Hi Ofer,
Without knowing which LF-solder you talk about, no specific advise can be
given. Coatings themselves are not a real problem.
However, when LF-solders will be used and most LF-solders in the running
require 35 to 40°C higher refllow temperatures--or reductions in belt speeds;
thus, yes you need to think about process changes. Workmanship is about the same/
reliability effects have not fully determined--and will not be for some time
to come.
You may be interested in the upcoming conference IPC/Soldertec Global
Conference on Lead Free Electronics in Brussels on June 10 and my workshop
Reliability Issues for Lead-Free Soldering.
Regards,
Werner Engelmaier
