for SMDs, try to look for EIA-481.1.2.3, or may be the new version EIA-200 if I am not wrong. Also IEC 60286-2 (leaded components like axials, radials,..) Regards......GS

Many high rel assemblers reball their LF BGA with SnPb balls. In other less demanding environments, SnPb paste with LF BGA produces acceptable reliability.

Several paste manufacturers make an interim paste designed for such mixed applications. They work pretty good and give you the strongest joint available.

Hi All, Has anyone out there used an Airvac DRS-22 for RoHS rework on lead free BGA's?

Got a picture? Most times I hear this situation it turns out to be a bent leg on a thru-hole transistor that didn't go through the board.

Ask Brain Toleno at "circuitsassembly.com/blog" He's a smart guy and works as team lead at Henkel Loctite. Just don't take him out for drinks.

Thanks for the replies guys. I hope I didn't throw ya'll off with the "lead free" remark but I just wanted to be as clear as possible, as to what we are running. So far it sounds like it's worth looking into. Thanks again, pr
