Hi everyone We plan to use on our smt line sac 305 and on our wave soldering sn100c. Will there be a compatibility problem if we do make touch up with sn100c on smt or touch up thru hole components with sac 305 ??? Thanks for taking time to reply

Hi, That would be interesting. We are running SN100C and it's as good lead wave solder from our experience, and some people have competed on it here on the forum, but no one has reported they are using SACX yet, so it would be good to know anyones e

Just wondering if there are any users of SN100C lead free hasl finsh out there. If so what kind of results are you getting as far as solderability is concerned?

We have been using SAC 305 for reflow and Cobalt 995 (very similar to SN100C, only cheaper) for wave and rework for quite a while now with no issues that I'm aware of.

Hi, I have heard that some have added small amounts phosphorus to SAC alloy in wave soldering and this way decreased drossing. Does anyone experienced this with SN100C? Regards, Juha

Be sure to peel the potatoes. I saw a guy use a potato to purify gold on the TV show Rough Science. Seriously though I would think SAC305 to SN100C wouldn't be as bad as eutectic to leadfree.

I wanted to hear from users of the SN100C alloy to find out what they think is positive and negative about this lead free alloy. Thanks, Keith

Loco: Your post seems to be pasted from a Alpha Metals SACX0807 application sheet. We don't understand the relationship between your SACX0807 and Hoss67 SN100C. They're different alloys.

Indeed Dave, But I can't image the extra .5% silver that alpha adds to sn100c will make a huge impact on the difference between the behaviour of the 2 alloys, especially considering SAC gets exactly the same recommendation.

As a distributor we sell very little SN100C for SMT, we sell far more SAC305 for SMT. The higher temperatures are the reasons.
