Over 8 years of tin plating expertise across multiple substrates
Tin plating provides excellent electrical conductivity, solderability, and mild corrosion resistance. With over 8 years of dedicated tin plating experience at Technocrats India, we plate across a range of substrates including copper, brass, steel, and nickel-plated substrates — for connectors, bus bars, PCB contacts, and precision stampings serving the automotive and electronics industries.
Our tin plating is available in bright and matte finishes, with coating thickness calibrated precisely using XRF measurement. Both barrel and VAT (rack) processing are offered, allowing us to handle high-volume connector stamping batches and large precision assemblies alike. Every batch is verified for thickness and appearance before release.
Key benefitsSuperior conductivity
Tin's low contact resistance makes it the standard coating for electrical connectors, terminals, and bus bars.
Excellent solderability
Tin surfaces accept solder reliably, making them ideal for PCB contacts, leads, and through-hole components.
Bright and matte finishes
Both bright and matte tin are available, each offering different surface characteristics for different applications.
Barrel and VAT rack
High-volume small parts via barrel; precision or large components via VAT (rack) — both available at TCI.
Tin plating is used primarily to improve solderability and electrical conductivity, and to provide mild corrosion protection. Common applications include electrical connectors, terminals, PCB contacts, bus bars, and precision stampings in automotive and electronics industries.
We plate tin onto copper, brass, steel, and nickel-underplated substrates — covering most connector and electronics applications. Copper and brass are the most common base metals for connector stampings.
Coating thickness is measured using non-destructive XRF analysis on every production batch. Results are documented and available for traceability. Thickness targets and tolerances are set per customer specification or applicable standards.
