Any issues in your experience using SAC305 for reflow and SN100C for wave on ENIG pcbs? I've seen the CD, but there's not much specific data regarding ENIG pcbs Thanks

Bruce, Does the thicker barrel plating for "RoHS-Rated" PCBs alleviate some of the copper dissolution that one might experience from SAC305? Also, for those SN100c experts out there, is Sn100c less likely to dissolve copper?

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

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

Bob The actual process for converting from SAC305 to SN100C is pretty painless. Basic steps: 1) make sure your solder pot is at temp 2) de-dross 3) pull pumps/flow duct(s) and clean 4) purge pot of SAC material 5) remove any remaining dross/alloy i

no there is lot of difference between both the alloys.. SN100C works better than SAC305... gives little more time to remove and replace the unit without completely loosing the Cu... but there are customers who still prefer sticking to SAC305... so th

hey Jacki we are looking at going from SAC305 to SN100C, if your looking to save cost it's a cheaper option. have a look into it.

Hi Jacki, You should change to SN100C instead of SAC305. It give you excellent quality: 1. Can reduced solder short & icicles problem. 2. Very shinning solder joints. Rgds, Zaza

Yes, there have been many issues with the fast dissolution of copper by the SAC305 alloy. In fact, there are companies who have disqualified it for repair operations due to loss/thinning of the pads. SN100C dissolves copper much slower than SAC305 an

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
