At Fast Turn PCB, we specialize in delivering cutting-edge surface treatment solutions that enhance the reliability and performance of your printed circuit boards (PCBs). One of our core competencies is Gold Finger plating, powered by the Electroless Nickel Immersion Gold (ENIG) process. This technology is essential for PCBs used in telecommunications, automotive electronics, medical equipment, and industrial control systems.
What Are Gold Fingers?
Gold Fingers are the gold-plated edge connectors found on PCBs. These serve as critical contact points between PCBs and their mating connectors, and must offer superior durability, conductivity, and corrosion resistance. Fast Turn PCB uses industry-proven ENIG surface finish to ensure every gold finger meets IPC standards and rigorous inspection criteria, such as:
No visible scratches or gouges
No discoloration or oxidation
No plating delamination (peel test compliant)
No surface contamination (e.g., adhesive or residue)
No dents or pits, especially in critical contact areas
No exposed copper
Why ENIG for Gold Fingers?
1.Excellent Solderability and Bonding
Our ENIG process creates a uniform gold layer over a nickel base, resulting in:
Strong, reliable solder joints
High production yield with fewer soldering issues
Consistent performance across batches
2.Exceptional Corrosion Resistance
The nickel layer acts as a barrier to oxidation, while the gold layer provides additional protection from humidity, moisture, and environmental exposure—perfect for aerospace, military, and medical electronics.
3.Reliable Electrical Conductivity
Gold offers one of the highest levels of electrical conductivity. Our ENIG-plated gold fingers ensure:
Stable signal transmission
Minimal signal loss in high-frequency circuits
High performance in data-intensive applications
4.Flat, Clean, and Professional Surface Finish
The ENIG process ensures a smooth, bright, and flat finish that:
Supports automated assembly
Enhances insertion/removal durability
Reflects the high-quality manufacturing standard of Fast Turn PCB
