We have qualified an Alpha VOCFree no clean.  The NR310 series is a good
flux as far as solder balling goes.  It is compatable with alot of
finishes.  They not only concentrate on the surface tension of the solder,
but with the coating as well.

Subject:  [TN] : Anybody using water soluble ?




The text of this message is a "re-run" of an earlier message for which I
only received one response. Just looking for a few more.

Greetings:

I am curious whether or not someone has ever qualified a water soluble flux
for wavesoldering in accordance with J-Std-001B, Appendix D. I have
previously qualified Kester  HF-1189A flux in accordance with J-Std-001A,
appendix D. At that time I was able to select a flux that was QPL listed
under Mil-F-14256, type WSF, and qualified our process according to the
appendix at level 2. Since then, J-Std-001 is now Rev B, Mil-F-14256 is a
thing of the past, etc etc.

So......

Are there any Class 3 producers out there who have gone through the
qualification of water soluble fluxes according to the provisions of
Appendix D ?? I'm just curious as to whether or not someone was able to
qualify something other than Kester HF1189A  to the J-Std.

I'm interested in changing water soluble fluxes from the water based to an
alcohol based water soluble flux. I'd like to know if anyone out there has
been sucessful in passing the Appendix D requirements for class 3 activity.

If you're still using RMA's, how are you cleaning ?


Thanks,
