Professional Surface Finish for High-Performance Circuit Boards
Immersion Silver (ImAg) PCB finish delivers exceptional electrical performance and reliability at a fraction of the cost of premium alternatives like ENIG (Electroless Nickel Immersion Gold). This advanced surface treatment provides excellent conductivity and solderability while maintaining budget-friendly pricing for medium to high-volume production runs.
Key Benefits:
- Superior Electrical Performance – Ultra-low contact resistance and excellent signal integrity for high-frequency applications
- Outstanding Solderability – Creates strong, reliable solder joints with excellent wetting properties
- Cost Efficient – Significantly more affordable than gold-based finishes while delivering comparable performance
- Fine Pitch Compatible – Ideal for dense component layouts and BGA applications with pitches down to 0.4mm
- Flat Surface Profile – Smooth, uniform coating perfect for press-fit connectors and test probes
- Lead-Free Compatible – Fully compliant with RoHS regulations and lead-free soldering processes
Applications: Perfect for consumer electronics, telecommunications equipment, automotive modules, industrial controls, and any application requiring reliable electrical connections without premium finish costs. Particularly well-suited for products with moderate shelf life requirements and controlled storage conditions.
Technical Specifications:
- Coating thickness: 5-18 microinches
- Shelf life: 6-12 months (proper storage)
- Operating temperature: -55°C to +150°C
- Surface roughness: <50 microinches Ra
Why Choose Immersion Silver? When your project demands excellent electrical performance and reliable assembly but budget constraints make gold finishes impractical, Immersion Silver provides the perfect balance of quality and cost-effectiveness. Get professional-grade results without the premium price tag.
Ideal for prototypes, medium-volume production, and cost-sensitive applications where performance cannot be compromised.
