What do I need to change to lead free hand soldering pcb's (about 15 seats)?
Any advice gratefully received.

Baphomet said:I'm not sure why you would want to. Lead free will probably raise the
melting point and to compensate, you would either have to use lighter guage
or flatten it with a hammer before soldering. Since it doesn't sound like
you have much soldering to do, I wouldn't worry about it unless you are lead
allergic.

R.Lewis <h.lewis- said:For 15 seats read 15 people hand soldering components into pcb's (Yes we
also use flow soldering ).
We need to change from SnPb solders because of customer demand at this time,
and because by July 2006 we will have no choice.

soldering will be unacceptable .
They are particularly concerned about the possibility of tin whiskers
forming. Any knowledge out there.

For defence and automotive applications, the behaviour of the solders atwrote (in said:Both of these articles discuss tin whisker growth from now obsolete
matte tin plating, not from lead free solders which are of course
considerably different and most of which are not known to be subject
to tin whisker growth. They would seem to be completely irrevelant to
the subject of lead free soldering!

Almost all of what I have seen published on lead-free soldering has
been for automated soldering only (reflow and wave primarily).
Likewise, most of the new lead free alloys seem to be availible in
paste or bar only.
Apparently not if the government defense industry is currently proposing
banning lead free soldering because of tin whiskers. I really don't know
first hand because I have been out of the military industrial complex since
about '77. Back then, lead free wasn't even a consideration in the mind's
eye of the most politically correct ideologue.
