Should I have any concerns with operators using flux for handsoldering, straight out of a 25 ltr drum which is not even thinned dowm to the correct SG level. The flux is Alpha 615-25 RMA based and we use it in our wavesoldering process. Thanks in ad

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

I have chceked the fluxing application, I seem to be getting good consistent coverage across the board using our foam fluxing system. Good flux penetration on the top-side of the through-hole plating, as this was checked using a fax paper.There is no

Scott is right, Alpha' 2110 is a good saponifier (be careful though as it can dull your leads). Saponifiers in general are better if used in an aggressive spray-in-air system. Low agitation immersion systems (heated baths or refurbished vapor degre

We currently use an ESP RMA paste. The reason that I initially posted the question was because we are conducting tests to see if this is infact the best paste for our processes. In running tests, however, certain variables, such as humidity, are ou

The variance of useability of any of the pastes with a difference of 5% in your overall environment will probably not even be measurable in the difference of the paste be it RMA, Water Soluble, or No Clean. What is the printer you are using and is i

We are producing boards with Alpha 591S RMA No-Clean paste and are coating after SMC with Dow silicone ( toluene solvent based) conformal coating. We have experienced several failures due to soft shorts ( electrochemical migration?) We have also obse

Cory, I've got a lot of experience of testing of this type. The physical (not chemical) nature of the flux residues is the crucial issue in compatibility. If you have a softer residue (either caused by a thick initial solder paste deposit, or a low p
