We are using SAC for reflow because of the lower temp and better wetting and copper disolution is not so much an issue in reflow. There is not much difference in the alloys and they can be mixed with no problems. I assume any supplier of SN100C cou

We have tested SN100C for LF wave soldering process since August'05 and currently start production for a month ago. Initially we use SAC305, but due to the shrinkage cavities (micro-crack) we changeover to SN100C. In summary, SN100C did perform well

We bought the lead free pots for the Ersa machine and change back and forth. We had a lot of problems running SAC305 in the Ersa. It seems to create a ton of dross and you need to frequently clean and flux the nozzles. I would really like some feed

has anyone used or trialed the SACX from Alpha, > from reportes and studies carried out it seems > that its a go between SAC305 and SN100. Same question re: Kester's K100. Apparently it's a new .6% Cu alloy that they haven't yet begun to market h

We are using selective soldering pallet, which the soldering flux is Interflux 2005M. We encountered the poor hole fill mainly at the heat sink components. Initially we tried to apply more heat but tend to overkill the flux activity. After some modif

Hi Guys I think you should all be looking at the Nousstar lead free machine this machine has been approved with some of the larger oems and has a good base in Europe and the uk we have one and the design is excellent we are using Aim for class 3 prod

Hi Grant, I've seen a couple of good fluxes on lead free - WF-7742 from Indium & JS-EU-01 from Koki. I'm sure everyone else has a good one too - just make sure it is one formulated for the elevated temperatures involved. Cheers, Rob

There is one solder you guy want to consider, that is SCS7 from Asahi. It is Sn Cu & Si, and it is the lowest price at the moment. We had been changing our pot from SAC, then SACX, and recently to SCS7. The result is better than all other solders. I

We are thinking of switching over from sac305 to sn100. Has anyone had any experience with this changeover and is there any drawbacks to switching to sn100?

I'd say it depends on the whole process you have. With our 5 zone oven, I could never get a profile that worked as well as SAC305, so we switched back.
