| We are currently fighting a dross battle on our non-inerted waves. We are currently using a bar solder that barely meets QQS-571 for Alloy/Impurity. | | Is anybody using HI FLO in a non inerted wave? Do you see a measureable decrease in dross? |

From Alpha Metals: "The test for copper dissolution was conducted by dipping a pre-fluxed copper wire specimen into the test alloys for a specified time period. The change in diameter of the copper wire is measured and a rate of erosion is determined

Are the components 100% tin plated? Thats what we are buying and we have no problem at all soldering with the same profiles we always have used and we use the same alloy as you but different mfg. We have not had problems soldering tin plated parts wi

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

I ask for advice on starting wave soldering machine. The soldering machine is not new. Are there guidelines for properly loading solder into a bath and more. I also ask you to recommend an alloy. What do you think about Alpha Sn Plus 07 or SN100C(Sn

It doesn't appear to be a proprietary mix. Maybe it's 'neither Alpha Metals nor Kester WILL [want to] supply it.' It's interesting. A lot of the discussion of a solder replacement for 63/37 has centered on high temperature alloys. In real life,

The Technical Services Group at Alpha Metals has spent a fair amount of time looking at wave soldered Pb-free connections. We too have observed fillet tearing, fillet lifting, and pad lifting. I have concluded that without major changes in the mate
