Quick circuit board cleaning agent and preparation method thereof

Abstract

The invention relates to a quick circuit board cleaning agent. The quick circuit board cleaning agent is prepared from the following raw materials in parts by weight: 15-20 parts of 1,1,2-trichlorotrifluoroethane, 12-15 parts of menthol, 30-40 parts of ethanol, 2-3 parts of sodium polyacrylate, 1-2 parts of alkenyl succinic acid, 20-24 parts of propylene glycol, 20-25 parts of propanediol butyl ether, 2-3 parts of diffusant NNO, 3-4 parts of sodium dioctyl succinate sulfonate, 4-5 parts of adjuvants and 100-120 parts of deionized water. The cleaning agent disclosed by the invention has the advantages that the effect of cleaning residual contaminants on printed circuit boards is good, the cleaning agent is non-corrosive, electronic devices on the printed circuit boards are difficultly damaged, the requirements for environmental protection are met, and the preparation process is simple; the cleaning agent is of a water emulsion type, so that the cost is low; the adjuvants of the cleaning agent can form a protective film on the surface of a circuit board, so as to isolate air to prevent water and other molecules in the atmosphere from corroding the circuit board to resist oxidation and prevent short circuit, and the implementation of a next production process is facilitated.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a fast 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 ris...

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
