Problems solved by technology

Trichlorethylene-based cleaning agents have the advantages of no flash point, fast volatilization, and strong solvency. However, trichlorethylene-based cleaning agents are extremely harmful to the human body, and they are easy to operate in poor operating environments for workers and poor ventilation. occupational disease
In addition, trichlorethylene cleaning agents have a destructive effect on the environment. During the cleaning process, chlorine ions will be released and acidified, causing corrosion of electronic components, and the insulation performance of electronic products will decrease, resulting in defective electronic products.

Abstract

The invention provides a circuit board cleaning agent replacing trichloroethylene. The circuit board cleaning agent replacing the trichloroethylene comprises the following components in mass percentage: 15-60% of cycloalkane, 10-20% of ether additive, 10-20% of ketone additive, 5-15% of ester additive and 15-30% of polyfunctional group additive. The circuit board cleaning agent is excellent in cleaning ability for residual fluxing agent and rosin on a circuit board in electronic industry, high in cleaning speed, rapid in evaporation, free of residue, low in toxicity, environment-friendly and efficient.

Description

technical field [0001] The invention relates to the technical field of cleaning agents used in the electronics industry, in particular to a circuit board cleaning agent that replaces trichlorethylene, and the cleaning agent is suitable for cleaning residual rosin and flux after welding electronic circuit boards. Background technique [0002] At present, the electronics industry mainly uses trichlorethylene-based cleaning agents to clean pollutants such as rosin and flux on circuit boards. Trichlorethylene-based cleaning agents have the advantages of no flash point, fast volatilization, and strong solvency. However, trichlorethylene-based cleaning agents are extremely harmful to the human body. Occupational diseases occur. In addition, trichlorethylene-based cleaning agents have a destructive effect on the environment. During the cleaning process, chlorine ions will be released and acidified, causing corrosion of electronic components, reducing the insulation performance of ...
