Abstract

The invention belongs to the field of a circuit board cleaning agent, and discloses a water-based environment-friendly cleaning agent for circuit boards. The cleaning agent is prepared from the following raw materials in parts by weight: 1-2 parts of potassium polyoxyethylene lauryl ether phosphate, 1-2 parts of sodium sulfate, 1-2 parts of tetrafluoropropanol, 1-2 parts of sodium citrate, 2-3 parts of benzotriazole, 3-5 parts of isobutanol, 3-5 parts of triethanolamine, 3-5 parts of polyoxyethylene ether, 4-6 parts of diethylene glycol monobutyl ether, 10-15 parts of coco fatty acid diethanol amide and 30-40 parts of de-ionized water. The cleaning agent disclosed by the invention has no problem of stratification, and is good in stability and free from corrosion to metal; and in addition, the cleaning agent is good in compound removal effect.

Description

[0001] technical field [0002] The invention belongs to the field of cleaning agents for circuit boards, and relates to a water-based environment-friendly cleaning agent for circuit boards. [0003] Background technique [0004] If the dirt and dust inside the circuit board is not cleaned cleanly during the production process, it may cause problems such as short circuit and corrosion, which will affect the normal operation of the circuit board. The cleaning of circuit boards during the manufacturing process includes, in addition to chemical cleaning using detergents, cleaning methods such as electric pulse cleaning, optical cleaning, high-pressure water jet cleaning and ultrasonic cleaning. In practical application, the existing various cleaning methods always have various insurmountable technical defects or regulatory restrictions, and it is difficult to meet the requirements of modern industrial development. [0005] Among the various cleaning methods, chemical cleaning...
