Apply the bare minumum amount of VOC free typically 50% less than alcohol fluxes. By doing this you can keep the same top board temperature as alcohol, its only when people over flux do you need to boost up the preheater to volatise of the water. NEV

Could you not just switch to alcohol based flux? If your prob is getting the water off the board prior to hitting the wave, maybe you could install some type of convection to aid in this? Russ

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).

I am considering moving my spray fluxer into a completely separate operation. Has anybody any comments of sraying VOC free flux on boards, then putting them in a drier/holding rack for possibly say overnight, then running them through wave solder?

As we are a low volume shop, the extra handling is not too much of a concern. My biggest concern is if the flux sitting on teh board for a long time (few hours) is going to cause any problems in solderability. My thought is that it should not as it

Yer not making this easy. What kind of flux? If no-clean flux, what controls are you using to assure you are: * Applying the correct amount of flux? * Properly activating the flux? If water washable flux, talk to us about your cleaning methods and

J-STD-001C, 7.2.1 Flux Application says words to the effect of: When an external flux is used in conjunction with flux cored solders, the fluxes shall be compatible. Regardless of whether these are or not flux cored solders, this begs the question:

We made the same change a year ago, from foam to spray fluxer. One of the reasons we changed, to keep the acid number within specs (foam fluxing) we had to measure once or twice a day and add DI water to make up for evaporation, all along not able to

Hi Everybody, In our process we use syring flux for repair the boards, both SMT and PTH. I would like to know with your experiences what kind of flux is better for SMT and PTH repair, PEN or Syring flux??

SonFlux EZ is not suitable for water SOLUBLE flux. SonoFlux Servo can be equipped with parts that whitstand corrosive water soluble fluxes. SonoFlux Servo was about 19k€ in 2011 (including installation).
