In sufficient heat (need clean). Such as hand soldering done poorly. If it is completely reflowed properly, you have no intention to attach additional parts (not good used no clean during parts making stage, such as BGA balling), no clean better leave as NO clean.

Subject: [TN] Cleaning No Clean Flux

Hello Everyone.  I know there has been a lot of interesting dialogue the
past few days reference hand solder and flux and cleaning.  My question
is "is isopropyl alcohol acceptable to use to clean no clean flux"?  We
have Novec flux remover, but that leaves a white residue similar to what
some of you have complained about during the course of the related
thread.  Any ideas on the best way to remove or avoid this.  Also, why
would "No cleans" need cleaning?   

 

Thanks,
