Hi John,



It's well doable. You may want to look up the forum archive to find out how to do it.



Regards,



Vladimir

Subject: [TN] BGA's and lead free



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
