If you want reliability, don't use any solder but weld the components
to the PCB.

Come back after you have studied metallurgy a while, idiot.

In this instance I have to agree with your comment.

Ditto....

Most of you arguing the virtues of lead free are just trying to tell us all
the sky is green. You are just arguing to argue. Were these processes really
any good, they would have become the "norm" in an open market.

Lead Free part DO fall off. If you process them with lead based solder in
assemblies that have both kinds of parts, they don't wet correctly under
older profiles. Lesser issues appear with complete lead free assemblies in
this area, but using MORE energy and EXPENSIVE equipment, they may be
resolved to some extent. But in the end, current alloys used will never
EQUAL tin/lead.

Can leadfree processes be optimized? Yes. but the equipment and costs and
energy usage and such are going to cost BILLIONS. Will all the problems be
solved. Perhaps, BUT NOT WITH ANY CURRENT LEAD FREE SOLDER RECIPES. Will the
solution ever be cost effevtive when compared to what we had with lead? No.

When you consider lead usage was NEVER AN ISSUE FOR THE ENVIRONMENT, the
arguement just becomes stupid. Rene, Spehro, Nico, try arguing that lead in
electronics was a hazard to begin with. Tell me where this was ever found to
be true, where this data is, what it was based on. You HAVE TO ANSWER THESE
FIRST, because otherwise, why the HECK would it make any sense to change in
the first place???
