There have been many comments on this subject but few asking why move away
from HASL or do you not want to use tin/lead or lead-free HASL?

There are lots of high end users that have found good PCB shops who are able
to provide a good repeatable surface finish. Its key to work with your
supplier and lead-free works well for solderability and assembly yields.

Subject: [TN] ENIG White paper

Dear Technetters,
 
I am trying to locate a white paper on the pluses and minuses of ENIG
that I think was circulated through the IPC. Can anyone point me to that
document? We are considering changing from HASL to ENIG for our SMT
designs and want to see what we should look for or anticipate.
Thanks,
Dave Connitt
