Ivan,

We need to use low solids fluxes of the type 1.8 or 2% solid content. There
are some self cleaning probes also available (I saw some ad long time
back). If you are using the spray fluxer than you may reduce the amount of
flux applied to the board.

Subject:  [TN] No clean flux residue




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.
