Problems solved by technology

[0004] Chinese patent (CN102851151A) discloses an environmentally friendly cleaning agent for the electronics industry, including 2-methylpentane, absolute ethanol, and ether solvents, using methylpentane instead of n-hexane to reduce the toxicity of the cleaning agent to the human body. And the rosin in the soldering flux has a good solubility, the ether solvent has a good solubility to the organic acid in the soldering flux, and absolute alcohol has a good effect of removing oil stains, but the prepared cleaning agent is still harmful to The human body is toxic and does not contain water, which is easy to cause pollution and residue to cleaning devices, causing secondary pollution
But, know according to above-mentioned prior art, the cleaning agent of water base is less in the electronic integrated circuit board welding flux cleaning agent at present, and the development water-based electronic industry welding flux cleaning agent has market prospect

Abstract

The invention relates to the technical field of cleaning agents, in particular to a water-based electronic industrial scaling powder cleaning agent and a preparation method thereof, the water-based electronic industrial scaling powder cleaning agent comprises the following components in parts by weight: 50-70 parts of high-boiling-point alcohol ether, 20-30 parts of terpineol, 1-2 parts of a corrosion inhibitor, 1.5-4 parts of an emulsifier, 1-2 parts of a penetrating agent, 1-2 parts of an alkali and 10-20 parts of deionized water. The novel PCB water-based electronic industrial scaling powder cleaning agent disclosed by the invention is an environment-friendly cleaning agent, and a fluorine-containing carbon solvent and a halogenated hydrocarbon. No threat is caused to human health. Thewater-based electronic industrial scaling powder cleaning agent is convenient to use, environment-friendly, safe and simple in using method, by diluting a concentrated solution according to requirements, and carrying out ultrasonic wave or spray cleaning, the scaling powder cleaning agent on the surface of a PCB can be effectively removed, and after the PCB board cleaned by the cleaning agent is subjected to water rinsing and air drying, the next procedure can be directly carried out.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a water-based electronic industry flux cleaning agent and a preparation method thereof. Background technique [0002] With the rapid development of electronic products in the direction of miniaturization, high precision and high reliability, more and more pollutants are introduced in the electronic manufacturing process. For example, in the process of assembly and welding of assembled circuit boards, in order to ensure Soldering reliability requires the use of highly active fluxes, which will corrode circuit boards and components and reduce their surface insulation resistance, especially under high temperature and high humidity conditions. Severe corrosion and leakage affect the reliability of the whole machine. The residues on the assembled circuit board are mainly residues of electronic soldering auxiliary materials such as solder paste and flux, hand sweat, fingerprin...
