<< Hello Technetters:
 Being new to the list, I do not know if this issue has been discussed in the
 past, so here goes. What can be done to minimize/eliminate the residue left
by
 the no clean fluxes on the PCB's? We currently have a big issue with residue
not
 allowing our test pin probes to make contact. We have implemented cleaning
the
 probes on a regular basis, but I want to eliminate the issue altogether. If
this
 has been discussed, please point me in the right direction (archived
responses).
 If not, I would really appreciate your help.

 You could do a couple of things.  Changing to a different flux or paste
could solve the problem, depending on what you change from and to, and if you
are referring to residues from a solder paste, this is your only real
solution.  If it a wave solder foam fluxer, try running the foam head a
little lower.  If the flux is sprayed on, adjustments there to reduce the
volume used on each board might help as well.
