I am sure this has been beat to death.


If you have BGA's with lead free balls can you solder these
in a leaded process.

I have 7 different BGA's on this board

So if they are all leaded and I go with a leaded process life is good.
If they are all lead free and I go with a lead free process life is good.

But what if I can't get them all in one flavor.

I know that one way is really bad. Isn't it soldering lead free parts in
a leaded process? I could imagine that you won't get hot enough
to reflow the lead free balls. But what about using non lead free
BGA's in a lead free world.


Any input on this will really be appreciated.

Thank You
John Foster
