When you compare with ENIG or HASL PCB,Immersion Silver Surface Finish PCB is very new PCB type.
So we must introduce this very care full.And we will introduce several points about Immersion Silver PCB below:
-The difinition of Immersion Silver Plating PCB
-Immersion Silver Surface Finish Comparer with ENIG and HASL
-Hight performance of Immersion Silver Surface Finish
-The Packaging of Immersion Silver PCB

The difinition of Immersion Silver Plating PCB
Immersion Silver Plating is a surface plating technology used for Printed Circuit Boards,it is deposited directly on the copper surface by a chemical displacement reaction and is available in the industry all co-deposit and organic anti tarnish with the immersion silver. This reaction is fast and does not require the relatively high temperatures of ENIG
Immersion Silver Surface Finish Comparer with ENIG and HASL
Immersion Silver finish (also referred to as ‘IAg’), provides a ROHS compliant finish for printedcircuit boards (pcbs), but is thinner than ENIG or traditional HASL finish.
Hight performance of Immersion Silver Surface Finish
Immersion silver offers better performance and superior finishes for final
finishes on PCBs, and has been generally favored by clients.
That is the reason why more and more electronic company choose Immersion Silver PCB.

The Packaging of Immersion Silver PCB
Handling, packaging, and storage are the most challenge in the production of PCBs. It have to be more carefully when immersion silver are done. Packaging of immersion silver printed circuit boardis very important, it has to minimize contact of the surface with the environment and to ensure all materials used in the packaging and during storage are sulfur free.
