San Francisco Circuits highlights that Immersion Silver, or immersion ag, is a lead-free (RoHS compliant) surface finish for Printed Circuit Boards (PCBs) that provides excellent flatness and cost-effectiveness. discover more >>
This coating is notably beneficial for fine-pitch components and can often serve as a substitute for Immersion Gold over Electroless Nickel (ENIG) in various applications.
In contrast to ENIG, Immersion Silver is applied directly onto copper without the need for a diffusion barrier, making it an ideal option for applications that require the exclusion of magnetic materials in the PCB.
Advantages of Immersion Silver
- Flat and Reworkable: Perfect for fine-pitch designs and surface-mount technology (SMT).
- Affordable and Reliable: Merges cost-effectiveness with high stability.
- Environmentally Compliant: Adheres to RoHS standards.
- Excellent Solderability: Guarantees dependable connections and straightforward processing.
Uses of Immersion Silver
This surface finish finds extensive submission in:
- Electromagnetic Interference (EMI) Shielding
- Bonding with Aluminum Wires
- Membrane Switch Applications
- Very Fine Traces
despite its numerous benefits, Immersion Silver is sensitive to contaminants and prone to tarnishing, making careful handling and storage essential.Selecting a reputable boardhouse is crucial to ensure quality and performance.
