Precision electronic device on-line detergent and its production method

Abstract

The invention relates the cleaning agent and preparing method. The cleaning agent comprises 60-80% dichloropropane, 5-20% methylchloro-form and 5-20% difluo-monochloroethane. The cleaning agent has the advantages of good cleaning effect, non remain, and good insulativity. The cleaning agent has good withstand voltage, and the pressure resistance value is 25kv. The cleaning agent solves the problem that moisture coagulated on the surface of substance.

Description

technical field [0001] The invention relates to a cleaning agent, especially a cleaning agent that can be used in an online (charged) state of electronic instruments, and also relates to a production method of the online cleaning agent for precision electronic instruments. Background technique [0002] Circuit boards and other components of precision electronic instruments are often damaged by static electricity and dirt during use and operation: [0003] 1. The hazards of deposited dirt: various dust, smog, organic matter and other pollutants in the air will condense on the circuit board with the air flow and the influence of static electricity, and absorb the moisture in the air on the electronic components and circuit boards of electrical appliances The accumulation of pollutants will cause the circuit to change or terminate the normal signal transmission function, resulting in circuit failure, and even cause interruption, resulting in major losses. [0004] 2. The harm ...

AI Technical Summary

Problems solved by technology

[0003] 1. The hazards of deposited dirt: various dust, smog, organic matter and other pollutants in the air will condense on the circuit board with the air flow and the influence of static electricity, and absorb the moisture in the air on the electronic components and circuit boards of electrical appliances The accumulation of pollutants can cause the circuit to change or terminate the normal signal transmission function, resulting in circuit failure or even interruption, causing major losses

[0004] 2. The harm of static electricity: Electronic equipment will be harmed by cumulative static electricity and charged particles in the working environment. Electrostatic discharge will cause breakdown or performance deterioration of components, especially in high temperature and humid environments, and leakage will occur, even Circuit short circuit, dielectric constant and loss coefficient change, resulting in circuit failure, communication interruption, information loss and other losses

[0007] The traditional cleaning methods for electronic products are mainly blowing with leather tigers, brushing with hair brushes, wiping with alcohol cotton balls, etc. These methods have low distribution efficiency, poor cleaning effect, hidden parts cannot be touched, pollutants are difficult to completely remove, and it is easy to cause artificial damage. In addition, under normal circumstances, it is necessary to stop the machine for maintenance, which affects the normal operation of the equipment

Especially in the case that the equipment must work continuously and cannot be powered off, it is even more difficult to achieve a comprehensive and thorough cleaning

[0008] According to the requirements of equipment cleaning, some live cleaning agents for electrical equipment have appeared on the market, but they have shortcomings in terms of high voltage resistance, high insulation, non-combustibility, non-corrosiveness, and environmental protection. With the improvement of national environmental protection requirements facing elimination
