Expert Panel Responses

I would go withpure tin as it would be the most conductive and also cut out the risk of issueswith different plating thickness on tin versus lead, the solder joint is a mixof metals so areas will be tin or lead rich. How ever I have to ask why wouldyou nickel plate over a solder joint?
