Hello Scott,
I believe the paper Chada. S., Bradley. E., "Investigation of Immersion
Silver PCB Finishes for Portable Product Applications", had information on
using Imm Ag for keypads and the results were acceptable. Can't find my copy
at the moment but still looking.
Regards,
Graeme Stewart

Subject: [LF] Immersion Silver and Conductive Carbon Ink
Fellow list persons,
I have a printed circuit board used in a remote control unit. We changed the
solder plating on the board to immersion silver for RoHS compliance.
Our fabricator is having a problem getting the conductive carbon ink to
stick to the immersion silver. Is anyone aware of this type of problem?
We are trying to figure out if we just have a vendor problem or is there
some issue with the immersion silver and conductive carbon ink combination.
Any suggestions as to changes or corrective actions?
As always, thank you in advance for your comments.
