Problems solved by technology

However, for different cleaning requirements, cleaning methods and cleaning environments, it is difficult for a single component to achieve the ideal cleaning effect, so it needs to be mixed with other solvents with different characteristics to form a composition to meet various cleaning requirements

Abstract

The invention discloses an electronic component cleaning agent. The electronic component cleaning agent comprises the following components: polyepoxysuccinic acid, alkyl polyglycoside (APG), an acid cleaning agent, secondary alkyl sodium sulfonate (SAS), hydrofluoroether, a water soluble organic amine pH value regulator, a defoaming agent, methyl epichlorohydrin, a stabilizer and an organic solvent. The invention provides a cleaning agent used for an electronic component. The cleaning agent takes hydrofluoroether with ODP of 0 as a main solvent to be matched with other components, environmental protection, low toxicity and low greenhouse effect requirements are met, the cleaning agent has good cleaning property, produces fewer foams, is non-corrosive, low in volatility, less in residue and low in viscosity and can well clean the electronic component without producing harmful effect to the electronic element.

Description

technical field [0001] The invention relates to a cleaning agent, in particular, the invention relates to a cleaning agent for electronic components. Background technique [0002] In the production process of electronic components manufactured by the electronics industry, the surface of the electronic components needs to be removed before assembly, such as glue traces and flux residues. Cleaning the components with a cleaning agent is an essential process. Some of these substances may need to be manually operated or implemented in a confined space. These requirements not only require that the fluorine-containing cleaning agent has a good decontamination effect on glue marks and flux residues, but also requires that the fluorine-containing cleaning agent is safe and environmentally friendly, and has a fast volatilization rate. Low toxicity, low odor, non-flammable. Most of the cleaning agents used are fluorine-containing compounds as solvents for fluorine-containing cleaning...
