Cleaning printed circuit board of the traditional method is to use organic solvent cleaning, composed of CFC - 113 and a small amount of ethanol or isopropanol) of mixed organic solvent of rosin flux residues has good cleaning ability, but because of CFC - 113 to the atmospheric ozone layer damaging effects, 2013 has been banned from use, can choose non ODS cleaning technology including water-based cleaning, semi aqueous cleaning, solvent cleaning, can also be used for cleaning free cleaning process.
1, chlorinated solvent wash plate water; chlorinated solvents and other mixed solvent; the dissolution of rosin and removing flux speed. After cleaning without residual volatile no need drying characteristics. Such as Yu full industrial environmental wash water FRB-1.1.
2, hydrocarbon solvent wash plate water; with hydrocarbon cleaning agent is widely used, hydrocarbon solvent has also been used for cleaning of printed circuit board (PCB); hydrocarbon solvent wash plate water type of quick and slow dry type; quick drying type cleaning effect is generally good, hydrocarbon solvent wash plate water with environmental protection, non-toxic, low odor, can be using distillation recovery. It is mostly used for high precise PCB circuit board cleaning, such as hydrocarbon solvent wash plate water FRB-143.

3, water-based wash plate water; because water-based cleaning agent with environmental protection, safety, non-toxic, non irritant gas volatilization characteristics, the author found that the 2013 market a water-based wash plate water, but due to the circuit board are pin of a metal element, if water-based plate washer water does not have the rust proof function should be used with caution, because water-based cleaning agent to accelerate the pin of the corrosion rust.
