Method.
Background technique
As electronic product is quickly to the development of miniaturization, high-precision and high reliability direction, in electronic manufacture
More and more pollutants are introduced in technique, such as assemble wiring board during dress connection welding, in order to ensure welding
Reliability, it is necessary to which, using the higher scaling powder of activity, these welding assisted agent residuals can etching lines plate and member on assembling wiring board
Device, while its surface insulation resistance can be reduced, especially under the condition of high temperature and high humidity, it may appear that serious corrosion and electric leakage,
Influence the reliability of complete machine.The residue assembled on wiring board is mainly the electronic weldings auxiliary material such as solder(ing) paste and scaling powder
Residue, hand perspiration, finger mark and the pollutants such as the fiber fallen in the air and dust left in operating process, these material compositions are multiple
Miscellaneous, containing the ingredient not soluble in water such as resin, grease, activating agent, there are also anions and canons and weak organic acid.Therefore in order to ensure
Electronic fabrication processes are gone on smoothly, and guarantee product quality and reliability produced, it is necessary in many links of process implementing
It imports cleaning process and uses cleaning agent.
Traditional cleaning process generally uses the ODS cleaning agent containing freon, such cleaning agent have chemical stability it is good,
Small toxicity is not burnt, many superiority such as surface tension is small and is able to maintain stronger permeability and rapid-drying properties, but ODS class
Cleaning agent has extremely strong destructive power to ozone layer, and greenhouse effects are serious, seriously endangers the ecological environment of the mankind, in addition, such as hydrogen
Chlorofluorocarbons, perfluoroparaffin and other halogenated hydrocarbon cleaning agents, it is all harmful to environment and human body.Therefore, the electronics of environmental protection is developed
Industrial flux cleaning agent is with regard to very necessary.
Chinese patent (CN102851151A) discloses a kind of used in electronic industry environment-friendly cleaning agent, including 2- methylpent
Alkane, dehydrated alcohol, ether solvent replace n-hexane using methylpentane, reduce cleaning agent to the toxicity of human body, and weld to helping
Rosin in agent has good solubility property, and ether solvent has good solubility property, anhydrous second to the organic acid in scaling powder
Alcohol plays the role of degreasing well, but the cleaning agent prepared is still toxic to human body, and moisture-free, is easy to clear
It washes device to pollute and remain, causes secondary pollution.Chinese patent (CN106635460A) discloses a kind of water-base electron work
Industry flux cleaning agent and preparation method thereof and application method, including high-boiling point alcohol ether solvent, n-methyl-2-pyrrolidone,
Ethyl alcohol, nonionic surfactant and water.Wherein higher boiling alcohol ether can prevent the volatilization of cleaning agent, reduce in cleaning process
Loss, joined water, improves its safety, while resin, scaling powder, touching of the cleaning agent to all kinds of electronic circuit plate surfaces
The purpose of Rapid Cleaning can be played by becoming agent, thickener and other pollutants, and cleaning efficiency is higher.But according to above-mentioned
The prior art develops aqueous electronics work it is found that cleaning agent water base in electronics integrated circuit board flux cleaning agent at present is less
Industry flux cleaning agent has market prospects.
