Electronic instrument panel surface detergent

Abstract

The invention provides a cleaner for the surface of an electronic instrument panel, comprising solubilizer, surface active agent, pH value regulator, antifoaming agent and deionized water; the weight percentage of all the components is as follows: 3 percent to 10 percent of the solubilizer, 3 percent to 12 percent of the surface active agent, 2 percent to 8 percent of the pH value regulator, 2 percent to 8 percent of the antifoaming agent and the rest is the deionized water; the cleaner is water soluble liquid and the pH value thereof is 11 to 12; the cleaner is applicable to the cleaning technique of the surface of the electronic instrument panel, can effectively remove the pollutants including rosin, soldering tin, oil stain, finger prints and solid particles and the like stained on the surface of the electronic instrument panel, has good permeability and thorough cleaning, is not easy to generate residue, has little corrosion, safe and reliable use and no damage to the ozone layer, meets the requirements of environment protection and has reasonable formulation design, simple preparation technique and low cost.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a water-soluble electronic instrument panel surface cleaning agent. Background technique [0002] The electronic instrument panel is a printed circuit board (PCB for short). The main function of the printed circuit board is to fix various electronic components in the electronic instrument and provide the mutual electrical connection of the components arranged on it. With the continuous advancement of science and technology, electronic instruments have more and more functions, making the number of components on the electronic instrument panel more and more, the feature size is getting smaller and smaller, and the requirements for precision are getting higher and higher. , so the reliability of electronic instruments is also put forward higher requirements. The cleanliness of the electronic instrument panel is one of the most important factors affecting the quality and reliability of the elect...

AI Technical Summary

Problems solved by technology

Among them, solder pollution will narrow the distance between devices and easily cause short circuit or open circuit of the instrument.

[0003] At present, the more general cleaning method for electronic instrument panels is to use a single organic reagent to dissolve rosin, solder, oil and other pollutants. This cleaning method is effective for cleaning general printed circuit boards.

For electronic instrument panels with large integration and high precision, it is difficult for this single organic reagent to completely remove other solid particles other than organic matter, and its permeability is poor, and the cleaning effect on narrow places is not good, and it is easy to Causes organic residues, so it is increasingly unable to meet the needs of electronic instrument panel cleaning

In addition, most of the current organic solvent-based cleaning agents for electronic instrument panels are ozone-depleting substances (ODS), which cannot meet environmental protection requirements.
