I've tested boards with SN100C HAL finish, and wetting to the PCB finish was poor at best, using a no clean SAC305 paste.

Jacki, your original post was regards to wave solder bath. With solder bar, there is no flux and you do not need to look for WS Sn100C. Sn100C is only a metal alloy. Regards, Shean

Hello Arnold, Yes, by definition of joint formation, copper will dissolve in lead free solder in order to form the connecting intermetallic layer. There is a distinct difference in the copper dissolution rates of the major alloys being considered wi

This make me curious how many people are using sn100 versus how many using sac305. The sn100 seemed to generally cover the pads and flow a little better, and looked nicer, but SAC305 overall was easier. Is this normal or do I need to work more on sa

Not sure about Sn/Cu/Ni large market share here in Europe as we have a large part of the UK market with SACP0307 alloy 0.3%Ag introduced over Two years ago Also worked against Sn/Cu/Ni alloy with large TV Co and they went with 0.3%Ag due to reliabili

If you add any "flux cored" wire solder to the pot make sure you have ventilation as the flux will burn off and smoke like crazy. This solder pot is like any used in a wave or selective solder, no flux. The flux is added to wire prior to di

We started with SN100C from the very beginning when we purchased our selective solder machine. It has been working well for us. I can't speak to what happens when changing over to it, but I've heard of many companies using SN100C for selective sold

Glenn, What alloy are you using for Pb-free HASL? You say tin copper nickel, but is it SN100C? Against manufacturing engineering's recommendation, my company specified simply "Pb-free HASL" as the finish for our Pb-free PCBs. One of our suppliers

Hello Arnold, Just to clarify the Sn100C discussion: Please note that SN100C is the Nihon Superior alloy composed of tin/.7copper/nickel. The key point in regard to SN100C is that Cu does not go directly into solution but first reacts to form an inte

Sheldon, Try using SN100C wire solder. It seems to extend the life of the tips plus solder joints look much better. We use both, clean and No-clean. We had the same problem while using SAC305... Thanks, George
