I created a spray fluxer for our wave solder years ago that is still working well although does consume a lot of flux and is also rather messy. It's cheap and easy though so what the heck, right? I just machined a manifold that will hold four BETE

hello everyone, i'm looking for a spray gun that can withstand flux aggression. I made air controlled prototype for ersa wave machine, but air guns wear out quickly and start to leak. I was thinking about Binks model 95AR or something with stainless

I am getting ready to purchase a spray fluxing system for a no-clean process. I have narrowed it down to the Nordson or Dover system. Does anyone have any experience with either. If so can you relate with me. I am a little leary of the Nordson be

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?

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).

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

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

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
