Conductive adhesives vs. Lead-free solders.

Hi Bob,

I know that that conductive adhesives have been considered as a lead relacement in the past, but have been ruled out due to cost and other process issues (surface tension etc..) IBM has extensive development data on the topic and had come up with some pretty good adhesives in doing so. My question is: Do you feel or have you heard of any "real" viable candidate ahesive that might take the place of leaded solder for SMT process? Your response is appreciated. Thanks.
