The water soluble flux residue is staying there because the rinsing temperature it may be too low. The flux needs about 130-140 degrees celcius to become soft. If you are using water soluble flux, as per IPC A 610 standards it needs to be remove comp

Here are the scenarios: *No-Clean Flux & Foam Fluxer: alcohol is used as a thinner (for titration purposes) if your flux is alcohol-based *No-Clean Flux & Spray Fluxer: alchol is used only as a cleaning agent for your sprayhead.

I should have mentioned... the only flux we use for the hand soldering is wire-core, no bottle flux. I think it should be a non-issue to leave the activated wire core flux residue. I'm just looking for some way to prove it to the designer.

What flux are you using? We use a low-solids No-Clean water-based flux. Maybe some of what you are seeing is not residue from the flux but is from reaction with the solder mask.

Hi All I received some advice 1) use Flux with Thinner 2) use Flux with Water. Which one is better for my wave sodlering? The type of Flux is watersoluble.

Dear Dave Thanks for your advice.I dun know why flux can't use alone w/o adding other solvents. is it neccessary? Now, our flux density is 0.88. By the way, we use Hi Grade Flux 1080.

David, Your concern is legitimate regarding the aggressiveness of VOC free flux. Water (the main substance of VOC free flux)is much more aggressive than alcohol. You will have an increased need to be more cautious from a compatibility standpoint, r

It depends on the flux and the down-stream processing ... * If there is adequate down-stream cleaning: We are ambivalent. * If the flux is low residue and there in no down-stream cleaning: We don't like using a syringe because it squirts liquid flux

Same happenend to me with another flux some years ago, to me its a reduced viscosity of the flux, what I did was to reduce the width of the slot on top, where the flux exits, reduced the distance from stone to pcb and filled the flux reservoir to the

For some, not all, hand assembly, we use additional flux. We use a flux pen in certain applications and liquid flux in other applications - you can't just say switch to a flux pen, it isn't always adequate. Most flux pens are ORL0 with very low sol
