Aluminum-Copper Foil Nickel-Tin Plating Service ATOMFAIR®

The nickel underlayer thickness must not exceed 0.1 μm to ensure proper adhesion and uniform tin plating. The tin plating thickness is customizable between 0.5 and 5 μm and requires confirmation of foil condition, width, and layer thickness tolerance.

• Substrate Compatibility: The supplied foil must be aluminum-copper alloy to be compatible with the nickel underlayer and tin plating process.
• Nickel Thickness Limit: The nickel underlayer thickness is limited to a maximum of 0.1 μm to maintain process stability.
• Tin Thickness Range: The tin plating thickness must be specified within the customizable 0.5 to 5 μm range.
• Foil Condition Verification: The supplied foil condition, including width and surface quality, must be confirmed to ensure proper plating adhesion.
• Thickness Tolerance Confirmation: Layer thickness tolerances must be agreed upon during specification confirmation to meet application requirements.

The service requires detailed specification of the incoming substrate and target plating parameters. Follow these steps to ensure correct processing and quotation.

Required Equipment: Technical sales inquiry or quotation request form

1. Verify Substrate Material
   Confirm that the supplied foil is aluminum-copper alloy suitable for nickel underlayer and tin plating.
2. Specify Plating Thicknesses
   Set the nickel underlayer thickness to ≤0.1 μm and the tin plating thickness to a value between 0.5 and 5 μm based on application requirements.
3. Provide Foil Dimensions and Condition
   Include the foil width, condition, and required layer thickness tolerance in the specification confirmation.
4. Submit Quotation Request
   Send the substrate details, nickel thickness, tin thickness, width, and quantity to the technical sales team for quotation.

This incoming foil plating service applies a ≤0.1 μm nickel underlayer followed by a customizable 0.5–5 μm tin layer on supplied aluminum-copper foil, enabling tailored surface modification for battery current collector or interconnect applications.

Positive

• Customizable tin thickness range: Tin plating thickness is adjustable from 0.5 to 5 μm, allowing the user to tune the coating for specific electrochemical or soldering requirements without changing the base substrate.
• Controlled nickel underlayer thickness: The nickel underlayer is specified at ≤0.1 μm, providing a thin diffusion barrier and adhesion layer between the aluminum-copper foil and the tin coating, which can improve long-term interface stability.

Trade-offs

• Requires supplied foil confirmation: The service is limited to incoming aluminum-copper foil; the user must confirm the foil condition, width, and layer thickness tolerance before processing, adding a coordination step to procurement.
• Customization requires quotation: Target tin thickness and substrate details must be specified and confirmed via quotation, meaning the final coating parameters are not available as off-the-shelf options and require pre-order technical discussion.
