Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel

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

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

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

Hi Paul, not to throw a wrench in here but I beleive that paople are talking about switching from SAC in wave to SN100C, NOT SACx, these are different. and should not be confused. SACx is supposed to fall somewhere in the middle of the SN100C and t

We have used the SN100C for over a year now with fanastic results. We use the SAC305 for SMT and SN100C wire exclusively. There are no problem mixing the alloys. I am also on the commitee for the NASA testing. The SN100C did out perform SAC and SnPb

HI aj, I suppose you have visited the Alphametal situ where they have plenty of information about SACX http://www.alphametals.com/main.asp For sure every one talks well about own products. I think the best judgement can be done from those who h

The most prevailent wave solder machine in small to medium UK companies is the Blundell CMS400 - every man and his dog has one. And the recommended lead free solder for these machines is..... Greg's 0.3% Silver. Quite a few of our customers use h
