One of our suppliers is 'proposing' a new lead free finish which he says
will solder perfectly well with 'normal' SnPb solder as well as Lead Free.

The finishes they are proposing are SnAg, SnBi and SnCuAg.  my question is,
Does anyone have experience with using these finishes through a normal
process and are there any 'pitfalls' top look out for.

There is a lot of talk about total Pb free processes but what about the
interim - are the new finishes 'backwards compatible'!!

Thanks in anticipation of everyone's responses.

Neil
