Circuit board cleaning agent and preparation method thereof

Abstract

The invention belongs to the technical field of cleaning agents and relates to a circuit board cleaning agent and a preparation method thereof. The circuit board cleaning agent comprises, by weight, 50-80 parts of cyclohexane, 10-30 parts of diacetone alcohol, 1-5 parts of diethylene glycol monobutyl ether and 5-20 parts of anhydrous ethanol. The circuit board cleaning agent can fast remove oil stain, scolding tin and rosin, can guarantee a good cleaning rate and good cleaning effects, belongs to a low-toxicity and eco-friendly cleaning agent and produces small damage on the human body. The preparation method has simple processes, utilizes easily available raw materials, has simple preparation processes and a low production cost and is conducive to general popularization application.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, in particular to a cleaning agent for circuit boards and a preparation method thereof. Background technique [0002] In recent years, the electronics industry has developed rapidly, and various electronic products have become popular. Electronic circuit boards are the core components of electronic products, and their reliability will directly affect the reliability of the entire electronic product. The cleanliness of electronic circuit boards have a significant impact on its reliability. During the production and welding of electronic circuit boards, rosin, solder, fingerprints, oil and other substances are likely to remain. These substances are likely to cause short circuits or open circuits on electronic circuit boards. cleaning.

AI Technical Summary

Problems solved by technology

[0003] The main raw materials of existing cleaning agents for cleaning electronic circuit boards generally use trichlorethylene, dichloromethane, etc. Although this type of cleaning agent has a good cleaning effect, the toxicity of the raw materials used is high and the risk is large. The physical health of the workers is extremely harmful, especially the strong volatility of dichloromethane, which will seriously affect the health of the workers when inhaled, especially in the conditions where the operating environment of the workers is relatively poor and the ventilation effect is poor, occupational diseases are easy to occur

In addition, this type of cleaning agent also pollutes the environment very much. In order to carry out advanced treatment on it, the requirements for processing equipment and technology are relatively high, which increases the production cost of the enterprise.
