Cleaning RMA with water is bad news. It will turn your solder connections white and remove none of the RMA residues. There was a thread on removing RMA within the past two weeks on SMTnet. Check the fine SMTnet Archives. Additionally, look at M

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? Thanks

Hi All, Just have a share with you guy. We are using T4 solder paste and also E-Stencil. We ahd try out Alpha, Kester, AIM and Qualitek. The result show Alpha had a very very heavy stack flux and can't get it clean off even by chemical

in a thread titled ".5mm bga" there is a reference to a paste by alpha that is no-clean and is supposed to be made specifically for this situation. I suppose that increasing the pad dimension to .012" is out of the question? Russ
