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 . -----Original Message----- From: Carl Ray [mailto:[log in to unmask]] Sent: Saturday, 11 September 1999 21:41 To: [log in to unmask] Subject: [TN] SMOBC Explain 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.
