Are currently investigating a change of solder paste for various reasons and are considering a move from 63/37 to using 2% silver solder paste for increased long term reliabilty of solder joints with gold finish PCBs and to further reduce reflow temps as we are often place temp sensitive components.
However we also have some pcbs supplied by customers that are an imersion silver finish. Does anyone know of any issues with to much silver being present in these joints?
Are there any other issues with 62/36/2Ag that I should be aware of?
