Is it possible for flux to evaporate out of the solder paste, and how long would it take? What kind of effect would this have on reflow if all the flux evaporated?

No, but it does evaporate slowly when left open. It is used in electronics cleaning because of it's solvent and evaporative qualities. You can look up references like the CRC handbook to compare these properties side by side to other alcohols that ca

Larry Elaborating on the specific question, yes, the volatile solvents in the flux can and will evaporate. Evaporate completely in any reasonable amount of time? Probably not. What tends to happen is that the exposed paste dries on the surface and

Consider these three potential causes: 1) too much sludge - if the sludge builds up around or over the temperature sensor, then the sensor does not get an accurate reading. 2) too much chemistry in the evaporation solution - Check the temperature a

Good question - as it is a water based flux then you are going to get a very low level of solvent evaporation, and it's hardly going to be absorbing additional water whilst sitting around. (you actually want the water (carrier element) to evaporate).

Brian, my main conceren was it evporating once it was printed on to the board before placement.

Dear C.K. I agree. The older style "generic" evaporators are cumbersome. However, you should checkout the new Model EZ-0 Wastewater Evaporator. It is made by Smart Sonic specifically for the SMT industry and addresses all of the maintenance relate

MK, In most cases, if the machine is completely closed-looped (prewash, wash, prerinse, rinse, final rinse etc), then the water should not require changing. As with most inline cleaners, there should be a considerable amount of water loss in the cl

This was my first thought too. Something to do with he flux application or evaporation etc..
