Hello Brain,
Sorry could not complete the mail.
Now we are facing the cleaning problem in the boards which are processed in
wave soldering. After wave soldering process, we are cleaning the flux
residues and this process is taking more time to effectively clean the
boards with IPA (more time consumed to clean the white patches formed due to
IPA, which is not good in cosmetic). The PCBA is a communication purpose
boards (Class B according to IPC). Now we need to try out any other solution
which is effective in cleaning and should not be harmful for the board. If
any other information is required, please let me know.
Thanks in advance
Raghav

IPA is not a good solvent for most types of flux residue, because it
will not dissolve many components. Tell us more about what you are doing
(soldering methods and parameters, flux type, type of end product,
degree of reliability needed, conditions of use of end product and so
on) and we shall be able to help you better.
