I have a question concerning repair of a CCAs soldered with
no-clean flux (hand soldered and/or wave soldered).
If you need to repair/rework the CCA, do you use an RMA flux
for the repair/rework or no-clean flux? If you use a
no-clean flux, how do you know if you have flashed off all
the flux that was applied? Wave soldering pretty much
covers the entire bottom side flashing off the no-clean
flux, however, a soldering iron may not do that.
If you use an RMA and clean then it would seem you are
defeating the purpose of the no-clean. Will that cause a
problem since the rest of the CCA was soldered using
no-clean?
I have heard of cleanable no-cleans, but, what if you are
not using a cleanable no-clean. Could someone straighten me
out on this issue? Thanks!
