How is the heavy/fast drossing characteristic of some lead free solders (
e.g. SnAgCu) dealt with in process environment of wave soldering.

 Doesn't the heavy dross effect the quality of solder tremendously with the
added surface tension?

 What can be done to prevent this?  I know that a trace of phosphurus can
be added into the solder to have effect on the drossing, but I would like
to know what other people in Industry know about leadfree in production.
