Thats because Glenbrook Reps both. The Ersascope was the original and still is the best bang for the buck. How do you know if you have flux residue under the bga without seeing it. Show me an xray system that can see flux residue? Again, this is a PR

This may be worth checking out are you sure it is flux residue and not undercured plasicizers coming from solder resists due to the higher Lead Free temperatures killing the undercured resist, this causes many no faults found and bridging, solderball

Have you examined what type of residue is present? It is possible that what you are seeing is benign, though flux that is not fully activated often leaves harmful residue species such as chloride or weak organic acids. If you don't want to change p

YAAAAAAAAAA! You guys from Chemtronics are saying that hand cleaning water soluble flux residues are okay? YAAAAAAAA! that's complete MADNESS! Please clarify! -Steve Gregory-

my 2 cents here --- Even though the boards need not be cleaned after SMT when using no clean flux, you will still have to clean them before conformal coating.....and most solvents used to clean boards before coating will take out the no clean flux re

Does your fluxer provide for very fine atomization of the flux or is it more "droplet like" Great term huh?

Smartasp - What are your lead to hole ratios like? Dial down the flux and open up the holes, if you can. Keeping at least a 14-20 mil gap between min hole/max lead solves the hole fill problem. L

At the end of the day, you won't notice a difference, while soldering, but if you clean the flux residues.

Its most likely flux residue from your paste. This is normal in my experience. Just clean it out. Some paste fluxes are waaaay worse than others.

Jim, We are experiencing voids, also at Selective, on a transformer with known flux residue issues. The supplier told us they were using a OA, or RMA flux which has to be cleaned, and we accepted these parts anyway. How does the "separation speed
