Precious Plate delivers specialized substrate and surface treatment solutions that enhance component performance, extend service life, and maintain metal brilliance. Our Tarniban-Evabrite technology is engineered for industries where both appearance and functional reliability matter—ensuring that every surface remains protected from oxidation and corrosion, even under demanding operational conditions.
When metals must stay bright, solderable, and efficient under environmental and operational stress, Precious Plate’s Tarniban-Evabrite treatment provides a dependable solution. This advanced anti-tarnish and protective finish supports a range of precious and base metals used in electronic contacts, connectors, and precision components. By combining decades of plating experience with ongoing materials innovation, Precious Plate delivers measurable improvements in product appearance, reliability, and function.
From connector manufacturers to semiconductor packaging suppliers, customers rely on Tarniban-Evabrite to maintain consistent visual appeal and reliable electrical performance. The process reduces downstream maintenance, component waste, and rework—saving both time and cost while ensuring quality assurance from batch to batch.
Prevents discoloration, oxidation, and tarnish over long-term storage or exposure.
Maintains clean, active surfaces that facilitate consistent wetting and joining.
Minimizes the resistance increases commonly associated with untreated metal oxidation.
Adapted for gold, silver, and palladium finishes to meet exact industry requirements.
Designed with chemistry and process controls meeting strict sustainability benchmarks.
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.
Components are cleaned and pretreated to remove organic and inorganic contaminants, ensuring full adhesion of subsequent layers.
Substrate properties are optimized for protection, whether copper, nickel, or alloy.
Controlled selective plating or reel-to-reel application deposits the required finish thickness uniformly.
An anti-tarnish film is applied using immersion or controlled flow methods to achieve uniform coverage.
Thickness, adhesion, and corrosion-resistance testing confirm compliance with customer and industry standards.
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
When considering advanced antitarnish treatments, customers often have practical questions about specifications, compatibility, and scalability. The following frequently asked questions address the most common technical and purchasing considerations.
Choosing Precious Plate means partnering with a company that not only delivers quality surface finishes, but also provides process transparency and technical collaboration to meet every project specification.
It is optimized for silver, gold, and palladium finishes and can be effectively applied over nickel or copper underplates depending on component design.
No. The coating is microscopically thin and designed to maintain conductivity and solderability without increasing contact resistance.
Our reel-to-reel systems support both small development runs and high-volume continuous production. Lead times vary based on lot size and metal type.
All Tarniban-Evabrite treatments are supported by inhouse testing to IPC and ASTM specifications, with full documentation available upon request.
Yes. Our processes comply with RoHS and REACH regulations, using nonhazardous chemistries and controlled waste management systems.
Every component we treat reflects our commitment to engineered precision and surface integrity. Precious Plate’s Tarniban-Evabrite service combines science, craftsmanship, and data-driven verification—so your products look better, perform longer, and inspire customer confidence.
