If you're talking Alpha Level process (?):
1
good solderability (as HASL(even no cleans bite well) , planarity .
2
they don't hold as well in store as NiAu (say use within 6 months sealed)
3
very sensitive (more than osp!) on touch ; the finger acid breaks the seal
and than the silver tarnishes very fast.

4
doesn't like multipass (obviously) ; experiment prior to double side process
.

Hey Guys,
Got a question. I have to start running some PCBs that have Organo-Metallic
Silver Immersion for plating. What are the pros and cons? Will I have to use
OA solder paste? Any information will be beneficial.
