Following from the EMPF HelpLine in Indianapolis 317.226.5616; prepared by

Most of the recent problems with Pd plated leads have stemmed from the 
conversion to water soluble fluxes.  Some water soluble fluxes seem to work 
well, others don't.  If you have specific solderablity issues, or want the 
latest information on the optimal processing techniques, TI has an 
individual who trouble-shoots Pd solderability issues: Doug Romm -

I'm new on the forum so forgive this question but: Is anyone
experiencing problems with palladium plated IC leads.  My previous
experience a couple of years ago was that decent reflow using standard
profiles (max T 215-220C) resulted in poor quality soldering of the
offending ICs.  I am now faced with a choice of using such parts again
and am somewhat nervous.
