Some manufacturers will not even identify the change with a new PN. So it will affect everyone in some way or another, since you will be able to buy only Pb-free components. My understanding is that Pb-free components are chemically compatible with SnPb solders, BUT you still need higher reflow temperatures or the the yield & reliability suffers.

The change is happening right now. some components are already shipping
with a Pb-free finish. Some manufacturers will not even identify the
change with a new PN. So it will affect everyone in some way or another,
since you will be able to buy only Pb-free components. My understanding
is that Pb-free components are chemically compatible with SnPb solders,
BUT you still need higher reflow temperatures or the the yield &
reliability suffers. Anyone have any comments?
