December 17, 2024 - San Mateo, California - San Francisco Circuits, a premier
provider of leading edge technology printed circuit boards, has published a new
article on the
Immersion Silver Surface Finish process, also known as immersion Ag. It is an
RoHS compliant (lead-free) PCB surface finish offering exceptional flatness and
cost efficiency. This surface finish is particularly well-suited for fine-pitch
components and can replace
Immersion Gold over
Electroless Nickel (ENIG) in many applications.
Unlike ENIG, Immersion Silver applies directly to copper without requiring a
diffusion barrier. It's an excellent choice for applications that must avoid magnetic
materials in the PCB.
Key Benefits of Immersion Silver
- Planar and Reworkable: Ideal for fine-pitch designs and surface-mount technology
(SMT).
- Cost-Effective and Stable: Combines affordability with high stability.
- RoHS Compliant: Meets environmental and regulatory standards.
- Great Solderability: Ensures reliable connections and easy processing.
Applications of Immersion Silver
This surface finish is widely used in:
- EMI Shielding
- Aluminum Wire Bonding
- Membrane Switches
- Very Fine Traces
While Immersion Silver offers several advantages, its sensitivity to contaminants
and susceptibility to tarnishing make proper handling and storage critical. Choosing
a qualified board house is essential to maintain quality and performance.
