Problems solved by technology

At present, there are many cleaning agents for printed circuit boards on the market, but there is still a clear gap between domestically produced cleaning agents and foreign developed countries, and some key technologies and core technology products are mostly monopolized by foreign companies, so the price is high
In order to improve the market competitiveness of domestic printed circuit boards, in recent years, scientific research workers in most enterprises and universities in my country have also strengthened the research and development of cleaning agents, such as the multifunctional water-based cleaning agent disclosed in Chinese patent ZL201210197898.7, the cleaning agent It is prepared by using diethylene glycol monobutyl ether, monoethanolamine, octyl p

Abstract

The invention discloses an environment-friendly water-based cleaning agent for printed circuit boards. The environment-friendly water-based cleaning agent is composed of, by weight, 45-50% of alcohol ether, 20-25% of a solubilizer, 1-2% of alkylamine, 1-2% of a gemini surfactant and 21-32% of deionized water, wherein the sum of the weight percentages is 100%. The environment-friendly water-based cleaning agent is effective in cleaning of residual flux, metal ions, granular pollutants, nonpolar and polar residues and the like on surfaces of the printed circuit boards and is free of phosphorus containing compounds, toxicity and corrosion, safety, environment friendly and extensive in application range.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents for the electronics industry, and in particular relates to an environment-friendly water-based cleaning agent for cleaning PCB boards in the electronics industry. Background technique [0002] As an indispensable core component of electronic products, printed circuit board (PCB) is not only the support of electronic components, but also the carrier of electrical connection of electronic components. With the continuous development of the electronics industry, the requirements for the performance of electronic devices have become more stringent. Electronic components are gradually developing towards the trend of miniaturization, fine pitch and high integration. The distance between adjacent conductors is reduced, making the circuit The impact of residue and other contamination on boards on their quality performance has become more pronounced than ever. For example, during the assembly and w...
