Enhanced solderability

Maintains clean, active surfaces that facilitate consistent wetting and joining.

Optimized conductivity

Minimizes the resistance increases commonly associated with untreated metal oxidation.

Customizable application

Adapted for gold, silver, and palladium finishes to meet exact industry requirements.

Environmentally responsible

Designed with chemistry and process controls meeting strict sustainability benchmarks.

How the Tarniban-Evabrite Process Works

Preserving noble metal finishes requires control, consistency, and chemical precision. Precious Plate’s Tarniban-Evabrite process integrates protective chemistry with our proprietary substrate preparation and plating systems to deliver consistent performance.

Through this controlled workflow, customers receive treatment results that are repeatable, measurable, and traceable—critical for industries requiring validated processes like electronics, defense, and telecommunications.

1.) Surface Preparation

Components are cleaned and pretreated to remove organic and inorganic contaminants, ensuring full adhesion of subsequent layers.

2.) Base Metal Conditioning

Substrate properties are optimized for protection, whether copper, nickel, or alloy.

3.) Precious Metal Deposition

Controlled selective plating or reel-to-reel application deposits the required finish thickness uniformly.

4.) Tarniban-Evabrite Application

An anti-tarnish film is applied using immersion or controlled flow methods to achieve uniform coverage.

5.) Post-Treatment Verification

Thickness, adhesion, and corrosion-resistance testing confirm compliance with customer and industry standards.

Case Study

Extending Connector Lifespan in Harsh Environments

A global electronics manufacturer faced recurring issues with contact oxidation and performance degradation in outdoor communication assemblies. Their engineering manager sought a durable surface finish that would maintain solderability and electrical integrity after prolonged environmental exposure.

By implementing Precious Plate’s Tarniban-Evabrite treatment over a silver and nickel substrate, the manufacturer reduced visible tarnish formation by over 85% and maintained contact resistance values within acceptable limits after 1,000 hours of humidity testing. Production yield improved, maintenance frequency dropped, and the product achieved longer field life expectancy

“Switching to Precious Plate’s Tarniban-Evabrite solution helped us secure consistent performance across multiple product lines. It’s the reliability and technical support that made the difference.”
