NIPLATE® LINK
Electroless Nickel for Busbars and Solderable Components

Name: NIPLATE LINK - Electroless Nickel for Busbars
Brand: Niplate
Availability: InStock

Niplate Link is an electroless nickel plating treatment, covered by a patent application, specifically designed for electrical and interconnection components such as copper busbars, connectors and parts intended for soldering and brazing.

The coating provides a solderable, corrosion-resistant and long-term stable surface, significantly reducing the risk of surface oxidation that could compromise joint quality.

Thanks to the high uniformity and strong adhesion of the deposited layer, Niplate Link improves the reliability of electrical connections in power distribution systems and reduces failures caused by joint defects.

It is ideal for busbars and electrical components used in electric vehicles, inverters, battery packs and power converters, where connection reliability and long-term durability are critical requirements.

In addition, due to its excellent corrosion resistance, it can also be used in water-cooled circuits, preserving surface passivation and protecting the base material.

Compared to traditional electroplated solutions, Niplate Link offers a repeatable, cost-effective process free of precious metals, optimized for high-productivity industrial manufacturing, particularly for components with complex geometries.

Copper busbars treated with Niplate Link to ensure solderability and corrosion resistance

PROPRIETARY TECHNOLOGY

Niplate Link is a technology developed in-house by Micron, protected by a patent application, ensuring uniqueness and a strong competitive advantage in the e-mobility sector.

SOLDERABLE SURFACE

Coating engineered to maintain excellent solderability. Compatible with tin-based and aluminum brazing alloys.

CORROSION RESISTANCE AND DURABILITY

The alloy maintains a stable, oxide-free surface even after long-term storage, ensuring consistent solderability over time.

CHEMICAL AND CORROSION RESISTANCE

Excellent resistance to corrosion and humid or saline environments. Copper components withstand over 1000 hours in NSS testing (ISO 9227) with coating thickness ≥ 5 μm.

HIGH PERFORMANCE IN E-MOBILITY

Ideal for electric vehicle busbars, inverters (IGBT) and battery systems: prevents the formation of brittle intermetallic compounds (e.g. Al-Cu) and enhances joint reliability.

UNIFORM THICKNESS

Uniform deposition even on complex geometries, without the edge thickness buildup typical of conventional electroplating processes.
