Circuit board cleaning agent and preparation method thereof

Abstract

A circuit board cleaning agent comprises, by weight, 30-34 parts of butyl acetate, 12-14 parts of acetone, 12-14 parts of propylene glycol butyl ether, 4-5 parts of fatty acid methyl ester sulfonate, 1-2 parts of benzotriazole, 1-2 parts of turkey red oil, 32-34 parts of ethylene glycol, 10-12 parts of diethylene glycol monobutyl ether, 4-5 parts of additives, and 50-60 parts of ethyl alcohol. The circuit board cleaning agent is not corrosive to metal, low in toxicity, low in human skin irritation, complete in cleaning effect, capable of quickly eliminating welding fluxes, rosins, and organic pollution particles, low in environment pollution, and low in cost. The circuit board cleaning agent can form a protection film on the surface of a circuit board, air is isolated, the circuit board is prevented from being corroded by moistures and other molecules in the air, antioxidation and short circuit prevention are achieved, the next preparation process can be conveniently carried out, and the service life of the circuit board is prolonged.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a circuit board cleaning agent 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 limited and there are safety risks. F...

Problems solved by technology

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 costly, 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 limited, and there are safety risks. Further improvement of the formula and process is required to achieve the goals of thorough cleaning, no pollution, little corrosion, health, circuit safety, and cost reduction
