Hey guys, Anybody having trouble with increased false contact issues in ICT after switching from lead to lead free? Our test guys keep trying to imply that the flux residues are a problem (we're using Alpha EF2202), but as the soldering process eng

I think the BLT solder joints look very shiny for no-lead. We are getting very good top side solder with ours though. They look like this. - Gold Enig plating - Alpha EF-6100 Flux - SAC305 - Preheat topside temperatures at 110 to 120C

I am using AIM Electropure SN63/Pb37 Solder, & AIM NC266-3 Flux; just like what ACE recommends. I have both Ultra High Pure T-Tanks and a Cryogenic Dewar Tank for Nitrogen, and neither seems to have improved the problem. I place a piece of tempered

I have had Selective issues such as yours on two very different Selective Solder Machines. I was able to eliminate these issues by using Alpha EF-9301 wave flux with any SAC305 solder. It's a more aggressive flux, but really made the difference. Anot
