Sn/Pb paste with SAC plating

Sn/Pb paste with SAC plating | 21 October, 2004

I have a component manufacturer that is using Sn/Ag/Cu plating on chip caps and resistors. Does anyone have any information on compatability with Sn/Pb paste. Are any changes in profile required? Is the reliability of the solder joint at risk?

While it's not exactly what you asked, it's similar. Here is a thread from the fine SMTnet Archives from a couple of weeks ago, where we spoke about the topic of mixed lead-free solder with components that have lead-bearing solderability protection: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=30307
