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

Abstract
A water-based strong-lysotype circuit board cleaning agent is manufactured by the following raw materials, by weight: 30-35 parts of 1,1,2-trichloro trifluoroethane, 20-25 parts of nitromethane, 20-25 parts of n-butyl alcohol, 2-3 parts of dodecyl dimethyl amine oxide, 2-3 parts of triethanolamine, 1 to 2 parts of 1,4-butanedioic acid sodium sulfonate, 2-3 parts of oxalic acid, 4-5 parts of inositol hexaphosphate, 1 part to 2 parts of sodium silicate, 4-5 parts of auxiliaries and 100-120 parts of deionized water. The water-based cleaning agent gives play to dissolution characteristic of solution, embodies the characteristics that water is free of flashing point and good in safety, and can be effectively applied to cleaning welding agents, rosin, organics and fingerprints on circuit boards. A cleaning technique of the cleaning agent uses an ultrasonic or spraying method, so that the effects of the cleaning agent can be fully played. The cleaning agent can form protection films on the surfaces of the circuit boards.
Description
technical field [0001] The invention relates to the field of cleaning agents, in particular to a water-based strongly soluble 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 ...
