| Does anyone know what the military uses for water | soluable flux in their wave solder process: | - wave flux | - rework flux | - cored solder | and approval steps to go through to qualify it. | Any information is appreciated. Thank you. Sylvia

We agree with John. It's possible to clean under 1.27 and 1 mm BGA. These devices have a reasonable stand-off that allows cleaning of water soluable flux residues with modern cleaners. So, if you have process problems with low-res fluxes, what mak

Hello, we are currently running no clean flux on our Jade model pillarhouse selective solder machine and i would like to switch the flux over to Water Soluable. Are there any concerens with running water soluable on these machines? I have heard tha

In my experience, before my current employment, I have personally seen damage from the water soluable fluxes left under a BGA. In consideration, I have not seen it from an assembly process where the boards are cleaned thoughly, but I have seen it dur

A) The standoff height of some uBGA components does not allow water to penatrate under the component. B)Water soluable may dilute the flux and not remove it all together. This can be tested with Ion Chromatography. C) Water soluable in some cases ne

The presence of agitation at an air / solution interface and a foaming agent causes foaming. Most water soluable fluxes contain surficants. Surficants are foaming agents. First, it's likely this foaming is caused by poor control of the temperature o

I have no choice, as per customer's request to remove the solder balls. Can i use water to clean away the solder ball since i'm using RMA solder paste not the water soluable paste.

I hv no choice as per customer's request to remove the solder balls. Can i just use water to clean away the solder balls since i'm using RMA solder paste and not the water soluable paste?

I will just like to know if is ok to build a board with a BGA ,with water soluable paste and washed or is better to use a no clean paste . And one last question , what do you guys think about the better paste Kester or Indium .
