Frequently Asked Questions

What is tin plating and how does it work?

Tin plating is an electrochemical process that deposits a layer of tin onto a metal surface. Parts are immersed in a plating bath and exposed to direct current, creating a uniform, protective coating.

What are the benefits of tin plating?

Tin plating improves corrosion resistance, enhances solderability, and provides reliable electrical performance. It is widely used in electronics, aerospace, and industrial applications.

What specifications does Rayco meet for tin plating?

Rayco Metal Finishing performs tin plating in accordance with ASTM B545 and supports additional industry standards to meet strict compliance requirements.

What types of parts are best suited for tin plating?

Tin plating is ideal for components that require solderability and corrosion protection, including electrical connectors, aerospace parts, medical devices, and precision-machined components.

How do I know if tin plating is the right process for my project?

If your application requires corrosion resistance and strong solderability for electrical performance, tin plating is often the best solution. Rayco can help determine the appropriate specification for your project.
