Embodiment Construction
[0006] The invention provides a non-metal component cleaning agent, which is applied to the decontamination of non-metal materials or parts of electronic components, and is characterized in that: its composition according to weight percentage is as follows: surfactant 6-8%, 1-3% of auxiliary solvent, 0.3-0.5% of anti-corrosion and anti-rust agent, and the rest is deionized water; the surfactant is an ion-nonionic surfactant; the auxiliary solvent is a polyhydric alcohol solvent.
[0007] As a further improvement of the present invention, the anti-corrosion and anti-rust agents are triethanolamine oleate and benzotriazole. The polyol solvent is any one or a mixture of ethanol, ethylene glycol, propylene glycol, glycerol, and isopropanol.
[0008] As a further improvement of the present invention, the ion-nonionic surfactants include: anionic surfactants, mixtures of anionic surfactants and nonionic surfactants, or mixtures of cationic surfactants and nonionic surfactants mixtu...

The invention discloses a nonmetallic element cleaner which is applied to the cleaning of nonmetallic materials or components of electronic element parts. The nonmetallic element cleaner is characterized in that: the cleaner comprises the following compositions in percentage by weight: 6-8% of a surfactant, 1-3% of an auxiliary solvent, 0.3-0.5% of a preservative and a rust inhibitor, and the balance of deionized water, wherein the surfactant is a ionic-nonionic surfactant; and the auxiliary solvent is a polyol solvent. The cleaner disclosed by the invention can carry out effective cleaning on metal ions, organic and inorganic impurities and solid particles on the surfaces of electronic materials, and the cleaning force is strong; after the cleaning is completed, liquid can be directly drained without causing pollution to the environment; and materials subjected to cleaning are not corroded and rusted. The nonmetallic element cleaner disclosed by the invention is particularly beneficial to the cleaning of nonmetal parts such as semiconductor wafers, electronic glass substrates or LCD (liquid crystal displays), and the like.
Description
technical field [0001] The invention relates to a cleaning solution for electronic components, in particular to decontamination of non-metal components in electronic components. Background technique [0002] In the production, processing and preparation process of electronic products, taking the preparation of semiconductor components as an example, physical and chemical treatment processes such as metal coating process and mechanochemical abrasion process are usually required, so physical and chemical residues will be formed on the surface, such as metal Impurities, organic and inorganic impurities and solid particles. These residual substances not only affect the appearance of the product, but also may cause toxic hazards to the subsequent processing, affecting the accuracy and life of the product. With the improvement of precision requirements for semiconductor components, the removal of impurities and contamination will be an inevitable requirement. Of course, these re...
