Why are you planning to clean low residue flux? There are cleanable low residue fluxes, but why would you wan to clean it?

You need to remove the oxide before you can properly solder your [or any] component. Call your flux supplier ask them for a more active flux than you are using and for their recommendations on removing the flux residues.

We always talk about the halide free fluxes and solder pastes. Is there anyone tell me what is the industrial acceptable level of halide content or contamination in flux residue? All comment are welcome !!! Kelvin

Kevin: What was the thinking behind your using a flux that required cleaning �on a post wash assemble for a power switch�? How do you keep the remaining corrosive flux residues from causing trouble [ie, corrosion, CAF, etc]?

Paste is eutectic and it's copper based parts. Just another observation, i notice that the "flux" between the bottom foot and solidified paste is still in gluey state. Observation on good reflowed leads showed brittle type of flux residue. Can anyone

Washing these boards would be a great help. The flux will build up on the probes and possibly corrode them depending on it's composition. Aim for a process that will burn off the majority of the flux, or change chemistries if washing is not an opti

Folks, we've recently upgraded to Heller MKIII reflow ovens with Gen 9 cooling units. We're running N2 atmosphere at 1000ppm O2 and Kester256 solder paste. We're seeing a big problem with flux residues building up in the cooling section of the

I am using kester 958 no clean in an Electrovert Econopak 2 and having trouble with white residue, the solder pot has a foam fluxer and I have tried diferent setings on the air knife angle & pressure, the top board temp is aprox 200F.Any help would b

I do know Zestron makes a flux residue remover .....but to what degree I can say. Contact Andreas at Zestron for more info. Cal

depends if your water wash process is manual or automation? important is the water residue inside the via holes is adequately blown out. As long as the water-flux residue is out, testing down the line should not be a issue, at least from theory and o
