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

According to Howard, we clean the flux tank on our wave solder machines every week. We replace it because flux sops up moisture from the air and contaminating materials from boards that are being fluxed prior to soldering. How would a prudent perso

Is there anyone who knows what the influence is of the dip-fluxing process on the placement accuracy of a flip-chip. If you perform dip-fluxing after component alignment, the component may be displaced on the nozzle; if you perform component alignmen

Consider: * 007 is a no-clean flux. Some no-cleans you can clean, some you can�t. You may be able to use a saponifier & surficant to clean the residue. Check with your flux supplier for recommendations. * 320�C is higher than the 315�C peak for th
