inspection for coverage and appearance.
