Printed circuit board cleaning agent and preparation method thereof

Abstract

The invention relates to a printed circuit board cleaning agent. The printed circuit board cleaning agent is prepared from the following raw materials in parts by weight: 30-40 parts of ethanol, 3-4 parts of disodium EDTA (Ethylene Diamine Tetraacetate), 1-2 parts of triethanolamine, 2-4 parts of citric acid, 20-25 parts of propylene glycol, 1-2 parts of sodium lauryl sulfate, 1-2 parts of 4-methyl salicylate, 1-2 parts of boric acid, 4-5 parts of adjuvants and 100-120 parts of deionized water. According to the cleaning agent disclosed by the invention, the preparation method is simple, no adverse effect on the environment is caused, the surface decontamination capacity is strong, the persistence of cleanliness can be maintained, the cleaning speed and durability are increased, and the cleaning effect on metallic ions is relatively strong, so that the subsequent use performance of circuit boards is improved; 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 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
