If the balls are SAC then you may actually reflow them at 217C. Of course, I may be assuming they are SAC...

Yes you can, we have done it for years. Russ

Hi, Great, and thanks for the info, it's a big help to know someone's actually done it, and so we will give it a try on a few dozen product, and see what happens! Thanks again for the reply! Regards, Grant

John, is this regarding any certain alloy of the ball? Thanks

Hi, I agree, and this is why I wondered what peoples experiences were, and it is a bit confusing. Regards, Grant

Damn, we are doing that too! What is the issue there? Russ

I don't recall if a specific alloy was mentioned just that most lead free alloys would not melt with a Pb profile and result in a less reliable joint in the long term. There was also concern about tin whiskers. Try the archives at http://www.ipc.or

HI, I actually have ask the same question a while back. Yes, using lead free component in a leaded process should be no problem at all. May required just a little hotter peak temp. during reflow, to achive optimal solderability.

I need information on where I can purchase Lead free solder paste and solder wire samples. I currently use SN63/PB37 no clean solder paste in a 35G tube and SN63/PB37 no clean solder wire for rework. I would like to try out some samples of Lead fr

Could you advise what is the min and max peak temperature for this process. Presently, my leaded peak temperature at the range of 215 - 225 deg.C And how do I know that the solderability is at optimal. Appreciate your help......
