WebThe chemistry of the flux used determines the most effective cleaning process to use. Also, fluxes having halides leave more residues. However, PCB assemblers can clean these residues using mild cleaning agents and incorporating short wash times. Halide-free no clean pastes leave fewer residues behind. However, they are more difficult to clean.
