Printed circuit board cleaning agent and preparation method thereof

Abstract

The invention relates to a printed circuit board cleaning agent prepared from the raw materials of, by weight: 4-5 parts of erucic acid, 3-4 parts of white oil, 3-4 parts of dodecylbetaine, 4-5 parts of fatty alcohol polyoxyethylene ether, 2-3 parts of sodium borate, 3-4 parts of coconut oleic oil alkylolamide phosphate, 2-3 parts of citric acid, 1-2 parts of fatty alcohol polyoxyethylene ether AEO-3, 30-40 parts of ethanol, 4-5 parts of an auxiliary agent, and 150-180 parts of deionized water. The cleaning agent provided by the invention has high-efficiency thorough cleaning function. According to the cleaning agent, a plurality of surfactants are applied in combination, and are well formulated. Therefore, cleaning effect is greatly improved, cleaning efficiency is improved, cleaning cost is saved, and economic benefit is increased. With the auxiliary agent, a protective film can be formed on the surface of the circuit board, such that oxidation and short-circuit can be prevented.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a cleaning agent for 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 limited and there are sa...

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
