In the processing of electronic information products , cleaning is an essential step in order to ensure the quality and reliability of products . Traditional cleaning process uses organic solvent cleaning agents generally have high pollution and high toxicity , such as those containing ODS ( ozone depleting substances ) and VOC ( volatile organic solvent ) , will not only endanger human health , damage the environment , but also with explosive risk . This issue through the study of the contaminants and the cleaning mechanism in the electronic processing process , and the stability of the cleaning system from the safety proceed , using water as a main solvent , add the appropriate amount of surface active agents , high-boiling solvent , cleaning aids developed good cleaning ability , corrosion resistance, electrical properties of efficient , safe , energy-saving , environmental protection, new water-based cleaning agent . On the basis of the theory of the surface tension of the surface - active agents , solvents, dissolving power for the pollutants identified on the the PCBA ( circuit board assembly ) , the printing stencil and crest stoves , screening of suitable surface- active agent and a high boiling solvent . Orthogonal method conducted a series of complex test to obtain a highly efficient emulsification of rosins, resins , organic acids , a thixotropic agent , corrosive ions flux residues and welding process stained contaminants , dissolving capacity strong multicomponent mixed surface active agent and a high boiling solvent . The study showed that the synergies multicomponent surface -active agent and multi-component generated in the high boiling solvent compound after its washing power is significantly better than the single-component surface-active agents, solvents . The article also Characterization and PCB ( printed circuit board) , flux , solder paste , solder wire material compatibility test , optimize the formulation and verify its research and development of cleaner cleaning power , electrical , corrosion , and other aspects of nature reliability, conduct a small test , pilot studies , and to get the best cleaning process . Good recipe combines the best of the cleaning process research and development of electronic technology water-based cleaning agent has a good application value .
