Comprehensive printed circuit board cleaning agent and preparation method thereof

Abstract

The invention relates to a comprehensive printed circuit board cleaning agent which is prepared from the raw materials of, by weight: 2-3 parts of sodium silicate, 3-4 parts of Tween-85, 2-3 parts of sodium tripolyphosphate, 12-15 parts of 2-butoxyethanol, 1-2 parts of benzalkonium chloride, 4-5 parts of isopropyl myristate, 1-2 parts of sodium hydroxide, 4-5 parts of inositol hexaphosphate, 4-5 parts of an auxiliary agent, and 100-120 parts of deionized water. The surfactant of the cleaning agent has good complounding performance. The cleaning agent has the advantages of high pH buffering capacity, comprehensive penetration, good cleaning effect, and low corrosion. The cleaning agent is suitable for the cleaning of various high-precision circuit board cleaning. With the auxiliary agent, a protective film can be formed on the surface of the circuit board, such that the circuit board can be prevented from being corroded by water and other molecules in the atmosphere, and also oxidation and short-circuit can be prevented. Therefore, the next step of manufacturing process can be conveniently carried out.

Description

technical field

[0001] The invention relates to the field of cleaning agents, in particular to an all-round cleaning agent for cleaning printed circuit boards and a preparation method thereof. Background technique

[0002] With the rapid development of integrated circuits, the volume of circuit boards is getting smaller and smaller, and electronic components are getting smaller and denser. If the dirt and dust inside are not cleaned during the production process, it may cause problems such as short circuit and corrosion, which will affect the normal operation of the circuit board. At present, most circuit board cleaners are made of organic substances, which have good cleaning effect and are not easy to cause problems such as short circuit and corrosion. However, organic compounds are not only expensive, but also pollute the environment, destroy the ozone layer, and are harmful to human health. There are also a few water-based cleaning agents, but the cleaning effect is limi...
