Hi Ken:
We would suggest to clean the board prior to conformal coating.
For a current client we have to clean the no-clean (SAC305) prior to parylene coating. This promotes adhesion and prevents voids from forming.
Regards

Subject: [TN] Conformal Coat Over No-Clean Flux
To: [log in to unmask]

We have a twelve leaded, through-hole component that has to be hand soldered
on the circuit board. The assembly gets conformal coated with urethane. We
would like to hand solder these twelve leads using no-clean and then
conformal coat the board. The component would be added as a final step after
the assembly has first been cleaned.
Since this is not a "total no-clean" process do you see any issues applying
conformal coat over these twelve no-clean solder joints?
Best regards,
KennyB
