Nickel plating for hybrid connectors
Electrolytic nickel at SM Finishes is the diffusion barrier under gold or tin, a wear surface on shells and latches, and a corrosion layer on steel fasteners. When the drawing calls it, we plate to ASTM B689 / QQ-N-290. ISO 9001:2015 and AS9100:2015 from Machohalli, Bengaluru.
Nickel on hybrid connectors is rarely “just decorative”. Bright or satin appearance can be specified, but thickness and whether nickel is final or undercoat come from the print. Lead time is quoted with the full stack and whether first-article or PPAP is required.
Why Our Nickel Plating Stands Out
Our nickel plating process is controlled to achieve optimal thickness, adhesion, and surface uniformity. Using advanced technology and rigorous inspection, we ensure coatings meet the exact requirements of your application, whether functional, decorative, or both.
- Optimized thickness
- Consistent microstructure
- Resistance to chemical attack
- Superior adhesion
- Stable conductivity
- Temperature variations
Nickel plating with SM Finishes offers versatility and performance that few finishes can match. It delivers protection in harsh environments, extends the life of critical components, and provides a premium aesthetic finish that elevates product value.
Precision & Craftsmanship
Each nickel plated component passes through meticulous cleaning, preparation, and controlled plating stages. Our team of skilled technicians ensures consistent results that meet international quality benchmarks for appearance and durability.
Applications
Nickel plating is widely used for its balance of performance and aesthetics, making it suitable for multiple industries.
Electrolytic nickel process
We plate nickel on copper alloys, steel and other prepared metals used in aerospace, automotive and electronics connectors. A copper undercoat is used when levelling or adhesion needs it. Thickness is verified on Fischer XRF. For uniform coverage on complex internal geometry, electroless nickel is the better chemistry — that is a different page and tank.

Applications on hybrid connector hardware
Signal contacts: nickel under gold. Solder tails: nickel under tin. Shells and latches: nickel as wear and corrosion. Fasteners: nickel as a standalone corrosion layer when gold is not required. Japanese and Taiwanese drawings often stack nickel + gold or nickel + tin — send the full stack-up so we quote one process flow.
Defence and aerospace lots can carry travellers suitable for AS9100 review. Automotive lots can add PPAP.
Barrel vs rack nickel
Rack nickel when subsequent gold thickness must be held on contacts. Barrel nickel for bulk fasteners and small hardware. Mixed-metal assemblies may also need passivation or conversion coating on adjacent parts — sequence those chemistries so one bath does not attack the other alloy.
