Without knowing too much about the chemistry of solder, things to consider:
Would this change the intermetallic capabilities of the solder connections?
What is the conductor finish on your bare boards? Would they be compatible
with this change?
Soldering equipment in your factory. Would you need to change some of it?
What about dwell times and temperature? Would this change require
retraining of your solderers?

Subject: [TN] lead free solder

Hi all,
One of our engineers suggested that we throw away all of our spools of
tin/lead solder (citing health concerns) creating a lead free office. He
suggested we use "kester saf-alloy" for hand soldering.
I'd like to throw out some questions:
What is the current line on human safety using tin/lead solder (hand
soldering, no wave solder here)?
Does lead easily absorb into the skin?
Does some become airborne with flux fumes?
What general reliability or process concerns does the industry have about
using lead free solders?
Your info is appreciated.
